How Post Office MIS Interest Is Calculated
The Post Office Monthly Income Scheme pays simple interest on your deposited principal amount. Unlike compound interest instruments, MIS interest does not get reinvested — it is paid out to you every month directly into your savings account.
Principal: The lump sum amount you deposit at the time of opening the MIS account (between ₹1,000 and ₹9,00,000 for single accounts).
Annual Rate: The interest rate announced by the Government of India each quarter. Currently it is 7.4% per annum for Q1 FY 2025-26.
12: The number of months in a year, since interest is paid monthly.
Tenure: The scheme has a fixed 5-year (60 months) lock-in period. At maturity, your full principal is returned.
For example, if you invest ₹9,00,000 at 7.4% p.a., your monthly interest = (9,00,000 × 7.4) ÷ 1200 = ₹5,550 per month. Over 60 months, total interest = ₹3,33,000.
Practical Examples
🇮🇳 Ramesh — Retired Teacher, Lucknow
Ramesh received ₹9,00,000 from his retirement benefits. He invested the maximum single account limit in Post Office MIS at 7.4% p.a.
Monthly Interest = (9,00,000 × 7.4) ÷ 1200 = ₹5,550/month
Total Interest over 5 years = ₹5,550 × 60 = ₹3,33,000
Amount returned at maturity = ₹9,00,000 (principal)
✅ Verified: Total value after 5 years = ₹12,33,000
🇮🇳 Priya & Suresh — Joint Account, Chennai
Married couple Priya and Suresh opened a joint MIS account with ₹15,00,000 at 7.4% p.a. to supplement their household income.
Monthly Interest = (15,00,000 × 7.4) ÷ 1200 = ₹9,250/month
Total Interest over 5 years = ₹9,250 × 60 = ₹5,55,000
Amount returned at maturity = ₹15,00,000 (principal)
✅ Verified: Total value after 5 years = ₹20,55,000
🇮🇳 Anita — Homemaker, Jaipur
Anita invested ₹4,50,000 from her savings in a single MIS account at 7.4% to earn a steady monthly income.

Total Interest over 5 years = ₹2,775 × 60 = ₹1,66,500
✅ Verified: Total value after 5 years = ₹6,16,500

What Is the Post Office Monthly Income Scheme?
The Post Office Monthly Income Scheme (POMIS) is a government-backed savings instrument offered by India Post. It is designed for individuals who want a guaranteed, risk-free monthly income from a one-time lump sum deposit. The scheme is particularly popular among retirees, homemakers, and conservative investors who prioritize capital safety over high returns.
You deposit a lump sum amount (minimum ₹1,000, maximum ₹9,00,000 for single and ₹15,00,000 for joint accounts) for a fixed tenure of 5 years. Every month, the post office credits the interest amount directly to your linked savings account. At the end of 5 years, your original principal is returned in full.
Since it is backed by the Government of India under the Ministry of Finance, your investment carries sovereign guarantee — meaning both principal and interest payments are virtually risk-free. The interest rate is revised quarterly by the government and currently stands at 7.4% per annum.
