About the Post Office Monthly Income Scheme Calculator
The Post Office Monthly Income Scheme (POMIS) Calculator estimates your guaranteed monthly interest income from India Post's MIS investment. Enter your investment amount, the rate used on this page, and tax bracket to see gross and after-tax monthly income, maturity value, and how reinvesting the monthly payout can grow your wealth.
The Post Office MIS is one of India's most popular fixed-income investments, offering guaranteed monthly payouts backed by the Government of India. This page uses a 7.4% annual rate assumption and models the account-type deposit limits directly: ₹9 lakh for a single account and ₹15 lakh for a joint account.
The investment comparison table shows monthly income across different investment amounts, while the reinvestment scenario demonstrates how systematically reinvesting monthly payouts at an assumed rate can significantly boost total returns over the 5-year tenure. It is useful when comparing POMIS to bank FDs, recurring deposits, or other conservative income products because the monthly payout structure makes the cash flow easy to forecast. You can also use it to estimate the after-tax value of the interest if you fall into a higher slab or want to plan around TDS. The example illustrates a single investment case, but the same logic applies across the allowed account limits and different tax assumptions.
When This Page Helps
POMIS is ideal for investors seeking guaranteed monthly income. This calculator shows exact monthly payouts, after-tax returns based on your tax bracket, and the compounding benefit of reinvesting monthly income — essential for retirement income planning in India. It also gives a clear way to compare safety and liquidity trade-offs before choosing a fixed-income option.
How to Use the Inputs
- Enter your investment amount (₹1,000 minimum).
- Choose single or joint account type so the correct deposit cap is used.
- Confirm the rate used on this page before relying on the estimate.
- Select the tenure (5 years standard).
- Enter your income tax bracket percentage.
- Enter a reinvestment rate for growth scenarios.
- Review monthly income and comparison tables.
Formula used
Monthly Interest = (Investment × Annual Rate) ÷ 12
Annual Interest = Investment × Rate
Total Interest = Annual Interest × Tenure
Maturity Value = Investment + Total Interest
Effective Rate = (Annual Interest × (1 − Tax Rate)) ÷ Investment × 100Example Calculation
Result: Monthly income: ₹3,083 (₹2,467 after tax)
Annual interest: ₹37,000. Monthly gross: ₹3,083. After 20% tax: ₹2,467/month. Total interest over 5 years: ₹1,85,000. Maturity: ₹6,85,000.
Tips & Best Practices
- At ₹15 lakh (joint max) at 7.4%, you earn ₹9,250/month gross.
- Reinvesting monthly income in a recurring deposit can compound your returns significantly.
- Compare POMIS returns with bank FD and other small-savings rates before locking in a 5-year plan.
- The 5-year lock-in aligns well with medium-term retirement income planning.
POMIS vs Bank Fixed Deposits
POMIS offers a fixed monthly payout backed by the Government of India, which makes it useful for investors who care more about predictable cash flow than market-linked growth. The right comparison is not just headline rate versus an FD, but also payout frequency, liquidity, renewal terms, and the role of the investment inside your wider income plan.
Tax Planning with POMIS
Interest from POMIS is taxable, so after-tax income can differ meaningfully from the headline monthly credit. Use the tax-rate field here as a planning assumption, then confirm the actual withholding and return treatment that applies to your situation before making a final decision.
The Reinvestment Strategy
Simply receiving ₹3,083/month from a ₹5 lakh POMIS generates ₹1,85,000 over 5 years. But reinvesting that income at even 6% annually in a recurring deposit or mutual fund can generate an additional ₹15,000-20,000 in compound interest — turning passive income into active wealth building.

Methodology
This page models the Post Office Monthly Income Scheme as a fixed-income worksheet. It caps the deposit at the current scheme limit for the selected account type, calculates monthly interest as deposit multiplied by the annual rate divided by 12, and then shows a simple after-tax view by applying the user's entered tax-rate assumption to the annual interest. The reinvestment section separately compounds each monthly after-tax payout at the user-entered reinvestment rate to illustrate what could happen if the monthly income is deployed elsewhere rather than spent.
It is a planning worksheet, not a substitute for the notified scheme rules, the current quarterly small-savings rate notice, or personal tax advice. Actual tax treatment, renewal decisions, and any forms or withholding requirements depend on the investor's current situation and the rules in force at that time.

Frequently Asked Questions
This page uses a 7.4% annual rate paid monthly. The government reviews and sets small-savings rates periodically, so confirm the notified rate before investing.
The scheme limit used here is ₹9 lakh for a single account and ₹15 lakh for a joint account. The minimum deposit is ₹1,000 in multiples of ₹1,000.

Premature withdrawal is allowed after 1 year with a penalty of 2% (if before 3 years) or 1% (after 3 years). No withdrawal is permitted in the first year.
The principal amount is returned in full. If not withdrawn, the account can be renewed for another 5-year term at the prevailing rate. That means the account does not disappear automatically, but your renewal terms will follow whatever rate applies at the time.
