Key Takeaways
- HDHPs have lower premiums but out-of-pocket maximums can hit $7,500 for individuals in 2025. A single bad year wipes out years of premium savings.
- Picking a PPO without running the math costs healthy people an average of $900 to $1,500 in unnecessary premiums every year.
- Calculate your break-even point by comparing total annual premiums plus expected out-of-pocket costs across both plans, then factor in HSA tax savings.

The Question Nobody Asks at Open Enrollment
Every fall, millions of Americans stare at a benefits portal. Two plans sit side by side. The HDHP shows a low monthly premium. The PPO shows a high one. Most people click PPO, tell themselves it feels safer, and move on.
That instinct costs real money.
The premium is just one piece. The full picture includes deductibles, copays, coinsurance, out-of-pocket maximums, and the HSA tax break you get with an HDHP. Once you add all of that together, the answer sometimes flips completely.
Here is how to actually run the numbers.
What You Are Really Comparing
Think of both plans as buckets. You pour money in throughout the year. The bucket that costs less total wins.
The HDHP bucket fills with:
- Lower monthly premiums
- A high deductible you pay before coverage kicks in (minimum $1,650 for individuals in 2025)
- Coinsurance after the deductible
- An out-of-pocket maximum (up to $8,300 for individuals in 2025)
- Minus the HSA tax savings you earn
The PPO bucket fills with:
- Higher monthly premiums
- A lower deductible
- Copays at every visit
- Coinsurance after the deductible
- An out-of-pocket maximum
Neither bucket is automatically cheaper. It depends entirely on how much healthcare you use.
The Formula That Actually Matters
Here is the core calculation. Write this down.
Total Annual Cost = Annual Premium + Expected Out-of-Pocket Costs
For the HDHP, subtract your HSA tax savings from that total.
That last part matters more than most people realize. If you contribute $3,850 to an HSA (the 2025 individual limit) and you are in the 22% federal tax bracket, you save $847 in federal taxes alone. Add state tax savings and that number climbs higher. Your employer might also contribute to your HSA, which cuts the HDHP cost further.
Worked Example 1: The Healthy 28-Year-Old
Meet Jordan. Single, 28, works at a mid-size company. Jordan goes to the doctor twice a year for routine checkups. No prescriptions. No chronic conditions.
Jordan's PPO:
- Monthly premium: $280
- Annual premium: $3,360
- Annual deductible: $500
- Two routine visits (covered at 100% after deductible): $0 additional
- Total annual cost: $3,360
Jordan's HDHP:
- Monthly premium: $110
- Annual premium: $1,320
- Annual deductible: $1,500
- Two routine visits (covered at 100% as preventive care): $0 additional
- HSA contribution: $3,850, tax savings at 22% bracket: $847
- Total annual cost after tax savings: $473
The difference? Jordan saves $2,887 per year on the HDHP.
Over five years with no major health events, that is $14,435 in savings. That money compounds inside the HSA if Jordan invests it. A healthy person paying PPO premiums is essentially buying a very expensive insurance policy against a scenario that statistically may never come.
Worked Example 2: The Person With Real Medical Needs
Now meet Sam. 41 years old, one kid on the plan, manages Type 2 diabetes. Sam sees a specialist quarterly, fills two prescriptions monthly, and had one urgent care visit last year.
Sam's PPO (employee plus child):
- Monthly premium: $520
- Annual premium: $6,240
- Annual deductible: $750 per person
- Specialist copays (4 visits at $60 each): $240
- Prescriptions (2 drugs, $40/month each): $960
- Urgent care copay: $75
- Total annual cost: $7,515
Sam's HDHP (employee plus child):
- Monthly premium: $310
- Annual premium: $3,720
- Annual deductible: $3,000 per person
- Specialist visits before deductible met (4 visits at ~$200 negotiated rate): $800
- Prescriptions before deductible met (~$150/month): $1,800
- Urgent care before deductible: $180
- HSA tax savings at 22%: $660 (contributing $3,000)
- Total annual cost: $5,840
Even with Sam's regular medical usage, the HDHP still wins by $1,675 per year. The premium difference carries enough weight to overcome the higher cost-sharing.
