The annual percentage rate, or APR, on a personal loan expresses the annual cost of borrowing including interest and other associated charges. It can therefore be higher than the advertised interest rate. Under RBI's Key Facts Statement rules for covered retail term loans, the lender must show APR and a repayment schedule before the borrower signs the contract.
The first comparison to make is between what the loan costs on paper and what actually reaches the borrower. A fee deducted upfront reduces the money available to use, even when interest is calculated on the full sanctioned amount. Two offers with the same stated interest rate can consequently have different APRs.

What is APR in a personal loan?
The RBI circular dated 15 April 2024 defines APR as the annual cost of credit, including interest and other charges associated with the facility. Its harmonised KFS rules cover retail and MSME term loan products of the regulated entities addressed by the circular. New covered loans sanctioned from 1 October 2024 must comply, including fresh loans to existing customers.
A processing charge is one reason APR can exceed the interest rate. RBI also says actual third-party charges recovered through the lender, such as insurance or legal charges, form part of APR and must be disclosed separately. The lender must provide receipts and related documents for each such payment within a reasonable time.
That does not mean every possible future event can be represented by a single headline number. Read the individual fee disclosures and contractual conditions as well. An APR is useful only alongside the amount borrowed, payment dates, term and charges on which it was calculated.
How to calculate APR with an upfront fee
Consider a deliberately simple hypothetical loan: Rs 1,00,000 is sanctioned for exactly one year, the quoted annual interest is 10%, and Rs 2,000 is deducted as an upfront fee. Assume there are no other charges and a single repayment at the end of the year. This is a teaching example, not an offer or a statement of any lender's current rates.
The borrower receives Rs 98,000. Interest on the sanctioned principal is Rs 1,00,000 × 10% × 1 year = Rs 10,000. The agreed end-of-year repayment is therefore Rs 1,10,000. For this single-payment, exactly-one-year example, annual borrowing cost = (repayment ÷ net amount received) - 1.
Substituting the amounts gives (Rs 1,10,000 ÷ Rs 98,000) - 1 = 0.12244898, or about 12.24%. The difference from 10% arises because the borrower has the use of Rs 98,000 while the repayment includes interest calculated on Rs 1,00,000. Simply adding two percentage points to the interest rate would not reproduce that result.
An instalment loan needs a different calculation because money is repaid on several dates. The cash-flow equation is: net disbursal = the sum of each scheduled repayment discounted back to the disbursal date. For equal monthly periods, this can be written as D = Σ[P_t ÷ (1 + i)^t], where D is net disbursal, P_t is the payment in month t and i is the monthly discount rate. The lender's APR computation sheet should show its annualised result and assumptions.
For the interest and principal split within repayments, our EMI formula and worked loan example explains the underlying schedule. Our flat versus reducing interest calculation covers another reason apparently similar rate labels can describe different costs.
What must the Key Facts Statement show?
The KFS must be written in a language the borrower understands. The lender must explain it and obtain an acknowledgement of understanding. It must carry a unique proposal number, an APR computation sheet and an amortisation schedule covering the loan term. The KFS must also appear as a summary box within the loan agreement.
There is a decision window as well. For loans with a term of seven days or more, the KFS must remain valid for at least three working days. For terms shorter than seven days, the minimum is one working day. Within that validity period, the lender is bound by the stated terms if the borrower accepts them.
RBI further says a charge omitted from the KFS cannot be imposed at any stage of the loan without the borrower's explicit consent. If an amount on the sanction letter, deduction statement or payment schedule does not match the KFS, ask the lender to identify the charge and its contractual basis before treating the figures as comparable.
Does this KFS rule cover credit card bills?
Credit card receivables are expressly exempted from this particular circular. Do not apply its personal loan disclosure framework to a card balance without checking the separate card rules. Our credit card minimum due explainer addresses the different question of why interest may continue after a minimum payment.
A useful final check is to place four amounts together: sanctioned principal, net disbursal, total scheduled repayments and separately disclosed charges. Those numbers explain why an APR differs from the headline interest rate. They also reveal whether two quotations have been calculated using comparable payment timing and costs.
