How much can I save with an HSA or FSA?
This HSA vs FSA tax savings calculator estimates how much your contributions reduce taxes and what the net cost really is.
Try the calculator
Compare HSA and FSA savings with your marginal tax rates.
How it works
We multiply your annual contribution by your combined tax rate (federal, state, and payroll if applicable) to estimate savings.
Example scenario
A $3,000 contribution with a 30% combined tax rate can reduce taxes by about $900, making the net cost around $2,100.
What this means
HSAs and FSAs reduce taxable income and can make healthcare expenses feel smaller. Use the net cost to plan monthly budgets.
FAQ
Does an HSA reduce payroll taxes?
Often yes if contributions are made through payroll, but rules vary. Use the payroll tax toggle to match your situation.
What happens if I do not use FSA funds?
Many FSAs have “use-it-or-lose-it” rules with limited carryover. Check your plan details.
Which account is better?
HSAs are more flexible long term if you are eligible. FSAs can still be valuable for expected expenses.
