A Health Savings Account is available to anyone enrolled in a qualifying high-deductible health plan (HDHP). Unlike a Flexible Spending Account, HSA balances roll over indefinitely — there's no year-end deadline to spend them — and the account belongs to you, not your employer. Contributions are tax-deductible (or pre-tax via payroll), growth is tax-free, and withdrawals for qualified medical expenses are tax-free too, which is why it's often called "triple tax-advantaged."
It projects your current balance plus future annual contributions forward using compound growth, based on your expected annual return. It also checks your entered contribution against the 2026 IRS limit for your coverage type (plus the $1,000 catch-up if you're 55 or older) and flags it if you've entered more than the allowed limit.
Projected Balance = Current Balance × (1+r)^n + Annual Contribution × (((1+r)^n − 1) ÷ r), where r = annual return, n = yearsFor 2026, the IRS limit is $4,400 for self-only HDHP coverage and $8,750 for family coverage. Those age 55 or older can contribute an additional $1,000 catch-up, for totals of $5,400 (self-only) and $9,750 (family).
Unlike a Flexible Spending Account, HSA balances roll over year to year with no use-it-or-lose-it deadline, the account is yours even if you change jobs, and after age 65 you can withdraw funds for any purpose (paying regular income tax, but no penalty) — making it usable as a supplemental retirement account.
Contributions are tax-deductible (or pre-tax through payroll), the balance grows tax-free, and withdrawals for qualified medical expenses are also tax-free — no other common account offers all three advantages at once.
