If you lent money to a relative, friend, or colleague in the Philippines and now wonder exactly how much interest you can collect — or if you borrowed informally and face demands that seem far too high — Philippine law provides clear but specific rules. These rules come primarily from the Civil Code and Bangko Sentral ng Pilipinas (BSP) issuances. They protect both lenders seeking fair compensation and borrowers from excessive charges, especially in private transactions between individuals rather than banks or licensed lending companies.

This guide covers when interest is due on private loans, the current legal rate that applies when nothing was written down, how courts handle overly high agreed rates, the practical steps to collect what is owed, and common situations ordinary Filipinos and overseas Filipinos encounter.

Interest Requires a Written Stipulation

Under Article 1956 of the Civil Code, no interest shall be due unless it has been expressly stipulated in writing. This is a strict rule that applies to private loans between individuals.

A verbal agreement such as “I’ll pay you back with 5% interest” or even a casual chat message usually allows recovery of the principal amount lent. However, it does not automatically entitle the lender to collect the agreed “interest for the use of money” (called conventional interest). Courts have consistently upheld this requirement to avoid disputes over what was really said.

The safest and strongest evidence is a written promissory note, loan agreement, or even a simple acknowledgment of debt that clearly states the principal, the interest rate (if any), the due date, and the names of the parties. Notarizing the document adds another layer of strength because a notarized document is presumed authentic and can be enforced more easily.

If there is no written stipulation for interest, the lender can still recover the principal plus legal interest as damages once the borrower defaults.

The Legal Interest Rate When No Rate Was Agreed

When parties do not stipulate any interest rate in writing — or when payment is delayed — the law imposes a standard rate called legal or compensatory interest.

BSP Circular No. 799, Series of 2013 (effective July 1, 2013) sets this rate at six percent (6%) per annum for the loan or forbearance of any money, goods, or credits, and for judgments, in the absence of an express contract as to the rate. This circular amended the older 12% rate that had been in place for decades.

Article 2209 of the Civil Code reinforces this: If the obligation consists in the payment of a sum of money and the debtor incurs in delay, the indemnity for damages is the interest agreed upon, and in the absence of stipulation, the legal interest, which is six percent per annum.

This 6% rate applies to most private individual loans today. It is simple interest (not automatically compounded) and is meant to compensate the lender for the delay in receiving the money, not to punish the borrower.

How Legal Interest Is Computed and When It Starts

Legal interest generally begins to run from the time the borrower is in default (called mora). Under Article 1169 of the Civil Code, default occurs upon:

Extrajudicial demand (for example, a formal demand letter sent by the lender), or
Judicial demand (the filing of a complaint in court).

Once default occurs, the 6% legal interest accrues on the outstanding principal until the full obligation is paid.

If interest has already accrued and the lender later files a court case, that accrued interest can itself earn legal interest from the date of judicial demand under Article 2212 of the Civil Code.

The Supreme Court refined these rules in Nacar v. Gallery Frames (G.R. No. 189871, August 13, 2013). For obligations arising or becoming due on or after July 1, 2013, the 6% rate generally applies uniformly from default until full payment. Interest is calculated on a simple basis unless the parties expressly agreed to compounding in writing.

Example: You lent ₱100,000 with no written interest agreement. You sent a formal demand letter on January 15, 2025, and the borrower paid on January 15, 2026. Legal interest would be ₱100,000 × 6% × 1 year = ₱6,000. Total due: ₱106,000.

What If the Parties Agreed on a High Interest Rate in Writing?

Parties to a private loan enjoy freedom to stipulate any interest rate in writing. However, this freedom is not unlimited. The Supreme Court has long held that grossly excessive or unconscionable interest rates are void for being contrary to morals and public policy, even if both parties initially agreed.

There is no fixed numerical ceiling for purely private loans (the old Usury Law ceilings were suspended decades ago). Courts decide case by case, looking at the circumstances, the relationship of the parties, the purpose of the loan, and how much the rate exceeds prevailing market or legal rates.

In practice:

Rates around 24% per annum or lower are often upheld if clearly agreed in writing.
Rates of 36% per annum (3% per month) or higher frequently face scrutiny and have been reduced or struck down in several Supreme Court decisions when they appear one-sided or exploitative.
Extremely high rates such as 5% or 6% per month (60–72% per year) are routinely reduced by courts to the legal rate or another reasonable figure.

If you are the lender and included a high rate, be prepared for a borrower to challenge it in court. If you are the borrower facing collection on a very high rate, you have a strong basis to ask the court to reduce it.

Step-by-Step: Collecting on a Private Loan

Here is the typical process most individuals follow when a private loan is not repaid:

Gather and organize your evidence — Written agreement or promissory note, proof the money was actually given (bank transfer, cash acknowledgment receipt, witnesses), text messages or emails about the loan and demands, and any previous partial payments.
Send a formal demand letter — Preferably notarized. Clearly state the amount owed, any interest claimed, and give a reasonable deadline (usually 15–30 days). Keep proof of receipt (registered mail, personal delivery with acknowledgment, or even screenshots of delivery if sent electronically in some cases). This letter usually triggers the start of legal interest if none was stipulated.
Attempt barangay conciliation if required — For most civil disputes involving money between individuals who reside in the same city or municipality, the law requires prior conciliation at the barangay level (Lupong Tagapamayapa) before filing in court. Attend the hearings. If no settlement is reached, request a Certification to File Action (CFA). This step is mandatory in most private loan cases and helps filter out disputes that can be settled amicably.
File the appropriate court case:
- If the principal amount claimed is ₱1,000,000 or less (exclusive of interest and costs), file under the small claims procedure in the Metropolitan Trial Court, Municipal Trial Court, or Municipal Circuit Trial Court. This is faster, simpler, and usually does not require a lawyer. Hearings are often scheduled quickly, and decisions can come within weeks to a couple of months.
- For larger amounts, file a regular civil action for sum of money (venue is usually where the defendant resides or where the obligation was incurred or to be performed).
Attend the proceedings and enforce the judgment — Present your evidence clearly. If you win, the court will issue a decision awarding the principal plus any interest the judge finds proper. Once final, you can move for execution (garnishment of bank accounts, levy on personal property, etc.).

