SWP calculator for fixed monthly withdrawals
A systematic withdrawal plan, or SWP, is a way to take money out of an investment at regular intervals. In India, the term is often used for scheduled mutual fund redemptions. In other countries, similar arrangements may be called regular withdrawals or investment drawdown.
This calculator estimates monthly payouts and the remaining investment balance. Enter your starting savings, withdrawal amount, expected annual return and plan duration. The planned monthly withdrawal stays fixed throughout the selected period.
How to use the SWP calculator
- Choose a currency. The math is the same for every currency. Choosing USD, INR, EUR or another currency changes display labels, not exchange rates.
- Enter your starting investment and monthly withdrawal. Both amounts appear in English words as you type. Use lakh/crore or international number formatting.
- Set a duration and return assumption. Try a lower return as well as your main estimate.
- Choose the start date and timing. Set whether withdrawals happen at the beginning or end of each monthly period.
- Review funding and download. See the remaining balance, actual withdrawals and any shortfall. Save a PDF, export the yearly table as CSV or download the chart.
How are SWP withdrawals calculated?
The calculator follows the balance one monthly period at a time. Under the default end-of-period setting, it applies the monthly return first, then pays the withdrawal:
Actual withdrawal = smaller of planned withdrawal and available balance
Closing balance = available balance − actual withdrawal
With beginning-of-period withdrawals, the payment comes out first and the monthly return applies to what remains. A monthly period starts on your chosen plan date; later dates use the same day of the month, clamped to month-end when needed. For example, one month after 31 January is 28 February, or 29 February in a leap year.
The default monthly rate is the annual percentage divided by 100 and then by 12. The effective annual option uses (1 + annual rate)1/12 − 1. These methods are different: 12% divided by 12 gives 1% per month, while a 12% effective annual return gives about 0.9489% per month.
The model keeps unrounded internal amounts and displays two decimals. It never pays more than the available balance and never allows the balance to go below zero. After depletion, later planned withdrawals count as unfunded.
Fixed monthly withdrawals
Your planned withdrawal stays the same each month. A monthly withdrawal of 1,000 means planned withdrawals of 12,000 per year and 60,000 over five years.
Actual payouts depend on the available balance. If savings run out, the final payment may be smaller, and later planned withdrawals are shown as unfunded. All displayed amounts are nominal amounts in your selected currency.
A simple SWP example
Start with 100,000, withdraw 1,000 at the end of each monthly period, assume 6% annual return divided by 12, and keep withdrawals fixed for 5 years.
| Starting investment | 100,000 |
|---|---|
| Total actual withdrawals | 60,000 |
| Estimated closing balance | 65,115 |
| Estimated investment gain | 25,115 |
The gain equals closing balance plus actual withdrawals minus the starting investment. The 60,000 withdrawn is not all profit: payouts can include your original capital.
What happens when the money runs out?
The calculator identifies the monthly payment that exhausts the balance. If only part of a planned withdrawal is available, it pays that amount and records the rest as unfunded. The message shows how many full withdrawals were supported and gives the exhaustion payment date.
For example, at 0% return, a balance of 2,500 supports two full withdrawals of 1,000 and a final partial withdrawal of 500 in month 3. A balance of 3,000 supports exactly three full withdrawals of 1,000. Both balances are exhausted at payment 3, but the payouts differ.
If the balance remains positive at the end, the result says it lasts beyond the selected period. It does not claim that the money lasts forever.
Understand the limits of the projection
Actual returns change over time. Losses early in a withdrawal plan can cause more damage than the same losses later, because withdrawals leave less capital to recover. This is often called sequence-of-returns risk. The smooth chart here assumes a constant return and does not measure that risk. Read more in NISM's guide to retirement planning risks.
Taxes, transaction charges, exit loads and ongoing fees depend on your investment, account and country. They are not included. This calculator does not identify a universally safe withdrawal amount or recommend a financial product. Its results are educational estimates, not personalized investment advice.
FAQ on Calculator
No. Withdrawals may include both investment gains and a return of your original capital. The separate gain or loss result tracks the modeled investment performance.
No. The funding result depends on constant-return assumptions. Actual returns, taxes and expenses can change the outcome.
Yes. This calculator uses a fixed monthly withdrawal throughout your plan. Only the final payout may be smaller if the available balance is insufficient.
Yes. A 0% return uses savings only to pay withdrawals. A negative return also reduces the balance through investment losses.
