An FD Calculator is an online tool that helps you estimate the maturity amount and total interest earned on a Fixed Deposit. You enter the principal, interest rate, tenure, and compounding frequency, and the calculator does the math for you — no manual computation needed.
For compound interest FDs, the formula is: M = P × (1 + r/n)^(n×t), where P is the principal, r is the annual interest rate (decimal), n is the number of compounding periods per year, and t is the tenure in years. Simple interest FDs use: M = P + (P × r × t).
Higher compounding frequency (e.g. monthly vs yearly) means interest is calculated and added to the principal more often, resulting in slightly higher returns. Monthly compounding yields marginally more than quarterly, which yields more than yearly compounding, for the same stated annual rate.
An FD calculator lets you plan your investment by showing exactly how much your deposit will grow. You can compare different tenures, interest rates, and compounding frequencies side-by-side to find the best option before committing your money.
The minimum FD amount varies by bank. Most Indian banks require a minimum deposit of ₹1,000 to ₹5,000. Some premium or senior citizen FDs may have different thresholds. Check with your specific bank for their current requirements.
Yes, interest earned on FDs is taxable in India as per your income tax slab. Banks deduct TDS (Tax Deducted at Source) at 10% if the annual interest exceeds ₹40,000 (₹50,000 for senior citizens). You can submit Form 15G/15H to avoid TDS if your total income is below the taxable limit.
Most banks allow premature withdrawal of FDs, but a penalty is usually applied — typically 0.5% to 1% reduction in the applicable interest rate. Some banks offer special FDs with a lock-in period that do not permit early withdrawal. Always check the terms before investing.
In a cumulative FD, the interest is compounded and paid at maturity along with the principal — ideal for wealth accumulation. In a non-cumulative FD, interest is paid out at regular intervals (monthly, quarterly, etc.) — suitable for those needing regular income, such as retirees.
