How the formula works
Base Premium = Age Factor × Plan Factor × Member Count | Monthly Premium = Base Premium × Family Discount
- Base Premium = Calculated from age, plan type, and member count
- Age Factor = Premium increases with age (1.0 at age 25, +2% per year)
- Plan Factor = Bronze (0.6), Silver (0.8), Gold (1.0), Platinum (1.2)
- Family Discount = 10% discount for 2+ members, 15% for 4+ members
- Annual Premium = Monthly Premium × 12
- Out-of-Pocket Maximum = Deductible + (Total Annual Costs × Coinsurance)
