SWP Calculator
See how long a corpus lasts when you withdraw from it every month — and the month it would run out.
What the SWP calculator does
An SWP calculator models a systematic withdrawal plan: a fixed monthly payout from an existing corpus that keeps growing on whatever is left. The figure that matters is not the closing balance but whether the money lasts — this calculator names the month the corpus would be exhausted, rather than showing a balance of zero.

This is arithmetic, not a forecast — the output is a mathematical projection of the assumptions you entered. Illustration only, computed from the assumptions shown — not a forecast, a projection of any scheme's performance, or a guarantee.

How the SWP calculation works
Each month: balance = (balance − withdrawal) × (1 + i), i = (1 + r)^(1/12) − 1
The withdrawal is taken at the START of the month and the remainder grows for that month, which is how AMCs process an SWP mandate. The monthly rate is the twelfth root of the annual rate rather than the annual rate divided by twelve: dividing turns an assumed 12% into an effective 12.68%, which quietly overstates how long a corpus lasts. Each month is stepped individually so a corpus that runs out does so on the right month rather than at a closed-form average.
Frequently asked questions
How long will my money last in an SWP?
It depends on three things: the size of the corpus, how much you withdraw each month, and what the remaining balance earns. If withdrawals are smaller than the growth on the balance, the corpus never depletes. If they are larger, it drains — and the calculator shows the month it runs out rather than simply displaying a zero balance at the end.
How much can I safely withdraw each month?
The calculator solves this directly: enter the corpus and how long it must last, and it returns the monthly amount that ends at exactly zero over that period. Remember that a fixed withdrawal loses purchasing power every year, so a plan that works in today's rupees may not in fifteen years' time — the step-up option models that.
Is an SWP taxed?
Yes, and this is the most misunderstood part of an SWP. Each withdrawal is a redemption of units, so it is a capital gains event. Only the GAIN portion of each withdrawal is taxable, not the whole amount — you are partly receiving your own capital back. The applicable rate depends on the fund type and how long those specific units were held, and units are redeemed first-in-first-out.
Is an SWP better than a dividend or IDCW option?
They are different mechanisms and neither is universally better. An SWP gives you a predictable amount on a date you choose and is taxed as capital gains on the gain portion; an IDCW payout is decided by the AMC, is not guaranteed in amount or timing, and is added to your income and taxed at your slab rate. Which suits you depends on your tax position, which is worth discussing with a qualified adviser.
Does an SWP guarantee a monthly income?
No. The withdrawal amount is fixed but the corpus funding it is not — it rises and falls with the market. A period of poor returns early in the plan drains the corpus faster than the same returns later, because there is less capital left to recover. Any figure here is arithmetic on an assumed rate, not a projection of what will happen.

Withdrawing regularly makes the exit load matter. This lists schemes whose disclosed load is nil. GrowIQ Capital is an AMFI-registered distributor, not an investment adviser: it can tell you what each scheme’s terms are and transact for you, and it does not rate or recommend schemes.
