<h1>SWP calculator models withdrawals to estimate corpus longevity, compare scenarios, and highlight tax, inflation and market risks.</h1> An SWP calculator models periodic withdrawals using inputs such as initial corpus, withdrawal amount and frequency, assumed rate of return, time horizon and optional inflation adjustment to project corpus longevity and balance trajectories. Users should run multiple scenarios, consider fixed versus inflation indexed withdrawals, and account for taxes and fund charges. The tool is an aid, not a prediction; mutual fund investments are subject to market risks and periodic review is recommended.
