How the SWP calculator works
A Systematic Withdrawal Plan (SWP) is the opposite of a SIP: instead of adding money every month, you take a fixed amount out while the rest stays invested. This calculator simulates every month:
balance = balance × (1 + annual rate ÷ 12) − monthly withdrawal
When the balance can no longer cover the full withdrawal, the calculator stops and reports the exact duration your money lasts.
The withdrawal-rate rule
Your annual withdrawal rate is (monthly withdrawal × 12) ÷ corpus. If that rate is lower than the return you expect, the corpus grows; if it is higher, the corpus declines. Financial planners often use 4–6% for long retirements — India's higher expected returns sometimes permit the upper end of that range, but taxes and inflation should be factored in.
Inflation-proof withdrawals
A fixed monthly amount buys less every year. Setting the yearly increase to the expected inflation rate (typically 5–7%) keeps real purchasing power constant — at the cost of a shorter corpus life.
SWP versus dividend income
SWPs let you control the amount and timing, and they work with any mutual fund. Dividends depend on the scheme's payout decisions. Many retirees combine an SWP from a hybrid or debt fund with growth assets held for the long run.
