Finding the Hidden Interest Rate
Many lenders quote flat rates, processing fees, or EMI amounts without clearly disclosing the effective annual rate. This calculator uses iterative numerical methods to back-calculate the exact reducing-balance interest rate from your actual EMI, so you can compare apples-to-apples across lenders.
Example: A car dealer offers โน10L at "8% flat" for 5 years. EMI = โน18,333. The effective reducing-balance rate is actually 14.8% โ nearly double the quoted flat rate.
