401(k) Calculator With Employer Match
Your projected balance including every dollar of employer match, and a warning if you are not contributing enough to capture it.
Projected 401(k) balance
The match is an instant 50% return on your own deferral, before any market growth. No investment offers a comparable guaranteed return, which is why capturing the full match generally comes before every other savings or debt priority except emergency cash.
Employer matches are usually written as a rate up to a limit: 50% of your contributions up to 6% of salary, for example. That caps the employer’s contribution at 3% of salary no matter how much more you defer. Contributing less than the limit leaves part of that match unclaimed, which this calculator flags directly.
Frequently asked questions
How much should I contribute to my 401(k)?
At minimum, enough to capture the entire employer match, since anything less forfeits guaranteed money. Beyond that, many planners suggest 15% of gross income including the match, adjusted for your timeline and other savings.
What is vesting?
Employer contributions often require you to stay a certain number of years before they are fully yours. Cliff vesting grants everything at once after a set period; graded vesting releases it in increments. Your own contributions are always immediately yours.
Traditional or Roth 401(k)?
Traditional contributions reduce taxable income now and are taxed at withdrawal; Roth contributions are taxed now and grow tax free. Traditional tends to favor those in a high bracket today, Roth those expecting higher rates later, and splitting between them hedges the uncertainty.
What happens to my 401(k) if I leave?
You can leave it with the old plan, roll it into a new employer plan, or roll it into an IRA. A direct rollover avoids withholding and penalties. Cashing out before 59 and a half generally triggers income tax plus a 10% penalty.
