Coverage
Sets the 2026 HSA contribution limit and out-of-pocket maximums used below.
HDHP + HSA plan
Lower premium, higher deductible — and the only plan type that lets you open an HSA. For 2026 an HDHP needs a deductible of at least $1,700 self-only / $3,400 family.
PPO plan
Higher premium, lower deductible and more predictable cost-sharing — but no HSA. Copays can be folded into your expected spend below.
Your year
Your best guess at the year's covered costs — visits, tests, prescriptions, procedures. The break-even result shows how sensitive the answer is to this number.
Free money many employers add to your HSA with an HDHP. It lowers the HDHP's net cost and counts toward your annual contribution limit.
Your HSA contribution & taxes
2026 limit: $4,400 self-only — your contribution plus the employer's must stay within this.
HSA contributions cut income tax (and FICA if made through payroll). Note: a few states — notably California and New Jersey — still tax HSA contributions, so verify your state.
PPO side: FSA
A pre-tax FSA you can pair with the PPO. It cuts income tax on the amount you contribute, but it is mostly use-it-or-lose-it, so don't over-fund it.
HSA as an investment
If you pay current costs out of pocket and leave the HSA invested, it grows tax-free. This projects the balance forward (your annual contribution held flat).

HDHP + HSA vs PPO estimate
Where the HDHP+HSA line crosses the PPO line is your break-even spend.
Net cost = premiums + out-of-pocket spend − employer HSA money − tax savings. Lower is better.
How your HSA (and any FSA) cut your tax bill, plus the employer's free contribution.
If you pay current costs out of pocket and invest the HSA instead, the balance compounds tax-free — and after 65 it works like an IRA.

