How does the Retirement Calculator work?
Your balance compounds monthly: savings × (1 + r)^m plus each monthly contribution compounded to retirement, where r is the annual return ÷ 12 and m is the months until you retire.
Monthly income uses the 4% rule of thumb: withdrawing 4% of the balance in year one, adjusted for inflation, has historically lasted about 30 years. It is a guideline, not a guarantee.
Frequently asked questions
What return should I assume?
Long-run U.S. stock-heavy portfolios have averaged roughly 7% after inflation-adjusted planning, but returns vary widely year to year.
What is the 4% rule?
Withdraw 4% of your portfolio in the first year of retirement, then adjust for inflation. It was designed for roughly 30-year retirements.
Does this include Social Security?
No. Social Security would add to the monthly income shown here.
Is inflation included?
No. Results are in future dollars. Subtract expected inflation from the return to see today's purchasing power.
