How Much Will Your 401(k) Be Worth?
Project a 401(k) balance using your current balance, annual contributions, employer match, return assumption, and time horizon.
401(k) growth scenario
This is a constant-return projection, not a market forecast. Inputs stay in your browser.
Projected balance
$1,703,064
After 30 years
Starting balance + contributions
$470,000
Does not include investment growth
Projected growth
$1,233,064
Difference created by the return assumption
At a 7% annual return, the model grows $14,000 of annual contributions and adds them at the end of each year.
What this projection means
The projection shows the effect of steady contributions under one constant return assumption. Actual investments fluctuate, fees reduce returns, contributions can change, and inflation reduces purchasing power.
How to use it responsibly
Run multiple scenarios instead of treating one result as a promise. Compare a lower-return case, a higher-contribution case, and the effect of capturing your full employer match.