Timelines vary. Barangay processes can take several weeks to a few months. Small claims cases are designed to be expedited. Regular court cases take longer, sometimes a year or more if contested heavily.

Common Pitfalls and Real-Life Scenarios

Lending to family without any writing — You can still recover the principal and 6% legal interest from the date of formal demand. Many people lose the chance to claim higher interest because they relied only on verbal promises or family trust.

Charging very high rates informally — A borrower who later faces collection can ask the court to reduce the rate. Judges often do so when the rate appears exploitative relative to the legal 6% benchmark.

Delaying the demand letter — Legal interest usually does not start until you formally demand payment. Simply waiting for years without action can limit the interest you ultimately recover.

Borrower side — If you are being sued and the claimed interest looks excessive, raise the issue of unconscionability as a defense. Courts have the power to reduce it.

Partial payments — Always document them clearly. Unexplained partial payments can sometimes be applied first to interest then to principal, depending on the agreement or court ruling.

Special Notes for Foreigners and Overseas Filipinos

Philippine law generally applies to loans made or payable in the Philippines, regardless of the nationality of the parties. If you are an overseas Filipino lending to someone in the Philippines, the same Civil Code and BSP rules apply.

Documents executed abroad that you want to use as evidence in a Philippine court may need apostille authentication under the Hague Apostille Convention (which the Philippines has joined). Enforcement of a Philippine judgment abroad depends on the laws of the foreign country and any applicable treaties.

If the borrower has assets or resides in the Philippines, collection through Philippine courts is usually straightforward once jurisdiction is established. Constitutional restrictions on foreign ownership do not normally affect simple money claims.

Frequently Asked Questions

Can I charge interest on a loan to my friend or sibling if we only agreed verbally?
For conventional interest (payment for the use of the money), generally no — Article 1956 requires a written stipulation. You can still recover the principal plus 6% legal interest from the date of a formal demand letter.

What is the maximum interest rate allowed on a private loan between individuals?
There is no fixed statutory maximum. You may agree on any reasonable rate in writing. However, courts can reduce or nullify rates they find unconscionable or grossly excessive under the circumstances, often bringing them down toward the 6% legal rate or another equitable figure.

From what exact date does the 6% legal interest start if there was no written agreement?
It generally starts from the date the borrower receives a formal demand for payment or from the date you file a court case, whichever occurs first, and continues until full payment.

Is compound interest allowed on private loans?
Only if the parties expressly stipulated it in writing. Legal interest (the 6% rate) is normally simple interest. Accrued interest can earn further legal interest once a court case is filed.

Do I always have to go through the barangay before filing a court case for an unpaid loan?
In most cases involving individuals residing in the same city or municipality, yes — prior barangay conciliation is mandatory. You will need a Certification to File Action if no settlement is reached.

What happens in small claims court for loan collection?
If the principal amount is ₱1,000,000 or less (excluding interest and costs), you can use the simplified small claims procedure in first-level courts. It is faster, more affordable, and designed for straightforward money claims. Lawyers are not required in most instances.

Can a foreigner or overseas Filipino collect on a private loan made in the Philippines?
Yes. Philippine courts apply the same rules. You may need to apostille foreign documents and ensure proper service of summons on the borrower in the Philippines.

If the loan was made before July 2013, which interest rate applies?
The old 12% rate generally applied until June 30, 2013. From July 1, 2013 onward, the 6% rate under BSP Circular No. 799 applies to the period after that date (with specific computation rules explained in Nacar v. Gallery Frames).

Can the borrower be made to pay attorney’s fees or other expenses?
In some cases, yes — if the loan agreement provides for it or if the court finds the borrower acted in bad faith or with gross negligence. These are not automatic and depend on the facts and the judge’s discretion.

Key Takeaways

Interest on private loans between individuals generally requires an express written stipulation under Article 1956 of the Civil Code.
When no interest rate is stipulated in writing, or when payment is delayed, the legal interest rate is 6% per annum under BSP Circular No. 799 and Article 2209 of the Civil Code.
Legal interest typically begins from formal demand or court filing and runs until full payment.
Even written high interest rates can be reduced by courts if found unconscionable.
Proper documentation (especially a notarized promissory note) and a formal demand letter significantly strengthen any collection effort.
Most private loan collection cases between individuals require prior barangay conciliation before court action.
For claims of ₱1,000,000 or less in principal, the small claims procedure offers a faster and simpler path in first-level courts.
Both lenders and borrowers benefit from understanding these rules early — clear written agreements prevent most disputes, while knowledge of the 6% legal rate and unconscionability doctrine protects against unfair outcomes.

Understanding these rules puts you in a stronger position whether you are trying to recover money fairly owed or responding to a claim that includes questionable interest charges. The Philippine legal system aims for balance: compensating lenders for the use and delay of their money while protecting borrowers from exploitation.
