How the Post Office MIS Calculator works

MIS pays 7.4% a year as monthly interest for a 5-year tenure. The government sets small savings rates every quarter. This guide uses the rates the calculator uses, notified for Jul–Sep 2026.

The maximum deposit is ₹9 lakh in a single account and ₹15 lakh in a joint account.

Your principal comes back after 5 years. The monthly interest is taxable.

Formula

Monthly income = P × r ÷ 12

• P = amount deposited
• r = 7.4% a year (as a decimal)

Worked example: ₹9,00,000 in a single MIS account

1. Yearly interest = ₹9,00,000 × 7.4% = ₹66,600.
2. Monthly income = ₹66,600 ÷ 12 = ₹5,550.
3. Over 5 years you receive ₹3,33,000 in interest.
4. At the end of 5 years, the ₹9,00,000 is returned.

Tips

• Each ₹10,000 deposited pays about ₹62 a month.
• A joint account allows up to ₹15 lakh, for a larger monthly income.
• MIS interest is simple and paid out, so it does not compound unless you reinvest it.
