Fixed Deposit Calculator formula
The formula is shown so you can understand the relationship between the inputs instead of treating the result as a black box.
Worked example
A ₹1,00,000 cumulative FD at 8% for one year with quarterly compounding matures at about ₹1,08,243.
Your own result may differ because it uses the exact values you enter. For comparisons, keep the method and units consistent from one calculation to the next.
Important assumptions and limitations
Estimate only. It assumes a cumulative deposit, a fixed rate for the full period and the selected compounding frequency.
Calculator outputs are estimates unless the underlying arithmetic is exact by definition. For decisions involving tax filing, lending, health, contracts or institutional grading rules, use the calculator as a first check and confirm the final decision with the relevant authoritative source.
