I. Overview

In the Philippines, minimum wage is generally fixed on a daily basis, not monthly. This is because minimum wage rates are issued by the Regional Tripartite Wages and Productivity Boards through wage orders, and these wage orders usually state the minimum wage as an amount per day.

However, many employees are paid on a semi-monthly or monthly payroll cycle. This creates a common question:

How do you convert a daily minimum wage into a monthly salary?

The answer depends on several legal and practical factors, including:

Whether the employee is paid for rest days and holidays;
Whether the employee is a monthly-paid or daily-paid employee;
The applicable regional minimum wage;
The employee’s work schedule;
Whether the establishment operates six days a week, five days a week, or continuously;
Whether the employee is entitled to holiday pay, service incentive leave, 13th month pay, overtime, night shift differential, premium pay, and other labor standards benefits.

There is no single monthly equivalent that applies to all employees in all situations. The computation must be based on the employee’s pay arrangement and the legally compensable days in a year.

II. Legal Basis of Minimum Wage in the Philippines

The Philippine Constitution recognizes labor as a primary social economic force and mandates the State to protect workers’ rights.

The Labor Code of the Philippines, as amended, provides for minimum labor standards, including:

Minimum wage;
Hours of work;
Overtime pay;
Night shift differential;
Weekly rest periods;
Holiday pay;
Service incentive leave;
13th month pay;
Premium pay for rest days and special days.

Minimum wages are set regionally. This means that the minimum wage in Metro Manila may be different from the minimum wage in Central Luzon, CALABARZON, Central Visayas, Davao Region, or other regions.

The applicable rate is usually determined by:

The location of the establishment;
The industry or sector;
The size or classification of the employer, when the wage order provides distinctions;
Whether the employee is in agriculture, non-agriculture, retail/service, manufacturing, or another covered sector.

III. Daily Minimum Wage Versus Monthly Salary

A daily minimum wage is the minimum amount that must be paid for a normal working day.

A monthly salary is a fixed amount paid for a month, usually regardless of the number of working days in that month, subject to lawful deductions for absences, tardiness, undertime, and unpaid leaves.

The key distinction is this:

A daily-paid employee is generally paid only for days actually worked, subject to holiday pay rules.

A monthly-paid employee is generally paid a fixed monthly salary that may already include payment for rest days, regular holidays, and special non-working days, depending on the employment arrangement and payroll structure.

IV. Why Monthly Equivalent Matters

The monthly equivalent of a daily minimum wage is commonly needed for:

Payroll setup;
Employment contracts;
Payslip preparation;
Minimum wage compliance;
13th month pay computation;
SSS, PhilHealth, and Pag-IBIG contribution brackets;
Overtime, holiday, rest day, and night shift differential computations;
Separation pay;
Retirement pay;
Back wage computation in labor cases.

However, the monthly equivalent should not be used to deprive employees of statutory benefits. An employer cannot simply multiply the daily minimum wage by an arbitrary number and declare compliance. The computation must reflect the legally compensable days applicable to the employee.

V. Basic Formula

The general formula is:

Monthly Equivalent = Daily Wage × Equivalent Working Days in a Year ÷ 12

The crucial variable is the equivalent working days in a year.

Different types of employees use different annual factors.

VI. Common Monthly Equivalent Factors

The Department of Labor and Employment has historically recognized several annualization factors for converting daily wage to monthly equivalent.

The most commonly used factors are:

1. 313 days

Usually used for employees who are required to work every day, including Sundays or rest days, special days, and regular holidays, where these days are considered paid.

Formula:

Monthly Salary = Daily Wage × 313 ÷ 12

This factor may apply where the employee is paid for:

298 ordinary working days;
12 regular holidays;
3 special days.

This is often used for workers whose compensation structure treats these days as paid in the monthly equivalent.

2. 365 days

Used for monthly-paid employees who are paid every day of the year, including rest days, regular holidays, and special days.

Formula:

Monthly Salary = Daily Wage × 365 ÷ 12

This factor assumes that the employee’s monthly salary covers all calendar days of the year.

