What is the FD Calculator?
A fixed deposit is generally easier to model than a market-linked investment because the rate is specified for the product period. However, actual maturity and tax treatment depend on the bank and product terms.
How the calculation works
This calculator uses a simplified quarterly-compounding model: maturity value = principal × (1 + annual rate ÷ 4)^(4 × years). Actual products can use different compounding or payout arrangements.
Worked example
For a ₹100,000 deposit at an assumed 7% annual rate for 5 years, the calculator applies quarterly compounding over 20 quarters. The displayed interest is the difference between the projected maturity amount and principal.
