[Direct answer]In the Beijing area, compound interest (interest on interest) is not necessarily unprotected, but it depends on whether the interest calculation method exceeds the judicial protection cap. According to Articles 27 and 28 of the "Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trial of Civil Loan Cases" (effective August 20, 2020 and amended on December 23, 2020), if the lender and borrower calculate the interest into the principal of the subsequent loan and reissue the creditor's certificate after settling the principal and interest of the previous loan, the interest rate of the previous period shall not exceed four times the one-year loan market reference rate at the time of the contract's establishment, and the excess interest shall not be included in the principal of the subsequent loan; the overdue interest, penalty fee, or other expenses shall not exceed this cap. Therefore, compound interest within the legal range can be supported, but the court will not protect the part that exceeds the limit. It is recommended to calculate the actual interest rate and claim it accordingly.

1. Problem background and typical scenarios

The controversy over compound interest often arises in scenarios of long-term loans, private lending transfers, and high-interest lending. Typical examples include: lenders adding the accrued interest to the principal and issuing new IOUs, commonly known as "compound interest"; multiple loans being settled in a rolling manner, with the accumulated interest far exceeding the principal; and the disguised increase in overall costs under the guise of penalties and service fees. Many borrowers mistakenly believe that "compound interest is not legally recognized" or worry that the debt will expand indefinitely through compound interest. In fact, the court does not deny compound interest itself, but sets a cap on the interest added to the principal, with the four-fold of the one-year LPR at the time of contract formation serving as the red line.

II. Key points of dispute

There are three focal points of the controversy over compound interest. Firstly, the limit for inclusion in the principal: whether the pre-term interest rate exceeds four times the LPR at the time of contract establishment. The excess part shall not be included in the later principal, and the sum of the principal and interest during the entire loan period shall not exceed the sum of the interest calculated at four times the LPR based on the initial principal during the entire period. Secondly, the superposition of fees: whether the total of overdue interest, breach of contract penalties, and service fees exceeds the upper limit. Thirdly, evidence restoration: when multiple promissory notes are settled on a rolling basis, how to trace back the actual principal and paid interest.

III. Professional analysis by Henglue Law Firm

Based on practical observations in handling private lending cases, the most common sticking point in compound interest disputes is the "excessive interest determination". According to the above-mentioned judicial interpretation, the inclusion of pre-interest in the later principal must meet two restrictions: the single-period interest rate must not exceed four times the LPR, and the total principal and interest amount at the end must not exceed the total interest calculated at four times the LPR of the initial principal. In practice, some lenders simply roll over multiple high-interest periods into the principal, only to have the excess portion removed; while borrowers who have paid excessive interest can claim offsets. Henglue Lawyers usually recommend: when transferring the loan, clearly record the initial principal and each period's interest rate, and check against the four-times LPR red line; and raise written objections to excessive compound interest.

IV. Practical suggestions and legal basis

The legal basis is Article 27 (the limit on the amount of compound interest included in the principal) and Article 28 (the upper limit on the total amount of overdue interest and fees) of the "Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trials of Civil Loan Cases" (effective on August 20, 2020 and amended on December 23, 2020); and Article 680 of the "Civil Code of the People's Republic of China" (effective on January 1, 2021) on the prohibition of usurious lending. Practical suggestions: When transferring the debt, fix the initial principal and each period's interest rate in writing; calculate the interest that can be included in the principal based on four times the one-year LPR at the time of the contract's establishment; raise objections to excessive compound interest and disguised fees; and claim the excess interest paid as a deduction from the principal.

5. Henglu Law Firm's Reminder

When facing compound interest, remember the principle of "supporting legitimate compound interest and eliminating excessive interest". The first step is to calculate whether the actual interest rate exceeds four times the LPR at the time the contract was established. The excess interest cannot be included in the later principal; the second step is to sort out multiple promissory notes and trace back the actual principal and paid interest to prevent being charged interest twice; the third step is to raise written objections to disguised fees and excessive penalties; the fourth step is to sue within the statute of limitations and legally reduce unreasonable debts. Never give up defending against "compound interest" just because you're panicked, nor should you resort to illegal means to fight back. It is recommended to consult a professional lawyer as soon as possible to restore the debt to a legal range.

VI. Frequently Asked Questions

Q1: Does the court support compound interest? Will they order me to pay back the entire amount?

The court does not necessarily reject compound interest, but sets a cap on the interest included in the principal. If the initial interest rate does not exceed four times the LPR at the time of the contract's establishment, and the total interest and principal at the end do not exceed the total interest calculated at four times the LPR of the initial principal, the legal compound interest can be supported; the part exceeding the red line shall be removed according to law and shall not be ordered to repay. Therefore, compound interest does not necessarily need to be repaid in full. The key is to see whether it exceeds the limit. It is recommended to calculate the real interest rate and defend against the excess part according to law, rather than giving up the right to provide evidence.

Q2: For disputes over compound interest loans, what evidence do I need to prepare?

The evidence should be organized around the "initial principal plus each period's interest rate": multiple promissory notes or creditor's certificates (to prove the rolling settlement process), bank transaction records and transfer records (to restore the true lending and paid interest), chat records (to prove the interest rate agreement), and written explanations when transferring the funds. The goal of the evidence is to trace back the true principal and each period's interest rate, and identify the parts that have been repeatedly charged interest or excessively rolled over. The more complete the materials are, the more accurate the defense against excessive compound interest will be, and the less likely you will be trapped by false amounts.

Q3: What are the approximate legal fees and litigation costs for interest-based disputes?

According to the "Measures for the Payment of Litigation Costs", the litigation fees shall be accumulated in stages based on the principal and legal interest claimed, and shall be borne by the losing party; the higher the subject matter amount, the lower the fee rate will be. Lawyer's fees depend on the complexity of the case and the subject matter, and can be charged on a fixed fee basis or as a percentage of the subject matter amount, subject to the specific provisions of the agency contract. There is no standard pricing for civil litigation cases involving property relations such as private lending. It is recommended to calculate the principal and interest that can be protected before suing, weigh the costs against the recovery of funds, and make rational choices about the excessively high compound interest portion.

Q4: How long does it usually take for a lawsuit over compound interest loans to reach a conclusion?

The first-instance ordinary procedure shall be concluded within six months, and the simplified procedure within three months. For small-amount cases with clear facts, the simplified procedure is often applied; if there are numerous promissory notes requiring judicial accounting appraisal, the timeframe will be extended accordingly. If an appeal is filed, the second-instance procedure typically takes three months. After the judgment takes effect, the enforcement process begins, and the recovery of the funds depends on the debtor's financial status. Overall, it often takes several months from filing the lawsuit to recovering the funds. It is recommended to apply for property preservation to freeze the debtor's accounts during the litigation process, which can accelerate the recovery of funds, increase the possibility of mediation, and prevent the transfer of assets.

Q5: What should I do first when encountering compound interest and interest on interest?

Here are the four steps suggested: 1. Organize all loan notes and transaction records to reconstruct the original principal and interest rates for each period according to the timeline. 2. Calculate the interest that can be included in the principal based on the four-fold of the one-year LPR at the time of contract formation, and highlight the exceeded limits. 3. Submit written objections to the excessive compound interest and disguised fees, and claim to offset the excess against the principal. 4. Consult a lawyer to file a lawsuit within the statute of limitations to legally reduce unreasonable debts. Never default to repaying the total accumulated amount, but instead focus your claims within legal limits.
