A Systematic Withdrawal Plan (SWP) calculator helps investors plan regular withdrawals from their investments while estimating how long the funds will last, considering a chosen monthly withdrawal amount and expected annual return rate. By entering the investment amount, monthly withdrawal, and anticipated returns, users can better manage cash flows and avoid outliving their savings. This tool is especially useful for retirees or anyone relying on periodic income from mutual funds or fixed deposits, offering clarity and control over their long-term financial planning. It combines convenience, customization, and visual appeal for easy use and quick insights.
