What annuities covers

A fixed annuity credits interest at a rate the insurer declares, locked for an initial period and then reset at the insurer's discretion above a floor written in the contract. The balance cannot go down from market movement; the trade is that the credited rate is what you get, whatever the markets do. Multi-year rate-lock contracts hold one declared rate for the whole term, which makes them behave like a bank certificate issued by an insurer, with tax deferral and without federal deposit insurance.

A fixed-indexed annuity credits interest by a formula tied to a market index, without putting the money in the index. The insurer sets a cap, a participation rate or a spread that limits how much of the index gain is credited, and a floor, usually zero, that stops losses. The formula is reset each term, so the cap you are shown at purchase is not the cap you will have in year five. Reading the crediting method is the whole job with this product; two contracts on the same index can credit very different amounts in the same year.

An immediate annuity starts paying within a year of purchase: you hand over a sum and payments begin, sized by your age, the payout option and the interest rate environment at the time. A deferred annuity accumulates first, sometimes for many years, and converts to income later or is simply withdrawn. Deferred contracts are the ones usually shown to buyers still working; immediate contracts are the purer income tool and are usually bought at or after retirement.

At annuitization you choose how the income is shaped. Life only pays the most per month and stops at death, whatever has been paid out. Life with period certain keeps paying a beneficiary if you die before the certain period ends. Joint and survivor continues for a spouse, at the same or a reduced amount. Each option is a trade between the size of the payment and what survives you, and the choice is usually irreversible once payments start.

A deferred annuity carries a surrender period, commonly several years, during which withdrawals above a stated free-withdrawal amount incur a charge that declines each year. Withdrawals of growth before the federal early-withdrawal age can also carry a tax penalty on top of income tax. The surrender schedule is where the analysis spends the most time: money you may need inside that window does not belong in the contract.

Riders add features for a fee taken from the balance: a guaranteed minimum income benefit that sets a floor on future income regardless of performance, an enhanced death benefit for heirs, or a waiver that lifts surrender charges after a nursing-home admission or terminal diagnosis. A rider's fee is charged every year whether or not it is ever used, so each one is worth pricing against what it would cost to buy the same thing separately.
