Maximize the triple tax advantage of your Health Savings Account.
HSA Contribution Optimizer — Triple Tax Advantage
Health Savings Accounts (HSAs) are the only U.S. account with a triple tax advantage: contributions reduce taxes today, growth is tax-free, AND withdrawals for medical expenses are tax-free. This calculator shows your immediate tax savings + decades of compound growth if you invest the balance.

Pro tips
- Pay current medical bills out-of-pocket — let your HSA grow tax-free for decades. Reimburse yourself later.
- Keep receipts forever — you can reimburse any qualified expense any time later (no statute of limitations).
- After 65, you can withdraw for non-medical reasons (taxed like a 401k) — making it a 'super-Roth'.
Frequently asked questions
Can I have an HSA without a HDHP?
No — HSAs require enrollment in an HSA-qualified High Deductible Health Plan.
Can I invest my HSA?
Yes — most providers (Fidelity, Lively, HSA Bank) let you invest in index funds once you hit a small cash threshold.
Does my employer's HSA contribution count?
Yes — employer contributions count toward your annual limit. Both you and your employer can contribute.
