SWP Calculator — How Long Will Your Corpus Last?

Withdraw a fixed amount monthly from your corpus and see the balance over time and how long the money lasts.

Formula

Each month the balance grows at the periodic rate i = r/12, then the fixed withdrawal W is subtracted: balance ← balance × (1+i) − W. Simulated month by month until the period ends or the corpus reaches zero.

Frequently Asked Questions

What is an SWP?

A Systematic Withdrawal Plan is the mirror of a SIP: you invest a lump sum (usually in a mutual fund) and withdraw a fixed amount every month while the rest stays invested and keeps earning.

What withdrawal rate is safe?

A common rule of thumb is the 4% rule — withdrawing about 4% of the corpus per year, adjusted for inflation. If your monthly withdrawal is below the monthly growth (corpus × rate ÷ 12), the corpus never depletes in this model.

Does this account for taxes and market ups and downs?

No — this is a constant-return estimate. Real returns vary year to year and withdrawals may be taxed. Treat the result as a planning figure, not a guarantee.
