About the Retirement Calculator
The retirement calculator estimates the size of your retirement savings at the age you plan to stop working, based on what you have saved so far, what you add each month and an assumed annual return. It then applies the widely cited 4% rule to estimate how much you could withdraw in the first year of retirement. A chart shows the balance growing year by year. The figures are before tax and in future dollars, and the 4% rule is a rule of thumb from historical U.S. market data rather than a guarantee, so use the result as a planning benchmark to compare against your expected spending.
How to use it
- 1Enter your current age and the age you plan to retire.
- 2Enter the amount you have already saved for retirement.
- 3Enter your monthly contribution, including any employer match.
- 4Enter an expected annual return as a percentage.
- 5Press Calculate to see your projected balance and an estimated first-year withdrawal.
Worked example
a 30-year-old with $25,000 saved who adds $600 a month until age 65 at a 7% return reaches about $1,368,000. Total contributions are $277,000; the rest is investment growth. Under the 4% rule that balance supports a first-year withdrawal of about $54,700.
How it works
How it works
Your current savings and monthly contributions grow with compound returns until retirement. The 4% rule estimates sustainable annual withdrawals.
Who it is for
Workers planning retirement contributions, people checking whether they are on track, and anyone weighing an earlier or later retirement age.
Why it helps
Turning a distant goal into a single projected number makes it easier to decide whether to save more, work longer or adjust expectations.
Common use cases
- Checking whether current contributions are enough
- Comparing retirement at 60, 65 and 67
- Seeing the effect of increasing contributions by $100 a month
- Estimating a sustainable first-year withdrawal
