FD Interest Calculator

What is a Fixed Deposit (FD)?

A Fixed Deposit (FD) is a savings product offered by banks and many NBFCs in India where you deposit a lump sum for a fixed tenure at a fixed rate of interest. Unlike a savings account, you typically cannot withdraw the amount before maturity without paying a penalty (or you get a lower interest rate). In return, FDs usually offer higher interest than savings accounts. Tenures range from a few days to 10 years; rates vary by bank, tenure, and whether you are a senior citizen (seniors often get 0.25–0.50% extra). FDs are popular for short- to medium-term goals and for parking emergency funds safely.

FD interest is taxable; TDS may apply if interest in a year exceeds ₹40,000 (₹50,000 for senior citizens). You can submit Form 15H/15G if your total income is below the taxable limit. Use an FD interest calculator to see the maturity amount and interest before you invest, and to compare offers from different banks or tenures.

How is FD interest calculated in India?

Most banks in India use quarterly compounding for FD interest. The maturity amount is: Principal × (1 + r/4)^(n×4), where r is the annual rate as a decimal (e.g. 0.07 for 7%) and n is the tenure in years. So for each year, interest is applied four times (every quarter). Some banks offer monthly compounding or payout options; the calculator can account for different frequencies. TDS may apply on the interest; senior citizens often get a higher rate. The calculator above shows the maturity value and total interest so you can plan and compare.

Example: ₹10 Lakh, 7%, 5 years

For a fixed deposit of ₹10,00,000 (₹10 lakh) at 7% per annum for 5 years with quarterly compounding, the maturity amount works out to approximately ₹14.1 lakh. The interest earned is about ₹4.1 lakh. So your money grows by over 40% in five years. Senior citizens often get 7.25–7.5% for the same tenure, which would yield a higher maturity. Use the calculator above with your principal, the rate your bank offers, and the tenure to get exact figures. Remember that interest is taxable, so your post-tax return will be lower if you are in a tax slab.

Benefits of Using This Calculator

An FD interest calculator helps you see the exact maturity amount and interest for a fixed deposit at a given rate and tenure, so you can compare offers from different banks and choose the right tenure before you invest. It shows how quarterly (or other) compounding affects the result—important when comparing with products that compound monthly or yearly. Use it to plan short- and medium-term savings goals and to estimate how much interest you will earn so you can plan for TDS and post-tax returns.

You can try different tenures (e.g. 1 year vs 3 years) to see how locking in for longer often gives a higher rate and more interest. The calculator is free and requires no sign-up; use it as often as you need to compare scenarios.

How to Use This Calculator

Enter the FD principal in rupees (the amount you want to deposit), the annual interest rate offered by the bank (e.g. 6.5 or 7.25), and the tenure (in years or months). If the tool supports it, select the compounding frequency—most Indian FDs use quarterly. The calculator will show the maturity value and the total interest earned.

Change any input to compare different banks or tenures. Remember that FD interest is taxable; TDS may be deducted if interest exceeds the threshold. Use the result to plan for post-tax returns and to decide how much to invest and for how long. Senior citizens can often get a higher rate—enter that rate to see the difference.
