Example calculation
Depositing ₹5,00,000 at 7% for 5 years with quarterly compounding gives an estimated maturity of ₹7,07,389, including ₹2,07,389 of interest.
How to use this calculator
- Principal amount — the sum you will deposit on day one.
- Annual interest rate — the card rate your bank quotes for that tenure and depositor category (senior-citizen rates are usually higher).
- Tenure — in years; use fractions for odd periods such as 18 months (1.5).
- Compounding frequency — most Indian banks compound quarterly; choose what your deposit advice states. The maturity value, interest earned and year-by-year table update instantly.
What changes the result most
Tenure and rate dominate; compounding frequency is a smaller adjustment. On ₹5 lakh at 7% for three years, moving from annual to quarterly compounding adds about ₹3,200, whereas one extra year at the same rate adds roughly ₹44,000. A 1-year FD renewed five times versus a single 5-year FD is a bet on rate direction: the five-year deposit locks today's rate, which helps if rates fall and hurts if they rise. Treat the inputs as a scenario and re-run with the rates your bank actually offers for each tenure.
FD formula
A cumulative fixed deposit uses compound interest:
M = P × (1 + r/n)n×t
where P is the principal, r is the annual rate (as a decimal), n is the number of compounding periods per year, and t is the term in years.
Worked example: ₹5 lakh at 7% — cumulative vs payout
Place ₹5 lakh in a 3-year FD at an assumed 7% with quarterly compounding. Left to accumulate, it matures at about ₹6,15,720 — interest of ₹1,15,720. Choose a quarterly payout instead and the bank pays simple interest of ₹8,750 every quarter: 12 payouts total ₹1,05,000, about ₹10,700 less, because nothing is reinvested. That gap is the price of regular income. The same ₹5 lakh split as ₹13,900 a month into a recurring deposit over three years would earn noticeably less again, since later instalments compound for less time. See cumulative vs non-cumulative FD for when each suits.
A common mistake: comparing the maturity figure to a pre-tax SIP projection
The maturity value here is pre-tax, and FD interest is taxable at your slab with TDS deducted above a threshold (see how FD and RD interest is taxed). For a depositor in the 30% bracket, a 7% FD delivers roughly 4.9% after tax — before inflation. Compare after-tax numbers, and use the Compound Interest calculator to see how the same principal behaves at other compounding frequencies.
Assumptions & what this calculator does not include
- •Models a cumulative FD where interest is reinvested until maturity.
- •TDS and taxation are not applied to the maturity value shown.
- •Premature-withdrawal penalties are not modelled.
- •Actual bank calculation conventions may differ slightly.
