HSA Tax Savings Calculator
A Health Savings Account is the only account with a triple tax advantage: contributions are pre-tax, growth is tax-free, and qualified withdrawals are tax-free. This calculator shows your 2026 limit and the taxes you save by contributing.
How this calculator works
For 2026, the HSA contribution limit is $4,400 for self-only coverage and $8,750 for a family, plus a $1,000 catch-up if you are 55 or older. Every dollar you contribute avoids federal income tax at your marginal rate — and, because HSA contributions are made through payroll, they also avoid Social Security and Medicare taxes (7.65%). The calculator totals both savings. Money in the account grows tax-free, and withdrawals for qualified medical expenses are never taxed.
Frequently asked questions
What is the triple tax advantage?
Contributions reduce your taxable income now, investment growth inside the account is tax-free, and withdrawals for qualified medical expenses are tax-free. No other account — not a 401(k) or an IRA — offers all three.
Who can open an HSA?
You must be enrolled in a high-deductible health plan (HDHP) — for 2026, a plan with a deductible of at least $1,700 for self-only or $3,400 for a family — and cannot be covered by another non-HDHP plan or enrolled in Medicare.
Can I invest my HSA money?
Yes. Most HSA providers let you invest your balance in mutual funds or ETFs once it exceeds a small cash minimum. Many people use HSAs as a retirement account: pay current medical bills out of pocket, keep receipts, and reimburse yourself tax-free years later.
