Deductibles & Out-of-Pocket Limits in Stillwater
The premium is what you pay monthly; the deductible is what you pay before the plan starts sharing costs, and the out-of-pocket maximum is the most you can pay in a year. A cheaper premium usually means a higher deductible.
| Metal tier | Plans | Typical deductible | Deductible range | Typical out-of-pocket max |
|---|---|---|---|---|
| Bronze | 13 | $7,500 | $3,500–$10,600 | $10,000 |
| Silver | 12 | $6,000 | $2,000–$8,000 | $8,900 |
| Gold | 12 | $1,500 | $250–$2,000 | $8,200 |
Typical is the middle plan in each tier, not an average, since one $0-deductible variant would otherwise drag the figure below anything on offer. Silver plans can carry much lower deductibles than shown if you qualify for cost-sharing reductions. Check what you qualify for.
