Defined contribution

A defined contribution (DC) plan is a type of retirement plan in which the employer, employee or both make contributions on a regular basis. Individual accounts are set up for participants and benefits are based on the amounts credited to these accounts (through employee contributions and, if applicable, employer contributions) plus any investment earnings on the money in the account. In defined contribution plans, future benefits fluctuate on the basis of investment earnings. The most common type of defined contribution plan is a savings and thrift plan. Under this type of plan, the employee contributes a predetermined portion of his or her earnings (usually pretax) to an individual account, all or part of which is matched by the employer.

Defined contribution plans have become widespread all over the world in recent years and are now the dominant form of plan in the private sector in many countries.

For example, the number of defined contribution plans in the US has been steadily increasing, as more and more employers see pension contributions as a large expense avoidable by disbanding the defined benefit plan and instead offering a defined contribution plan.

Money contributed can either be from employee salary deferral or from employer contributions. The portability of defined contribution plans is legally no different from the portability of defined benefit plans. However, because of the cost of administration and ease of determining the plan sponsor's liability for defined contribution plans (no actuary is needed to calculate the lump sum equivalent unlike for defined benefit plans), in practice, defined contribution plans have become generally portable.
