Retirement Calculator

Two numbers decide a retirement plan: the pot you need on the day you stop working, and what building it costs every month from now. The first depends almost entirely on inflation, because it is today's lifestyle priced decades out. Already retired and drawing down instead? Use the SWP calculator.

Where the Corpus Comes From

Corpus Needed at 65

₹4,24,05,577

Saving ₹7,768 a month for 35 years puts in ₹32,62,560 of your own money; growth at 12% supplies the other ₹3,91,43,017. The monthly figure is a level sinking fund at the monthly equivalent of 12%, derived as 1.121/12 − 1 — not 12 ÷ 12, and not 0.12% as some calculators compute it.

Worked Example: Retiring at 65 on Today's ₹50,000 a Month

You are 30 and spend ₹50,000 a month. In 35 years, at 5% inflation, the same lifestyle costs ₹2,75,801 a month. Funding that for 25 years — while it keeps rising with inflation and the untouched balance keeps earning 12% — needs ₹4,24,05,577 on the day you stop working.

The assumptions matter more than the arithmetic

This funds exactly 25 years from age 65 and assumes a steady 12% throughout, including after you retire. It ignores medical costs, which inflate faster than anything else in the basket, and it ignores tax on withdrawals. Move inflation up two points and watch the corpus move — that sensitivity is the real output of this page.

What this Calculator Does

It inflates your current monthly spending to what it will cost at 65, then works out the pot that funds 25 years of that spending while it keeps rising with inflation and the untouched balance keeps earning. The monthly saving is a level sinking fund at the monthly equivalent of your assumed return.

How to Use It

1

Set your age and what you spend a month today.

2

Pick the lifestyle you want in retirement, or set the inflation rate directly.

3

Pick where you will save it — safe or aggressive — or set the return directly.

4

Read the corpus required and the monthly saving, then move inflation two points and watch both.

What It Does Not Include

It funds exactly 25 years from age 65 and assumes a steady return throughout, including after you retire. Medical costs are not separated out, though they inflate faster than anything else in the basket. Tax on withdrawals, EPF and NPS balances you already hold, and any pension or rental income are all excluded — so treat the corpus as the gross target, not the shortfall.

Expert FAQ

Frequently Asked Questions

It depends almost entirely on what you spend and what inflation does, not on a round number. Someone aged 30 spending ₹50,000 a month today needs roughly ₹4.2 crore at 65 on a 5% inflation assumption — because ₹50,000 of lifestyle costs about ₹2.76 lakh a month by then.
Today's monthly spending is inflated to the retirement date, then multiplied by a factor that accounts for 25 years of withdrawals growing at inflation while the remaining balance earns the assumed return. It is a geometric series in (1 + inflation) ÷ (1 + return), not a flat multiple.
Because the 25x shorthand uses today's spending. The pot has to fund spending at retirement-date prices, which after thirty years of 6% inflation is nearly six times higher. The multiple is right; the figure you apply it to is not.
As a sinking fund: the level monthly amount whose future value equals the corpus, compounded at the monthly equivalent of your annual return. We derive that as (1 + r)^(1/12) − 1, because the rate you enter is an effective annual return — not r ÷ 12, and not r ÷ 100 as some calculators compute it.
Yes. On the same assumptions, starting at 25 needs about ₹5,579 a month and starting at 45 needs about ₹22,385 — four times as much, even though the later start needs a smaller pot. The lost compounding outweighs the smaller target.
Match it to where the money will sit. Around 8% is reasonable for PF and deposits, around 12% for a long-run equity allocation. Be more conservative the closer you are to retiring, because a bad final few years cannot be made up.
Yes, and this calculator does not. The corpus here is the total target, so subtract what your EPF, NPS and existing investments are projected to be worth at 65 to get the genuine shortfall. Use the lumpsum calculator to project each existing balance forward.
They are the conventional planning assumptions and they match what most Indian calculators use, which makes the output comparable. If you plan to stop earlier, the pot has to be larger and last longer — the FIRE calculator is built for that case.
Not separately, and that is its biggest omission. Healthcare inflation in India runs well above headline CPI, and the bulk of it arrives late in retirement when the corpus is smallest. Raising the inflation assumption is a crude but useful way to make room for it.
Once a year, and after any real change in income or spending. The figure moves most with your current spending level, which drifts upward quietly — a plan built on what you spent five years ago is funding a lifestyle you no longer have.
