HSA contribution headroom, 2025

This works out one number from the HSA Contribution Limit figures published for 2025. Every amount it uses is below, with the document it was read from. What you enter is your own: this site has no way to check it, and the answer it produces is not a published figure.

Self-only$4,300
Family$8,550

How it is worked out

The published amount less the amount you enter, rounded to the nearest cent. Where what you enter is the larger of the two, the answer is nothing rather than a negative amount.

Your coverage, from the 2 this year publishes: Self-only ($4,300), Family ($8,550). The calculator uses the one you pick and says which.

Figures in this colour are computed from the amounts above. They are not published figures and no document states them.
