HSA vs traditional total savings: the long-run wealth gap
This HSA vs traditional total savings calculator projects what a Health Savings Account is really worth when you treat it as a long-term investment account rather than a year-to-year spending pot. Instead of comparing this month's premiums, it compounds your contributions, your employer's contributions, and investment growth across many years — so you can see the balance an invested HSA builds and the lifetime tax it saves you compared with parking the same money in an ordinary taxable account.
The case for the HSA is its triple-tax advantage: money goes in pre-tax, grows tax-free, and comes out tax-free for qualified medical costs. A traditional taxable account gets none of those three — which, over decades, is the gap this tool makes visible.
The triple-tax advantage — and what a taxable account loses
An HSA is the only account in the US tax code that is untaxed at all three stages. A regular taxable brokerage account is taxed at two of them, and that drag is what the long-run comparison turns on.
| Stage | Invested HSA | Taxable account |
|---|---|---|
| Money going in | Deducted from income (pre-tax) | After-tax dollars |
| Growth each year | Tax-free | Dividends and realized gains taxed |
| Qualified medical withdrawals | Tax-free | N/A — no medical break |
| Non-medical withdrawal after 65 | Taxed as ordinary income, no penalty | Only the gain is taxed (capital gains) |
Source: IRS Publication 969. Contributions are deductible, earnings are tax-free, and qualified distributions are tax-free; after age 65 non-qualified withdrawals are taxed as income with no additional tax.
IRS Publication 969 confirms the three benefits: a deduction for contributions, tax-free earnings on the account, and tax-free distributions for qualified medical expenses.How the projection is calculated
The calculator grows the balance one year at a time: each year it earns your expected return, then adds your contribution plus any employer contribution. Alongside the ending balance, it tallies what you put in and the income tax your own contributions saved.
A worked example: 20 years of an invested HSA
You start with $5,000, add $4,000 of your own each year, your employer adds $1,000, you earn 7% a year, and you leave it invested for 20 years while in the 22% bracket.
Step 1 — Compound the balance
Growing $5,000 plus $5,000 of total annual contributions at 7% for 20 years produces an ending balance of about $224,326, against $105,000 of total money paid in.
Step 2 — Add up the deduction
Only your own $4,000 a year earns the deduction: $4,000 × 22% × 20 = $17,600 in income tax saved over the period — before counting the tax-free growth.
Step 3 — Compare to a taxable account (illustrative)
Saving the same money in a taxable account would forfeit that $17,600 deduction up front, and yearly tax on dividends and gains would shave roughly a percentage point off the return — illustratively dragging a comparable 7% gross down toward ~6% net, which over 20 years leaves the taxable balance tens of thousands of dollars behind the HSA. (This contrast is a hand-calculation; the calculator itself projects the HSA balance, not the taxable alternative.)
After age 65, an HSA acts like a traditional IRA
The long-run case rests on what happens once you stop needing the account purely for medical bills. Before 65, a non-medical withdrawal is taxed as income plus a 20% penalty. At 65 the penalty disappears.
- Qualified medical spending stays tax-free at any age — the best use of the balance for life.
- Non-medical withdrawals after 65 are simply taxed as ordinary income, with no extra penalty — exactly like a traditional IRA distribution.
- You can reimburse old medical bills paid out of pocket years earlier (as long as they post-date the account), turning saved receipts into tax-free withdrawals later.
2026 HSA contribution limits
How fast the balance can grow is bounded by the annual contribution limit, which the IRS indexes for inflation. The 2026 figures set the ceiling on the money side of the projection.
| 2026 HSA limit (IRS §223) | Self-only | Family |
|---|---|---|
| Annual contribution limit | $4,400 | $8,750 |
| Age 55+ catch-up | +$1,000 | +$1,000 |
| Effective limit at 55+ | $5,400 | $9,750 |
Source: IRS Rev. Proc. 2025-19. The limit covers your and your employer's contributions combined; the catch-up adds $1,000 from age 55.

- Invest the balance, don't let it sit in cash. The tax-free growth is the largest of the three benefits, and it only works if the money is actually invested.
- Pay current medical bills out of pocket if you can, leaving the HSA to compound, and reimburse yourself later with saved receipts.
- Contribute to the annual limit when cash flow allows — the deduction and the compounding both scale with what you put in.
- Add the $1,000 catch-up from 55 to squeeze in more tax-advantaged dollars near retirement.
Key terms
How accurate is this projection?
The compounding math is exact, but the inputs are assumptions: investment returns vary year to year and are not guaranteed, future contribution limits will change with inflation, and your tax bracket may shift in retirement. The tax-savings figure counts only the deduction on your contributions, so it understates the real benefit, which also includes years of tax-free growth and tax-free medical withdrawals. The taxable-account comparison in the example is an illustrative hand-calculation, not an output of the tool.

About this HSA vs traditional total savings calculator
This HSA vs traditional total savings calculator runs entirely in your browser — nothing you enter is sent anywhere. It compounds your contributions, your employer's contributions and investment growth year by year to project an invested HSA's long-run balance and the income tax your contributions save, so you can compare it against saving the same money in an ordinary taxable account. Returns are assumptions, not guarantees, and the tax figure counts only the contribution deduction, so the real triple-tax advantage is larger.
