Attained age is the age of the insured at valuation date, policy anniversary, or contract anniversary.
Insurance mechanics
Premium and coverage features in life insurance frequently change as attained age increases, because mortality and persistence assumptions are updated.
Claims and policyholder impact
Using attained age avoids fixed assumptions from issue date and reflects current age-based risk when contracts renew or convert.
Underwriting rules
Some products use issue age for pricing and keep it fixed; others use attained age with periodic recalculation. Both approaches must be clearly stated in policy documentation.
