Finding a different car loan interest rate than expected can increase your monthly equated monthly instalment and total repayment cost. Whether you are reviewing a new agreement or checking an existing loan, the first step is to confirm what your signed documents actually say. This guide explains how to check your car loan agreement and what to do if the rate appears incorrect.
Check your loan sanction letter and agreement
Your sanction letter is usually the first document that states the approved interest rate. Compare it with the final loan agreement before signing. Look for the annual percentage rate, whether it is fixed or floating, and the effective date of the rate.
If you have already signed the agreement, locate the section titled “Rate of Interest” or “Interest Charges.” Check whether the rate matches what was quoted during the application. Some agreements mention a base rate plus a spread, while others state a single rate.
Understand fixed and floating rates
A fixed rate remains unchanged for the agreed tenure, unless the agreement allows revision under specific conditions. A floating rate can change when the lender’s benchmark or external reference rate changes. If your loan has a floating rate, an unexpected change may be permitted under the agreement.
Review the reset clause, if any. It should explain when the rate can be revised, how you will be notified, and whether your tenure or EMI will change.
Review the amortisation schedule
The amortisation schedule shows how each EMI is split between principal and interest. If the interest rate has changed, the interest portion of future EMIs may be higher or lower. Compare the original schedule with the latest statement to identify discrepancies.
Also check the total interest payable over the loan tenure. A small change in the annual rate can result in a significant difference in the total amount repayable.
Documents to keep ready
- Signed car loan agreement
- Loan sanction letter
- Most recent loan statement
- Amortisation schedule
- Email or SMS communication about the rate change
- Identity proof and loan account number
Steps to take if the rate seems wrong
- Compare the quoted rate with the rate in the signed agreement.
- Check whether the change is due to a floating rate revision or processing fee adjustment.
- Contact your lender’s customer service and request a written explanation.
- Ask for a revised amortisation schedule showing the new EMI and total interest.
- If the response is unsatisfactory, escalate the matter to the lender’s grievance redressal officer.
- Maintain records of all communication, including dates and reference numbers.
Possible costs and outcomes
Correcting an administrative error may not involve a charge. However, if you request changes to the loan structure, such as switching from floating to fixed interest, the lender may levy conversion or processing charges. These vary by lender and should be confirmed before proceeding.
If the rate change is legally permitted under your agreement, you may choose to continue with the loan, make part-prepayments to reduce interest cost, or explore refinancing with another lender. Refinancing may involve foreclosure charges on the existing loan and processing fees on the new loan.
