- What it is:
- A calculator for the Government of India Post Office Monthly Income Scheme.
- What it calculates:
- The exact monthly interest payout, total 5-year earnings, and premature encashment values.
Key Assumptions
- The deposit is kept for the full 5-year statutory term without premature withdrawal.
- Monthly interest is credited each month based on the notified sovereign rate.
How it works
The Post Office Monthly Income Scheme (POMIS) is a sovereign-backed savings program offering guaranteed monthly interest payments over a fixed 5-year tenure.
Statutory maximum deposit limits were increased in Finance Act 2023: up to ₹9 Lakhs for a single account and up to ₹15 Lakhs for a joint account (held by up to 3 adults).
Interest is paid out on a simple monthly basis and credited automatically to your Post Office Savings Account. Undrawn monthly interest does not earn any extra return.
The scheme has a lock-in period of 5 years. Premature encashment is permitted after 1 year with a deduction: 2% deducted from principal if closed between 1 and 3 years; 1% deducted if closed between 3 and 5 years.
Interest earned is fully taxable as income from other sources at your slab rate, but the Post Office does not deduct TDS at source.
Formula
Monthly Payout = (Deposit x r) / 1200 | Total 5-Yr Interest = Monthly Payout x 60
- Deposit
- = deposit in rupees (max ₹9L single, ₹15L joint)
- r
- = annual sovereign interest rate in percent (e.g. 7.4%)
Simple monthly interest credited directly to your savings account. Principal is refunded in full at the end of 5 years.
