HSA Triple Tax Advantage Calculator: Keep More of Your Healthcare Dollars
Calculate how much you save with tax-deductible contributions, tax-free growth, and tax-free withdrawals — then compare spending now versus investing for the long run.
An HSA provides triple tax advantages: tax-deductible contributions, tax-free growth, and tax-free withdrawals for qualified medical expenses. Unlike an FSA, unspent HSA funds roll over indefinitely and can be invested like a retirement account. This calculator compares two paths: using your HSA for today's medical bills, or paying out-of-pocket now to let the balance grow tax-free for decades.
