Managing healthcare and dependent care expenses can be challenging, especially when trying to understand how much money you’re actually saving through employer benefits. A Flexible Spending Account (FSA) calculator helps you clearly estimate your tax savings, paycheck deductions, and real out-of-pocket costs—before you commit to a contribution amount.

Our free FSA Calculator is designed to give you quick, accurate insights into how your annual FSA contribution affects your finances. Whether you’re enrolling in benefits for the first time or reevaluating your contribution during open enrollment, this tool helps you make confident, informed decisions.

What Is an FSA and Why Does It Matter?

A Flexible Spending Account (FSA) is a tax-advantaged account offered by many employers that allows you to set aside pre-tax income for qualified expenses, such as:

  • Medical and dental expenses
  • Vision care
  • Prescription medications
  • Dependent care (for eligible plans)

Because FSA contributions are deducted from your income before taxes, you reduce your taxable income and keep more of your money.

However, deciding how much to contribute can be confusing. Contribute too little, and you miss out on savings. Contribute too much, and you risk unused funds. That’s where an FSA calculator becomes essential.

What the FSA Calculator Helps You Determine

This calculator provides a clear breakdown of how your FSA contribution impacts your finances. It calculates:

  • Annual tax savings based on your tax rate
  • Monthly FSA contribution amount
  • Per paycheck deduction based on pay frequency
  • Effective after-tax cost of your contribution

These insights help you understand not just what you contribute—but what it actually costs you after tax savings.

How to Use the FSA Calculator

Using the calculator is simple and takes less than a minute. Follow these steps:

1. Enter Your Annual Income

Input your total yearly income before taxes. This helps provide context, although the calculation focuses on your contribution and tax rate.

2. Enter Your Annual FSA Contribution

This is the amount you plan to contribute to your FSA for the year. You can adjust this number to compare different scenarios.

3. Enter Your Marginal Tax Rate

Add your estimated marginal tax rate as a percentage. This is crucial for calculating your tax savings accurately.

4. Enter Pay Periods Per Year

Specify how often you are paid (for example, 12 for monthly, 24 for semi-monthly, or 26 for bi-weekly).

5. Click “Calculate”

The calculator instantly displays your results, showing how your contribution is divided and how much you save.

6. Reset to Try Another Scenario

Use the reset option to test different contribution amounts or tax rates.

Example: Understanding Your FSA Savings

Let’s walk through a realistic example:

Scenario:

  • Annual Income: $60,000
  • Annual FSA Contribution: $2,400
  • Marginal Tax Rate: 22%
  • Pay Periods: 24

Results:

  • Annual Tax Savings: $528
  • Monthly Contribution: $200
  • Per Paycheck Contribution: $100
  • Effective After-Tax Cost: $1,872

What This Means

Although you contribute $2,400 to your FSA, it only costs you $1,872 after tax savings. That’s money you would have spent anyway on healthcare—now at a discount.
