Report tool

What is the Post Office Monthly Income Scheme (POMIS)?

POMIS is a government-backed savings scheme offered by India Post. Depositors receive fixed monthly interest payouts while the principal is returned at maturity. The scheme suits retirees and conservative investors seeking predictable income. All math runs in your browser.

For long-term retirement accumulation with market-linked returns, compare with the National Pension Scheme calculator. For general fixed-deposit math, see the maturity value calculator.

POMIS interest formulas

Monthly interest is the annual rate divided by 12 and applied to the principal:

Monthly Interest=P×r12\text{Monthly Interest} = \frac{P \times r}{12}

Total interest over the tenure and maturity amount:

Total Interest=Monthly Interest×months\text{Total Interest} = \text{Monthly Interest} \times \text{months}
Maturity Amount=P+Total Interest\text{Maturity Amount} = P + \text{Total Interest}

Worked example

A single-account deposit of Rs 1,00,000 at 7.4% per annum for 5 years (60 months), using rates effective April 1, 2025.

  • Monthly interest = (1,00,000 x 7.4%) / 12 = Rs 616.67
  • Total interest = Rs 616.67 x 60 = Rs 37,000
  • Maturity amount = Rs 1,00,000 + Rs 37,000 = Rs 1,37,000

Key POMIS features

Standard POMIS has a 5-year lock-in. Interest is paid monthly and credited to a linked savings account. Deposit limits differ for single (up to Rs 9 lakh) and joint (up to Rs 15 lakh) accounts. Interest rates are notified quarterly by the Government of India through India Post.

Frequently asked questions

What is the current POMIS interest rate?
The default rate in this calculator is 7.4% per annum, effective April 1, 2025 for FY 2025-26. India Post revises rates quarterly; check the official notification for the latest figure.
Is POMIS interest taxable?
Yes. Interest from POMIS is fully taxable as income under Indian tax law. Tax is not deducted at source (TDS) by default, so depositors must report interest in their income tax return.
Can I withdraw POMIS before 5 years?
Premature withdrawal is allowed after 1 year with a penalty. Within 1 to 3 years, 2% of the deposit is deducted. After 3 years, 1% is deducted. Early exit forfeits some principal.
What is the difference between single and joint POMIS accounts?
A single account allows deposits up to Rs 9 lakh. A joint account (up to 3 adults) allows up to Rs 15 lakh. Interest calculation is the same; only deposit limits and account ownership differ.
Is POMIS principal safe?
POMIS is backed by the Government of India through India Post. It carries sovereign guarantee on principal and declared interest, making it one of the safest fixed-income options in India.
