The short answer
An income annuity functions much like a pension: both provide guaranteed income for life in exchange for giving up a lump sum. The difference is that a pension is provided by an employer, while an annuity is something you buy yourself from an insurer, effectively creating your own pension. Fewer employers offer traditional pensions today, so some retirees use an annuity to replicate that steady, guaranteed income. Whether that makes sense depends on your income needs, other resources, and comfort with trading a lump sum for lifetime payments.
So an annuity is essentially a self-purchased pension, offering the same guaranteed lifetime income an employer pension would.
How they compare
A traditional pension is funded and managed by an employer and pays you in retirement, sometimes with survivor and inflation features. An annuity you buy gives you control over the amount, timing, and payout options, but you fund it yourself and depend on the issuing insurer. Both trade a lump sum, or years of contributions, for guaranteed income. If you face a pension decision, our guide to pension lump sum vs. monthly covers that choice, and our annuities overview covers building your own income.
The parallel is strong: both convert money into lifetime income, one through an employer, the other through an insurer you choose.
What to weigh
If you are considering an annuity as a private pension, weigh how much guaranteed income you need beyond Social Security, the tradeoff of giving up access to the lump sum, the insurer's financial strength, and payout options like joint-life for a spouse. Because it is a major, largely irreversible decision, review it with a licensed professional. This is educational information, not a recommendation.
The takeaway: an annuity can serve as a self-built pension, guaranteeing lifetime income — weigh your income gap, liquidity, insurer strength, and payout options with a professional.
