This free SWP calculator helps you estimate what happens when you withdraw a fixed amount regularly from an existing investment, such as a mutual fund — a facility commonly called a Systematic Withdrawal Plan (SWP). Enter your investment amount, the amount you'd like to withdraw at regular intervals, an assumed annual rate of return and the period you want to model, and the calculator shows the estimated total amount withdrawn, the estimated profit earned, and the estimated remaining corpus at the end of the period, along with a year-wise breakdown. This is useful for anyone testing whether a given withdrawal amount looks sustainable, or exploring retirement-style income scenarios from an investment corpus. An SWP is not fixed-interest income — the underlying investment remains market-linked, so actual results can differ meaningfully from any single assumed rate used here.
Total Withdrawal
Profit Earned
Remaining Corpus
This table shows, year by year, how much was withdrawn, how much the remaining balance earned under the assumed return, and what balance carried forward into the next year — useful for seeing exactly when and how a corpus grows, shrinks, or gets depleted under your chosen inputs.
SWP stands for Systematic Withdrawal Plan. It is generally a facility offered by mutual funds through which units from an existing investment are redeemed periodically — commonly every month — to pay out a fixed amount the investor has chosen, according to the withdrawal instructions set up with the fund. The remainder of the investment stays invested and continues to be exposed to the market, so its value can rise or fall depending on how the underlying fund performs. An SWP is not the same as earning fixed monthly interest — the withdrawal amount is fixed by the investor, but the value of the underlying investment is not fixed at all.
This calculator models each month in a fixed sequence: the monthly withdrawal is deducted from the balance first, and the assumed monthly return is then applied to whatever balance remains after that withdrawal. In other words, returns are only ever earned on the amount that stays invested after that month's withdrawal is taken out — not on the amount already paid out. This repeats every month for the tenure you enter, or until the corpus is exhausted, whichever comes first. Concretely, for each month:
where the Monthly Rate is the entered annual return divided by 12 and by 100. Profit Earned is then calculated as: Total Amount Withdrawn + Remaining Corpus − Initial Investment, which captures the total estimated growth generated over the tenure, whether it was paid out through withdrawals or left in the remaining balance.
Here is a worked example, calculated using this calculator's own logic — treat it as illustrative only:
Investment: ₹10,00,000 | Monthly Withdrawal: ₹10,000 | Expected Return: 10% p.a. (assumed) | Tenure: 5 years
Total Withdrawal: ≈ ₹6,00,000 | Profit Earned: ≈ ₹4,64,485 | Remaining Corpus: ≈ ₹8,64,485
A second example, sized for a retirement-style monthly income scenario over a longer period:
Investment: ₹20,00,000 | Monthly Withdrawal: ₹15,000 | Expected Return: 8% p.a. (assumed) | Tenure: 10 years
Total Withdrawal: ≈ ₹18,00,000 | Profit Earned: ≈ ₹14,76,795 | Remaining Corpus: ≈ ₹16,76,795
Set the calculator above to either set of values and it will reproduce these figures exactly. Remember that the return rates used are assumptions chosen for illustration, not promised or typical returns for any real product.
A useful way to think about an SWP is its withdrawal rate — how much you're taking out each year relative to your starting corpus:
For example, withdrawing ₹1,20,000 a year (₹10,000 a month) from a ₹10,00,000 corpus works out to a 12% initial withdrawal rate. This is purely an illustrative metric to help you compare scenarios — it is not a recommendation, and there is no single withdrawal rate that is "safe" for everyone, since the right figure depends on your actual returns, how long the withdrawals need to last, and your broader financial situation.
A higher monthly withdrawal reduces the remaining corpus faster, since more is being taken out of the balance each month before any growth is applied. A lower withdrawal leaves more capital invested, giving it more room to benefit from assumed growth over time. Whether a given withdrawal amount is sustainable for a particular corpus depends on several factors together: the withdrawal amount itself, how often it's taken, the size of the starting corpus, the assumed and actual returns, the duration you need the withdrawals to last, and any fees or taxes that apply. Try a few different withdrawal amounts in the calculator above against the same corpus and return assumption to see how sensitive the remaining balance is.
The assumed annual return has a large effect on how a corpus behaves under regular withdrawals. For example, keeping a ₹10,00,000 corpus and a ₹10,000 monthly withdrawal constant over 10 years, but changing only the assumed annual return, produces very different estimated remaining corpus figures: roughly ₹1,72,409 at 6%, roughly ₹3,77,983 at 8%, and roughly ₹6,41,521 at 10%. These are mathematical results of this calculator's model for the rates tested — not a prediction of what any real investment will actually return.
Extending the tenure you model increases both the total amount withdrawn over that period and the length of time the remaining corpus is exposed to assumed growth and ongoing withdrawals. A corpus that looks comfortable over 5 years may shrink or deplete faster than expected over 15 or 20 years if the withdrawal amount isn't adjusted, because withdrawals continue compounding against the balance for longer. Testing a few different tenures in the calculator is a useful way to see how time changes the picture for your specific numbers.
Yes. If the monthly withdrawal is large relative to the corpus and the assumed or actual return, the balance can shrink over time and, in this calculator's model, withdrawals stop once the balance reaches zero — the calculator will not show withdrawals continuing past that point. Whether a real investment corpus gets depleted depends on the withdrawal amount, the starting corpus, actual returns achieved, how long withdrawals continue, the withdrawal frequency, and market performance along the way. There's no universal answer to how long a corpus will last — it depends entirely on these factors together, which is exactly why testing your own numbers in the calculator is useful before committing to a withdrawal plan.
