How to use this calculator
- Enter your savings at the start of retirement.
- Enter the monthly amount you plan to withdraw, and how much it rises each year.
- Enter the return you expect on what stays invested, and the number of years.
Withdrawals are taken at the start of each month and the rest grows monthly: with these defaults, $422,415 is left after 30 years.
Frequently asked questions
How much can I safely withdraw each month?
It depends on your returns, how long retirement lasts and how much you raise withdrawals for inflation. The calculator shows two useful limits: the most you can take without touching your principal, and the starting amount that would use up the balance exactly at the end of the period.
What is the 4% rule?
A rule of thumb: withdraw about 4% of your savings in the first year, then raise the dollar amount with inflation. Here, $4,000 a month from $1,000,000 is a 4.8% first-year withdrawal rate. It’s a starting point, not a guarantee — the Retirement Calculator replays real market history.
What if returns are lower than expected?
At 4% instead of 6%, the same plan runs out after 23 years 11 months. A cautious return is worth testing before you commit to a withdrawal amount.
Are taxes included?
No. Withdrawals from traditional 401(k)s and IRAs are generally taxable income; Roth withdrawals and taxable accounts are treated differently. Figures here are before tax.