This is common for monthly-paid employees whose pay does not fluctuate based on the number of working days in a month.

3. 261 days

Often used for employees who work five days a week and are not paid for rest days and certain non-working days unless worked or otherwise legally compensable.

Formula:

Monthly Salary = Daily Wage × 261 ÷ 12

This generally reflects a five-day workweek arrangement.

4. 314 days

Sometimes used depending on the number of special days and applicable rules in a given year or policy structure.

Formula:

Monthly Salary = Daily Wage × 314 ÷ 12

Because holidays and special days may change by law or proclamation, employers should be careful in using this factor without checking the applicable rules for the relevant year.

5. 262 or 260 days

Some employers use 260 or 262 days for five-day workweek employees.

Formula:

Monthly Salary = Daily Wage × 260 ÷ 12

Monthly Salary = Daily Wage × 262 ÷ 12

These are often business or payroll conventions, but the legal sufficiency depends on whether the employee is receiving all required statutory benefits.

VII. Determining the Correct Factor

The correct factor depends on whether the employee is paid for non-working days.

A. Six-day workweek, paid only for days worked

For an employee working six days a week, the usual annual working days may be around 313 days, depending on the treatment of holidays and special days.

Formula:

Monthly Equivalent = Daily Minimum Wage × 313 ÷ 12

Example:

Daily minimum wage: ₱610 Annual factor: 313 days

₱610 × 313 = ₱190,930 ₱190,930 ÷ 12 = ₱15,910.83

Monthly equivalent: ₱15,910.83

B. Five-day workweek, paid only for working days

For an employee working five days a week, the factor may be 261 days.

Formula:

Monthly Equivalent = Daily Minimum Wage × 261 ÷ 12

Example:

Daily minimum wage: ₱610 Annual factor: 261 days

₱610 × 261 = ₱159,210 ₱159,210 ÷ 12 = ₱13,267.50

Monthly equivalent: ₱13,267.50

C. Monthly-paid employee paid for all calendar days

For an employee whose salary covers all days of the year, including rest days and holidays, the factor is commonly 365 days.

Formula:

Monthly Equivalent = Daily Minimum Wage × 365 ÷ 12

Example:

Daily minimum wage: ₱610 Annual factor: 365 days

₱610 × 365 = ₱222,650 ₱222,650 ÷ 12 = ₱18,554.17

Monthly equivalent: ₱18,554.17

VIII. Monthly-Paid Employees and Daily-Paid Employees

A. Daily-paid employees

A daily-paid employee is paid based on the number of days actually worked, subject to labor standards rules on paid regular holidays and other benefits.

For daily-paid employees:

No work, no pay generally applies;
Regular holidays may still be paid if conditions are met;
Special non-working days are usually unpaid unless worked or unless a favorable company policy, contract, or collective bargaining agreement applies;
Rest days are unpaid unless worked or unless included by agreement;
Overtime and premium pay are computed based on the daily rate and hourly rate.

B. Monthly-paid employees

A monthly-paid employee receives a fixed monthly salary. The salary may be deemed to cover every day of the month, including rest days and holidays, depending on the terms of employment.

For monthly-paid employees:

The salary is fixed regardless of the number of working days in a month;
The employee is usually paid for regular holidays even if not worked;
The monthly rate may include pay for rest days and non-working days;
Absences, tardiness, and undertime may be deducted if allowed by law and company policy;
Overtime and other premiums must still be paid if the employee is non-exempt and renders compensable work beyond normal hours or on premium days.

IX. The Role of the Employment Contract

The employment contract should state whether the employee is:

Daily-paid;
Monthly-paid;
Paid on a five-day or six-day workweek;
Entitled to pay on rest days and holidays;
Receiving a salary that already includes certain legally paid days;
Covered by a compressed workweek or flexible work arrangement.

The employer should avoid vague salary clauses. For example, saying “₱15,000 monthly salary” without explaining the covered workdays may create confusion if the amount is close to the minimum wage threshold.

