FD Calculator
Estimate what a fixed deposit will be worth at maturity from the deposit amount, interest rate and duration — with the compounding frequency your bank uses.
This is an illustrative estimate. It applies the standard compound-interest formula at the rate you enter — your bank's actual payout can differ due to its exact day-count rules, TDS deducted on interest, and premature-withdrawal penalties. Confirm the maturity amount with your bank; this is not financial advice. Amounts work in any currency.
How to calculate FD maturity value
- Enter the amount you’re depositing.
- Enter the annual interest rate your bank offers.
- Enter the duration and pick the compounding frequency (quarterly for most Indian banks).
- Read the maturity value and interest earned below.
Frequently asked questions
What formula does this use?
Standard compound interest: A = P × (1 + r/(100 × n))^(n × t), where P is the deposit, r the annual rate, n compounding periods per year, and t years.
Why quarterly compounding by default?
Most Indian banks compound fixed deposit interest quarterly. If your bank states a different frequency, pick it from the dropdown — the difference matters over long durations.
Does this account for TDS or tax?
No — it shows gross maturity value. Interest on FDs is taxable, and banks deduct TDS above a threshold. Your post-tax return depends on your tax situation.
