403(b) contribution planner, 2025

This works out one number from the 403(b) 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.

How it is worked out

The published base limit, plus the published catch-up amount if you are eligible for it, less what you enter as contributed so far. Both published amounts are exact, so only your own figure is rounded, to the nearest cent. Where you have already contributed more than the limit allows, the answer is nothing rather than a negative amount.

It uses Elective deferral limit, $23,500 and Catch-up limit, age 50 and over, +$7,500, published above.

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