How the FSA Contribution Calculator Works
Inputs:
- Estimated annual qualified expenses
- Annual salary (for tax impact)

Formula Used in This Calculator
1. Tax Savings = FSA Contribution × Total Tax Rate
2. Total Tax Rate = Federal Tax + FICA + State Tax
3. Remaining Expenses = Estimated Expenses – FSA Contribution
Note: The IRS limits for 2025 are:
Healthcare FSA: $3,200 | Dependent Care FSA: $5,000 (household)
Example Calculation
Assume:
- Estimated Medical Expenses: $2,500
- Annual Salary: $70,000
- Federal Tax Rate: 22%
- FICA: 7.65%
- State Tax: 5%
Total Tax Rate = 22% + 7.65% + 5% = 34.65%
Recommended FSA Contribution = $2,500
Tax Savings = $2,500 × 34.65% = $866.25
So, by contributing $2,500 to your FSA, you save $866.25 in taxes and cover your expected healthcare costs.
