How it's calculated
The Post Office Monthly Income Scheme pays interest every month on the amount you deposit: monthly income = deposit × annual rate ÷ 12. The deposit is locked for 5 years and returned in full at maturity. The limit is ₹9 lakh for a single account and ₹15 lakh for a joint account of up to three adults — and each holder's share, including shares in joint accounts, counts towards ₹9 lakh. The minimum is ₹1,000 in multiples of ₹1,000.
Example: at 7.4%, ₹9 lakh earns ₹5,550 a month and ₹15 lakh earns ₹9,250 a month.
The rate is fixed for the account when you open it. Interest is not compounded — to compound it, reinvest each month's payout yourself (for example in a recurring deposit or SIP). Closing after one year but before three costs 2% of the deposit; after three years, 1%.
