Post Office FD Calculator
This post office FD calculator works out the maturity value of a Post Office Time Deposit (POTD) — India Post's version of a fixed deposit — using the same quarterly-compounding convention as a bank FD. Enter your deposit amount, pick your tenure (1, 2, 3 or 5 years, the only durations India Post offers) and the current rate for that tenure, and see exactly what you'll receive at maturity.
The lump sum you are placing in the Post Office Time Deposit. India Post requires a minimum of ₹1,000, with no maximum limit.
Post Office Time Deposits only come in four fixed tenures — you can't choose any arbitrary duration the way you sometimes can with a bank FD.
The rate depends on which tenure you picked above — 1/2/3/5-year Post Office Time Deposit rates differ and are revised quarterly by the government, so check the current India Post rate card rather than relying on the default.
Maturity value

What you'll receive in one lump sum when the Time Deposit matures — e.g. ₹1,00,000 at 7.5% for 5 years matures to about ₹1,44,995.
The pure gain on your deposit — remember this is taxable at your income slab rate in the year it's credited, same as a bank FD.
Frequently asked questions
How is Post Office FD (Time Deposit) interest calculated?+
Using the same quarterly-compounding formula as a bank FD, A = P(1 + r/4)^(4t): principal times (1 + quarterly rate) to the power of total quarters. ₹1,00,000 at 7.5% for 5 years matures at about ₹1,44,995.
Which Post Office Time Deposit tenure gets a tax deduction?+
Only the 5-year Time Deposit qualifies for a Section 80C deduction on the deposited principal. The 1-year, 2-year and 3-year Time Deposits do not carry this benefit, even though all four use the same quarterly-compounding maturity formula.
Is a Post Office FD safer than a bank FD?+
They're both very low-risk, but the backing differs: a Post Office Time Deposit carries a direct sovereign guarantee from the Government of India, while a bank FD is covered by DICGC deposit insurance only up to ₹5 lakh per depositor per bank. For amounts above ₹5 lakh, that difference becomes more meaningful.
Can I withdraw a Post Office Time Deposit before maturity?+
Generally not before 6 months. After that, rules are stricter than most bank FDs — only the 5-year Time Deposit allows closure after 4 years, at a lower rate than originally quoted. Always confirm the current premature-withdrawal rules at your post office, since these have changed over time.
Post Office FD or bank FD — which pays more?+
It varies by tenure and changes quarterly for both, so there's no fixed answer — compare the current India Post Time Deposit rate card against your bank's FD rates for the same tenure using this calculator and our regular FD calculator side by side.
