Audit interest and fees on an Indian credit-card statement
Use this five-step check for one statement from an Indian consumer credit card. It compares interest and non-late fees with the issuer's current MITC, Key Fact Statement and dated fee notices. It does not determine that a charge is legally owed or reproduce every issuer's billing system. Keep fraud disputes, late-payment-charge reviews and bill payment in their separate processes.
MISSION Check whether interest and non-late fees on one Indian consumer credit-card statement match the issuer's terms and disclosed calculation method.

Gather one redacted statement and the issuer terms effective for that billing cycle; classify interest and non-late fees; independently reproduce only charges that fit the issuer's disclosed method; ask the issuer for an itemized explanation of any mismatch; then reconcile the answer or follow the official grievance route while keeping a secure evidence record.

One step at a time.
Follow the order below. If a step names a Nirmion tool, its link is right there with it.
- 01
Choose one card and collect the right statement-era terms
Limit this guide to a personal consumer credit card issued in India; business or corporate cards can have different agreements. Select one complete billing cycle and download its statement from the issuer's official app or website. Also retrieve the Most Important Terms and Conditions (MITC), Key Fact Statement or welcome terms, and any dated notice that changed a rate or fee. Record the cycle dates and payment, refund or reversal posting dates. Terms in force for the charge date matter, so do not compare an old statement only with today's fee page. Keep the full statement and card details private; use a redacted working copy and never share a card number, CVV, PIN or OTP in a public document or with a calculator.
- 02
Separate interest and covered fees from other issues
Make a private line-item table for each interest amount and non-late fee you want to check, such as annual membership, cash-advance or foreign-transaction fees. For each line, copy the statement's transaction category, billed amount, charge date, relevant balance or transaction, and the matching APR, calculation example, fee amount and waiver condition from the applicable issuer terms. Separate taxes and credits so they are not mistaken for issuer fees. Exclude late-payment charges, suspected fraud/unauthorized transactions, payment-posting delays and unrelated subscriptions; use the dedicated issuer process for those. If you cannot identify the exact product version, fee notice or transaction category, ask the issuer for it instead of assuming another card's schedule applies.
- 03
Reproduce only the charges that fit the disclosed method
Compare the rate and method the issuer disclosed with the outstanding amount used in the statement. RBI directions say statements should prominently show the applicable APR and how the unpaid amount used for interest was determined; interest is to be levied on the outstanding amount adjusted for payments, refunds and reversed transactions. For a first-pass arithmetic check, use Nirmion's Credit Card Interest and Fee Audit with only the balance basis, APR, days, reported interest and fee amounts from your private working copy. The tool uses nominal APR divided by 365 and lets you enter an average-daily-balance or daily method; its fee table compares reported with expected fees that you enter. It cannot retrieve the issuer's account, infer missing transaction-level balances, apply every grace-period/compounding/promotion rule, or decide whether a charge is valid. Mark its differences as questions for the issuer, not proof of an error; if the disclosed method does not fit the inputs, skip the calculation.
- 04
Ask the issuer to explain each unexplained line
Submit a billing complaint through the card issuer's official channel, naming the billing cycle and the exact interest or non-late fee line. Ask for the transaction-level balance basis, rate, day count, payment/refund adjustments, fee schedule version and any waiver condition used. Attach only the minimum redacted evidence needed and keep the complaint acknowledgement or docket number. RBI's billing direction requires the card issuer to provide an explanation and, where applicable, documentary evidence within a maximum of 30 days after a bill complaint. Do not treat Nirmion's modeled difference as an issuer finding, and follow the issuer's official statement and due-date instructions while the question is being reviewed.
- 05
Reconcile the response and close or escalate the case
Compare the issuer's written explanation with your statement, the terms effective for that period and any payment, refund or reversal timestamps. If corrected, save the revised statement or adjustment confirmation; if explained, record the issuer's calculation and close the check. If the issuer rejects the complaint, gives an unsatisfactory reply, or does not respond within 30 days, the RBI FAQ says the cardholder may approach the RBI Ombudsman through its Complaint Management System. Preserve the issuer docket, dates and redacted evidence for that next step. Completion means you have a traceable issuer response or have deliberately taken the unresolved case to the stated escalation channel; a calculator result alone is not resolution.
