HDHP vs PPO: How to Choose Your Health Plan at Work, With a Total-Cost Example

Last updated: October 5, 2026. This article is for general information only and is not personal financial, tax, or insurance advice. Plan details vary by employer and insurer, so confirm everything in your own plan documents or with your benefits administrator.

If your employer offers both a high-deductible health plan (HDHP) with a health savings account (HSA) and a traditional PPO, the cheaper monthly premium is rarely the whole story. The better choice depends on what the plan costs you across the full year: premiums, what you pay before insurance helps, what you pay after, and any money your employer adds to an HSA.

This guide gives you a simple way to compare two plans using the same few numbers, plus an illustrative example showing how the answer changes depending on how much care you use.

HDHP vs PPO: The Basic Differences

For 2027, the IRS set the minimum deductible for an HSA-eligible plan at $1,750 for self-only coverage and $3,500 for family coverage, and capped the plan’s out-of-pocket maximum at $8,700 for self-only and $17,400 for family. You can contribute up to $4,500 (self-only) or $9,000 (family) to an HSA, plus a $1,000 catch-up from age 55. Our guide to 2027 HSA contribution limits covers the eligibility rules in detail.

The Five Numbers to Compare

Pull these from each plan’s summary of benefits and coverage before you decide:

1. Your annual premium. Multiply the per-paycheck cost by the number of paychecks in a year.
2. The deductible. The amount you pay for covered care before the plan starts sharing costs. Check whether it is embedded, meaning each person on a family plan has an individual deductible, or aggregate, meaning the family must meet one combined number.
3. Coinsurance or copays. What you pay after the deductible, such as 20% of the bill.
4. The out-of-pocket maximum. The most you can pay in a year for covered in-network care, excluding premiums.
5. Employer contribution. Any money your employer deposits into an HSA, which offsets the higher deductible.

A Worked Example: Total Yearly Cost

The numbers below are made up to show the method. They are not typical for any specific employer. Assume self-only coverage, in-network care, and that both plans use the same 20% coinsurance after the deductible.

Now compare total yearly cost (premium plus what you pay for care) at three levels of medical spending. “Allowed charges” means the insurer’s negotiated price for the care you receive.

How the math works for the moderate case: under Plan A you pay the $1,000 deductible plus 20% of the remaining $3,000, which is $600, for $1,600 in care costs. Under Plan B you pay the $2,500 deductible plus 20% of the remaining $1,500, which is $300, for $2,800.

What this example shows: the HDHP wins when you use little care, because the premium savings are large. At moderate spending, the two plans are close, and the employer HSA contribution tips it toward the HDHP. At very high spending, both plans hit their out-of-pocket maximum, so the difference comes down to the premium gap and the maximums. Your own numbers will differ, and the result changes if the employer contributes nothing, if copays apply, or if you use out-of-network care.

What the Example Leaves Out

• The HSA tax benefit. HSA contributions are generally tax-advantaged, and according to the IRS, earnings grow tax-free and qualified withdrawals are tax-free. The value depends on your tax bracket and state, so it is not counted in the table above.
• Cash flow. A $2,500 deductible can be hard to cover early in the year unless you have savings or HSA funds. A lower-deductible plan may fit better if one large bill would strain your budget.
• Prescriptions. Drug costs can be handled differently. Many HDHPs make you pay the full negotiated price until you meet the deductible, while PPOs often use fixed copays. If you take regular medication, price it plan by plan.
• Networks. A plan that does not include your doctors or hospital can cost more than the premium suggests.

Who Tends to Prefer Each Plan

These are general patterns, not recommendations for any individual.

An HDHP with an HSA often fits people who

• Use little care in a typical year and want lower premiums.
• Can cover the deductible from savings if something happens.
• Want to build an HSA balance that rolls over year to year.
• Have an employer that contributes to the HSA.

A PPO often fits people who

• Expect frequent care, such as therapy, specialist visits, or ongoing treatment.
• Take regular prescriptions that benefit from fixed copays.
• Want predictable costs and a lower deductible.
• Are planning a surgery or pregnancy and expect to hit the out-of-pocket maximum anyway.

Five Rules That Can Change Your Decision

1. FSA conflict. A general-purpose health FSA generally blocks HSA contributions, and this includes a spouse’s FSA in many cases. A limited-purpose FSA for dental and vision is usually allowed. See our FSA open enrollment guide for how to choose.
2. Medicare. Once you enroll in Medicare, you can no longer contribute to an HSA. If you are close to 65, review the Medicare open enrollment guide and your enrollment timing.
3. Employer contributions count toward your limit. If your employer adds $500, your own limit is reduced by that amount.
4. Preventive care. Many plans cover recommended preventive services before the deductible, but check what your plan counts as preventive.
5. Spouse and family options. Compare your spouse’s plan too. The cheapest household option is sometimes a different combination from the one you would pick for yourself.

Open Enrollment Checklist for Choosing a Plan

1. Find your employer’s open enrollment dates and deadline.
2. Collect each plan’s premium, deductible, coinsurance, out-of-pocket maximum, and any HSA contribution.
3. Add up last year’s medical and prescription spending from your insurance statements.
4. Estimate next year’s expected care, including planned procedures, regular visits, and prescriptions.
5. Run the total-cost math for a low, moderate, and high spending scenario for each plan.
6. Confirm your doctors and pharmacy are in-network.
7. If choosing the HDHP, decide how much to put in the HSA and check you have savings to cover the deductible.

If you do not get coverage through an employer and buy on the Marketplace instead, the process differs. See our ACA open enrollment 2027 guide for dates, premiums, and subsidy rules. If you are also deciding how much to save for retirement alongside your health account, our 401(k) and IRA contribution limits guide shows both side by side.

FAQ

Is an HDHP better than a PPO?
Neither is better for everyone. An HDHP can cost less if you use little care, and it unlocks an HSA. A PPO can cost less if you use a lot of care or want predictable copays. Compare the full-year cost using your own expected usage.

What is the 2027 HSA limit?
The IRS limit is $4,500 for self-only coverage and $9,000 for family coverage, with a $1,000 catch-up contribution for people 55 and older.

What is the minimum deductible for an HSA-eligible plan in 2027?
$1,750 for self-only coverage and $3,500 for family coverage, according to IRS Revenue Procedure 2026-24.

Can I have an HSA with a PPO?
Only if the PPO qualifies as an HSA-eligible high-deductible plan. Most traditional PPOs do not.

Does the HSA money expire at the end of the year?
No. HSA balances roll over, and the account belongs to you if you change jobs. That is different from many FSAs.

The Bottom Line

Do not pick a plan on the premium alone. Add up premium, deductible, coinsurance, out-of-pocket maximum, and any employer HSA money, then test the total under light, moderate, and heavy medical use. If you land close to a tie, let your cash cushion and your expected care decide.
