What Is a Post Office MIS Calculator?
A Post Office MIS calculator works out the monthly income from the Post Office Monthly Income Scheme — a government scheme that pays a fixed monthly amount — using your investment, account type, and the 7.4% rate.
POMIS is a monthly income scheme, not a growth one. Unlike PPF or NSC it does not compound — it pays interest into your account every month, and returns your principal at the end of 5 years. The calculator shows that monthly income and the yearly and 5-year totals.
The limit depends on the account type. A single account allows up to ₹9 lakh and a joint account up to ₹15 lakh — both raised in Budget 2023. At 7.4%, ₹9 lakh pays ₹5,550 a month and a ₹15 lakh joint account pays ₹9,250 a month.
See what you keep after tax. POMIS gives no Section 80C deduction, and the monthly interest is taxed at your slab (the post office deducts no TDS, so you declare it). Set your slab — and the senior toggle, since seniors get a ₹50,000 80TTB exemption — and the calculator shows the net monthly income and the real yield after inflation.
It suits anyone wanting steady, safe income. Backed by the government and open to all ages, POMIS is popular with retirees, homemakers, and anyone who wants a dependable monthly cheque without market risk. The calculator shows exactly what that cheque will be, before and after tax.

How It Works
Calculate Your POMIS Income in Three Steps
02
Pick the account type
Choose single or joint — a joint account raises the limit to ₹15 lakh and splits the income between holders.
03
Read your monthly income
See the monthly and annual income, the total interest over 5 years, and the principal you get back.

The Formula
How POMIS Income Is Worked Out
01
Monthly income
Monthly = Investment × rate ÷ 12
POMIS pays simple interest every month — the annual rate divided by twelve, applied to the principal. It does not compound, because the interest is paid out, not reinvested.
Example: ₹9,00,000 × 7.4% ÷ 12 = ₹5,550 a month
02
Annual & total income
Annual = Investment × rate · Total = Annual × 5
Twelve monthly payouts make the annual income; over the 5-year term you receive five years of it. The principal is returned separately at maturity.
Example: ₹66,600 a year × 5 = ₹3,33,000 of interest
03
Account limit
Single ≤ ₹9 lakh · Joint ≤ ₹15 lakh
The maximum depends on the account type. Money above the limit cannot be invested in POMIS at all — the calculator caps the eligible amount and flags the excess.
Example: ₹15,00,000 (joint) → ₹9,250 a month
04
Net income & real yield
Net = annual − (annual − senior 80TTB) × slab% × 1.04
The interest is taxed at your slab + 4% cess; a senior holder first deducts ₹50,000 under 80TTB. The real yield then discounts the post-tax income yield for inflation.
Example: ₹66,600 at 20% (non-senior) → net ≈ ₹52,747/yr
Worked Example
Step-by-Step Walkthrough (₹9 lakh at 7.4%)
Currency note: the example below uses a benchmark scenario priced in Indian Rupee (INR). Values are converted to US Dollar (USD) at the latest exchange rate so you can compare against your own numbers.
Scenario
An investor putting $900,000.00 into a single POMIS account at 7.4% for the 5-year term.
1
Step 1 · Monthly income
At 7.4%, the $900,000.00 principal pays a fixed amount every month.
Monthly = $5,550.00
2
Step 2 · Annual & 5-year income
Twelve payouts make $66,600.00 a year; over 5 years that adds up.
Total interest = $333,000.00
3
Step 3 · What you receive in all
You get every monthly payout plus your principal back at maturity.
Total received = $1,233,000.00
The takeaway
A ₹9 lakh POMIS pays a steady $5,550.00 every month — $333,000.00 of income over 5 years, plus your $900,000.00 principal back at the end. It is a simple, government-backed monthly income, though the interest is taxable and it earns no 80C deduction.

Common Mistakes
Post Office MIS Mistakes to Avoid
Expecting POMIS to give an 80C deduction
Why it matters
Many assume any post-office scheme saves tax. POMIS does not — the investment earns no 80C, unlike NSC or a tax-saver FD.
Fix
Use POMIS for income, not tax saving. For 80C, look at PPF, NSC, or a 5-year tax-saver FD instead.
Investing above the account limit
Why it matters
The cap is ₹9 lakh single / ₹15 lakh joint. Money above that cannot go into POMIS at all.
Fix
Pick the right account type and stay within the limit; the calculator flags any excess. Use SCSS or an FD for more.
Forgetting the interest is taxable
Why it matters
The post office does not deduct TDS, so the income feels tax-free — but it is fully taxable at your slab and must be declared.
Fix
Set your slab (and the senior toggle for the ₹50k 80TTB exemption); the calculator shows the net monthly income to plan on, and the yearly figure to declare.
Treating it as a compounding investment
Why it matters
POMIS pays interest out monthly — it does not grow. People expecting a large maturity are disappointed; only the principal comes back.
Fix
Treat POMIS as monthly income. If you want growth, reinvest the monthly payouts into an RD or SIP.
Breaking it early without checking penalty
Why it matters
Closing before maturity costs 1–2% of the deposit, reducing the income earned.
Fix
Plan POMIS as a 5-year income stream. Keep a separate emergency buffer so you don't need to break it.
Pro Tips
Get More From Your Post Office MIS
Use a joint account for a higher limit
A joint account raises the cap to ₹15 lakh, paying up to ₹9,250 a month — useful for couples wanting more monthly income.
Reinvest the income to grow it
POMIS does not compound, but you can route the monthly payouts into an RD or SIP to turn the income into long-term growth.
Pair POMIS with SCSS
POMIS pays monthly and SCSS pays quarterly at a higher rate. Seniors holding both spread dependable income across the year.
Remember to declare the interest
No TDS is deducted, but the income is taxable. Add the yearly figure to your return to stay compliant.
Reinvest at maturity
When the 5 years end, you can open a fresh POMIS with the returned principal or move it to a higher-paying option.

