The Post Office MIS Payout Formulas
POMIS interest is calculated annually and paid out monthly ($1/12 ext{th}$ of annual interest).
Annual Interest Income = Lump Sum Deposit * (Interest Rate / 100)
Monthly Income Payout = Annual Interest Income / 12
Total 5-Year Interest Payout = Monthly Income Payout * 60 Months
Total Capital Returned at Maturity = Original Lump Sum Deposit
Practical Post Office MIS Calculation Examples
Example 1: Maximum Single Account Deposit (₹9,00,000 at 7.4% p.a.)
An investor deposits the maximum single account limit of ₹9,00,000 in POMIS at 7.4% interest rate.
- Lump Sum Deposit: ₹9,00,000
- Annual Interest (7.4%): ₹9,00,000 × 0.074 = ₹66,600 / year
- Guaranteed Monthly Payout: ₹66,600 / 12 = ₹5,550 / month
- Total Interest Received over 5 Years (60 Months): ₹5,550 × 60 = ₹3,33,000
- Principal Returned at 5-Year Maturity: ₹9,00,000
Example 2: Maximum Joint Account Deposit (₹15,00,000 at 7.4% p.a.)
A retired couple opens a joint POMIS account depositing ₹15,00,000.
- Lump Sum Deposit: ₹15,00,000
- Annual Interest: ₹1,11,000
- Guaranteed Monthly Payout: ₹9,250 / month
- Total Interest Received (5 Years): ₹5,55,000

Practical Example: Post Office MIS Calculation

- Base Financial Value: ₹5,00,000
- Applicable Rate / Factor: 8.50% p.a.
- Period / Horizon: 5 Years
- Calculated Outcome: Using standard compounding/amortization formulas, the total projected output equals ₹7,51,830, representing a net yield/cost value tailored to current Indian tax and statutory guidelines.
Common Post Office Mis Calculator Mistakes to Avoid
- Confusing Post Office Monthly Income Scheme (POMIS) Payouts with Compounding FDs: Expecting monthly POMIS interest to compound automatically, when interest is paid out monthly into savings accounts and earns no extra interest if left unwithdrawn.
- Exceeding Single (₹9 Lakhs) or Joint (₹15 Lakhs) Individual Deposit Caps: Depositing funds above statutory individual cap limits (updated to ₹9 Lakhs for single and ₹15 Lakhs for joint accounts in 2023).
- Making Premature Withdrawals Before Completing 1 Year Lock-In: Attempting account closure within 1 year (prohibited), or closing between 1 to 3 years incurring a 2% principal penalty (1% penalty between 3 to 5 years).
- Assuming POMIS Interest is Eligible for Section 80C Tax Deduction: Claiming Section 80C tax relief on POMIS deposits or treating monthly interest as tax-exempt.
- Failing to Add Monthly Interest to Taxable Income (Income Tax Slabs): Omitting POMIS interest from annual ITR filings, paying lower estimated taxes instead of marginal slab rates.
- Ignoring Joint Account Equal Share Division Rules: Assuming unequal ownership ratios in joint POMIS accounts, when statutory rules treat joint holders as equal 50/50 capital owners.
Frequently Asked Questions
How does the Post Office MIS Calculator work?
Enter the amount you plan to invest (within the applicable deposit limit) and the current annual interest rate. The calculator divides the annual interest by 12 to show your fixed monthly income payout, and also displays the total interest earned over the 5-year maturity period along with the principal returned at maturity.
How is the monthly income from MIS calculated?
MIS pays simple interest on a monthly basis — the principal is not compounded. The monthly payout is: Monthly Income = (Principal × Annual Interest Rate) / 12. Your principal remains intact and is returned in full when the scheme matures after 5 years.
Is there a maximum investment limit for Post Office MIS?
Yes, there are deposit limits that differ between individual and joint accounts. The calculator is designed with these limits in mind. Check the current India Post guidelines for the exact figures, as limits may be revised periodically.
Can I reinvest the monthly interest to grow my corpus?
The MIS scheme itself pays out interest monthly and does not offer automatic reinvestment. However, you can manually transfer the monthly payouts into a recurring deposit or another savings instrument to benefit from compounding. The calculator shows the flat monthly income so you can plan how to deploy it.
What happens to the Post Office MIS deposit at maturity?
At the end of 5 years, the full principal is returned to you. You have the option to withdraw it, reinvest it in a fresh MIS account, or move it to another scheme. There is a premature withdrawal option after a lock-in period, though a penalty may be deducted from the interest earned depending on when you withdraw.
Can I invest more than ₹9,00,000 in MIS?
Individual limit is ₹9,00,000. Joint account limit is ₹18,00,000. Investments beyond this are not accepted.
Is MIS interest taxable?
Yes, fully taxable as income. If annual interest exceeds ₹10,000, TDS is deducted. File ITR to claim refund if applicable.
Can I increase my MIS investment after opening?
No, investment amount is fixed at maturity. To invest more, open a separate MIS.
What happens if I withdraw at 4 years?
You can withdraw 50% of balance after 1 year. At 4 years, remaining principal + accrued interest for 4 years is paid.
Is MIS better than bank savings for income?
Yes, 7.4% vs 3% is significant. But MIS has 5-year lock-in while bank savings is liquid.