This free healthcare cost savings calculator answers the question every open enrollment raises: is the HDHP with an HSA actually cheaper than the PPO? It compares the true net annual cost of each — premiums, out-of-pocket spend, the employer's HSA money and your tax savings — and shows the break-even where the answer flips.
Pick Basic for a fast answer or Advanced for the full picture. Enter both plans and your expected spend, click Compare, and every number updates instantly — your figures never leave your browser. Updated with 2026 IRS limits.
How It Works
No account, no email, no limits. Just a clear, dollar-for-dollar comparison of what each plan really costs you.
Add each plan's monthly premium, deductible, coinsurance and out-of-pocket max — straight from your benefits summary — plus any employer HSA contribution.
Set your expected medical spend. In Advanced mode, add your HSA contribution, tax bracket and FICA so the HSA tax break counts too.
Get each plan's net annual cost, your yearly savings, the break-even spend, and a chart of how the two costs cross as spending rises.
The Numbers That Shape the Choice
Premiums, deductibles and tax limits set the whole comparison. A few figures worth knowing before you decide.
Why It Matters
Picking by premium alone — or by deductible alone — can cost you four figures a year. The only way to know is to add it all up.
Premium, deductible, coinsurance and the out-of-pocket max all interact. We total them at your expected spend so you see the real cost, not the headline.
There's a spending level where the two plans tie. Below it the HDHP wins; above it the PPO does. We solve for it so you can judge your own year.
The HSA's triple tax advantage can tip the math toward the HDHP — and, invested, it doubles as a tax-free retirement account. We count both.
A healthy year and a heavy one can favor different plans. The scenario view shows which plan wins in each, so you choose with eyes open.
The Basics
Five moving parts decide what a plan costs you. Understanding how they stack is the whole game.
Your total cost for a year is the premium you pay no matter what plus the share of your medical bills the plan makes you cover. That second part climbs as you spend — but only up to a ceiling.
| Cost piece | What it is | When it bites hardest |
|---|---|---|
| Premium | The fixed amount you pay every month to have the plan | Always — even in a year you never see a doctor |
| Deductible | You pay 100% of covered costs until you reach it | Lower-spend years; HDHPs have the highest deductibles |
| Coinsurance | Your percentage share of the bill after the deductible (e.g. 20%) | The middle band of spending |
| Copay | A flat fee per visit or prescription | Frequent visits and ongoing medications |
| Out-of-pocket max | The hard ceiling on what you'll pay in a year; the plan then covers 100% | High-spend years — it caps the damage |
So an HDHP's low premium is offset by a high deductible, while a PPO's higher premium buys a lower deductible and more predictable copays. Which is cheaper depends entirely on how much care you use — which is exactly what the calculator models.
The Trade-off
Same coverage, opposite shapes. One bets on a healthy year; the other buys predictability.
| HDHP + HSA | PPO | |
|---|---|---|
| Monthly premium | Lower | Higher |
| Deductible | Higher (2026: ≥ $1,700 self / $3,400 family) | Lower |
| Cost predictability | Less, until you hit the out-of-pocket max | More — flat copays from day one |
| HSA eligible | Yes — triple tax-advantaged | No (an FSA is the usual pairing) |
| Unused money | Stays yours, rolls over, can be invested | You simply paid a higher premium |
| Best for | Healthy/low spenders & long-term investors | Steady or high medical needs |
The HDHP wins when you spend little (you bank the premium difference and the HSA tax break); the PPO wins when you spend a lot (its lower deductible caps your costs sooner). The break-even spend is the dividing line — and a generous employer HSA contribution pushes that line in the HDHP's favor.
The HSA Edge
No other account is tax-free on the way in, while it grows, and on the way out. That's what can tip the whole comparison.
Contributions are tax-deductible — or pre-tax through payroll, which also dodges the 7.65% FICA tax.
Invested or not, the balance grows 100% tax-free — no tax on interest, dividends or gains, ever.
Spending on qualified medical care is tax-free at any age. After 65, anything else is taxed like a traditional IRA.
A 401(k) is taxed when you withdraw it; a Roth is taxed going in. Only the HSA escapes tax at all three stages — which is what can quietly turn it into a retirement account.
Requires an HDHP, owned by you, rolls over in full forever, and can be invested. The only one that's truly yours to keep and grow.
Pairs with any plan but is employer-owned, capped at $3,400 for 2026, mostly use-it-or-lose-it, and can't be invested.
Fully employer-funded and employer-owned; it reimburses qualified expenses under rules your employer sets.
2026 IRS Limits
Set by IRS Revenue Procedure 2025-19 (and the 2026 FSA limit). These drive the calculator's defaults and caps.
| 2026 figure | Self-only | Family |
|---|---|---|
| HSA contribution limit | $4,400 | $8,750 |
| HSA catch-up (age 55+) | +$1,000 | +$1,000 |
| HDHP minimum deductible | $1,700 | $3,400 |
| HDHP out-of-pocket max | $8,500 | $17,000 |
| Health FSA limit | $3,400 | $3,400 |
To be HSA-eligible, your plan's deductible must be at or above the minimum and its out-of-pocket max at or below the ceiling. Your contribution plus your employer's must stay within the annual limit. Figures from the IRS via SHRM; FSA limit via IRS guidance.
Decide
A rough guide. Run your real numbers above — but this is usually how it shakes out.
| Your situation | Often the better fit |
|---|---|
| Healthy, rarely use care beyond check-ups | HDHP + HSA |
| Want to invest the HSA and grow it tax-free | HDHP + HSA |
| Your employer adds a generous HSA contribution | HDHP + HSA |
| Chronic condition or frequent specialist visits | PPO |
| Planning a baby, surgery, or major procedure | PPO |
| Costly brand-name prescriptions every month | PPO |
| Your expected spend lands near the break-even | Whichever has the better network and cash flow |
Cash flow matters too: an HDHP can leave you facing a big bill before the deductible is met, so a fully-funded HSA (or savings) to cover that gap is part of choosing it wisely.
The Long Game
If you can pay today's smaller bills out of pocket and leave the HSA invested, the math gets powerful.
Most providers let you invest the HSA balance above a small cash buffer. Pay current costs from cash flow and the account compounds tax-free.
Save receipts and you can reimburse yourself tax-free years later — and retirees face large lifetime medical costs the HSA is built to cover.
From age 65, non-medical withdrawals are just taxed as income — no penalty — so the HSA works like a traditional IRA with a medical superpower.
Turn on HSA growth in Advanced mode to project the tax-free balance at retirement and the share that's pure investment growth.

Methodology
No black box. Here is exactly what happens to your numbers.
The tool compares the net annual cost of each plan. Net cost is what the year actually takes out of your pocket: the premiums you pay plus your share of medical bills, minus the money the HDHP gives back through the employer's HSA contribution and your tax savings.
For each plan: net cost = 12 × monthly premium + out-of-pocket(spend) − employer HSA − tax savings. The lower number wins. The PPO side subtracts any FSA tax savings instead of HSA savings.
Your out-of-pocket cost rises in three stages: you pay 100% up to the deductible, then your coinsurance share of everything above it, until you hit the out-of-pocket maximum and the plan covers the rest: OOP = min( deductible + coinsurance × (spend − deductible), out-of-pocket max ).
Your HSA contribution is multiplied by your tax shield — marginal income tax + state tax (+ 7.65% FICA if via payroll) — capped so your contribution plus the employer's stays within the 2026 limit ($4,400 self-only / $8,750 family, +$1,000 at 55+). The PPO can take a parallel FSA tax deduction (2026 limit $3,400).
It scans the full range of medical spend to find where the two net-cost curves cross — the break-even — and reports which plan wins in a low, expected and high spend year so you can see how robust the recommendation is.
If you choose to invest the HSA, it compounds your annual contribution at your chosen return for the years you set — all tax-free — and shows the projected balance, total contributed, and pure growth, with an optional today's-dollars adjustment.
