Your Social Security number is a nine-digit identifier assigned by the government to track your work history and earnings record. The Social Security Administration (SSA) maintains records of every job you've held and the wages you've earned throughout your working life. This information forms the foundation of your Social Security benefits calculation.

When you receive your Social Security number, typically as a child or when you start working, the SSA creates an account in your name. This account is separate from your benefit account and serves as your official record with the agency. Understanding how this system works helps you recognize why keeping your information current matters.
Your earnings record shows the wages you reported to the government through payroll taxes. Each employer sends wage information to the SSA, which stores it in your account. Over time, this creates a complete picture of your work history. The SSA uses this record to calculate how much you might receive in retirement, disability, or survivor benefits.
You should periodically check that your earnings record is accurate. Mistakes can happen—an employer might report wages under the wrong Social Security number, or clerical errors could occur during data entry. If errors aren't corrected, they could affect your future benefits. The SSA allows you to review your earnings record and dispute any inaccuracies you find.
Several types of work history appear on your Social Security record: regular employment, self-employment income, military service, and railroad employment. Each type of work may be counted differently in your benefits calculation. Understanding what appears on your record helps you see the complete picture of your work history as the SSA sees it.
Social Security retirement benefits are not a fixed amount—they depend on how much you've earned throughout your working life and when you choose to start receiving them. The SSA uses a specific formula based on your highest 35 years of earnings. If you've worked fewer than 35 years, the formula includes zeros for missing years, which lowers your average benefit amount.

The calculation process begins with adjusting your historical earnings to account for inflation and wage growth. This means older earnings are adjusted upward to reflect what they would be worth in today's economy. Next, the SSA calculates your Average Indexed Monthly Earnings (AIME) by averaging your highest 35 years of adjusted earnings and dividing by 420 months (35 years).
Once your AIME is determined, the SSA applies a benefit formula that's different for people born in different years. The formula has "bend points"—specific dollar amounts where the percentage used to calculate your benefit changes. Your earnings below the first bend point are multiplied by a higher percentage (90%), while earnings between bend points are multiplied by lower percentages (32% and 15%). This structure means lower earners receive a larger percentage of their pre-retirement earnings, while higher earners receive a smaller percentage.
Your Primary Insurance Amount (PIA) is the benefit you'd receive at your Full Retirement Age. Full Retirement Age depends on the year you were born and ranges from 65 to 67 for people retiring now. Starting benefits before your Full Retirement Age reduces your monthly payment. For every month you delay past your Full Retirement Age (up to age 70), your benefit increases by approximately 0.67% per month, or 8% per year.
For example, a person born in 1955 with a Full Retirement Age of 66 and 2 months might receive $1,500 monthly at their full retirement age. If they start at 62, their monthly benefit might be around $1,050. If they wait until 70, it could be approximately $1,860. These numbers illustrate why the timing of when you start benefits significantly affects your total lifetime payments.
Social Security provides several categories of benefits beyond retirement. Understanding what programs exist helps you recognize what might be available to you or your family members in different circumstances.

Retirement benefits are the most common type. These payments go to workers who reach a certain age and former workers' spouses and children. The amount you receive depends on your earnings record and the age at which you start benefits. Most workers think of Social Security as a retirement program, but it actually provides income protection in several other situations.
Disability Insurance benefits go to workers under Full Retirement Age who have a medical condition expected to prevent them from working for at least 12 months or result in death. The SSA defines disability more strictly than many other programs—the condition must be severe enough to prevent substantial work activity. The amount of disability benefits is calculated similarly to retirement benefits, based on your earnings record.
Survivors benefits provide income to family members of a worker who has died. A widow or widower can receive benefits at Full Retirement Age, or reduced benefits as early as 60 (50 if caring for a child under 16). Unmarried children under 19 (or 22 if in high school full-time) may receive benefits. A dependent parent age 62 or older may also receive survivors benefits. Each family member's benefit is calculated as a percentage of the worker's Primary Insurance Amount.
Supplemental Security Income (SSI) is a different program than Social Security, though both are administered by the SSA. SSI provides monthly payments to people with limited income and resources who are 65 or older, blind, or disabled. Unlike Social Security, SSI is needs-based and funded through general tax revenue rather than payroll taxes. The maximum SSI payment for 2024 is $943 monthly for individuals, though some states add supplemental payments.
Medicare benefits are closely tied to Social Security. Most people become automatically enrolled in Medicare Parts A and B at 65 if they're receiving Social Security retirement or disability benefits. Understanding your Medicare options—including decisions about supplemental coverage or Medicare Advantage plans—is part of planning for retirement alongside Social Security.
The Social Security Statement is a document that shows your earnings record, estimated benefits, and other important information about your account. The SSA sends these statements by mail to people not yet receiving benefits, typically near their birthday. If you create an account on the SSA website, you can view your statement online anytime, rather than waiting for the annual mailing.

Your statement contains several key sections. The earnings record shows your taxable wages year by year throughout your working life. This is crucial to review because it reflects what the SSA will use to calculate your benefits. The statement also includes estimated benefit amounts under three scenarios: if you start at 62, at your Full Retirement Age, and at 70. These estimates help you understand how waiting affects your monthly payment.
The statement lists all family members who may be eligible for benefits on your record. For married people, it shows information about spousal benefits—a spouse may receive up to 50% of your Primary Insurance Amount if they've reached Full Retirement Age, or reduced amounts if they start earlier. If you have dependent children, the statement indicates what their potential benefit might be.
Creating an account on my Social Security (my.ssa.gov) gives you direct access to this information without waiting for mail. You can view your earnings record, check estimated benefits, and update your contact information. The portal also allows you to see your Medicare information and manage your account settings. Creating an account typically requires your Social Security number, email address, and verification of your identity.
