FD Calculator
FD maturity value with quarterly, monthly or cumulative compounding, plus post-tax yield.
Inputs
Formula
- M = P × (1 + r/n)^(n × t)
- Interest = M − P
- Effective yield = (1 + r/n)ⁿ − 1
- Post-tax interest = Interest × (1 − slab%)
Indian banks compound cumulative FDs quarterly, so the maturity value exceeds simple interest by a widening margin as tenure grows. Interest is taxable at your slab on an accrual basis each year, and TDS applies above the threshold, so the post-tax yield — not the headline rate — is the number to compare against alternatives.

Assumptions
- Cumulative deposit: interest is reinvested, not paid out.
- Rate is fixed for the full tenure; no premature withdrawal.
- Tax is applied at your marginal slab; cess is excluded.
Tips
- Senior citizens usually get 0.5% extra — enter the enhanced rate.
- Ladder deposits across tenures so some money matures every year.
- Compare the post-tax yield against debt funds and small-savings schemes.
Warnings
- Premature closure typically loses 0.5–1% of the contracted rate.
- Deposit insurance (DICGC) covers ₹5 lakh per bank per depositor.
