FD Calculator
Work out the maturity value of your fixed deposit.
A fixed deposit (FD) pays a fixed interest rate for a fixed time. Most Indian banks compound FD interest quarterly.
Formula used
Maturity = P × (1 + r/q)^(q × t), where q is the number of compounding periods a year.
Things to remember
- FD interest is taxed at your slab rate every year.
- Banks deduct TDS once interest crosses a yearly limit.
- Senior citizens usually get an extra 0.25–0.50% rate.
