A 20% monthly interest rate on a loan in the Philippines is a serious red flag. In ordinary language, many people call it “usury.” In strict legal terms, however, the answer is more nuanced: the old Usury Law ceilings are generally suspended, so 20% per month is not automatically “usury” in the old statutory-ceiling sense. But that does not mean the lender can always collect it. Philippine courts can strike down or reduce interest that is excessive, iniquitous, unconscionable, or contrary to morals, and 20% per month is far higher than rates the Supreme Court has already invalidated in many loan cases.
Is 20% Monthly Interest Automatically Illegal in the Philippines?
Not always under the old usury framework, but it is highly vulnerable to challenge.
A 20% monthly interest rate means:
| Loan Amount | 20% Monthly Interest | Interest After 3 Months | Interest After 12 Months, Simple |
|---|---|---|---|
| ₱10,000 | ₱2,000/month | ₱6,000 | ₱24,000 |
| ₱50,000 | ₱10,000/month | ₱30,000 | ₱120,000 |
| ₱100,000 | ₱20,000/month | ₱60,000 | ₱240,000 |
At simple interest, 20% per month is 240% per year. If compounded monthly, ₱10,000 becomes about ₱29,859 after six months and about ₱89,161 after one year. That is why courts often look beyond the words “the borrower agreed” and ask whether the rate is so oppressive that it should not be enforced.
The practical answer is:
- If the lender is a private individual: 20% monthly interest is not automatically void just because it exceeds an old usury ceiling, but a court may reduce or delete it as unconscionable.
- If the lender is a lending company, financing company, or online lending platform covered by SEC/BSP rate-cap rules: 20% monthly interest may violate regulatory ceilings, depending on the loan amount, term, date, and type of loan.
- If there is no written agreement for interest: the lender generally cannot collect the agreed interest at all, because Philippine law requires interest to be expressly stipulated in writing.
- Even if the interest is void or reduced: the borrower usually still owes the principal amount actually received.
What “Usury” Means Under Philippine Law
“Usury” traditionally means charging interest above the maximum rate allowed by law. The Philippines has an old Usury Law, Act No. 2655, but its interest-rate ceilings were effectively suspended by Central Bank Circular No. 905, Series of 1982.
The Supreme Court explained in Advocates for Truth in Lending, Inc. v. Bangko Sentral Monetary Board that Circular No. 905 did not repeal the Usury Law; it suspended the law’s effectivity as to interest ceilings. This means there is generally no old-style universal usury ceiling for ordinary loans.
But this is only half the story.
Philippine courts still review interest rates under the Civil Code. A lender cannot simply say, “There is no usury law anymore, so I can charge anything.” Freedom of contract is not absolute.
Under Article 1306 of the Civil Code of the Philippines, parties may agree on contract terms, but not terms that are contrary to law, morals, good customs, public order, or public policy. If the interest rate shocks the conscience, the court can refuse to enforce it.
The Main Legal Rules on Interest in Philippine Loans
1. Interest must be in writing
Article 1956 of the Civil Code states that no interest shall be due unless it has been expressly stipulated in writing.
This is one of the most important rules for borrowers and lenders.
If the lender says, “We verbally agreed on 20% per month,” but there is no written proof of that interest rate, the lender may have difficulty collecting interest. The principal loan may still be collectible, but the interest may be disallowed.
A written stipulation may appear in:
- a promissory note;
- a loan agreement;
- a signed acknowledgment of debt;
- a text message, email, chat, or electronic document that can be authenticated;
- a notarized document;
- a signed payment schedule;
- a disclosure statement from a financing or lending company.
The clearer the writing, the stronger the lender’s position. But even a written rate can still be reduced if it is unconscionable.
2. The principal debt usually remains valid
If the 20% monthly interest is struck down, the borrower does not automatically get a free loan.
Courts usually separate:
- the principal obligation — the amount actually borrowed; and
- the interest stipulation — the agreed charge for use of the money.
If the court finds the interest excessive, it may delete or reduce the interest while still ordering the borrower to pay the principal.
3. Courts may reduce unconscionable interest and penalties
Article 1229 of the Civil Code allows courts to reduce a penalty when it is iniquitous or unconscionable. Article 2227 also allows the equitable reduction of liquidated damages if they are iniquitous or unconscionable.
This matters because many lenders do not only charge “interest.” They also add:
- penalty interest;
- daily late fees;
- service fees;
- processing fees;
- collection fees;
- attorney’s fees;
- compounding charges;
- “extension” or “rollover” charges.
