HSA Retirement Calculator

Use this calculator to project an HSA balance when used as a long-term retirement savings vehicle.

What this calculator does

The HSA retirement calculator estimates how contributions, medical withdrawals, and investment growth may affect an HSA balance by retirement. It treats the HSA as a long-term tax-advantaged account.

It uses:

• current age and retirement age
• current HSA balance
• annual HSA contribution
• annual medical withdrawals and expected return

HSA Retirement Formula

FV = P(1 + r)^n + Net Contribution × (((1 + r)^n - 1) / r)

Where:

• P = current HSA balance
• Net Contribution = contribution minus medical withdrawals
• r = expected annual return
• n = years until retirement

Example calculation

If:

• Current HSA balance = 10,000
• Annual contribution = 4,300
• Medical withdrawals = 0
• Expected return = 6%

Then:

• Net annual addition = 4,300
• Contributions grow over time
• Existing balance compounds
• Retirement medical capacity increases

The HSA can become a meaningful retirement health fund.

What is HSA retirement planning?

HSA retirement planning uses a Health Savings Account as a long-term savings vehicle. Qualified medical withdrawals can be tax-free when rules are met.
