At an assumed 10.0% return, the corpus supports every withdrawal through the full tenure, ending with ₹84,98,427 still invested.
If withdrawals kept going on what is left
Effectively indefinitely
The ₹84,98,427 left over earns more each year than the withdrawal takes, so at this assumed return the payouts do not run out inside a 50-year projection beyond the plan.
Your ₹50 Lakhs grows by ₹1.19 Crs over 20 yrs. Of it, you keep ₹78.16 Lakhs, ₹5.84 Lakhs goes in tax, and ₹84.98 Lakhs is left.

Each withdrawal is treated as a partial redemption of units bought at the start, so the gain inside an instalment is whatever the value has risen since. Tax is shown against each instalment to give what you keep. A fund does not deduct it for a resident investor: you receive the full withdrawal and pay the tax when you file.

Before you rely on these numbers
- This is an illustrative tool, not investment advice and not a recommendation to buy or sell any security or product.
- Every figure is a projection built on the assumptions shown, which you can change. Actual returns vary and can be negative.
- Returns are assumed to be steady year on year. Real markets are not, and a poor sequence of returns close to your goal changes the outcome even when the average does not.
- Figures are before tax, exit loads and fund charges, and assume every contribution is made on time.

What is an SWP?
An SWP (Systematic Withdrawal Plan) lets you take a fixed amount out of a mutual fund every month, while the rest stays invested and keeps growing. It works like a SIP in reverse: instead of building a corpus bit by bit, you draw a regular income from one. People often use an SWP in retirement, or to turn a lump sum into a steady monthly payout.
How to use the SWP calculator
- Enter the money. Add your initial investment, the lump sum the withdrawals come out of, and the monthly withdrawal you want to start with.
- Set how long and the return. Choose how long the withdrawals should run (1 to 40 years) and the return you expect (3% to 14% a year).
- Add a step-up if you want one. Tick the step-up option to raise your withdrawal each year, for example to keep pace with rising prices.
You will see whether the corpus lasts the full period, how much you will withdraw in total, how much of that goes in tax, what is left at the end, and a year-by-year ledger of every withdrawal.
How the SWP calculator works
- The corpus grows and pays out each month. Your investment earns a monthly rate that compounds to your annual return: (1 + annual return)^(1/12) − 1. Each month's withdrawal is paid at the end of the month.
- Each withdrawal is a partial redemption. All units are assumed to be bought at the start. Each withdrawal sells just enough units to pay it, and the gain is the rise in value of those units since you bought them.
- Tax is worked out on the gain. Gains in the first 12 months are taxed at 20% and later gains at 12.5%, as for equity-oriented funds. The ₹1.25 lakh annual exemption is not applied, and surcharge and cess are not added on top. Tax is shown against each instalment to give the amount you keep, and is not taken out of the corpus.
Worked example: You invest ₹50 lakhs and withdraw ₹35,000 a month for 20 years, a withdrawal rate of 8.4% a year, with the corpus earning 10% a year. You withdraw ₹84 lakhs in total. About ₹5.84 lakhs of that is tax, so you keep about ₹78.16 lakhs. Because the corpus earns more than you take out, it keeps growing and ends at about ₹84.98 lakhs. Tax is just ₹4,197 in the first year, when most of each withdrawal is your own money coming back, and rises to about ₹44,345 by year 20.
How long will ₹50 lakhs last?
| Monthly withdrawal | Withdrawal rate | At 6% return | At 8% return | At 10% return |
|---|---|---|---|---|
| ₹25,000 | 6.0% a year | 62 years | Indefinitely | Indefinitely |
| ₹35,000 | 8.4% a year | 20 years | 32 years | Indefinitely |
| ₹45,000 | 10.8% a year | 13 years | 16 years | 22 years |
| ₹55,000 | 13.2% a year | 10 years | 11 years | 13 years |
| ₹70,000 | 16.8% a year | 7 years | 8 years | 8 years |
For a ₹50 lakh corpus, a fixed monthly withdrawal with no step-up, and a steady return. "Indefinitely" means the corpus earns more than is withdrawn, so it never runs out at that steady return. Illustrative only; real returns vary.
SWP Calculator FAQs
SWP Calculator
It depends on your withdrawal rate, meaning your yearly withdrawals as a share of the corpus, compared with the return it earns. If the withdrawal rate stays below the return, a steady return would let the corpus last indefinitely. If it's above, the corpus shrinks over time, and the bigger the difference, the faster it runs out. The table above gives a quick guide for ₹50 lakhs.
If you're living off your SWP, a step-up helps your income keep pace with rising prices, so ₹35,000 buys roughly as much in year 10 as it does today. The trade-off is that the corpus runs down faster. Tick the step-up option to see how both choices play out.
Each withdrawal is treated as selling some of your units. Only the gain on those units is taxed, not the part that returns your own money. For equity-oriented mutual funds, gains on units held up to 12 months are taxed at 20%, and gains on units held longer at 12.5%, with the first ₹1.25 lakh of long-term gains each financial year tax-free. Cess applies on top. Rules can change, so check the current position or speak to a tax adviser.
Early on, your units haven't grown much since you bought them, so most of each withdrawal is your own money coming back, and only a small part is gain. As the years pass and the value of each unit rises, a bigger share of every withdrawal is gain, so the tax rises too.
The exemption applies once per person per financial year, across all your equity gains, not to each investment separately. Since the calculator can't know your other gains, it leaves the exemption out, which keeps the estimate on the safe side. If this SWP is your only source of equity gains, your actual tax could be noticeably lower than shown.
For resident individuals, mutual funds generally don't deduct tax from redemptions. You receive the full withdrawal and pay any tax due when you file your return, or through advance tax. The calculator shows tax against each instalment so you can see what you'll actually keep.
The tax figures assume an equity-oriented fund. Gains on debt funds bought on or after 1 April 2023 are taxed at your income tax slab rate, whatever the holding period, and other fund types have their own rules. The corpus figures still hold for any fund, but the tax shown won't match for non-equity funds.
Yes, a lot. When you're withdrawing, a fall early on means selling more units at low prices to fund the same instalment, and those units never get the chance to recover. The same fall late in the plan does far less damage. The calculator assumes a steady return, so leave yourself a margin, especially for a long SWP.
It depends on where the corpus is invested. Equity funds have historically offered higher long-run returns but with bigger swings, which matters more when you're withdrawing. Many people use hybrid or debt-oriented funds for an SWP and assume a lower return. Past returns don't guarantee future ones, so try a cautious rate as well.
They work differently. FD (opens in new tab) interest is fully taxed at your slab rate every year, while an SWP from an equity-oriented fund is taxed only on the gain portion of each withdrawal, at capital gains rates. On the other hand, FD returns are fixed, while an SWP's value moves with the market. Many people use a mix of both.
Our FD calculator shows what a deposit pays out, monthly or at maturity
Yes. Most funds let you change the amount, pause or stop an SWP at any time. Withdrawals within a set period of investing, often the first year, may attract an exit load (opens in new tab), so check your fund's terms.
Work backwards from the monthly income you want and how long it has to last. The table above gives a feel for it at ₹50 lakhs, and if the SWP is meant to fund your retirement, the retirement calculator sizes the corpus (opens in new tab) for you from what you spend today.
