Should You Pay for Prescription Glasses with Your HSA - or Invest and Reimburse Later?
Prescription eyeglasses correct vision problems like nearsightedness, farsightedness, and astigmatism. Costs vary widely depending on frames and lens options.
Prescription Glasses typically costs $400
Range: $200 – $800. Here's how each strategy plays out.
Side-by-Side Comparison
| Pay with HSA Now | Pay Cash, Reimburse Later | |
|---|---|---|
| Out-of-pocket today | $0 | $400 |
| HSA balance impact | -$400 | No change |
| Tax savings | $120 (immediate) | $120 (when you reimburse) |
| HSA value in 10 years | $0 from this expense | +$387 in growth |
| HSA value in 20 years | $0 | +$1,148 in growth |
The Verdict
At $400, Prescription Glasses falls in a gray area. The potential investment growth of $387 over 10 years is meaningful but not life-changing. If you can easily pay out of pocket, the shoebox strategy still wins mathematically. But the convenience of paying directly from your HSA is a reasonable trade-off for smaller expenses.
Consider batching smaller expenses: if you pay for multiple procedures out of pocket over a year, the combined growth adds up.
Key Assumptions
7% annual return
Based on historical stock market average returns
30% combined tax rate
Federal + state income tax + FICA
Compounding annually
Actual returns will vary year to year
When to Pay with Your HSA Instead
The shoebox strategy is not for everyone. Paying directly with your HSA makes more sense when:
- You do not have cash on hand. If paying $400 out of pocket would strain your budget or emergency fund, use your HSA. That is what it is for.
- The amount is small. For expenses under $200-300, the potential investment growth may not be worth the effort of saving receipts and tracking reimbursements.
- You need the money now. If you are facing a financial emergency or carrying high-interest debt, preserving cash by using your HSA is the smarter move.
- You are not investing your HSA. The shoebox strategy only works if your HSA is invested. Money sitting in a savings account earning 0.1% does not benefit from deferral.
