General Annuity Information

Understanding the Accumulation Phase of Annuities

An annuity is a contractual financial product issued by an insurance company designed to accept and grow funds from an individual and then, upon annuitization, pay out a stream of guaranteed payments at a later point in time.

Accumulation vs. Payout

During the accumulation phase, you make initial and ongoing deposits that grow on a tax-deferred basis. During the payout phase, the accumulated principal and earnings are converted into periodic income checks.

Annuity Due vs. Ordinary

In an Annuity Due, payments occur at the beginning of each period, yielding higher total compound return because each contribution immediately earns interest. In an Ordinary Annuity, payments are deposited at period ends.

Tax-Deferred Compounding

Interest and capital gains inside non-qualified annuities grow tax-free until withdrawal. Taxes are paid only upon distributions, allowing your full balance to compound without annual tax drag.
