Flat vs Reducing: How They Differ

Flat Rate Method

Interest = Principal × Rate × Years (calculated on FULL principal, even after partial repayment)

You pay interest on ₹10L for ALL 5 years, even though by year 3 you've already repaid ₹6L!

Reducing Balance Method

Interest each month = Outstanding Balance × Monthly Rate

Interest reduces every month as you pay back principal. Fair and transparent.

Rule of Thumb

Flat Rate × 1.8 ≈ Equivalent Reducing Rate

  • Flat 7% ≈ Reducing 12.6%
  • Flat 10% ≈ Reducing 18%
  • Flat 12% ≈ Reducing 21.6%

Always ask: "Is this flat or reducing?" before signing any loan.
