What is FD Calculator?
FD Calculator (Fixed Deposit Calculator) helps you estimate the maturity value of a fixed deposit with any bank. Enter the principal, annual interest rate, and tenure in years and months. Choose whether interest is paid at maturity (cumulative FD), quarterly, or monthly to match your bank's offering.
The calculator applies the standard Indian bank FD formula of quarterly compounding for cumulative deposits, and simple interest for periodic payout options. Senior citizens can toggle a +0.50% rate benefit, which most banks offer. If your estimated annual interest exceeds the TDS threshold (₹40,000 for regular depositors, ₹50,000 for senior citizens), the calculator displays a TDS advisory with information on Form 15G/15H.

FAQ
How is FD interest calculated in India?
For cumulative FDs (interest paid at maturity), banks in India typically compound interest quarterly. The formula is: A = P × (1 + r/400)^(4n), where r is the annual rate and n is the tenure in years. For non-cumulative FDs (quarterly or monthly payout), simple interest is applied on the principal for each period.
What is TDS on FD interest?
Banks deduct TDS (Tax Deducted at Source) at 10% if the total FD interest credited in a financial year exceeds ₹40,000 (₹50,000 for senior citizens). The deducted TDS is reflected in your Form 26AS and can be claimed as a credit when filing your income tax return.
How can I avoid TDS on FD?
If your total income is below the taxable limit, you can submit Form 15G (for individuals below 60 years) or Form 15H (for senior citizens) to your bank at the start of each financial year. This instructs the bank not to deduct TDS. You must still declare the interest income when filing your return.
What is the senior citizen FD rate benefit?
Most banks in India offer senior citizens (aged 60 and above) an additional 0.25% to 0.75% interest over the regular FD rate. The calculator uses 0.50% as a standard assumption. Check your specific bank's offer for the exact benefit.
What is the difference between cumulative and non-cumulative FD?
A cumulative FD reinvests interest and pays the full maturity amount (principal + compounded interest) at the end of the tenure. A non-cumulative FD pays interest periodically (monthly, quarterly, or annually) and returns only the principal at maturity. Cumulative FDs earn more due to compounding but are better for wealth building; non-cumulative FDs suit those who need regular income.
