Frequently Asked Questions

How is FD maturity amount calculated?

Fixed deposit maturity is calculated using compound interest on your principal at the offered interest rate over the chosen tenure, usually compounded quarterly by most banks.

What is the difference between simple and compound interest on an FD?

Simple interest is paid only on the principal, while compound interest is paid on the principal plus accumulated interest, which gives a higher maturity amount over time.

Is FD interest taxable?

Interest earned on fixed deposits is generally taxable as income. Banks may deduct tax at source above certain limits, so consider this when comparing returns.
