An income floor is reliable lifetime income that covers your essential expenses no matter what the markets do. For most retirees, Social Security is the foundation of that floor. Some people add a pension or an income annuity to cover the rest, and keep their remaining savings invested for flexibility and growth.
What is a retirement income floor?
Think of your retirement budget as a house. The floor is the part that has to hold up every day: housing, food, utilities, insurance and healthcare. The rooms above it are the extras, like travel, hobbies and gifts. An income-floor approach pays for the floor with income sources designed to last for life, and pays for the extras from savings you can adjust. If markets fall, you may trim a trip, but the essentials stay covered. This is the same idea behind How to Create Your Own Pension in Retirement: rebuild the steady paycheck that a traditional pension used to provide.
Start with Social Security, your built-in floor
Social Security pays for life, and benefits generally receive an annual cost-of-living adjustment. Your claiming age makes a big difference. For anyone born in 1960 or later, full retirement age is 67. Claiming at 62 permanently reduces your benefit by 30%. Waiting past 67 earns delayed retirement credits of 8% per year until age 70 (source: ssa.gov).
Hypothetical example: someone whose full-retirement-age benefit is $2,000 a month would get about $1,400 at 62, or about $2,480 at 70. For couples, the higher earner's claiming age can also affect the surviving spouse's benefit. Delaying isn't right for everyone. Health, other savings and the need for income now all matter. You can get your own estimate at ssa.gov/myaccount.
Measure the gap between your floor and your essentials
Add up your essential monthly expenses and subtract Social Security and any pension. What's left is your essential income gap. Hypothetical example: $4,200 of essential expenses minus $2,800 of Social Security leaves a $1,400 monthly gap. Our step-by-step guide, What Is a Retirement Income Gap and How Do You Calculate It?, walks through this, and the calculator on our home page gives you a quick estimate.
Where an income annuity can fit
An income annuity is a contract with an insurance company: you pay a premium, and the insurer pays you income, which can be guaranteed for life. Some people use one to fill part or all of the essential gap, creating a "personal pension" that sits on top of Social Security. Payments are guaranteed only by the financial strength and claims-paying ability of the issuing insurer, which is why insurer ratings matter. Payout amounts depend on your age, the payout option you choose (such as life-only, joint life or period certain) and rates when you buy, so compare current quotes rather than relying on rules of thumb.
The trade-offs to weigh
An income floor isn't free, and an annuity isn't right for everyone. Weigh these trade-offs:
- Liquidity: money used to buy lifetime income is usually no longer available as a lump sum. Keep an emergency reserve.
- Inflation: many annuity payments are level. Unlike Social Security, they may lose purchasing power over time unless you choose an increasing-payment option, which typically starts lower.
- Fees and surrender charges: some annuity types carry fees or surrender periods. Read the contract and ask what you're paying for.
- Legacy: life-only payments stop at death. Refund or period-certain options protect heirs but pay less each month.
- Timing: delaying Social Security, buying an annuity or doing both are related decisions. Look at them together.
Putting it together
A simple order of operations:
- List your essentials.
- Decide on a Social Security claiming strategy.
- Measure the remaining gap.
- Decide how much of that gap, if any, you want covered by guaranteed lifetime income versus withdrawals from savings.

Questions people ask
Does Social Security count as part of an income floor?
Yes. For most retirees, it is the largest source of lifetime, inflation-adjusted income and the natural starting point.
Should I delay Social Security if I buy an annuity?
Some people use savings or an annuity to bridge the years before claiming a larger benefit. Whether that makes sense depends on your health, other assets and household. It is a decision to model carefully.
How much of my savings should go into an annuity?
There is no universal percentage. Many planners start by covering only the essential gap, not all spending, so you keep flexibility.
Are annuity payments guaranteed?
Guarantees are backed by the financial strength and claims-paying ability of the issuing insurance company, not by the government.
Is an income floor the same as the 4% rule?
No. The 4% rule is a withdrawal guideline for investments. An income floor uses lifetime income sources for essentials and leaves withdrawals for the extras.
