Post Office MIS Calculator (India)
Find the monthly income from a Post Office Monthly Income Scheme (POMIS) deposit. Enter your deposit and the interest rate — income is paid monthly and the principal is returned after 5 years.
The Post Office Monthly Income Scheme (POMIS) is a low-risk, government-backed scheme that pays you a fixed monthly income on a lump-sum deposit. You invest once, receive interest every month for five years, and get your full principal back at maturity. It's popular with retirees and anyone wanting predictable cash flow. This calculator shows your monthly income, the total interest over five years and the principal returned.
How POMIS income is calculated
The scheme pays simple interest monthly on your deposit — the principal itself doesn't grow, it's returned intact at the end.
Total interest (5 yrs) = monthly income × 60; principal returned at maturity
| Deposit at 7.4% | Monthly income | 5-yr interest |
|---|---|---|
| ₹3,00,000 | ₹1,850 | ₹1,11,000 |
| ₹5,00,000 | ₹3,083 | ₹1,85,000 |
| ₹9,00,000 (max single) | ₹5,550 | ₹3,33,000 |
Worked example
Depositing the single-account maximum of ₹9,00,000 at 7.4%:
| Monthly income = 9,00,000 × 7.4 ÷ 1200 | ₹5,550 |
| Total interest over 5 years | ₹3,33,000 |
| Principal returned at maturity | ₹9,00,000 |
Who POMIS suits
POMIS is ideal if you want a steady, guaranteed monthly payout without touching your capital — for example, a retiree supplementing a pension. The trade-off is that the income is fixed and taxable, and there's a 5-year lock-in with a small penalty for premature closure. Because the principal doesn't compound, total returns are lower than a scheme that reinvests interest, but the monthly certainty is the whole point.
