Post Office MIS Calculator — Monthly Income Scheme
This Post Office MIS calculator works out the monthly payout, total interest and maturity value of a Post Office Monthly Income Scheme (POMIS) deposit — a government-backed scheme that pays simple interest out every month rather than compounding it, so your original deposit is returned unchanged at the end of the fixed 5-year term. Enter your deposit amount, the current rate and your account type to see all three figures.
Minimum ₹1,000. Maximum ₹9,00,000 for a single account or ₹15,00,000 for a joint account — set the account type below to see the right limit.
Currently 7.4% for FY2025-26. The rate is fixed for the full 5-year tenure once your account is opened, even if the government revises it later for new accounts.
Determines the maximum deposit allowed — it doesn't change the interest math, which applies to whatever deposit amount you enter above.

Frequently asked questions
What's the difference between a single and joint POMIS account?+
A single account allows a maximum deposit of ₹9,00,000, while a joint account (up to 3 holders) allows up to ₹15,00,000. Interest is calculated the same way on either — the account type just changes the ceiling on how much you can deposit.
Does the interest rate change during my 5-year tenure?+
No — once you open a POMIS account, the interest rate at the time of opening is locked in for the full 5-year term, even if the government revises the rate for new accounts opened afterward. This is different from a floating-rate instrument.
Is POMIS interest taxable?+
Yes — POMIS interest is fully taxable as income at your slab rate; there's no 80C deduction on the deposit and no tax exemption on the payout, unlike PPF or SSY. TDS isn't deducted at source, but you're required to declare and pay tax on it yourself.
