Pension

A pension (; from Latin pensiō 'payment') is a fund or pay-as-you-go scheme into which amounts are paid regularly during an individual's working career, and from which periodic payments are made to support the person's retirement from work. A pension may be either a "defined benefit plan", where defined periodic payments are made in retirement and the contributions to the pension are adjusted to support these defined retirement payments, or a "defined contribution plan", under which defined amounts are paid in during working life, and the retirement payments are whatever can be afforded from the fund.

Pensions should not be confused with severance pay; the former is usually paid in regular amounts for life after retirement, while the latter is typically paid as a fixed amount after involuntary termination of employment before retirement.

The terms "retirement plan" and "superannuation" tend to refer to a pension granted upon retirement of the individual; the terminology varies between countries. Retirement plans may be set up by employers, insurance companies, the government, or other institutions such as employer associations or trade unions. Called retirement plans in the United States, they are commonly known as pension schemes in the United Kingdom and Ireland and superannuation plans (or super) in Australia and New Zealand.

A pension created by an employer for the benefit of an employee is commonly referred to as an occupational or employer pension. Labor unions, the government, or other organizations may also fund pensions. Occupational pensions are a form of deferred compensation, usually advantageous to employee and employer for tax reasons. Many pensions also contain an additional insurance aspect, since they often will pay benefits to survivors or disabled beneficiaries.
