Social Security Estimate Calculator

Social Security retirement benefits are calculated using your highest 35 years of indexed earnings. The Social Security Administration (SSA) uses a formula based on your Average Indexed Monthly Earnings (AIME) to determine your Primary Insurance Amount (PIA).

Step 1: Calculate AIME AIME = Sum of 35 highest indexed annual earnings / (35 × 12)

If you worked fewer than 35 years, the missing years count as $0, which significantly reduces your AIME.

Step 2: Apply Bend Points to AIME (2026 values) The PIA formula uses progressive “bend points”, so the first dollars you earned are replaced at a higher rate:

Example Calculation: For AIME of $5,000/month:

• 90% × $1,286 = $1,157.40
• 32% × ($5,000 − $1,286) = $1,188.48
• PIA = $2,345.88/month (at Full Retirement Age)

Step 3: Adjust for Claiming Age Your benefit changes based on when you start collecting. The reduction is not a flat percentage per year: it is 5/9 of one percent for each of the first 36 months you claim early, then 5/12 of one percent for every month beyond that. The table below is the exact factor this calculator applies, not a range, which is why claiming a year early costs 6.67% but claiming five years early costs 30% rather than 33%.

Full Retirement Age (FRA): For anyone born in 1960 or later, FRA is 67. Each year you claim before FRA reduces your monthly benefit permanently. Each year you delay past FRA (up to age 70) adds 8% per year in delayed retirement credits.

Maximum Monthly Benefits (2025, the last full year published):

Reaching these takes 35 years at or above the taxable maximum wage, which almost nobody manages. They lag the bend points above by a year because the SSA publishes them each autumn.

That taxable maximum is $184,500 for 2026, and it is the reason a maximum benefit exists at all. Pay above it is not taxed for Social Security and earns no credit toward a benefit, so a $400,000 salary and a $184,500 one build exactly the same AIME. The calculator caps your entry there and tells you when it has.

One honest caveat about the top of the range. Feed the cap in for all 35 years and this calculator returns roughly 8% more than the published maximum. That is the simplification talking: the real sum uses each past year’s own taxable maximum indexed to average wages, and those indexed figures come in a little under today’s cap. The gap only shows up for someone at or near the ceiling for a whole career. In the middle of the range, where nearly everyone is, the two agree closely.

Key Factors: The average Social Security benefit in 2025 is approximately $1,976/month. Benefits are adjusted annually for inflation via Cost-of-Living Adjustments (COLA). Social Security is designed to replace about 40% of pre-retirement income for average earners. Higher earners see a lower replacement rate, while lower earners see a higher rate due to the progressive bend point formula.

Spousal Benefits: A spouse can receive up to 50% of the higher-earning spouse’s PIA, or their own benefit, whichever is larger. Survivor benefits can be up to 100% of the deceased spouse’s benefit.

Working While Collecting: If you claim before FRA and continue working, earnings above the annual exempt amount reduce your benefit by $1 for every $2 you earn over it. That limit was $23,400 in 2025, up from $22,320 in 2024, and it rises with average wages each year. In the calendar year you actually reach FRA the test is far gentler, and from the month you reach FRA there is no earnings penalty at all. Money withheld under the test is not lost either: the SSA recomputes your benefit upward at FRA to give it back over your remaining lifetime, which is the part most write-ups leave out.

What this page counts, and what it does not

Years worked here means years already on your record. The calculator averages those over 35 and fills the rest with zeros, which is exactly what the SSA does, so the figure it gives you is what you have earned so far. It does not assume you keep working.

The Social Security benefit estimator does assume that. Give it your current age as well and it adds every year between now and your claiming age at your current salary, then runs the same bend points, the same reduction and the same delayed credits.
Thirty years at $80,000 claiming at 67 comes to about $2,574 a month here. On that page, for a 55-year-old with twelve years still to work, it is $2,879. The difference is the twelve years, not a disagreement about the formula.