A loan may look like “20% interest” on paper, but the real cost may be much higher. Courts and regulators can examine the actual economic burden, not just the label used by the lender.
4. Legal interest is generally 6% per year when applicable
In Nacar v. Gallery Frames, the Supreme Court applied the Bangko Sentral’s 6% per annum legal interest rate effective July 1, 2013, when legal interest is proper.
This 6% per year rate does not mean every loan automatically carries 6% interest from the start. For ordinary loans, Article 1956 still requires a written stipulation for conventional interest. But if the borrower is in delay and the obligation is to pay a sum of money, legal interest may apply under Article 2209 of the Civil Code and the Supreme Court’s guidelines.
What the Supreme Court Has Said About Very High Monthly Interest
The Supreme Court has repeatedly invalidated or reduced very high loan interest rates, even when the borrower signed the document.
In Medel v. Court of Appeals, the Court struck down a 5.5% monthly interest rate, equivalent to 66% per year, as iniquitous and unconscionable.
Other cases have applied the same principle to excessive interest and charges. The Court has treated rates such as 3%, 5.5%, and 6% per month as potentially excessive depending on the facts. In Lara’s Gifts & Decors, Inc. v. Midtown Industrial Sales, Inc., the Court again emphasized that stipulated interest rates may be invalidated when unconscionable.
This is important for 20% monthly interest. If the Supreme Court has found much lower monthly rates unconscionable in past cases, a 20% monthly charge will almost certainly need a strong justification. In an ordinary personal loan, salary loan, emergency loan, “5-6” arrangement, or online cash loan, 20% per month is likely to be attacked as excessive.
Is 20% Monthly Interest Void or Just Reduced?
It depends on the facts and how the issue reaches the court.
A court may:
| Situation | Likely Legal Effect |
|---|---|
| No written interest agreement | Interest may be disallowed under Article 1956 |
| Written 20% monthly interest in a private loan | Court may reduce or delete the rate as unconscionable |
| 20% monthly interest plus penalties and compounding | Court may reduce interest, penalties, attorney’s fees, or charges |
| Covered SEC-regulated lending or financing loan exceeds regulatory caps | Possible SEC violation plus civil consequences |
| Borrower already paid excessive interest | Borrower may argue for recomputation and application of excess payments to principal |
| Lender sues in small claims | Borrower must raise unconscionability and attach proof in the Response |
Courts do not always use exactly the same remedy. Some decisions reduce the rate to a reasonable rate. Others delete the stipulated interest and impose legal interest only from demand, filing of the case, or finality of judgment, depending on the circumstances.
SEC and BSP Rules for Lending Companies, Financing Companies, and Online Lending Platforms
A separate set of rules applies to lending companies, financing companies, and their online lending platforms. These are not just “private lenders.” They are regulated entities.
Under Republic Act No. 9474, or the Lending Company Regulation Act of 2007, lending companies need authority to operate. Financing companies are regulated under Republic Act No. 8556, or the Financing Company Act of 1998. The SEC supervises these companies, while the BSP may prescribe ceilings under certain laws and regulations.
BSP Circular No. 1133, Series of 2021, implemented through SEC rules, set ceilings for certain small-value, short-term, unsecured general-purpose loans offered by lending companies, financing companies, and online lending platforms.
For covered loans under those rules, the ceilings included:
| Charge | Ceiling Under BSP Circular No. 1133 / SEC MC No. 3, s. 2022 |
|---|---|
| Nominal interest rate | 6% per month |
| Effective interest rate, including applicable fees | 15% per month |
| Late payment or non-payment penalty | 5% per month on outstanding scheduled amount due |
| Total cost cap | 100% of the total amount borrowed |
The SEC later issued recalibrated rules under SEC Memorandum Circular No. 14, Series of 2025, for covered financing and lending company loans. For covered small, unsecured, general-purpose loans entered into, restructured, or renewed beginning April 1, 2026, the recalibrated ceilings generally include a 6% monthly nominal interest ceiling, a lower effective interest rate ceiling, a 5% monthly penalty cap, and a total cost cap.
The key point for borrowers is this: if a registered lending company, financing company, or online lending app charges 20% monthly interest on a covered loan, that may be more than a Civil Code unconscionability problem. It may also be a regulatory violation.
