How to Use This Calculator
Monthly Income tab
Enter your deposit amount (up to ₹9,00,000 for a single account) and the current interest rate (7.4% p.a. for FY 2025-26). The calculator shows your guaranteed monthly payout, annual income, total interest over the 5-year tenure, and the principal you receive back at maturity. It also shows the amount you would receive on premature closure after 1 year or 3 years.
Joint Account Benefit tab
Compare three strategies side by side: a single MIS account (₹9,00,000 limit), a joint account (₹15,00,000 limit, up to 3 holders), and the two single accounts strategy where both spouses open separate accounts (₹9,00,000 each = ₹18,00,000 total). See exactly how much more monthly income each strategy generates.
MIS vs SCSS vs FD tab
Enter a total investment amount and compare income from Post Office MIS (7.4%, monthly, ₹9L cap), SCSS (8.2%, quarterly, ₹30L cap, 60+ only), and bank FD (flexible rate, no cap). Toggle SCSS eligibility based on your age. For amounts above ₹30L, the calculator suggests an optimal combo strategy: maximize SCSS first, then MIS, then FD for the remainder.

The Formula
Post Office MIS uses a simple interest formula with monthly payouts. There is no compounding — interest is paid out monthly and does not earn further interest.
Monthly Income = (Deposit × Annual Rate) / 12
Where:
Deposit = Amount deposited in MIS account (₹1,000 to ₹9,00,000 for single)
Annual Rate = Current interest rate (7.4% p.a. for FY 2025-26)
12 = Number of months in a year
Example at maximum deposit:
Monthly Income = (₹9,00,000 × 7.4%) / 12 = ₹66,600 / 12 = ₹5,550/month
Total interest over 5-year tenure:
Total Interest = Monthly Income × 60 months
= ₹5,550 × 60 = ₹3,33,000
At maturity: Principal of ₹9,00,000 is returned in full.
Total payout = ₹9,00,000 + ₹3,33,000 = ₹12,33,000
Premature closure penalties:
Before 1 year: Not allowed
After 1 year but before 3 years: 2% of deposit deducted
After 3 years but before 5 years: 1% of deposit deducted
Unlike FD or PPF, POMIS does not compound interest. The monthly payout is a fixed amount for the entire 5-year tenure (as long as the rate remains unchanged). If the government revises rates, it applies only to new deposits, not existing ones.
Example
Ramesh — 62-year-old retired teacher from Jaipur, deploying ₹39,00,000 retirement corpus
Ramesh retired with ₹39,00,000 in savings. He wants guaranteed monthly income without market risk. His wife Sunita (58) is also eligible for MIS. Here is how they deploy the corpus across SCSS, MIS, and FD for maximum monthly income.
Step 1: SCSS (₹30,00,000 at 8.2%)
Step 2: MIS — Ramesh's account (₹9,00,000 at 7.4%)
Step 3: Combined result
Ramesh gets ₹26,050/month guaranteed income, government-backed. His SCSS also gives him ₹1,50,000 in Section 80C deduction. If Sunita also opens her own MIS account (₹9,00,000), they add another ₹5,550/month, bringing the household total to ₹31,600/month.
