How to Use This Calculator

  1. Enter your monthly HSA contribution and current balance.
  2. Set years to retirement and expected annual return.

  5. Use Professional for lifetime tax savings across all three HSA benefits.

Formula

Future HSA Balance = PV × (1+r)^n + PMT × [(1+r)^n − 1] / r

where PV = current balance, PMT = monthly contribution, r = monthly rate, n = months to retirement

Annual Tax Savings = Contribution × (Federal rate + State rate + FICA rate)

Example

Age 40, self-only coverage, $300/month contribution, $5,000 current balance, 7% return, 25 years to retirement: HSA balance ≈ $258,000. At 22% federal + 5% state + 7.65% FICA = 34.65% combined rate, annual tax savings on $3,600 contribution ≈ $1,247/year.

Frequently Asked Questions

  • For 2026, the IRS set HSA limits at $4,400 for self-only HDHP coverage and $8,750 for family coverage (per IRS Rev. Proc. 2025-30). Those age 55+ can add a $1,000 catch-up contribution.
  • Contributions are pre-tax (reducing taxable income and FICA), growth is tax-free, and withdrawals for qualified medical expenses are tax-free. No other account in the US offers all three advantages simultaneously.
  • Yes. After age 65, you can withdraw HSA funds for any purpose. Non-medical withdrawals are taxed as ordinary income (like a Traditional IRA) but incur no additional penalty. Medical withdrawals remain completely tax-free.
  • To contribute to an HSA in 2026, you must be enrolled in an HDHP with a minimum deductible of $1,650 (self) or $3,300 (family), and maximum out-of-pocket of $8,300 (self) or $16,600 (family).
  • If you can afford to pay current medical bills from other funds, invest your HSA and let it grow tax-free. Save receipts — you can reimburse yourself years later with no time limit, creating a tax-free cash reserve.
