Retirement Calculator
Two phases: accumulation while you work, then drawdown in retirement as spending rises with inflation and other income offsets it.

A simplified projection — returns are averaged, not sequenced.
How it works
Contributions grow at the pre-retirement return to your retirement age. Then each year's inflation-adjusted spending, less other income, is withdrawn while the balance earns the post-retirement return.
Explain it to a kid
Retirement means saving money now — even a little at a time — so that when you're all grown up and done working, you already have a big pile saved to live on. It's like packing snacks for a really, really long hike that doesn't start for many, many years.
Frequently asked questions
How does the accumulation phase work?
Your current savings and monthly contributions grow every month at the pre-retirement return you enter, compounding until your retirement age — the same mechanics as the compound interest calculator.
How is retirement spending handled?
Your entered annual spending (in today's dollars) is inflated forward to your retirement age and then increases with inflation every year after that, so the withdrawal keeps pace with rising costs rather than staying flat in nominal terms.
What does 'other income' offset?
Social Security, a pension, or any other income you expect in retirement reduces how much you need to withdraw from savings each year — enter it in today's dollars and it inflates the same way your spending does.
What if the calculator shows my money running out?
It reports the age your balance hits zero under your current assumptions. Common levers to fix a shortfall are saving more before retirement, retiring later, spending less in retirement, or adjusting the expected return — try a few combinations to see what closes the gap.
