Calculate how long your retirement corpus will last given monthly withdrawals and investment returns.
In a drawdown plan your corpus stays invested and you withdraw from it regularly. Each month the remaining balance earns a return, then the withdrawal is taken out. How long the money lasts depends on three things together: the return on the remaining corpus, the size of each withdrawal, and how fast withdrawals rise over time. If withdrawals grow faster than the corpus earns, the balance falls progressively faster. This calculator deducts each withdrawal at the end of the month and steps withdrawals up once a year by the increase you enter. Real returns vary year to year, so treat the result as an estimate, not a guarantee.
Q: How is drawdown different from an annuity?
A: In drawdown you keep the corpus invested and control the withdrawals; the money can run out if withdrawals outpace returns. An annuity is an insurance product where you pay a lumpsum and receive a fixed payout for life or a chosen term, and the insurer carries the risk of your living longer than expected. This page models drawdown, not an annuity payout.
Q: Why does the annual withdrawal increase matter?
A: Prices rise over time, so a fixed monthly withdrawal buys less each year. Raising withdrawals roughly with inflation keeps your spending power steady, but depletes the corpus sooner. Try the calculator with 0% and with your expected inflation to see both ends.
Q: What does "Not exhausted within 50-year simulation" mean?
A: The projection runs up to 50 years. This result means a balance still remains at that 50-year limit for the withdrawals you entered. It is not a guarantee for any specific lifetime, and returns will not stay constant in practice.
Q: What if the money runs out too early?
A: Lower the monthly withdrawal, reduce the annual increase, or start with a larger corpus and compare. The estimate assumes the same return every month; actual returns move around, so keep a margin instead of planning to the exact month.
