How the Post Office MIS pays monthly income

The Post Office Monthly Income Scheme is exactly what it says: deposit a lump sum (up to ₹9 lakh single / ₹15 lakh joint), receive fixed monthly interest at ~7.4% for 5 years, and get the full capital back at maturity. The calculator turns your deposit into the monthly cheque.

ExampleA joint account with the full ₹15 lakh at 7.4% pays ₹9,250 every month — ₹5.55 lakh of income over the term, with the ₹15 lakh returned at the end. It’s the small-savings family’s answer to “I need monthly cash flow from a safe lump sum” — rent-like income without a tenant.

FAQs
Can I exit the MIS early?

After 1 year, yes with a haircut: closing between years 1-3 costs 2% of the deposit, and between 3-5 years costs 1%. No exit at all in the first year. The monthly payouts continue until closure, so the penalty is the only real cost of an early exit.

MIS or SWP from a mutual fund for monthly income?

MIS guarantees the payout and the capital — an SWP guarantees neither but historically grows the corpus if withdrawals stay moderate, and is taxed more gently (part-capital, part-gain vs fully-slab interest). Retirees commonly run both: MIS/SCSS as the guaranteed floor for essentials, SWP for the inflation-fighting layer.
