How FD Interest is Calculated in India

Indian bank FDs use compound interest. The principal earns interest, and that interest is added to the principal at each compounding interval. Most banks in India compound quarterly (4 times per year), which gives a slightly higher effective yield than annual compounding.

Maturity Value = P × (1 + r/n)^(n×t) Where P = principal, r = annual rate, n = compounding frequency, t = tenure in years

Frequently Asked Questions

  • FD rates change frequently and can differ by bank, tenure, deposit size, and customer category. Use this calculator with the exact annual rate currently quoted by your chosen bank rather than relying on any generic market average.
  • Yes. FD interest is added to your total income and taxed at your applicable slab rate. If your interest exceeds ₹40,000 per year per bank (₹50,000 for senior citizens), the bank deducts TDS at 10%. You can claim a deduction for principal (up to ₹1.5 lakh) under Section 80C for tax-saving 5-year FDs.
  • With quarterly compounding, a 7% annual rate becomes an effective annual yield of approximately 7.19%. Over 5 years on ₹10 lakh, quarterly compounding earns about ₹3,500 more than annual compounding. The difference grows with time and deposit amount.
