Always Capture the Full Employer Match
Employer matching is often described as "free money" for good reason — this calculator assumes your employer matches a flat percentage of your salary as long as you contribute at least that much yourself. Contributing less than your employer's match threshold means leaving part of your compensation on the table.
Why Starting Early Has an Outsized Effect
Because 401(k) growth compounds for decades, the same contribution made in your 20s typically ends up worth far more at retirement than an identical contribution made in your 40s — try lowering the current age above to see the difference.
Comparing Traditional vs Roth Contributions
This calculator doesn't distinguish between pre-tax (traditional) and after-tax (Roth) 401(k) contributions — see the Roth IRA calculator for a look at how tax treatment affects your effective retirement savings.
Frequently Asked Questions
Should I contribute enough to get the full employer match?
Yes, in almost every case — an employer match is an immediate, guaranteed return on your contribution that is very hard to beat elsewhere.
Does this account for salary raises over time?
No, this calculator assumes a flat salary for simplicity. Rising income over your career would increase both your contributions and employer match beyond this estimate.
