Age Curve

The age curve is the standard schedule for how much premiums rise with age, within the ACA’s 3-to-1 limit for adults. A group’s place on the curve, set by its age mix, shapes its rates.

How does the ACA’s 3-to-1 age rule affect what older workers pay?

June 29, 2026June 28, 2026 by HealthInsuranceFAQs

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.
