Frequently asked questions

How is FD interest calculated in India?

Most Indian banks compound FD interest quarterly. Maturity = P × (1 + r/n)^(n×t), where P is deposit, r is annual rate, n is compounding periods per year and t is tenure in years.

Is FD interest taxable in India?

Yes. FD interest is added to your income and taxed per your slab. Banks may deduct TDS if interest exceeds ₹40,000 per year (₹50,000 for senior citizens).

What is effective annual yield on an FD?

Effective yield reflects compounding — the actual annual return you earn when interest is reinvested each period, which is higher than the nominal rate when compounded more than once a year.
