How the projection works
Existing savings grow at the annual rate. Monthly contributions compound at the monthly rate. Both totals add up to the retirement balance.

How to use Retirement Calculator
Enter your current age, target retirement age, existing savings, monthly contribution amount, and expected annual return rate. The Retirement Calculator shows your projected balance at retirement, total contributed, and total interest earned.
The default 7% return reflects the historical average of broad stock market index funds. Adjust to match your actual investment mix.
The 7% return assumption
The S&P 500 has historically averaged 7–10% annually after inflation. 7% is a conservative estimate used for long-term planning.
Starting earlier matters enormously
A 25-year-old saving $300/month at 7% will have nearly twice as much at retirement as someone starting at 35 with the same monthly contribution.

What is the 4% rule?
The 4% rule suggests you can safely withdraw 4% of your retirement balance each year without running out of money over 30 years.
What annual return should I use?
7% is a common conservative estimate for long-term stock market returns. Bonds return 3–5%. A blended portfolio might use 5–6%.

A common target is 25x your expected annual expenses (based on the 4% rule). This calculator helps you project whether you will reach that number.
Does this include Social Security or pension?
