Dependent Care FSA Calculator

A Dependent Care Flexible Spending Account (DCFSA) lets you route pre-tax dollars toward eligible dependent care costs, and the money you set aside never gets taxed. Enter your expected contribution and this tool translates it into a concrete tax-savings figure, which for many households runs into the hundreds or thousands of dollars each year.

The estimate works by applying your combined marginal tax rate, federal, state, and FICA, to the contributions you plan to make. In practical terms, it compares your net income two ways: once with ordinary taxable pay, and once with that same money diverted into the account tax-free. The gap between those two figures is your projected savings.

There is a catch built into the account: DCFSA dollars follow a use-it-or-lose-it rule, so anything left unspent when the year closes is forfeited. That makes a careful estimate of your eligible care expenses the most important input here. Padding your election to be safe tends to backfire, leaving money stranded in the account rather than back in your pocket.
