How health plan costs work, with worked examples

Four ideas decide what you pay when you use care.

A year of covered in-network care works in order: you pay the deductible, then coinsurance (a percentage) while copays apply to certain services, until you reach the out-of-pocket maximum, after which the plan pays 100%. Premiums are separate.

Limits that apply to the plan you pick

  • ACA out-of-pocket maximum: $12,000 / $24,000 for 2027 (details).
  • HSA-eligible plans: deductible at least $1,750 / $3,500 and maximum no more than $8,700 / $17,400 (2027 limits hub).

To see how these ideas change which plan costs less over a whole year, use the HSA vs PPO calculator or the situation examples. Definitions are also in the glossary.
