FSA Contribution Limit Calculator

What Is the FSA Contribution Limit Calculator?

This tool checks your planned annual healthcare Flexible Spending Account contribution against the 2026 IRS limit of $3,400, flagging whether you're within or over that limit. Remember FSA funds are generally "use it or lose it" each plan year (unless your employer's plan allows a limited carryover or grace period) -- factor that into how much you plan to set aside.

How to Use This Tool

Enter your planned annual FSA contribution. The tool shows the current limit and whether your planned amount fits within it.

What the Checker Shows

You enter the amount you plan to contribute for the year. The tool compares it with the built-in healthcare FSA limit and shows the limit, the room remaining, and a flag if your planned amount exceeds it. If you plan 2,000, the remaining room is the limit minus 2,000. If you plan more than the limit, the remaining room appears as a negative number, which is the amount over. There is no age or coverage input because the individual healthcare FSA limit does not depend on them.

Worked Example With Hypothetical Numbers

Suppose you are choosing an election during open enrollment and expect the following costs: a dental cleaning schedule, new glasses, a couple of prescriptions and a few copays. If you total those at about 1,800 for the year, entering 1,800 shows well within the limit. A parent planning orthodontics might estimate 4,000, and entering that would flag the amount as over the limit by the difference. That signals you either need to plan for a smaller election, or, in some plans and situations, a spouse's separate plan may offer its own election.

How to Pick an Amount

• Start from past receipts: total your out-of-pocket eligible medical, dental and vision expenses from the last year.
• Add known upcoming costs such as a planned procedure or recurring prescription.
• Choose a number you are confident you will spend. Because unused money may be forfeited under many plans, underestimating is usually less painful than overestimating.
• Check what your plan allows: a carryover, a grace period, or neither. Rules differ by employer.

Important Things the Tool Does Not Track

The limit applies to your own salary reduction election, and a plan can set a lower ceiling than the federal one. Your employer might also contribute, and some types of FSA, such as dependent care accounts or limited-purpose accounts paired with an HSA, follow different rules. This tool only checks the general healthcare FSA limit. It also does not verify which expenses are eligible; your plan administrator or the IRS eligible expense lists are the place to check. Mid-year changes to your election are only allowed after a qualifying life event, so plan carefully during enrollment.

Interaction With an HSA

If you have an HSA, a general-purpose healthcare FSA can interfere with your eligibility to contribute to it. A limited-purpose FSA, covering things like dental and vision, is generally the version that works alongside an HSA. Ask your benefits team which type is offered before you elect.

Common Mistakes

• Electing a large amount for expenses that may not be eligible.
• Forgetting the deadline to incur expenses and submit claims.
• Assuming the balance will be available in full only after you have contributed. Many plans make the full annual election available early, but confirm your plan rules.
• Treating the federal figure as your plan cap when the plan may set a lower one.
