The mechanics in plain language
With a single-premium immediate annuity (SPIA), you pay a lump sum and receive payments that can continue for life. The insurer prices your age and the interest-rate environment into the payout.
Deferred designs let assets grow first, then convert to income later, or attach a guaranteed lifetime withdrawal benefit (GLWB) rider to a deferred annuity. Riders add guarantees and usually add fees. Read the fee drag and the conditions for keeping the guarantee.
