Calculate HSA growth and tax savings.
The HSA Calculator helps you maximize the most powerful tax-advantaged account available in the U.S. tax code. A Health Savings Account (HSA) is the only account offering a triple tax advantage: tax-deductible contributions, tax-free investment growth, and tax-free withdrawals for qualified medical expenses. No 401(k), IRA, or other account matches this benefit.
Whether you're building a medical emergency fund, planning for healthcare costs in retirement, or using your HSA as a "stealth IRA" for long-term wealth building, this calculator shows you exactly how your contributions grow over time and quantifies your annual tax savings. The average American spends over $315,000 on healthcare in retirement—your HSA can help you prepare tax-efficiently.
Example: $4,300 contribution × (22% federal + 5% state + 7.65% FICA) = $1,489 annual tax savings
Future Value Formula: FV = Σ [(Balance + Annual Contribution) × (1 + Return Rate)^Years]
HSA contributions made through payroll deduction also avoid FICA taxes (7.65%), which 401(k) contributions do not—a hidden advantage worth up to $654/year for family coverage.
IRS HSA limits have increased steadily to keep pace with healthcare cost inflation:
| Year | Individual Limit | Family Limit | Catch-up (55+) | Max Family w/ Catch-up |
|---|---|---|---|---|
| 2022 | $3,650 | $7,300 | +$1,000 | $8,300 |
| 2023 | $3,850 | $7,750 | +$1,000 | $8,750 |
| 2024 | $4,150 | $8,300 | +$1,000 | $9,300 |
| 2025 | $4,300 | $8,550 | +$1,000 | $9,550 |
| 2026 | $4,300 | $8,550 | +$1,000 | $9,550 |

Qualified medical expenses for tax-free HSA withdrawals include (per IRS Publication 502):
Medical & Healthcare:
Dental & Vision:
Over-the-Counter (since 2020):
Other Qualified Expenses:
❌ Mistake: Not investing your HSA funds. Over 80% of HSA dollars sit in cash earning near 0%. If you can cover current medical expenses from your budget, invest your HSA for long-term growth. A $4,300 annual contribution invested at 7% for 25 years grows to $290,000 vs. $107,500 in cash.
❌ Mistake: Using HSA for current expenses when you can afford to pay cash. The optimal strategy for wealth building: pay current medical bills from your regular budget, invest 100% of HSA contributions, and let them grow tax-free for decades. You can reimburse yourself later—even years later—for any documented medical expense.
❌ Mistake: Not keeping medical receipts. Keep all medical receipts indefinitely. You can reimburse yourself from your HSA at any time for expenses incurred after opening the account—even 20 years later. This lets your investments grow tax-free while still accessing the funds eventually.
❌ Mistake: Withdrawing for non-medical expenses before age 65. You'll pay income tax PLUS a 20% penalty. A $1,000 non-qualified withdrawal in the 22% bracket costs $420. Wait until 65 when the penalty disappears.
❌ Mistake: Contributing without HDHP coverage. You can only contribute during months you have qualifying HDHP coverage. Contributing when ineligible triggers a 6% excess contribution penalty each year until corrected.
❌ Mistake: Forgetting employer contributions count toward limits. If your employer contributes $500 to your HSA, your personal contribution limit decreases by $500. Exceeding total limits results in a 6% penalty.
Understanding the key differences helps you choose the right account (or use both strategically):
| Feature | HSA | FSA |
|---|---|---|
| Eligibility | Must have HDHP | Any employer health plan |
| 2026 Contribution Limit | $4,300 individual / $8,550 family | $3,200 (2025 limit; 2026 TBD) |
| Rollover | 100% rolls over forever | Use-it-or-lose-it (max $640 rollover) |
| Investment Option | Yes—stocks, bonds, mutual funds | No—cash only |
| Portability | Yours forever, even if you leave job | Lost when leaving employer |
| Tax Treatment | Triple tax-free (deduction + growth + withdrawals) | Pre-tax contributions only |
| Retirement Use | After 65: any purpose (taxed as income) | Medical expenses only, no retirement benefit |
| Best For | Long-term savings, investors, those who can pay medical bills from budget | Predictable annual medical expenses, lower deductible plans |
Note: You can have both a Limited-Purpose FSA (dental/vision only) AND an HSA simultaneously if your employer offers it.
Sources & Methodology: HSA contribution limits and eligibility requirements per IRS Publication 969 (Health Savings Accounts and Other Tax-Favored Health Plans) and annual Revenue Procedures. HDHP minimum deductible and out-of-pocket maximums per IRS guidelines. FSA limits per IRS Publication 15-B. Future value calculations use standard compound growth formulas.

A Health Savings Account (HSA) is a tax-advantaged savings account for individuals enrolled in a High-Deductible Health Plan (HDHP). HSAs offer a unique 'triple tax advantage': (1) Contributions are tax-deductible, reducing your taxable income dollar-for-dollar; (2) Investment growth is 100% tax-free—no capital gains or dividend taxes; (3) Withdrawals for qualified medical expenses are completely tax-free. Unlike FSAs, HSA funds roll over indefinitely and remain yours even if you change jobs. After age 65, you can withdraw for any purpose (taxed like a traditional IRA) or continue using tax-free for medical costs. HSAs are often called the 'stealth IRA' because of their powerful retirement benefits.
For 2026, the IRS HSA contribution limits are $4,300 for individual/self-only HDHP coverage and $8,550 for family HDHP coverage. If you're age 55 or older, you can contribute an additional $1,000 catch-up contribution, bringing limits to $5,300 (individual) or $9,550 (family). These limits include both employee and employer contributions. To be eligible, your HDHP must have a minimum deductible of $1,650 (individual) or $3,300 (family) and maximum out-of-pocket of $8,300 (individual) or $16,600 (family) in 2026. Contributions can be made until the tax filing deadline (April 15, 2027 for 2026 contributions).
Yes, but with penalties before age 65. If you withdraw HSA funds for non-qualified expenses before age 65, you'll pay income tax PLUS a 20% penalty on the withdrawal amount. For example, a $1,000 non-medical withdrawal in the 22% tax bracket costs $420 in taxes and penalties. After age 65, the 20% penalty disappears—non-medical withdrawals are simply taxed as ordinary income (like a traditional IRA or 401k withdrawal). Qualified medical expenses include doctor visits, prescriptions, dental, vision, mental health care, and many over-the-counter items (since 2020 CARES Act). Keep receipts—you can reimburse yourself for past medical expenses at any time, even years later, as long as the expense occurred after your HSA was established.
