What if you invest your HSA?

Many people spend HSA money as they go. Others pay medical bills from other money and leave the HSA invested. Use this to see how the split could change the balance over time.

Assumptions

  • You contribute the same amount every year and spend the chosen share that year. Spent money earns nothing.
  • Invested money grows at one steady yearly rate, added at year end. Fees, cash minimums and taxes are ignored.
  • Future limits are usually adjusted for inflation; this uses the 2026 figure only to flag amounts over today’s limit.

Fees matter here too. Compare providers in the HSA directory, or see whether moving your HSA pays off.
