What Social Security Actually Pays (The Real Numbers)
Before planning around Social Security, you need to know what it actually pays — not what you hope it pays.

If you earned $80,000/year before retiring, you likely need $56,000–$68,000/year in retirement income. Social Security may cover $24,852 of that ($2,071/month × 12). The remaining $31,000–$43,000 per year has to come from somewhere else.
Our retirement income calculator estimates your Social Security benefit based on your current income and planned retirement age — so you can see your income gap without leaving this page. For your official earnings history and benefit projection, you can also visit ssa.gov/myaccount.
Why Social Security Was Never Designed to Replace Your Income
Social Security was created in 1935 as a supplement to retirement savings — not a replacement for your working income. The architects of the program explicitly designed it to cover basic needs alongside personal savings and pensions. But two things have changed dramatically since then:
- Pensions have largely disappeared. According to the Bureau of Labor Statistics, defined benefit pension coverage for private-sector workers has declined from approximately 38% in 1980 to around 15% today. (BLS, 2023) For most Americans, Social Security and personal savings are now the only two sources of guaranteed retirement income — and one is never enough on its own.
- We're living much longer. According to SSA actuarial tables, the average 65-year-old woman can expect to live to approximately age 86, and a significant share of retirees today will live into their 90s. A retirement that may last 25–30 years requires a fundamentally different income strategy than one that lasts 10–15. Use our longevity calculator to estimate how long your income plan may need to last.
The combination — no pension, longer life, and a Social Security benefit that covers less than half your pre-retirement income — creates a structural retirement income gap that most retirees face. The question is not whether the gap exists, but how large it is and how you plan to cover it.
How to Calculate Your Retirement Income Gap
This is a three-part calculation, and it takes less than five minutes if you have your Social Security estimate handy.
Estimate your monthly income need
Use the What Is Your Number? calculator for a personalized estimate based on your housing, healthcare, lifestyle, and spending habits. Or use the rule of thumb: multiply your current gross monthly income by 75–85%.
Look up your estimated Social Security benefit
Log in at ssa.gov/myaccount to see your personalized estimate at different claiming ages. Note that claiming at 62 permanently reduces your benefit by up to 30%; Delaying past full retirement age increases your benefit by 8% per year up to age 70.
Subtract to find your gap
Monthly income need minus Social Security (and any pension income) equals your retirement income gap. This is the number a guaranteed annuity income strategy is designed to fill.
Example Gap Calculation
Monthly income need (based on $75,000/yr earnings)
$4,500
Estimated Social Security benefit (age 67)
− $1,900
Pension income
− $0
Monthly retirement income gap
= $2,600/mo
The Floor Income Strategy: A 4-Step Framework
A floor income strategy means covering your essential monthly expenses — housing, food, healthcare, utilities — with guaranteed, non-market income sources. If your essential expenses are covered by income that cannot run out, you have financial security regardless of what markets do.
Here is the four-step framework for building your floor:
Calculate your total monthly income need
Separate your spending into essentials (must-pay every month) and discretionary (travel, dining, hobbies). Your floor only needs to cover essentials.
Subtract guaranteed income sources
Social Security and any pension income count toward your floor. Subtract both from your essential monthly need.
Identify your gap
The remaining amount is what your floor is missing. This is the amount that must come from non-market, guaranteed sources — not from portfolio withdrawals that depend on market performance.
Use a guaranteed income annuity to fill the gap
Select the annuity type that matches your timeline and gap size. Once the floor is covered, remaining savings can stay invested in growth assets for discretionary spending and inflation protection.
Multiple independent research organizations support the finding that retirees with guaranteed income sources report greater financial security and spend more confidently. A TIAA Institute study on retirement happiness found that guaranteed income is strongly associated with retiree wellbeing. A RAND Corporation working paper on retirement security and financial decision-making found that guaranteed income sources are linked to greater ability to meet essential expenses over time. And a National Bureau of Economic Research working paper by Jeffrey Brown found that life annuities provide meaningful welfare gains by insuring against the risk of outliving assets. The floor strategy is not a product — it's a structure backed by decades of research.
Which Annuity Type Fills Which Gap?
Not all annuities are designed for the same purpose. The right match depends on when you need the income and how large your gap is.
Gap Type: Need income now (retiring within 12 months) | Best Annuity Match: SPIA | Why It Works: Payments begin within 30 days of purchase; guaranteed for life regardless of how long you live
Gap Type: Need income in 5–15 years | Best Annuity Match: DIA | Why It Works: Lock in today's payout rates now; income starts at the date you choose — often significantly higher payouts than a SPIA purchased later
Gap Type: Want growth potential + future guaranteed income | Best Annuity Match: FIA with income rider | Why It Works: Tax-deferred accumulation linked to an index with downside protection; income rider provides guaranteed withdrawals for life regardless of account value
Gap Type: Need safe accumulation before converting to income | Best Annuity Match: MYGA | Why It Works: Guaranteed interest rate for 2–10 years; at maturity, funds can be converted to a SPIA or DIA at then-current rates
Each product links to a full guide with payout examples, suitability frameworks, and current rates. If you are unsure which fits your situation, a licensed advisor can model specific quotes for your gap size and timeline.

What About Inflation?
This is the most common objection to fixed annuity income — and it deserves an honest answer.
Fixed annuity income payments do not automatically adjust for inflation. If you receive $2,000/month from a SPIA today, you will receive $2,000/month in 20 years. Inflation will reduce the purchasing power of that income over time.
However, the floor income strategy accounts for this in two ways:
- Social Security includes annual COLA adjustments. Your Social Security benefit increases each year with the Consumer Price Index, which partially offsets inflation on the guaranteed floor.
- The floor covers essentials, not everything. Growth assets — the portion of savings not used to purchase annuity income — remain invested and available for discretionary spending as purchasing power shifts over time.
For those who want explicit inflation protection, some FIAs with income riders offer optional cost-of-living adjustment provisions, typically at a higher initial withdrawal rate. A licensed advisor can model the trade-off between higher initial income and inflation-adjusted income for your specific situation.
Is a Floor Income Strategy Right for You?
Appropriate For:
- Your essential expenses exceed your Social Security income
- You have a pension gap from a disappearing defined benefit plan
- You are concerned about outliving your savings
- You want to reduce the stress of managing portfolio withdrawals
- Your spouse's income security is a priority
- You have at least $100,000 in savings available to allocate
Not Suitable For:
- Your Social Security and pension already cover all essential expenses
- You may need more than 10% annual liquidity from these funds — most fixed annuities allow penalty-free withdrawals of up to 10% per year, but larger liquidity needs reduce suitability
- You are in poor health with a short estimated lifespan
- Your primary goal is maximizing an estate for heirs
- You have not yet explored maximizing your Social Security benefit first
