HSA vs FSA Decision Helper
Compare tax savings, employer money, deductible risk, forfeiture risk, and provider needs.
Read: HSA vs FSA GuideHSA contributions generally require HSA-eligible HDHP coverage.
Expenses you can reasonably predict this year.
Annual amount you would add to the HSA.
Annual amount you would elect for the FSA.
Annual employer contribution.
Annual premium savings versus another plan.
Added deductible exposure versus the safer plan.

Use $0 if no carryover or grace-period protection is available.
- HSA value = employer HSA money + HDHP premium savings + estimated tax savings.
- Risk-adjusted HSA value subtracts deductible exposure not covered by your cash cushion.
- FSA net value = estimated tax savings - possible forfeited dollars.
- FSA forfeiture risk falls when predictable expenses and carryover/grace-period protection are high.
The HSA path looks stronger on these assumptions, mainly because of employer money, premium savings, tax savings, and enough cash cushion.
The account type is only one part of the decision.
For HSAs, compare fees, cash yield, investment access, debit-card access, transfer rules, and employer payroll integration. For FSAs, compare carryover, grace period, runout deadline, receipt rules, claims workflow, debit-card limits, and whether predictable expenses justify the election.
