Your 401(k) is likely your largest retirement asset — and employer matching is free money you shouldn't leave on the table. But how much will it actually be worth at retirement?

This calculator projects your 401(k) balance over time, factoring in your contributions, employer match percentage, match cap, annual contribution limits, and expected investment returns. See the dramatic difference between contributing just enough for the match versus maxing out.

Use it to decide how much to contribute, understand the impact of starting early versus late, and set a realistic retirement savings target.