Truth in Lending: The Lender Must Disclose the Real Cost
Republic Act No. 3765, the Truth in Lending Act, requires disclosure of finance charges in credit transactions.
In practical terms, a borrower should not be left guessing:
- the amount financed;
- the total finance charge;
- the interest rate;
- other fees and charges;
- the total amount payable;
- the installment schedule;
- late payment charges;
- deductions from the loan proceeds.
This is especially important with online loans. Some apps advertise a low rate but deduct “processing fees” upfront, shorten the repayment period, and add penalties. The true effective cost may be much higher than the stated rate.
Example:
| Item | Amount |
|---|---|
| Approved loan | ₱10,000 |
| Processing fee deducted | ₱1,500 |
| Actual cash received | ₱8,500 |
| Amount due after 30 days | ₱12,000 |
Even if the lender says the interest is “only” ₱2,000, the borrower actually received ₱8,500 and must repay ₱12,000 after 30 days. That is why effective interest matters.
What Borrowers Can Do if They Are Being Charged 20% Monthly Interest
Step 1: Identify what kind of lender you are dealing with
Different rules apply depending on who lent the money.
| Lender Type | Practical Importance |
|---|---|
| Friend, relative, co-worker, informal lender | Civil Code rules apply; barangay conciliation may be needed if both parties are individuals in the same city or municipality |
| “5-6” lender | Often informal; interest may be challenged as unconscionable, but proof of payments is crucial |
| SEC-registered lending company | SEC rules, Truth in Lending, and Civil Code rules may apply |
| Financing company | SEC and financing company regulations may apply |
| Online lending app | SEC rules, data privacy rules, and unfair collection rules may apply |
| Bank or credit card issuer | BSP regulations and bank documents must be reviewed |
| Cooperative or microfinance entity | Special rules may apply depending on registration and regulator |
Search the lender’s business name, SEC registration, certificate of authority, app name, and collection agency name. Many abusive online lenders use multiple app names but only one registered company, or sometimes no valid authority at all.
Step 2: Gather all loan documents and proof
Before disputing the interest, organize your evidence.
Useful documents include:
- loan agreement or promissory note;
- disclosure statement;
- screenshots of the app loan screen;
- text messages, Viber, Messenger, WhatsApp, or email conversations;
- proof of cash received or bank/e-wallet transfer;
- payment receipts;
- GCash, Maya, bank, or remittance records;
- statement of account;
- collection letters;
- screenshots of threats, shaming, or messages to contacts;
- ID of collector, company name, and phone numbers used;
- barangay blotter, police blotter, or complaint records if harassment occurred.
If the loan was signed abroad, documents may need notarization, consular acknowledgment, or apostille depending on where they were executed and where they will be used.
Step 3: Compute the real interest and total charges
Do not rely on the lender’s total. Make a simple table.
| Date | Amount Received | Amount Paid | Interest Charged | Penalty/Fees | Balance Claimed |
|---|---|---|---|---|---|
| Jan. 1 | ₱20,000 | — | — | — | ₱20,000 |
| Feb. 1 | — | ₱4,000 | ₱4,000 | — | ₱20,000 |
| Mar. 1 | — | ₱4,000 | ₱4,000 | — | ₱20,000 |
| Apr. 1 | — | ₱4,000 | ₱4,000 | — | ₱20,000 |
In this example, the borrower has paid ₱12,000 but still owes the full ₱20,000 because payments were applied only to 20% monthly interest. This is a common pattern in debt traps. If the rate is later reduced or voided, the borrower may argue that excessive interest payments should be credited to the principal.
Step 4: Send a written request for recomputation
A borrower may send a calm written request asking for:
- copy of the loan agreement;
- Truth in Lending disclosure statement;
- full statement of account;
- breakdown of principal, interest, penalties, and fees;
- basis for the 20% monthly interest;
- recomputation using a lawful or reasonable rate;
- application of excess payments to principal.
Keep proof that the request was sent.
For individual lenders, this may help settlement. For companies, this creates a record in case of an SEC, BSP, NPC, or court proceeding.
Step 5: Raise the issue properly if a case is filed
If the lender files a collection case, the borrower must respond on time.
Under the Rules on Expedited Procedures in the First Level Courts, small claims cases include claims for payment or reimbursement of money where the value of the claim does not exceed ₱1,000,000, exclusive of interest and costs.
