Let's find out how much you're leaving on the table.
avg. unreimbursed receipts found
of HSA holders never invest their balance
tax-free potential over a 30-year horizon
Americans 55+ can contribute $4,850 above the standard limit — a benefit most HR departments never explain at open enrollment.
87% of HSA holders leave their balance in a default money market account earning under 1%. The same account can hold Vanguard index funds growing at 7%+ annually — triple tax-free.
"I had $38,000 in a money market account for six years. That's $14,000 I didn't earn." — David Okonkwo, 62, San Jose
of HSA balances never leave cash
There is no time limit to reimburse yourself from your HSA. If you paid out-of-pocket since opening your account — even 12 years ago — every receipt is a tax-free withdrawal waiting to happen.
The day you enroll in Medicare Part A — even if still working — your HSA contribution window closes permanently. Most people discover this 6 months too late, after the retroactive enrollment backdates.
retroactive Medicare enrollment window that catches people off guard
If you're 65+ and still working, enrolling in Medicare Part A retroactively backdates 6 months — which may create an HSA overcontribution penalty. Timing this correctly is worth thousands.
63% of employers contribute to employee HSAs — yet most employees don't know the match amount, the vesting schedule, or whether they're capturing it fully.
"My company puts in $1,500 a year. I didn't know until year four. That's $4,500 I just didn't pick up." — Theresa Nakamura, 59, Portland
of employers offer HSA contributions employees never maximize
Invested at 7% avg. annual return vs. sitting in cash
tax-free gap left on the table
projected value in 2041
"I found $23,000 in receipts from my husband's cancer treatment in 2019. I had no idea I could still reimburse myself tax-free. That was a Tuesday afternoon that changed our retirement."

"My HSA had $41,000 sitting in a money market account earning 0.01%. Compound showed me how to move it into index funds. I'm now on track to have $180,000 by 70 — all tax-free."

"I almost enrolled in Medicare Part A at 64 without realizing it would have killed my catch-up contributions. That one timing insight saved me $4,850 in tax-free contributions."

"My employer was putting in $1,200 a year and I was leaving it in cash. I feel like I've been handed back money I already earned."

Every month your HSA sits uninvested, you're leaving compounding gains on the table. Every year you don't audit your receipts, that reimbursable pile grows — and so does the regret.
