DEFINITION of 'Defined-Benefit Plan'. An employer-sponsored retirement plan where employee benefits are sorted out based on a formula using factors such as salary history and duration of employment.
Defined benefit (DB) and defined contribution (DC) plans are different. Since employer-sponsored insurance (ESI) became common in the 1940s, DB plans have dominated the market. With a DB plan, the employer offers employees an insurance policy (or several policies) with a specific range of healthcare benefits.