For small claims:
- the case is filed in the MeTC, MTCC, MTC, or MCTC;
- the defendant must file a verified Response within a non-extendible period of 10 calendar days from receipt of summons;
- evidence should be attached to the Response;
- lawyers generally cannot appear for parties at the small claims hearing, unless the lawyer is a party;
- the court process is designed to be faster than ordinary civil cases.
A borrower sued in small claims should not ignore the summons. The defense that interest is unconscionable must be clearly raised, with documents showing the amount received, amount paid, and how the 20% monthly rate was applied.
What Lenders Should Know Before Charging High Interest
Lenders also face risks when they charge 20% per month.
Even if the borrower signed the document, the lender may encounter these problems:
- the interest clause may be declared void;
- the court may reduce the collectible amount;
- excessive payments may be credited to principal;
- penalties and attorney’s fees may be reduced;
- collection practices may be investigated;
- an SEC-regulated lender may face administrative sanctions;
- threats or public shaming may lead to criminal, civil, regulatory, or data privacy complaints.
A written loan agreement should state:
- principal amount;
- release date;
- interest rate;
- whether interest is monthly or annual;
- due dates;
- penalties;
- whether interest compounds;
- security or collateral, if any;
- total amount payable;
- borrower’s acknowledgment of receipt.
But a well-written contract does not save an unconscionable rate. A 20% monthly interest clause is still risky.
Harassment, Threats, and Public Shaming Are Separate Issues
A borrower’s failure to pay does not give collectors the right to harass, threaten, shame, or contact unrelated people.
SEC Memorandum Circular No. 18, Series of 2019 prohibits unfair debt collection practices by financing companies, lending companies, and third-party collection service providers. Unfair practices include threats of violence or other criminal means, threats to take actions that cannot legally be taken, and abusive or unethical collection methods.
For online lending, common illegal or abusive practices include:
- posting the borrower’s face or ID online;
- sending “scammer” messages to the borrower’s contacts;
- threatening arrest for a purely civil debt;
- pretending to be from a court, police office, NBI, or prosecutor’s office;
- using insults, profanity, or sexualized language;
- repeatedly calling the borrower’s employer;
- disclosing the debt to people who are not guarantors;
- using fake demand letters or fake case numbers.
Nonpayment of an ordinary loan is generally a civil matter. It does not automatically mean the borrower can be arrested. However, separate criminal issues may arise if there is fraud, bouncing checks under B.P. Blg. 22, falsified documents, threats, coercion, unjust vexation, cyberlibel, identity theft, or data privacy violations.
Barangay, SEC, Court, Police, or NPC: Where Does the Problem Go?
| Problem | Possible Office or Process |
|---|---|
| Private loan dispute between individuals in the same city/municipality | Barangay conciliation may be required before court |
| Collection of unpaid principal or loan balance up to ₱1,000,000 | Small claims court |
| Larger civil collection case or complex issues | Regular court procedure |
| SEC-registered lending or financing company charging excessive covered rates | Securities and Exchange Commission |
| Online lending harassment or abusive collection | SEC, National Privacy Commission, police/NBI depending on facts |
| Unauthorized use of contacts or personal data | National Privacy Commission |
| Threats of violence, coercion, extortion, fake police/court threats | PNP, NBI, prosecutor’s office |
| Bank-related complaint | Bank’s internal complaint unit, then BSP consumer assistance mechanisms |
Barangay conciliation under the Local Government Code usually matters when both parties are natural persons living in the same city or municipality. It generally does not apply in the same way to corporations, banks, or many online lending companies.
Special Notes for OFWs and Foreigners
A Filipino abroad or a foreigner dealing with a Philippine loan should pay attention to documentation.
If a borrower or lender is outside the Philippines:
- a Special Power of Attorney for a Philippine representative may be needed;
- documents signed abroad may need apostille or consular acknowledgment;
- screenshots and electronic messages should be preserved with dates, phone numbers, email addresses, and account names;
- remittance records are important proof of payment;
- if a party must appear in a court process, check whether appearance through an authorized representative is allowed for that specific procedure.
Foreigners should also distinguish between lending money occasionally and operating a lending business in the Philippines. A person or entity regularly engaged in lending may need proper registration and authority. Foreign ownership, corporate structuring, taxation, and licensing issues may arise if the activity is a business and not merely a private transaction.
Common Scenarios
“I borrowed ₱10,000 and paid ₱2,000 every month, but the lender says I still owe ₱10,000.”
