A Health Savings Account (HSA) is the only account with a triple tax advantage: contributions go in pre-tax, the money grows tax-free, and withdrawals for qualified medical expenses are tax-free too. Unlike an FSA, HSA balances roll over every year and can be invested, which makes the HSA a powerful long-term and even retirement savings vehicle. This calculator shows both sides of that value — the tax you save this year by contributing pre-tax dollars, and the tax-free balance your HSA could grow to by retirement — using the current IRS limits, your tax bracket, and an expected rate of return.
An HSA is a tax-advantaged account available to people enrolled in a qualifying high-deductible health plan (HDHP). For 2026, you can contribute up to $4,400 with self-only coverage or $8,750 with family coverage, plus a $1,000 catch-up if you are 55 or older. To be HSA-eligible in 2026, your HDHP must have a deductible of at least $1,700 (self-only) or $3,400 (family). Unlike a Flexible Spending Account (FSA), HSA funds never expire, stay with you if you change jobs, and can be invested — so many people pay current medical costs out of pocket and let the HSA grow tax-free for retirement.

Weigh the tax impact of an HSA against a flexible spending account before choosing.
Quantify the deduction and tax savings from maxing out your HSA for the year.
See both your immediate tax savings and the tax-free balance your HSA could grow to by retirement — most calculators show only one.
Pre-tax contributions, tax-free growth, and tax-free qualified withdrawals — the calculator turns that into real dollars for your situation.
Only HSA contributions made through payroll avoid the 7.65% FICA tax; direct contributions are deductible but not FICA-exempt. We model both correctly.
If you're 55 or older, the calculator automatically adds the $1,000 catch-up contribution to your limit.
The 2026 IRS limits are applied automatically, and the calculator flags you if a contribution exceeds the cap.
Your income and filing status set your marginal federal rate, so the federal portion of the savings is accurate rather than a flat guess.
An HSA is a tax-advantaged savings account for people with a qualifying high-deductible health plan (HDHP). It has a triple tax advantage: contributions are pre-tax, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. Unlike an FSA, the balance rolls over indefinitely and can be invested.
For 2026, the HSA contribution limit is $4,400 for self-only coverage and $8,750 for family coverage. People 55 and older can contribute an extra $1,000 catch-up. To qualify, your HDHP must have a minimum deductible of $1,700 (self-only) or $3,400 (family) in 2026.
If you are 55 or older and not enrolled in Medicare, you can contribute an additional $1,000 per year on top of the standard limit. This calculator adds the catch-up automatically when your age is 55 or more. Spouses who are both 55+ each need their own HSA to make two catch-up contributions.
Your immediate saving equals your contribution times your combined tax rate (marginal federal rate + 7.65% FICA for payroll contributions + state rate). Maxing a $4,400 self-only HSA at a 22% federal bracket, 7.65% FICA, and 5% state saves about $1,525 in the first year — before any of the tax-free growth.
Not quite. Contributions made through your employer's payroll (a Section 125 cafeteria plan) avoid federal income tax, state income tax, and the 7.65% FICA tax. Contributions you make directly are deductible from income tax (on Form 8889) but do not avoid FICA. Use the contribution-method toggle to see the difference.
An HSA requires an HDHP, but the balance rolls over every year, is yours to keep if you change jobs, and can be invested. An FSA has no health-plan requirement and is open to most employees, but it is largely use-it-or-lose-it and tied to your employer. The HSA is the stronger long-term and retirement vehicle; use our FSA calculator to compare.
Yes. Most HSA providers let you invest the balance once it passes a threshold, and the growth is tax-free. Many savers pay current medical bills out of pocket and let the HSA compound for decades. After age 65 you can withdraw for any purpose paying only income tax (like a traditional IRA), while medical withdrawals stay tax-free.
A high-deductible health plan (HDHP) is one whose deductible meets the IRS minimum — $1,700 self-only or $3,400 family in 2026 — and whose out-of-pocket maximum is within the IRS cap. You're HSA-eligible if you're covered by an HDHP, have no other disqualifying coverage, and aren't enrolled in Medicare or claimed as a dependent.