A better clause would state:

“The employee shall be paid a monthly salary of ₱____, equivalent to the applicable daily minimum wage multiplied by the legally applicable annual factor divided by twelve, subject to statutory benefits, deductions, and premium pay as required by law.”

X. Minimum Wage Compliance

To determine whether a monthly salary complies with minimum wage, compare the employee’s monthly salary against the proper monthly equivalent of the applicable daily minimum wage.

The employer should not simply compare the monthly salary to one fixed number without considering the employee’s work schedule.

For example, if the daily minimum wage is ₱610:

Basis	Formula	Monthly Equivalent
261 days	₱610 × 261 ÷ 12	₱13,267.50
313 days	₱610 × 313 ÷ 12	₱15,910.83
365 days	₱610 × 365 ÷ 12	₱18,554.17

Thus, a ₱15,000 monthly salary may be compliant under one arrangement but deficient under another.

XI. How to Compute the Daily Rate From Monthly Salary

Sometimes the reverse computation is needed.

The formula is:

Daily Rate = Monthly Salary × 12 ÷ Annual Factor

Example:

Monthly salary: ₱18,000 Annual factor: 313 days

₱18,000 × 12 = ₱216,000 ₱216,000 ÷ 313 = ₱690.10

Daily rate: ₱690.10

For a 365-day monthly-paid employee:

₱18,000 × 12 = ₱216,000 ₱216,000 ÷ 365 = ₱591.78

Daily rate: ₱591.78

This shows why the annual factor matters. The same monthly salary may produce different daily rates depending on whether the employee is paid for 261, 313, or 365 days.

XII. How to Compute the Hourly Rate

The usual formula is:

Hourly Rate = Daily Rate ÷ 8

Example:

Daily rate: ₱610 ₱610 ÷ 8 = ₱76.25

Hourly rate: ₱76.25

This hourly rate is used for computing:

Overtime pay;
Night shift differential;
Rest day premium;
Regular holiday pay;
Special day premium;
Undertime deductions;
Late deductions.

XIII. Overtime Pay

For covered employees, work beyond eight hours in a day is compensable as overtime.

Basic formula for ordinary day overtime:

Hourly Rate × 125% × Number of Overtime Hours

Example:

Hourly rate: ₱76.25 Overtime hours: 2

₱76.25 × 125% = ₱95.31 ₱95.31 × 2 = ₱190.62

Overtime pay: ₱190.62

Overtime rates differ when overtime is performed on rest days, special days, or regular holidays.

XIV. Regular Holiday Pay

Regular holidays are generally paid even if the employee does not work, provided the employee satisfies the conditions under the rules.

For covered employees:

A. If not worked

Daily Wage × 100%

Example:

₱610 × 100% = ₱610

B. If worked

Daily Wage × 200%

Example:

₱610 × 200% = ₱1,220

C. If worked beyond eight hours on a regular holiday

The overtime rate is computed on the holiday rate.

Basic concept:

Hourly Rate × 200% × 130% × Overtime Hours

The applicable rate may differ depending on whether the holiday falls on a rest day.

XV. Special Non-Working Day Pay

For special non-working days, the general rule is:

No work, no pay, unless there is a favorable company policy, employment contract, collective bargaining agreement, or practice.

A. If not worked

Usually no pay, unless otherwise provided.

B. If worked

The employee is generally entitled to an additional 30% of the basic wage for the first eight hours.

Formula:

Daily Wage × 130%

Example:

₱610 × 130% = ₱793

C. If the special day is also the employee’s rest day

Formula:

Daily Wage × 150%

Example:

₱610 × 150% = ₱915

XVI. Rest Day Pay

If an employee works on a scheduled rest day, the employee is generally entitled to an additional premium.

Formula:

Daily Wage × 130%

Example:

₱610 × 130% = ₱793

If overtime is performed on a rest day, the overtime premium is computed on the rest day rate.

XVII. Night Shift Differential

Covered employees who work between 10:00 p.m. and 6:00 a.m. are generally entitled to night shift differential.

