What does this HSA contribution calculator estimate?

It combines the IRS annual contribution cap for your tax year and coverage level (self-only vs family), adds the $1,000 catch-up when you indicate age 55 or older by year-end, optionally pro-rates for fewer than 12 eligible months, and subtracts contributions you have already made to show remaining room.

Do I qualify for an HSA?

Generally you need qualifying HDHP coverage and no impermissible coverage (for example, being enrolled in Medicare Part A often disqualifies you; TRICARE and many FSAs also can). Eligibility rules are detailed in IRS Publication 969—this tool does not verify eligibility.

How are the annual limits determined?

The IRS publishes inflation-adjusted limits (Rev. Proc. series). We embed self-only and family caps by tax year; catch-up for age 55+ is an additional $1,000 when eligible.

What is pro-rata for partial-year eligibility?

If you were only eligible part of the year, a common planning shortcut is to multiply the full-year limit by (eligible months ÷ 12). The IRS also has a last-month rule and special exceptions that can change your allowed amount—use professional advice if you had mid-year coverage changes.

Do employer contributions count toward the limit?

Yes. Employer contributions (including salary reduction) generally count toward the same annual contribution limit. Enter total contributions already made including employer amounts in “contributions already made.”

Can both spouses contribute the family limit?

The family limit is shared between spouses with family HDHP coverage; how you split contributions between HSAs has specific rules. Two self-only plans have different math—this calculator models a single coverage selection for one person’s limit illustration.

No. It is for education and estimation. Confirm amounts on IRS forms and with your custodian or tax professional.

How is this different from an FSA?

HSAs are owned by you, roll over year to year when eligible, and have different limits and rules than health FSAs. Use our FSA calculator for flexible spending estimates.

How Our HSA Contribution Calculator Works

We take the IRS annual limit for your selected tax year and coverage level (self-only or family), add the $1,000 catch-up when you indicate age 55 or older by year-end, multiply by eligible months ÷ 12 when you were not covered all year (simplified pro-rata), then subtract contributions already made to estimate remaining contribution room.

Core formulas (illustrative)

Full-year max = base limit + (catch-up if 55+)Pro-rated max ≈ full-year max × (eligible months ÷ 12)Remaining room ≈ max(0, pro-rated max − YTD contributions)

Married couples, mid-year enrollment, the last-month rule, and employer funding can change your actual allowed amount.

Example: family limit, full year

Maximum family contribution

For 2026, family HDHP coverage with 12 eligible months and no prior contributions yields the estimated cap shown—adjust year, coverage, months, and YTD for your case.

Employer contributions reduce the amount you can still contribute directly even when the combined total stays within the cap.
