Post Office Monthly Income Scheme Calculator
A Post Office Monthly Income Scheme (POMIS) deposit of ₹9,00,000, the single-account maximum, pays ₹5,550 every month for 5 years at the current 7.4% rate, then returns your ₹9,00,000 in full. The calculator below takes your deposit, account type, and rate and shows the monthly income, the total interest over the 5-year term, and the maturity amount. Switch to a joint account to model the higher ₹15,00,000 ceiling.
Minimum ₹1,000. Maximum ₹9,00,000 in a single account.
Currently 7.4% (July to September 2026). Set quarterly by the Ministry of Finance.
POMIS runs for a fixed 5-year term. The rate is locked for the full term.

The math behind the calculator
POMIS pays simple interest, credited monthly, so the formula is short:
Monthly income = Deposit × (rate ÷ 100) ÷ 12- Deposit is your one-time lump sum.
- rate is the annual rate (7.4% for the July to September 2026 quarter).
- The interest is paid out to you each month, so nothing compounds. Over the fixed 5-year term you receive 60 monthly payments.
- Total interest over the term is the monthly income times 60, and the maturity value is simply your deposit returned in full.
Because the interest is simple, not compounded, POMIS is built for income rather than growth. If you want the money to grow instead of paying out, a compounding instrument like PPF or a cumulative fixed deposit suits better; POMIS is for a steady monthly cheque.
Monthly income by deposit
At the current 7.4% rate, here is what common deposit sizes pay each month, along with the annual and 5-year totals. Your principal comes back in full at the end.
| Deposit | Monthly income | Annual income | Total interest (5 years) |
|---|---|---|---|
| ₹1,00,000 | ₹617 | ₹7,400 | ₹37,000 |
| ₹2,00,000 | ₹1,233 | ₹14,800 | ₹74,000 |
| ₹5,00,000 | ₹3,083 | ₹37,000 | ₹1,85,000 |
| ₹9,00,000 (single max) | ₹5,550 | ₹66,600 | ₹3,33,000 |
| ₹15,00,000 (joint max) | ₹9,250 | ₹1,11,000 | ₹5,55,000 |
A worked example
Take the single-account maximum of ₹9,00,000 at the current 7.4% rate:
- Deposit: ₹9,00,000
- Monthly income: ₹5,550 (9,00,000 × 0.074 ÷ 12)
- Annual income: ₹66,600
- Total interest over 5 years: ₹3,33,000
- Maturity value: ₹9,00,000, your full deposit back
A joint account holding the ₹15,00,000 ceiling pays ₹9,250 a month, which is the most POMIS can pay one household. If you close early, there is a penalty: 2% of the principal if you exit between 1 and 3 years, and 1% between 3 and 5 years, with no withdrawal allowed in the first year. Closing that ₹9,00,000 account at, say, the 2-year mark would deduct 2%, or ₹18,000, returning ₹8,82,000 plus the interest already received.
Pair this calculator with the explainers
For the full POMIS rules, eligibility, deposit limits, tax treatment, and how it compares to other schemes, see the companion guide: What Is Post Office Monthly Income Scheme (POMIS). If you are 60 or older, the Senior Citizen Savings Scheme pays a higher 8.2% (quarterly) and is usually the better first choice before POMIS. For a lump sum you want to grow rather than draw monthly, compare a fixed deposit (use the FD calculator).

Frequently asked questions
What interest rate does the POMIS calculator use?
It defaults to 7.4% per annum, the rate notified by the Ministry of Finance for the July to September 2026 quarter, unchanged since April 2023. POMIS rates are reviewed every quarter, but once you open an account the rate is locked for the full 5-year term regardless of later revisions. The rate field is editable so you can model a future rate, but 7.4% is the current number.
How is the POMIS monthly income calculated?
POMIS pays simple interest, credited monthly, so the monthly income is deposit multiplied by the annual rate divided by 12. At 7.4%, a Rs 9,00,000 single-account deposit gives 9,00,000 x 0.074 / 12 = Rs 5,550 every month for 5 years. There is no compounding, because the interest is paid out to you each month rather than reinvested.
What is the maximum I can deposit in POMIS?
Rs 9,00,000 in a single account and Rs 15,00,000 in a joint account (of up to three adults), raised from Rs 4.5 lakh and Rs 9 lakh in Budget 2023. The minimum is Rs 1,000, in multiples of Rs 1,000. At the joint-account ceiling of Rs 15,00,000, the monthly income is Rs 9,250, which is the most POMIS can pay a single household.
Do I get my deposit back at maturity?
Yes. POMIS returns your full principal at the end of the 5-year term. There is no maturity bonus (the 5% bonus applied only to accounts opened between December 2007 and November 2011 and was discontinued). So POMIS is pure income: you receive monthly interest for 60 months, then your exact deposit back.
How much monthly income does Rs 5 lakh give in POMIS?
At 7.4%, a Rs 5,00,000 deposit gives 5,00,000 x 0.074 / 12 = about Rs 3,083 a month for 5 years, then the Rs 5,00,000 back. For Rs 1 lakh it is about Rs 617 a month; for Rs 2 lakh, about Rs 1,233; for Rs 9 lakh (single maximum), Rs 5,550; for Rs 15 lakh (joint maximum), Rs 9,250.