It's important to be clear that an SWP from a market-linked investment such as a mutual fund does not guarantee a fixed monthly return, and should not be treated as risk-free or fixed income. You can fix the withdrawal amount you take out, but the value of the underlying investment is not fixed — it moves with the market. A period of poor market performance can reduce the remaining corpus faster than a constant-rate assumption would suggest, and in a bad enough scenario could deplete the corpus sooner than expected. This calculator's single assumed annual rate is a simplification used for illustration and planning, not a forecast of actual market behaviour.
When you're withdrawing money from an investment while it's still exposed to the market, the order in which good and bad years occur can matter, not just the average return over the whole period. Two investment paths can have the exact same average annual return over, say, 10 years, but produce very different remaining corpus values if withdrawals are happening throughout — because withdrawals taken during a downturn permanently reduce the capital that would otherwise have recovered when the market rebounds. This is sometimes called "sequence of returns risk," and it's one reason why a single constant-rate calculator, including this one, is a simplification rather than a precise forecast of a real, fluctuating investment.
Many people explore SWP calculators while thinking about retirement income planning, since regular withdrawals from an accumulated corpus can resemble a monthly paycheck. This calculator can help with that kind of planning by letting you estimate cash-flow needs against a given corpus, test different withdrawal amounts to see their effect on how long a corpus might last, compare different return assumptions, and explore different time horizons. It cannot tell you whether SWP is the right retirement strategy for your specific situation — that depends on your full financial picture, other income sources, health and liquidity needs, and risk tolerance, which are matters for your own judgment or a qualified financial advisor.
Some retirees consider periodic withdrawals from an investment corpus to help meet regular living expenses. Before relying on this approach, it's worth keeping in mind that market-linked returns are uncertain and can vary significantly year to year, the withdrawal amount needs to be sized sensibly relative to the corpus and the income actually needed, taxes and specific product terms can affect the real outcome, and overall suitability depends on individual circumstances including other income, health costs and liquidity needs. This calculator can help model different scenarios, but it is not a substitute for personalized financial or tax advice.
SIP (Systematic Investment Plan) and SWP (Systematic Withdrawal Plan) are, in a sense, opposite cash-flow directions applied to the same kind of underlying investment:
| Feature | SIP | SWP |
|---|---|---|
| Purpose | Building or accumulating a corpus | Withdrawing from an existing corpus |
| Cash flow direction | Money goes into the investment | Money comes out of the investment |
| Typical use case | Long-term accumulation toward a goal | Regular withdrawals, e.g. for income needs |
| Starting requirement | Ability to invest periodically | An existing corpus is generally required |
| Main planning concern | Whether the accumulated corpus meets the goal | Whether withdrawals are sustainable for the corpus |
Neither is universally better — they serve different purposes, and many investors use SIP during their working years to build a corpus, then consider SWP later to draw from it. If you want to model periodic investing instead of withdrawals, ToolPlex's SIP Calculator uses the appropriate formula for that.
A lumpsum investment is a one-time contribution into an investment product, while an SWP is a periodic withdrawal facility applied to an existing investment — the two often sit at different stages of the same overall plan. An investor might, for example, make a lumpsum investment years earlier to build a corpus, and later set up an SWP on that same corpus to draw a regular income from it. If you'd like to estimate how a one-time investment could grow before you start withdrawing from it, ToolPlex's Lumpsum Calculator is built for exactly that.
An SWP from a mutual fund and a Fixed Deposit (FD) behave quite differently. With an SWP, the underlying investment remains linked to the market, so its value can fluctuate, and each withdrawal generally involves redeeming units at the fund's prevailing value. With an FD, the interest rate and maturity terms are fixed by the bank at the time of booking, and premature withdrawal or closure depends on the specific product's terms. Neither is automatically better: an FD offers more certainty with generally lower long-term growth potential, while a market-linked SWP carries more uncertainty alongside the possibility of higher long-term growth. Current FD interest rates vary by bank and tenure and change over time, so check with your bank directly for current, verified figures rather than relying on any figure quoted elsewhere.
Withdrawals made through an SWP from a mutual fund can carry tax implications, and the applicable treatment depends on factors such as the type of fund (for example, equity-oriented versus debt-oriented), how long the redeemed units were held, the gains attributable to those specific units, and the investor's own circumstances. Tax rules relating to mutual fund capital gains have changed over the years and can change again, so this page does not state specific current tax rates. Please check current, official tax rules or consult a qualified tax professional for figures and treatment relevant to your situation — this calculator does not calculate or account for tax.
This calculator provides an illustrative estimate based on the investment amount, withdrawal amount, assumed annual return and tenure entered by the user, applying withdrawals and growth in a fixed monthly sequence. Actual mutual fund and market-linked returns are subject to market risk and may vary significantly from any assumed rate used here; past performance does not guarantee future results. SWP withdrawals may have tax implications depending on the investment product, fund type, holding period and applicable tax rules, which can change — this calculator does not calculate tax. The calculator also does not account for expense ratios, exit loads or other product charges, and does not provide investment, financial or tax advice. Investors should review the applicable product documents and consider their own individual circumstances, or consult a qualified advisor, before making investment decisions.

Use a conservative, realistic return assumption and check how sensitive your remaining corpus is to changes in the withdrawal amount and the return rate. A withdrawal amount that looks comfortable in year one can behave very differently over 10 or 20 years — the year-wise schedule above is the best way to see that for your own numbers.
The withdrawal amount you choose is fixed, but the value of a market-linked investment is not. Actual returns can be higher or lower than any assumption tested in this calculator, and a period of poor market performance can reduce the remaining corpus faster than expected.
