How to use the retirement income calculator

  1. Enter your savings at retirement.
  2. Add how much you plan to withdraw each month.
  3. Set your expected yearly return and inflation. Withdrawals rise with inflation every year.
  4. Choose how many years you want the money to last to see a sustainable monthly amount.

How it's calculated

The calculator runs month by month: the balance grows by the monthly return, then your withdrawal is taken out. Once a year the withdrawal rises by inflation. It counts how many months pass before the balance reaches zero.

The sustainable amount is the starting monthly withdrawal that brings the balance to zero exactly at the end of the period you choose.

Example

With $800,000 saved, withdrawing $4,000 a month (rising 2.5% a year with inflation) and earning 5% a year, the money would last about 22 years and 1 month. To make it last exactly 30 years, you could start at about $3,213 a month.

Tips

  • Withdrawing about 3–5% of your savings in the first year is the range many experts suggest.
  • Being flexible, spending a little less after a bad market year, helps savings last longer.
  • Add Social Security and other income before deciding how much you need to withdraw.
  • Plan for a long life. Retirement can last 30 years or more.

Frequently asked questions

How long will my retirement savings last?
It depends on your balance, how much you withdraw, your return and inflation. The calculator combines all four; try higher inflation or lower returns to stress-test your plan.
What is a safe withdrawal rate?
Many experts suggest starting in the 3–5% range of your savings in the first year and adjusting for inflation after that. Withdrawing conservatively early in retirement leaves more room for bad years.
Why do withdrawals rise each year?
Prices rise over time, so the same lifestyle costs more each year. Raising withdrawals with inflation keeps your spending power steady.
Does this include Social Security?
No. Enter only what you'll take from savings. Subtract Social Security, pensions or other income from your monthly spending first.
