An annuity is a contract between you (the purchaser or owner) and an insurance company. In its simplest form, you pay money to an annuity issuer, and the issuer then pays the principal and earnings back to you or to a named beneficiary. Annuities are generally used to provide income in retirement.
Most life insurance companies sell annuities. You pay the insurance company a sum of money, either all at once or incrementally. The type of annuity you own determines whether your money earns a fixed amount or an amount that depends on the equities in which the annuity is invested.
