What is Flat vs Reducing Rate?

This calculator compares two common loan interest structures: flat rate and reducing (diminishing) rate. It helps you see the real cost difference, as flat rates can appear lower but often result in higher total interest.

How the Calculator Works

For the same loan amount, tenure, and similar quoted rates, the calculator computes the EMI and total interest for both flat and reducing rate methods, so you can compare the true cost.

Formulas

Flat Interest = Loan × (Flat Rate / 100) × Years

Flat Rate EMI = (Loan + Flat Interest) / (Years × 12)

Flat Rate should be entered as annual percent (e.g., 10 for 10%).

Reducing Rate EMI = Loan × r × (1 + r)n / ((1 + r)n − 1)

Important: If r = 0 (zero interest), Reducing EMI = Loan / n
