SWP Calculator
Estimate how much monthly income your corpus can support and how long that withdrawal path may last.
What an SWP calculator tells you
An SWP calculator helps you estimate how long a corpus may last once you start taking money out every month. That makes it especially useful for retirement planning, early retirement, or any situation where you want regular income from investments instead of fresh salary.
How to use this SWP calculator
Start with your current corpus, expected annual return, and monthly withdrawal. Then decide whether you want to test a fixed duration or run the plan until the corpus gets exhausted. If you enable inflation, the tool also shows how raising withdrawals over time affects corpus survival.
Why inflation changes withdrawal planning so much
A flat withdrawal may look safe at first, but it slowly buys less every year. Real retirees usually need income to rise over time. That is why an SWP plan that survives comfortably in nominal terms can feel much tighter once inflation is added to the picture.
Use conservative return assumptions for retirement income
Accumulation and withdrawal are not the same game. During the withdrawal phase, bad early years can hurt more because money is leaving the portfolio while markets are moving. A conservative return estimate usually gives you a more useful planning answer than an aggressive one.
