Most people meet the post office mis calculator the same way — someone quotes a number, it sounds reasonable, and there is no easy way to check it. That is exactly the gap this guide closes. By the end of it you will know what the number is made of, where it usually goes wrong, and you will have run your own figures through our free post office mis calculator.

Prefer to start with your own figures? Use the Post Office MIS Calculator now, or continue for the formula and a worked example.

The logic, in plain language

The Post Office Monthly Income Scheme pays interest every month on your deposit at a rate set by the government, and returns the full deposit at the end of five years. The capital does not grow — only the monthly payout matters.

The formula behind it:

Monthly income = Deposit × Rate ÷ 12
Symbol What it means
Deposit Amount placed in the scheme
Rate Annual interest rate notified by the government

Nothing is rounded away quietly and nothing is assumed on your behalf. If a figure appears in the result, it came from something you entered.

Putting real figures through it

₹9,00,000 at 7.4% pays about ₹5,550 every month for five years, with the ₹9,00,000 returned at the end.

Change any one input and watch the result move — that sensitivity is the real lesson. It is far more useful than memorising a single outcome, because your own rate, tenure or contribution will never match the example exactly.

Using the Post Office MIS Calculator, step by step

  1. Open the Post Office MIS Calculator.
  2. Enter your figures. Use the ones on your statement, sanction letter or scheme document rather than a remembered number.
  3. Read the result card — the headline figure plus the breakdown that produced it.
  4. Adjust one input at a time to see what genuinely moves the outcome.
  5. Tap Download PDF to keep a copy of the calculation, with your inputs and assumptions printed on it.

The PDF takes a few seconds to build because it is a properly typeset report, not a screenshot. You will see a progress message while it is being prepared, and the download starts on its own.

Things worth knowing before you decide

  • Limits are ₹9 lakh for a single account and ₹15 lakh for a joint account.
  • Interest is taxable — there is no TDS, so declare it yourself.

Where people usually slip up

  • Expecting the deposit itself to grow — it does not.
  • Withdrawing early, which carries a penalty.

If you want to go a level deeper afterwards, read up on small savings schemes and regular income options. Both come up the moment you start comparing options seriously.
