Withdrawal calculator
With $300,000, withdrawing $1,500 a month and earning 4% a year, the money lasts 27 years and 5 months. The calculator shows this for your own numbers, also with a withdrawal that rises every year.
How it is calculated
Month by month: the withdrawal is taken at the start of the month, then the rest grows by return ÷ 12. If the withdrawal rises, it increases by the given rate every year. The constant monthly withdrawal for a fixed period is K · i ÷ ((1 − (1 + i)−n) · (1 + i)), with i = return ÷ 12 and n = months.
Frequently asked questions
What return should I assume?
That is your assumption. Past returns say nothing about the future, and fluctuating returns can change the result a lot – especially losses in the first years.
What does “withdrawal rises per year” mean?
To keep its purchasing power, the withdrawal can rise with inflation every year. That shortens how long the money lasts.
Are taxes and costs included?
No. The calculator shows the plain arithmetic.
