What is the Monthly Retirement Income Calculator?
This retirement income calculator converts a lump-sum corpus into a steady monthly payout by deliberately drawing the corpus down to zero by the end of a chosen retirement period — a different approach from the safe withdrawal rate calculator, which preserves the corpus indefinitely by withdrawing only a sustainable percentage, and from an annuity, which is an insurer-backed product offering a guaranteed income for life rather than a self-managed drawdown.
How to Calculate
Enter your corpus size, the return you expect it to keep earning during retirement, and the number of years you want it to last. The calculator uses an annuity-style formula to find the level monthly withdrawal that exactly exhausts the corpus — growing at your assumed return — by the end of that period.
Formula
Income = Corpus × i ÷ (1 − (1 + i)^−months)
