FSA Savings Scenario Calculator
Estimate federal tax savings from your own elected FSA contribution and marginal tax rate.
What this answers:
- Given an elected FSA contribution and marginal tax rate, what's the estimated federal tax savings?
Enter your own elected contribution — this tool does not suggest or assume a plan limit, since current-year FSA limits and eligibility rules should be verified with your plan administrator or a tax professional. This is not a tax filing calculation.

How it's calculated
estimated savings = elected contribution × marginal tax rate
Worked example
$2,000 contribution at 22%: $440 estimated savings.
What this estimate does and doesn't cover
An FSA (Flexible Spending Account) lets you set aside pre-tax pay for eligible health expenses, so the dollars you contribute aren't taxed at your marginal federal income tax rate. This calculator applies only that federal-income-tax arithmetic to the numbers you enter — it does not include potential FICA payroll-tax savings, state income tax, or any other part of your actual tax return, and it does not assume or suggest a contribution limit for you.
Before you rely on this
Verify your plan's actual contribution limit, eligible-expense rules, and any "use it or lose it" or grace-period/carryover terms with your plan administrator — these vary by employer and by year. The IRS's Publication 969 (Health Savings Accounts and Other Tax-Favored Health Plans) covers the federal rules for FSAs generally; it is not a substitute for your specific plan documents.
