Annual cost
What a health plan costs beyond the monthly premium
A useful comparison puts the premium and your expected share of care in the same picture. Neither the cheapest monthly payment nor the lowest deductible automatically produces the lowest annual cost.

The five terms to compare
| Term | Plain-language meaning | What not to overlook |
|---|---|---|
| Premium | Amount paid to keep coverage active, usually monthly | Paid whether or not you use care |
| Deductible | Amount you may need to pay before certain cost sharing begins | Some services can be handled differently |
| Copay | Fixed amount for a covered service | Amount and when it applies vary by service |
| Coinsurance | Percentage of the allowed cost you pay | Often applies after the deductible, but check the plan |
| Out-of-pocket maximum | Annual limit on your share for covered, in-network services | Premiums and out-of-network charges can be separate |
A deliberately simple example
Compare the same year across two plans
These numbers are invented only to demonstrate the comparison method. They are not representative premiums, deductibles or limits.
| Illustrative plan | Annual premium | Deductible | Out-of-pocket maximum | Trade-off |
|---|---|---|---|---|
| Plan A — illustrative | $4,800 | $2,000 | $6,000 | Higher premium, lower deductible |
| Plan B — illustrative | $3,000 | $4,500 | $8,000 | Lower premium, higher potential cost sharing |
If you expect little covered care, Plan B's lower premium may look attractive. If you expect substantial in-network care, Plan A's lower deductible and maximum may matter more. You still need the copays, coinsurance, network and service rules to calculate anything meaningful.
Your worksheet
Estimate your own year in six steps
- Write down the annual premium for each finalist.
- List regular prescriptions, recurring visits and any known procedures.
- Confirm which providers and pharmacies are in-network.
- Apply the plan's deductible, copay and coinsurance rules to that expected care.
- Check the out-of-pocket maximum and what does or does not count toward it.
- Compare the estimate with a higher-use scenario so the result is not based on one perfect year.
Common questions
Does meeting the deductible end all cost sharing?+
Not necessarily. Copays or coinsurance can still apply until the plan's out-of-pocket maximum is reached. Read the sequence for each service.
Do premiums count toward the out-of-pocket maximum?+
Premiums are separate from the plan's in-network out-of-pocket maximum. Out-of-network and non-covered charges can also be treated separately.
Is a low-deductible plan always better?+
No. It may have a higher premium or different network and service rules. Compare the total expected year, not one feature.
Can I calculate an exact annual cost in advance?+
Usually not. You can build scenarios using expected care, but actual services, network status and plan rules determine the final amounts.