Formula:

Hourly Rate × 10% × Number of Night Shift Hours

Example:

Hourly rate: ₱76.25 Night shift hours: 4

₱76.25 × 10% = ₱7.625 ₱7.625 × 4 = ₱30.50

Night shift differential: ₱30.50

Night shift differential may stack with overtime, rest day, holiday, or special day premiums depending on the circumstances.

XVIII. 13th Month Pay

Rank-and-file employees are generally entitled to 13th month pay, regardless of designation or employment status, provided they worked for at least one month during the calendar year.

Formula:

13th Month Pay = Total Basic Salary Earned During the Calendar Year ÷ 12

For minimum wage earners, 13th month pay is based on basic salary actually earned, excluding items that are not part of basic salary, such as:

Overtime pay;
Holiday premium;
Night shift differential;
Allowances not integrated into basic salary;
Cash equivalent of unused leave credits, unless treated as salary by policy;
Other non-basic wage benefits.

Example:

Monthly basic salary: ₱15,910.83 Months worked: 12

₱15,910.83 × 12 = ₱190,929.96 ₱190,929.96 ÷ 12 = ₱15,910.83

13th month pay: ₱15,910.83

For employees who did not work the full year, use only the basic salary actually earned during the year.

XIX. Service Incentive Leave

Employees who have rendered at least one year of service are generally entitled to five days of service incentive leave with pay, unless they are already enjoying an equivalent or more favorable leave benefit.

Service incentive leave is important in minimum wage computations because it may affect annual pay, especially where unused leave is convertible to cash.

However, service incentive leave is not usually included in the simple daily-to-monthly minimum wage conversion unless the employer’s payroll structure expressly annualizes it.

XX. Allowances and Wage-Related Benefits

Some wage orders include cost of living allowances or other wage-related components.

When computing monthly equivalent, determine whether the wage order provides:

Basic wage only;
Basic wage plus cost of living allowance;
Integration of allowance into basic wage;
Separate allowance not considered part of basic wage for certain purposes.

This matters because certain benefits are computed based on basic wage, while others may include wage-related allowances depending on the rule, wage order, contract, or company practice.

XXI. Minimum Wage Earners and Tax

Minimum wage earners are generally exempt from income tax on their statutory minimum wage, including certain statutory benefits such as holiday pay, overtime pay, night shift differential, and hazard pay, subject to tax rules.

However, if the employee earns above the statutory minimum wage or receives taxable compensation beyond exempt items, tax treatment may differ.

Payroll should distinguish between:

Basic minimum wage;
Overtime pay;
Holiday pay;
Night shift differential;
Hazard pay;
Allowances;
Bonuses;
13th month pay and other benefits.

XXII. Deductions From Monthly Salary

Lawful deductions may include:

SSS contributions;
PhilHealth contributions;
Pag-IBIG contributions;
Withholding tax, if applicable;
Absences;
Tardiness;
Undertime;
Authorized salary loans;
Deductions authorized by law, regulation, or written agreement.

Unlawful deductions are prohibited. Employers cannot shift ordinary business losses, breakages, cash shortages, or operational costs to employees unless allowed under strict legal conditions.

XXIII. No Work, No Pay Principle

The “no work, no pay” principle generally applies to days when the employee does not work and there is no law, contract, policy, or practice requiring payment.

However, this principle is subject to exceptions, including:

Regular holiday pay;
Paid leave;
Paid suspension under certain circumstances;
Company policy;
Collective bargaining agreement;
Employment contract;
Established employer practice;
Monthly salary arrangement covering non-working days.

Thus, the effect of absences differs between daily-paid and monthly-paid employees.

XXIV. Five-Day Workweek Issues

For a five-day workweek employee, the monthly equivalent is often lower than that of a six-day workweek employee because the employee has fewer paid workdays in a year.

Example using ₱610 daily wage:

Five-day factor: 261 days Monthly equivalent: ₱610 × 261 ÷ 12 = ₱13,267.50

Six-day factor: 313 days Monthly equivalent: ₱610 × 313 ÷ 12 = ₱15,910.83

This does not necessarily mean the five-day employee is underpaid. The employee simply has fewer regular working days. However, if the employee works beyond the five-day schedule, proper premium, overtime, rest day, or holiday pay may be due.

