The cheapest premium is rarely the lowest cost. Every plan discloses five numbers that determine what you’ll actually pay — and knowing which one matters most for your situation is the difference between a plan that fits and one that bleeds.

More Than Just the Premium: Maria’s Decision
Most of us pick a health plan the way Maria was about to: lowest price, best reviews, name recognition. But a health plan isn’t a streaming service. It’s a contract that determines how much you’ll actually spend on healthcare this year.
Two plans with the same name in different states are completely different. The one that costs $180 per month in premiums might cost Maria—or you—thousands more once you factor in the deductible, doctor visits, and medications. This week, we’re learning how to compare plans the way Maria should have before her decision: by the total cost you’ll pay, not just the monthly premium.
The Five Cost Numbers
When you compare two plans, you’re looking at five numbers that add up to your total cost of ownership. Here’s what each one means:
Number 1
Premium
What you pay every month, whether you use care or not
Number 2
Deductible
How much you pay before insurance kicks in (e.g., $1,200/year)
Number 3
Copay
Fixed amount per visit or prescription (e.g., $25 per doctor visit)
Number 4
Coinsurance
Percentage of the bill you pay after deductible (e.g., 20%)
Number 5
Out-of-Pocket Max
Most you’ll pay per year for covered care (2026: $9,450 individual)
Here’s the key: if you only look at the premium and pick the cheapest one, you might end up with the highest deductible and the highest copays. You could pay less per month but much more per year. So your first job is to write down all five numbers for every plan you’re considering, then do the math.
Plan Types — Network Flexibility
Different plan types determine your cost-sharing when you go out of network:
Plan Type
In-Network
Out-of-Network
Cost-Sharing
HMO
Must use
You pay 100%
Lower premiums
PPO
Preferred
Higher copays/coinsurance
Higher premiums
EPO
Must use (except emergencies)
You pay 100%
Mid-range
POS
Must use specialists
Higher cost, no referral

The In-Network Trick: Two Tiers
Here’s something that surprises most people: “in-network” now has two tiers. Your doctor might be:
Preferred in-network — lower cost-sharing
Non-preferred in-network — higher cost-sharing
Both count as “in-network,” but your bill is different. You have to check which tier your doctor is on in each plan before you choose. This is the gap that’s costing patients thousands in surprise bills.
Medications: The Formulary Check
Health plans publish a list called a formulary—it shows every drug they cover and at what copay tier. Here’s how it works:
Tier 1 (Generics): $10 copay
Tier 2 (Branded Generics): $35 copay
Tier 3 (Brand-Name Drugs): $100 copay
If your medication is on Tier 3, that $50/month difference from Tier 1 adds up to $600 a year. Different plans cover the same medication at different tiers, so you need to check your specific medications before choosing.
What the Data Shows
The Gap Between What People Check and What They Should
Kaiser Family Foundation 2024 Survey (8,217 insured workers): 68% of people look at the premium when comparing plans. 54% check the deductible. 41% look at the out-of-pocket maximum. But fewer than 1 in 3—less than 33%—verify that their current doctor is in-network before they enroll.
That gap explains why so many people get surprise bills from “in-network” doctors they thought were covered.
Commonwealth Fund (2023 peer-reviewed analysis): Many plans now use “tiered” networks where some in-network doctors have lower copays and others have higher ones. Patients often don’t discover which tier their doctor is on until they get a bill.
HealthCare.gov — Cost-Sharing Reductions (CSRs): If you qualify for income-based subsidies, here’s the magic: CSRs are only available on Silver-tier plans. If you get a CSR, your deductible and copays on a Silver plan drop dramatically. They often become lower than a Gold plan that costs you more in premiums. Metal tiers (Bronze, Silver, Gold, Platinum) describe cost-sharing percentages, not quality of care.
Maria’s Action This Week: The Doctor Check
Do this for every plan you’re considering. Maria’s one thing today: verify your doctor.
1
Write down the five numbers: Monthly premium, annual deductible, your typical copay, coinsurance percentage, out-of-pocket maximum. Do this for each plan.
2
Maria’s must-do: Verify your doctor (3 minutes). Go to the plan’s provider directory online or call their member services number. Search your current primary care doctor by name. Check whether they’re listed as “preferred in-network” or “non-preferred in-network.” If your doctor isn’t listed, call the plan and ask. Then search for any specialists you see regularly. Write down their status for each plan. This is the step that catches surprises.
3
Check your medications: Use the plan’s formulary checker tool or call and ask: “What tier is [medication name] on, and what’s my copay?” Write it down for each medication you take, for each plan. Multiply the copay by 12 months to see your annual medication costs.
4
Do the math: Create a simple spreadsheet with these columns: Plan Name | Monthly Premium | Annual Deductible | Copay per Visit | Estimated Annual Doctor Visits | Estimated Annual Medication Costs | Estimated Total Annual Cost. The plan with the lowest “estimated total annual cost” is your choice.

James is comparing two plans. Plan A has a $120 monthly premium but a $7,500 deductible. Plan B has a $340 monthly premium but a $1,500 deductible. He takes three prescriptions that cost $400/month combined. Which plan is likely cheaper for him over the year?
The cheapest premium is rarely the lowest cost. James takes $4,800/year in meds. On Plan A he’d pay the first $7,500 of medical costs out-of-pocket PLUS the $1,440 premium = $8,940+. On Plan B, the premium is $4,080/year, and the $1,500 deductible is met quickly — total exposure is closer to $5,600. The Five Vital Numbers (premium, deductible, OOP max, copay structure, formulary tier) beat premium-shopping every time.
Do This Now
Pick one plan you’re considering, then verify ONE thing today: open the insurer’s provider directory and search your primary care doctor’s name. Screenshot the in-network confirmation. Repeat for each plan this week. A single out-of-network doctor can double your annual cost.
