Age rating lets insurers charge older adults more than younger ones, capped by the ACA at a 3-to-1 ratio. Premiums rise along a standard age curve, so a group’s age mix has a direct effect on its rates.
The ACA caps the oldest adult’s premium at three times the youngest adult’s for the same plan, so coverage is relatively cheaper for older workers and pricier for younger ones than raw cost would suggest.
Under age rating, premiums rise with age up to a 3:1 cap, so older employees have higher individual premiums. A percentage-of-premium employer contribution helps offset that by paying more, in dollars, for them.
Employers set one contribution strategy, a percentage of premium or a flat dollar amount; applied consistently. Because age-rated premiums already rise with age, a percentage contribution naturally pays more for older employees.
Age (member-level) rating charges a separate premium for each person based on age; composite rating charges the same tier rates for everyone regardless of age, using a blended average.
No. New York is a pure community-rating state, so small-group premiums don’t vary by age, gender, or health; only by plan, geography, and family tier.