XXV. Six-Day Workweek Issues

A six-day workweek is common in retail, manufacturing, construction, restaurants, logistics, and service establishments.

For six-day employees, the employer must ensure payment for:

Six ordinary working days per week;
Regular holidays, whether worked or not, subject to rules;
Special days if worked;
Rest day premium if the rest day is worked;
Overtime if work exceeds eight hours;
Night shift differential if applicable;
13th month pay;
Other statutory benefits.

The 313-day factor is often used for this type of arrangement, but employers should still verify the actual compensable days and applicable wage order.

XXVI. Compressed Workweek

A compressed workweek allows the normal workweek to be completed in fewer than six days, often by extending daily work hours without overtime, subject to legal requirements and employee consent.

For example, employees may work four or five days a week, with daily work exceeding eight hours, while total weekly hours do not exceed the regular weekly schedule.

In such cases, monthly salary computation must be carefully structured. The daily minimum wage conversion may not be enough because the workday is longer than the ordinary eight-hour day.

Important points:

A valid compressed workweek should comply with labor rules;
It should not reduce existing benefits;
Employees should voluntarily agree;
The arrangement should not result in payment below the minimum wage;
Overtime may still apply if work exceeds the approved compressed schedule.

XXVII. Part-Time Employees

Part-time employees are also entitled to minimum wage protection, proportionate to the hours worked.

For part-time employees, compute the hourly rate from the daily minimum wage.

Formula:

Hourly Minimum Wage = Daily Minimum Wage ÷ 8

Example:

Daily minimum wage: ₱610 Hourly minimum wage: ₱610 ÷ 8 = ₱76.25

If the part-time employee works four hours:

₱76.25 × 4 = ₱305

A part-time employee cannot be paid below the applicable hourly minimum wage.

XXVIII. Probationary Employees

Probationary employees are entitled to the applicable minimum wage. Probationary status does not justify payment below the minimum wage.

They are also entitled to statutory labor standards benefits, including overtime pay, holiday pay, rest day premium, night shift differential, and 13th month pay, when applicable.

XXIX. Apprentices and Learners

Apprentices and learners may be subject to special rules under the Labor Code. In certain lawful apprenticeship or learnership arrangements, compensation may be lower than the regular minimum wage if allowed by law and approved under applicable requirements.

Employers should not label a worker as an apprentice or learner merely to avoid minimum wage compliance. The arrangement must satisfy legal requirements.

XXX. Domestic Workers

Domestic workers, or kasambahay, are governed by a special law and have their own minimum wage standards, which are not necessarily the same as the regional daily minimum wage for private establishments.

Their compensation is usually stated monthly, not daily, and the applicable minimum depends on the location and current wage orders for domestic workers.

XXXI. Workers Paid by Results, Piece Rate, or Commission

Workers paid by results, including piece-rate workers, pakyaw workers, and certain commission-based workers, must still receive at least the equivalent of the applicable minimum wage for the hours or days worked.

Employers should ensure that output-based pay does not fall below minimum wage.

Where necessary, the employer should perform a time-and-motion study or equivalent wage determination to confirm compliance.

XXXII. Common Mistakes in Computing Monthly Salary

1. Using 22 days for all employees

Some employers compute monthly salary as:

Daily wage × 22 days

This may be appropriate only for certain internal approximations but is not a complete legal annualization method. It may understate wages for employees whose salary should include holidays or other paid days.

2. Ignoring regular holidays

Regular holidays are legally significant. A daily-paid employee may be entitled to holiday pay even if no work is performed, subject to conditions.

Ignoring holiday pay can result in underpayment.

3. Treating special days as always unpaid

Special non-working days are generally unpaid if not worked, but if the employee works, premium pay is required. Company policy or contract may also provide payment even if not worked.

4. Assuming monthly salary includes all premiums

A fixed monthly salary does not automatically include overtime, night shift differential, rest day premium, holiday premium, or special day premium.

