The ANB Rounding System Mechanics

Under the Age Nearest Birthday (ANB) standard, if an individual is 35 years, 6 months, and 1 day old, their risk profile is calculated as a 36-year-old. If they are exactly 35 years and 5 months old, they register under the lower 35-year risk premium. Identifying this transition window allows policy buyers to lock in preferred premium tiers before passing the 6-month rounding threshold.
