A defined Benefit pension defines the benefit to the worker based on salary basis, years worked, and a multiplier. An example might be 2@55 final 3, meaning that the annuity is the highest 3-year average salary times years worked times 2% (if age 55). A worker with 30 years service would receive 2*30 or 60% of their salary. Some systems allow a worker to receive more than 100% salary by various maneuvers to alter the final salary basis.
