Small changes in the expected annual return compound into large differences over decades. A 7% versus 8% assumption over 30 years can mean a difference of tens of thousands of dollars in the final balance — try adjusting the rate above to see the sensitivity for yourself.
Inflation, taxes on withdrawal, employer matching contributions, and fees aren't factored in separately — build those into your contribution or return assumptions if you want to account for them.
Many long-term planners use 6-8% for diversified stock-heavy portfolios, based on long-run historical averages, though future returns aren't guaranteed and vary by asset allocation. Conservative planners often use a lower number to be cautious.
This calculator shows nominal (non-inflation-adjusted) dollars. To estimate purchasing power in today's dollars, you can lower the return rate by your assumed inflation rate — for example, using a 4-5% "real" return instead of 7-8% nominal.
A common guideline is 15% of gross income toward retirement, including any employer match. Your actual number depends on your target retirement age, expenses, and other savings goals.
