Retirement Calculator
Estimate how much you'll need to retire comfortably.
Project your retirement savings against the 4% rule
That target is $1,000,000.00 in today's dollars, inflated at 3%/year to what it'll take in 35 years — compared directly against your projected balance, which is also in future dollars.
To close the gap by age 65, contribute an extra $1,066.51 per month, on top of your current $400.00.
How to use it
- 1Enter your current age, retirement age, and current retirement savings.
- 2Enter your monthly contribution, expected return, and currency.
- 3Enter your desired annual income in retirement, and an expected inflation rate so the target lines up in future dollars.
- 4Read your projected balance against the 4%-rule target, and any extra contribution needed.
Example
A 30-year-old retiring at 65 with $15,000 saved and $400/month contributions at a 7% return builds a projected balance — the chart compares it against the nest egg needed to support a $40,000/year retirement using the 4% withdrawal rule.
How it works
Your current savings and monthly contributions are grown at your expected annual return, compounded monthly, up to your retirement age. Your target nest egg comes from the 4% rule — a widely used guideline that a nest egg of 25 times your desired annual income can sustain that income indefinitely through moderate withdrawals. Since your projected balance is in future dollars, your desired income is grown by the inflation rate you enter over the same years before the 25× target is calculated, so the comparison isn't skewed by leaving one side in today's dollars and the other in tomorrow's.
