How is the 401(k) Match Maximizer calculated?

We estimate how much of your employer’s 401(k) match you’re capturing versus leaving behind, and what that gap would grow to by retirement if it went unclaimed each year.

What data and assumptions does it use?

Standard employer-match mechanics and the public-domain future-value-of-an-annuity formula. The growth rate is a shown, configurable assumption.
