Introduction

Social Security pays benefits to nearly 71 million Americans in 2026, and the Social Security Administration raised the cost-of-living adjustment by 2.8% for January 2026. Yet most workers cannot explain how their own benefit is computed. The math is not intuitive: Social Security indexes your 35 highest years of earnings to national wage growth, averages them into the Average Indexed Monthly Earnings (AIME), then runs the result through three bend points that pay 90 cents on the dollar for low earnings, 32 cents for middle earnings, and 15 cents for high earnings. The 2026 bend points are $1,286 and $7,749. The result is your Primary Insurance Amount, the benefit you receive at Full Retirement Age. Claim earlier and it is permanently reduced. Claim later and it grows by 8% per year up to age 70. This estimator applies the 2026 formula so you can see the tradeoff.

What This Calculator Does

This tool estimates your monthly Social Security retirement benefit at any claim age from 62 to 70. You enter your birth year (which sets your Full Retirement Age), your average annual earnings across your 35 highest years in 2026 dollars, and the age you plan to claim. The calculator computes your AIME, applies the 2026 PIA bend points ($1,286 and $7,749) to produce your Primary Insurance Amount, then applies the early retirement reduction or delayed retirement credit for your chosen claim age. It also shows the benefit at 62, Full Retirement Age, and 70 side by side, plus a lifetime payout estimate through age 85.

The Formula

AIME = (Sum of highest 35 years of wage-indexed earnings) / 420 | PIA = 90% of first $1,286 of AIME + 32% of AIME from $1,286 to $7,749 + 15% of AIME over $7,749 | Benefit at claim age = PIA x adjustment factor for early or delayed retirement

The SSA takes your 35 highest years of earnings (indexed to the national average wage index through the year you turn 60), sums them, and divides by 420 months to get the AIME. The PIA formula then applies three replacement rates to portions of the AIME. For 2026, the first $1,286 is replaced at 90%, the band from $1,286 to $7,749 at 32%, and anything above $7,749 at 15%. The bend points make Social Security progressive: low earners get a higher replacement rate. Claiming before Full Retirement Age reduces the PIA by 5/9 of 1% per month for the first 36 months early and 5/12 of 1% for each month beyond that. Claiming after FRA adds 8% per year (2/3 of 1% per month) up to age 70.

Step-by-Step Example

Enter your birth year

A worker born in 1965 has a Full Retirement Age of 67 (anyone born 1960 or later has FRA 67).

Enter average annual earnings

Average of your 35 highest years in 2026 dollars: $75,000. Capped at the 2026 taxable maximum of $184,500.

Choose your claim age

Claiming at 67 (FRA) pays the full PIA. Claiming at 62 pays about 70% of PIA. Claiming at 70 pays about 124% of PIA.

Review the estimate

At $75,000 average earnings, AIME is $6,250. PIA = 90% of $1,286 + 32% of $4,964 = $1,157 + $1,588 = $2,745/month at FRA. At 62: about $1,922. At 70: about $3,404.

Real-World Use Cases

Retirement Timing Decision

Workers within 10 years of retirement compare lifetime payouts at 62, FRA, and 70 to decide when to claim, factoring in life expectancy, spousal benefits, and other income sources.

Replacement Rate Planning

Pre-retirees compare their estimated Social Security benefit to their pre-retirement income to see what percentage of their income will be replaced and how much they need from savings.

Spousal Benefit Coordination

Couples use the estimator on both spouses earnings to coordinate claim ages, since a lower-earning spouse may claim on their own record first and switch to a spousal benefit later.

Common Mistakes to Avoid

Assuming your benefit is based on your last few years of earnings. Social Security uses your highest 35 years, indexed for wage growth through age 60. Years with zero or low earnings drag down the average if you have fewer than 35 years of covered earnings.
Ignoring the taxable maximum. Earnings above $184,500 in 2026 do not count toward the AIME and do not generate Social Security payroll tax. High earners should not count salary above the cap in their average.
Forgetting that claiming at 62 is a permanent cut, not a temporary one. Claiming at 62 instead of FRA reduces your benefit by roughly 25% to 30% for life. The reduction does not end at Full Retirement Age.
Overlooking the earnings test before FRA. If you claim before FRA and keep working, benefits are reduced by $1 for every $2 earned above $24,480 in 2026 (and $1 for every $3 above $65,160 in the year you reach FRA). This is recovered later, but it changes near-term cash flow.
Assuming the estimator is exact. It uses a simplified AIME approximation. Your actual benefit depends on your full earnings record, which you can verify at ssa.gov/myaccount. The SSA official estimate is the authoritative number.

Frequently Asked Questions

What is the maximum Social Security benefit in 2026?

The maximum monthly benefit for a worker retiring at Full Retirement Age in 2026 is $4,152, up from $4,018 in 2025. To get this, you must have earned at or above the taxable maximum for at least 35 years. The average retired worker benefit in January 2026 is about $2,071 after the 2.8% COLA.

What is Full Retirement Age?

Full Retirement Age is 67 for anyone born in 1960 or later. For those born 1943 to 1954, it is 66. It rises in 2-month increments for birth years 1955 through 1959. Claiming before FRA reduces your benefit permanently; claiming after FRA up to age 70 increases it by 8% per year.

How is the 2026 COLA calculated?

The COLA is based on the percentage increase in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the third quarter of the prior year to the third quarter of the current year. For 2026, the increase was 2.8%, raising the average retired worker benefit by about $56 per month.

Are Social Security benefits taxed?

Up to 85% of benefits can be subject to federal income tax if your combined income (adjusted gross income plus nontaxable interest plus half of Social Security benefits) exceeds $25,000 for individuals or $32,000 for couples. These thresholds are not indexed for inflation, so more retirees pay tax on benefits each year.

Can I work and collect Social Security at the same time?

Yes, but if you are below Full Retirement Age, your benefits are reduced by the earnings test: $1 for every $2 above $24,480 in 2026. In the year you reach FRA, the reduction is $1 for every $3 above $65,160. After FRA, there is no earnings limit. Reductions are not lost forever; they are added back to your benefit at FRA.

Accuracy and Disclaimer

This estimator uses the 2026 Social Security formula, bend points ($1,286 and $7,749), taxable maximum ($184,500), and 2.8% COLA. It approximates the Average Indexed Monthly Earnings from a single average earnings figure rather than computing it from your full 35-year indexed earnings record. Your actual benefit may differ. The authoritative estimate is available in your my Social Security account at ssa.gov/myaccount. This tool is for planning purposes and is not affiliated with the Social Security Administration.

Conclusion

Knowing your Social Security benefit at each claim age is the foundation of retirement planning, because the difference between claiming at 62 and 70 can exceed $1,400 per month for life.
