In financial loan disputes, the quantification and judicial recognition of loss is a primary focus of court proceedings, and essential to a bank’s full recovery. The calculation is technical, complex and variable.
Owing to institutional disparities in accounting systems, interest accrual logic and write-off policies, a bank’s pre-litigation book loss often fails to align with the legally recognised loss, rendering the final sum difficult to pinpoint precisely at claim stage.
A bank’s claim aggregates four elements: principal; term interest; default penalty interest; and compound interest. But inconsistency between term and default interest rules, disputes over the appropriation hierarchy of payments, ill-defined contours on the imposition of penalty and compound interest, and differing rate caps for financial versus non-financial entities can all conspire to render a bank’s loss calculations defective, precluding full judicial recovery.
This two-part series deconstructs the legal framework, calculation rules, judicial limits and nuances of bank loss recovery, offering a roadmap for quantifying legitimate loss in litigation. Part one addresses calculation of principal and term interest.
Principal

The principal is a sum of money advanced to a borrower obliged to repay it with interest at maturity. The return of principal is statutorily protected, independent of any regulatory adjustments to interest rates.
The principal base is legally defined as the net sum actually advanced. Under article 670 of the Civil Code, interest shall not be deducted upfront from the principal. Any such pre-deduction obliges the borrower to repay and pay interest solely on the amount actually received.
Any attempt by a bank to disguise interest deductions as fees – whether for services, consultancy or guarantees – is unenforceable. Courts will invariably fix principal at the actual amount credited to the borrower.
In instalment repayments, the principal reduces incrementally per contract terms, either via equal monthly instalments (where interest is front-loaded) or fixed principal repayments (where instalment amount declines). The remaining unpaid balance serves as an ongoing basis for interest charges. When a borrower makes partial repayment, the statutory order of allocation under article 561 of the Civil Code applies. Barring any alternative agreement, repayment must first cover enforcement costs and then interest, with the remainder applied to the principal. A bank should not unilaterally decide to offset the full sum against the principal alone.
Calculation of interest further distinguishes between full and timely interest payments and equal interest instalments. “Full and timely” denotes punctual discharge of all interest per the loan agreement. Under “equal interest instalments” the sum of interest paid in each period remains constant.
For example, on a facility of RMB10 million (USD1.4 million) at annual interest rate of 6% over a one-year term with quarterly rests, standard full and timely payment yield interest of about RMB600,000. Where interest is paid in equal instalments, the amount due each quarter must be derived from the amortisation schedule, calculated on the remaining principal balance for that specific period.
In judicial practice, the principal sum claimed by a lender usually represents the aggregate outstanding balance after acceleration of the loan. For example, in the case of Agricultural Bank of China (a branch) v Li, handled by the author, the bank advanced a residential mortgage of RMB480,000. Following partial early repayments by the borrower, the bank’s repayment records and amortisation software asserted remaining principal balance of RMB183,999.63.
The court awarded this entire sum, underscoring that calculation of principal must be grounded in the initial disbursement amount, repayment records and the system ledger. To forestall any challenge regarding balance accuracy, lenders need to furnish a complete chain of documentary evidence in litigation.
Interest
Interest is a core contractual entitlement of the lender; the price paid for occupation of bank capital. Under article 680 of the Civil Code, a loan contract silent on the matter of interest is interest-free. Where terms are unclear, interest may be implied by reference to market practice or prevailing rates.
Notably, loans between individuals carry no entitlement to interest unless stipulated. For institutional loan contracts, the agreed interest rate governs. Since lending rates were fully deregulated in 2013, borrowers and lenders have been free to set their own terms, provided they comply with regulatory standards.
Interest calculation is strictly confined to the actual principal disbursed. Where repayment occurs in instalments, the principal is written-down each term accordingly, and any partial payments must be applied in the specific order mandated by law.
The interest period runs from the date of actual drawdown until contractual maturity date. The frequency of interest capitalisation may be contractually specified as monthly, quarterly or annually.
The central bank grants lenders the latitude to compute interest based on either a 360-day or 365-day year, as defined in the loan agreement. Absent such agreement, a 360-day year is applied. The applicable formulae are: Daily rate = annual rate ÷ 360; and Interest = principal × annual rate × days elapsed ÷ 360 (or interest = principal × actual days × daily rate).
The courts impose a boundary on the total financing burden. Licensed lenders are exempt from the private lending rate cap of four times the loan prime rate (LPR) on their base rate. However, once default interest, compound charges and fees are combined, overall annual rate is judicially limited to 24%.
Two further rules apply: the lender cannot deduct interest upfront from the drawdown amount, nor can it roll unpaid standard interest into the default penalty base once the loan is overdue.
In the Agricultural Bank v Li case, the contract specified an annual interest rate of 4.972%. With outstanding principal of RMB183,999.63, the bank’s system generated an unpaid interest figure of RMB2,577.27, which represented 101 days rolling accrual from the last due payment. Finding the computation in accordance with the loan terms, the court granted the claim in its entirety.
To substantiate such a claim, banks must provide a coherent ledger supported by the disbursement voucher, the original loan contract and a line-by-line breakdown of repayments received.

The second part of this series will dissect the mechanics of default interest, compounding of charges, statutory rate caps imposed by the courts and the precise boundaries of accrual.
