What is the SWP Calculator?
The SWP Calculator is an online tool that plan systematic withdrawals from your investment corpus during retirement.
What formula does the SWP Calculator use?
Balance each month = (Previous balance − withdrawal) × (1 + monthly return)
How does the SWP Calculator work?
Enter total corpus, monthly withdrawal amount, expected annual return, and see how long funds last or remaining balance.
Formula Used
The equation below is what this calculator applies. Variable definitions follow when symbols are used.
Equation
Balance each month = (Previous balance − withdrawal) × (1 + monthly return)
Additional rules
- runs until corpus depletes or tenure ends
Worked Example: $5,000,000 corpus, $40,000/month withdrawal at 8%
Sample inputs and the results this calculator produces for the scenario below.
Inputs
- Starting Corpus
- $5,000,000
- Monthly Withdrawal
- $40,000
- Expected Return
- 8% p.a.
Results
- Corpus Duration
- ~15–18 years (illustrative)
- Risk
- High withdrawal vs returns depletes faster
SWP sustains income from investments but market returns vary. Keep withdrawals below sustainable yield for longevity.

SWP — Frequently Asked Questions
Each question is answered directly below. Expand any item for the full response.
What does an SWP calculator estimate?
An SWP calculator estimates how regular withdrawals affect the remaining corpus over time while the balance continues to earn returns. It helps answer whether a chosen withdrawal is likely to be sustainable.
Why can the same monthly withdrawal last much longer in one scenario than another?
Sequence of returns matters: poor returns early in withdrawal years damage the corpus more than the same poor returns later. That is why retirees should test conservative return assumptions, not only average long-term returns.
Is an SWP safer than taking random withdrawals?
A planned SWP creates discipline and lets you match withdrawals with a target horizon or income need. It still depends on asset allocation, tax treatment, and whether the withdrawal rate is realistic.
What is a good practical check before relying on SWP income?
See whether the annual withdrawal as a percentage of corpus remains moderate after adjusting for inflation. If the withdrawal need starts very high, the risk of depleting capital rises quickly.