This is common with 20% monthly interest. The lender treats all payments as interest. If the rate is unconscionable or not in writing, the borrower may argue that some or all payments should be credited to principal.
“The lender says I agreed, so I have no right to complain.”
Agreement matters, but it is not absolute. Under the Civil Code and Supreme Court rulings, courts may refuse to enforce oppressive interest even if written and signed.
“The loan app gave me only ₱3,500 but wants ₱6,000 after seven days.”
The issue may involve more than nominal interest. The effective interest rate, processing fees, service fees, and penalties should be computed. If the lender is an SEC-regulated lending or financing company and the loan is covered by rate-cap rules, this may be reportable.
“The collector says I will be arrested tomorrow.”
Ordinary nonpayment of debt does not automatically result in arrest. Court cases require proper process. Threatening arrest to collect a civil loan may be an unfair collection practice, and depending on the words used, may raise other legal issues.
“The lender posted my name and photo online.”
That is a separate and serious issue. Public shaming may involve unfair debt collection, data privacy violations, cyber-related offenses, or civil liability, depending on the facts.
Documents to Prepare Before Disputing 20% Monthly Interest
| Document | Why It Matters |
|---|---|
| Loan agreement or promissory note | Shows whether interest was written and what rate was stated |
| Proof of amount released | Establishes the true principal received |
| Disclosure statement | Important for lending/financing companies and Truth in Lending compliance |
| Receipts and transfer records | Proves payments already made |
| Statement of account | Shows how the lender applied payments |
| Screenshots of app terms | Useful when app terms differ from later collection claims |
| Collection messages | Evidence of harassment, threats, or unfair practices |
| IDs and company details | Helps identify the proper respondent |
| Barangay records or police blotter | Supports timeline and harassment claims |
| SPA, apostille, or consular documents | Needed when a party is abroad and acting through a representative |
Frequently Asked Questions
Is 20% monthly interest usury in the Philippines?
In the strict old sense, not automatically, because the general Usury Law ceilings were suspended by Central Bank Circular No. 905. But 20% monthly interest may still be invalid, reduced, or deleted if a court finds it unconscionable. For covered lending or financing company loans, it may also violate SEC/BSP rate ceilings.
Can a lender legally charge 20% interest per month if I signed a promissory note?
Signing helps prove the agreement, but it does not guarantee enforcement. Philippine courts can reduce or strike down interest that is excessive, iniquitous, unconscionable, or contrary to morals. The borrower will usually still owe the principal.
What if the 20% monthly interest was only verbally agreed?
Under Article 1956 of the Civil Code, no interest is due unless expressly stipulated in writing. If there is no written proof of interest, the lender may be unable to collect the 20% monthly interest, although the principal may still be collectible.
Can I recover interest I already paid?
Depending on the facts, you may argue that excessive or invalid interest payments should be applied to the principal or considered in recomputing the balance. Recovery is fact-specific and depends on proof of payment, the agreement, and the forum handling the dispute.
Can an online lending app charge 20% monthly interest?
If the online lending app is operated by a covered lending company or financing company, SEC/BSP ceilings may apply to certain small, unsecured, general-purpose loans. A 20% monthly charge may exceed those ceilings. Even outside those rules, the charge may still be challenged as unconscionable.
Can I be jailed for not paying a loan with 20% monthly interest?
Nonpayment of an ordinary loan is generally a civil matter. You are not automatically jailed for failing to pay a debt. However, separate criminal issues may arise if there was fraud, falsification, bouncing checks, threats, or other criminal acts.
What should I do if the collector is threatening my family or employer?
Save screenshots, call logs, recordings where lawful, and names or numbers used. If the lender is a financing or lending company, the conduct may violate SEC rules on unfair debt collection. If personal data was misused, the National Privacy Commission may be involved. If there are threats of violence or extortion, police or NBI assistance may be appropriate.
Does notarization make 20% monthly interest valid?
Notarization helps prove that a document was executed, but it does not make an unconscionable interest rate automatically enforceable. A notarized loan agreement can still be reviewed by a court.
If the interest is void, do I still need to pay the principal?
Usually, yes. The invalidity or reduction of excessive interest does not normally erase the borrower’s obligation to return the amount actually received.
Can a small claims court reduce 20% monthly interest?
Yes, a borrower may raise unconscionable interest as a defense in a small claims case. The defense and supporting documents should be included in the verified Response filed within the required period after receiving summons.