But here is the critical point. If Sam had a major surgery or hospitalization on top of routine care, the math shifts fast. Sam hits the HDHP out-of-pocket maximum of $6,850 for a family in a bad year. That same bad year on the PPO might have a $4,000 family out-of-pocket maximum.
This is exactly why you need to run three scenarios, not one.
Run Three Scenarios, Not One
Most people calculate the "normal year" scenario. That is a mistake.
Run all three of these:
- Best case year. You stay healthy. Preventive care only.
- Average year. Your typical usage based on the last 2 to 3 years.
- Worst case year. You hit your out-of-pocket maximum on both plans.
In the worst case scenario, compare the maximum you could possibly pay on each plan plus the full annual premium. That number tells you your financial exposure if everything goes wrong.
For many people, the worst case on an HDHP and the worst case on a PPO are closer than expected. The HDHP often still wins because the premium savings partially offset the higher out-of-pocket maximum.
The HSA Advantage Nobody Talks About Enough
The Health Savings Account attached to an HDHP is not just a medical savings account. It is a triple-tax-advantaged investment account.
Contributions go in pre-tax. The money grows tax-free. Withdrawals for medical expenses come out tax-free. No other account in the US tax code does all three.
After age 65, you can withdraw for any reason, just like a traditional IRA. The HSA essentially becomes a bonus retirement account once your medical costs are covered.
The 2025 HSA contribution limits:
- Individual coverage: $4,300
- Family coverage: $8,550
- Catch-up contribution if you are 55 or older: add $1,000
If you max out an HSA for 20 years and invest it aggressively, you could accumulate over $200,000 in tax-free funds. That is not a rounding error. That is a retirement strategy.
When the PPO Actually Wins
The PPO is not always the wrong answer. Here are situations where it legitimately makes sense.
You have predictable high medical costs. If you know you will hit or exceed your HDHP deductible every single year, the math sometimes favors the PPO because of lower per-visit cost-sharing.
You are pregnant or planning to be. Maternity care costs accumulate fast. Model out the full delivery cost under both plans before deciding.
You have a complex chronic condition. Multiple specialists, frequent labs, and expensive specialty drugs can push HDHP out-of-pocket costs well above the premium savings.
Your employer offers a lousy HDHP. Some employers pick HDHPs with high premiums AND high deductibles. That removes the whole point. Check the actual numbers on your specific plan.
How to Find Your Break-Even Point
The break-even point is the annual out-of-pocket spending level at which both plans cost exactly the same.
Here is the shortcut formula:
HDHP Break-Even = (PPO Annual Premium minus HDHP Annual Premium) + HDHP Deductible
If your expected medical costs land below that number, the HDHP wins. Above it, the PPO starts to pull ahead.
For Jordan from the first example:
- Premium difference: $3,360 minus $1,320 = $2,040
- HDHP deductible: $1,500
- Break-even out-of-pocket spending: roughly $3,540
Jordan would need to spend over $3,540 out of pocket before the PPO becomes the better deal. That is a lot of doctor visits for a healthy 28-year-old.
Stop Guessing. Start Calculating.
Open enrollment windows close fast. Most people spend less than 20 minutes on this decision despite it affecting thousands of dollars.
You now have the framework. Three scenarios, total annual cost on each plan, HSA tax savings factored in, and a break-even point to anchor the decision.
Pull up your plan documents. Find the monthly premium, deductible, coinsurance rate, and out-of-pocket maximum for each option. Then run the math with real numbers from your actual life.
Our HDHP vs PPO calculator does all of this in about two minutes. Plug in your premium costs, your expected medical usage, your tax bracket, and any employer HSA contributions. It spits out your total cost under each plan across all three scenarios.
Stop leaving money on the table because the PPO felt safer. Safer feelings are not the same as better outcomes.
