If you open an FD of ₹1,00,000 for 5 years at a 7% interest rate compounded quarterly, your maturity amount will be ₹1,41,478. The total interest earned is ₹41,478.
Compounding means you earn interest on interest already earned. Most Indian banks compound interest quarterly, which yields higher returns than simple interest.
Yes, FD interest is taxable based on your income tax slab. Banks deduct TDS (Tax Deducted at Source) if your annual interest exceeds ₹40,000 (₹50,000 for senior citizens).