Glossary
Key Post Office MIS Terms
Every important term you'll encounter in this calculator and the broader topic.
- Post Office MIS (POMIS)
- A 5-year government income scheme that pays interest monthly at a fixed rate and returns the principal at maturity. Open to all ages.
- Monthly Income
- The interest POMIS pays into your account each month — investment × rate ÷ 12. It is income, not reinvested growth.
- Single vs Joint Account
- A single account caps at ₹9 lakh; a joint account (up to three adults) caps at ₹15 lakh, with income split equally.
- Maturity
- The end of the 5-year term, when your full principal is returned. You can reinvest it or move it to another scheme.
- Premature closure
- Closing POMIS before maturity, allowed after 1 year — with a 2% penalty (years 1–3) or 1% penalty (years 3–5) on the deposit.
- Section 80C
- The tax deduction POMIS does NOT qualify for — unlike PPF, NSC, or a 5-year tax-saver FD. POMIS is an income scheme, not a tax-saving one.
- Section 80TTB
- A senior-citizen deduction of up to ₹50,000 on interest income (POMIS, SCSS, FDs combined) under the old regime — so a senior's first ₹50,000 of POMIS interest is tax-free.
- Real Income Yield
- The post-tax income yield after inflation. POMIS income is fixed for 5 years, so its real value slips as prices rise.
Help & answers
Frequently asked questions
Everything you need to know about how the Post Office MIS Calculator works.
01What is a Post Office MIS calculator?
A Post Office MIS calculator works out the income from the Post Office Monthly Income Scheme. You enter the investment, account type and rate; it returns the monthly income, the annual income, and the total interest over the 5-year term, plus the principal you get back.
02How is Post Office MIS interest calculated?
POMIS pays simple interest monthly — it does not compound. Monthly income = investment × rate ÷ 12. At 7.4%, ₹9 lakh pays ₹5,550 a month (₹66,600 a year), and the ₹9 lakh principal is returned at maturity.
03What is the monthly income on ₹9 lakh in Post Office MIS?
₹9 lakh — the single-account maximum — pays ₹5,550 every month at 7.4%. That is ₹66,600 a year, or ₹3,33,000 of interest over the 5-year term, with the ₹9 lakh principal returned at the end.
04What is the Post Office MIS interest rate for 2025-26?
The POMIS rate is 7.4% per annum for FY 2025-26. The rate is fixed when you open the account and the government reviews it each quarter for new accounts.
05What is the maximum investment in Post Office MIS?
A single account allows up to ₹9 lakh and a joint account (up to three adults) up to ₹15 lakh — both raised in Budget 2023 from ₹4.5 lakh and ₹9 lakh. The minimum is ₹1,000.
06What is the monthly income on a ₹15 lakh joint account?
A ₹15 lakh joint account pays ₹9,250 a month at 7.4% — ₹1,11,000 a year. The income is shared equally among the joint holders, and the ₹15 lakh is returned at maturity.
07Is Post Office MIS eligible for 80C?
No. Unlike NSC or a 5-year tax-saver FD, a POMIS investment does not qualify for a Section 80C deduction. The monthly interest is also fully taxable at your slab — POMIS is an income scheme, not a tax-saving one.
08Does the post office deduct TDS on MIS interest?
No, the post office does not deduct TDS on MIS interest. But the income is still taxable — you must add it to your total income and declare it in your return.
09How much POMIS income do I keep after tax?
Your monthly income minus the tax at your slab. Seniors also get a ₹50,000 interest exemption under Section 80TTB. Set your slab and the senior toggle in the calculator to see the net monthly income.
10Does Post Office MIS beat inflation?
Often barely, after tax. At 7.4% a non-senior in the 20–30% bracket nets about 5–6%, close to 6% inflation — so the fixed income's purchasing power slips over the 5 years. The calculator shows the real income yield.
11POMIS vs SCSS — which gives more income?
SCSS pays a higher rate (8.2% vs 7.4%) and a larger ₹30 lakh limit, but it is only for those aged 60+. POMIS is open to everyone, pays monthly, and caps at ₹9 lakh single / ₹15 lakh joint. Seniors often hold both.
12Can I withdraw Post Office MIS before 5 years?
Yes, after 1 year, with a penalty. Closing between 1 and 3 years deducts 2% of the deposit; between 3 and 5 years, 1%. There is no penalty if you stay the full 5 years.
13What happens to my POMIS money at maturity?
You get your full principal back after 5 years, having received monthly income throughout. You can reinvest the principal in a fresh POMIS account or move it to SCSS, an FD, or another scheme.
14Is this Post Office MIS calculator free and accurate?
Yes — it is free, needs no sign-up, and runs in your browser. It uses the simple monthly-payout maths POMIS follows and the 7.4% FY 2025-26 rate. Confirm the prevailing rate at the post office before investing.
