It's permanent life insurance that combines a death benefit with a cash value account that grows based on a market index's performance — without your money being directly invested in the market.
Term life only pays a death benefit for a fixed period and builds no cash value. IUL is permanent coverage that also accumulates cash value you can access while you're alive.
It's a strong fit if you want coverage that isn't tied to an employer, need flexible premiums for irregular income, and want a living benefit you can tap if illness takes you off the road.