These benefits must still be paid unless the employee is legally exempt or the salary structure lawfully and clearly includes them without reducing statutory entitlements.

5. Misclassifying employees as managerial

Managerial employees and certain officers or staff may be exempt from some labor standards benefits, but rank-and-file employees are generally covered.

A job title alone does not determine exemption. Actual duties matter.

6. Using an outdated minimum wage rate

Minimum wages change by region through wage orders. Employers must use the applicable current wage order for the region and sector.

XXXIII. Sample Full Computation

Assume:

Daily minimum wage: ₱610 Work schedule: six days per week Annual factor: 313 days Normal workday: 8 hours

Step 1: Compute monthly equivalent

₱610 × 313 ÷ 12 = ₱15,910.83

Step 2: Compute hourly rate

₱610 ÷ 8 = ₱76.25

Step 3: Compute ordinary day overtime

Employee worked 2 hours overtime.

₱76.25 × 125% × 2 = ₱190.62

Step 4: Compute work on special non-working day

Employee worked 8 hours on a special non-working day.

₱610 × 130% = ₱793

Step 5: Compute work on regular holiday

Employee worked 8 hours on a regular holiday.

₱610 × 200% = ₱1,220

Step 6: Compute night shift differential

Employee worked 4 night shift hours.

₱76.25 × 10% × 4 = ₱30.50

XXXIV. Payroll Presentation

A compliant payslip should clearly show:

Basic pay;
Number of days or hours worked;
Overtime pay;
Night shift differential;
Holiday pay;
Rest day pay;
Special day pay;
Allowances;
Gross pay;
Statutory deductions;
Other authorized deductions;
Net pay.

For minimum wage employees, transparency is especially important because small payroll errors can result in labor standards violations.

XXXV. Legal Consequences of Underpayment

Failure to pay the minimum wage or related benefits may expose the employer to:

Money claims;
Labor standards inspection findings;
Compliance orders;
Payment of wage differentials;
Administrative penalties;
Attorney’s fees in proper cases;
Possible criminal liability under labor laws;
Damage to employee relations and business reputation.

Employees may file complaints before the appropriate labor office, depending on the amount and nature of the claim.

XXXVI. Practical Rules for Employers

Employers should:

Identify the correct regional wage order;
Determine the employee’s classification and work schedule;
Use the correct annual factor;
State salary structure clearly in the employment contract;
Maintain accurate time records;
Issue proper payslips;
Separately compute overtime, holiday pay, special day pay, rest day premium, and night shift differential;
Update payroll whenever wage orders change;
Avoid using outdated or arbitrary monthly equivalents;
Preserve payroll records for legal compliance.

XXXVII. Practical Rules for Employees

Employees should check:

The applicable minimum wage in their region;
Their employment contract;
Whether they are daily-paid or monthly-paid;
Their work schedule;
Their payslip;
Whether overtime, holiday pay, rest day premium, special day premium, and night shift differential are separately paid;
Whether their 13th month pay is correctly computed;
Whether deductions are lawful and properly explained.

XXXVIII. Core Legal Principle

The central rule is simple:

A monthly salary derived from a daily minimum wage must not result in the employee receiving less than the legally required minimum wage and statutory benefits.

The daily-to-monthly conversion is only a payroll tool. It does not erase the employee’s rights to labor standards benefits.

XL. Conclusion

Computing monthly salary from a daily minimum wage in the Philippines requires more than multiplying the daily rate by 22, 26, or 30 days. The legally sound method is to annualize the daily wage using the correct factor, then divide by twelve.

The proper factor depends on the employee’s work schedule and whether the salary covers only working days, working days plus holidays, or all calendar days. The most common factors are 261, 313, and 365 days, but the correct one depends on the actual employment arrangement.

Employers must ensure that the resulting monthly salary complies with the applicable regional minimum wage and that statutory benefits are separately and correctly paid when due. Employees, in turn, should understand that a monthly salary is not automatically lawful merely because it appears fixed or regular. What matters is whether the total pay structure satisfies Philippine labor standards.
