Social Security is a federal insurance program that has been operating in the United States since 1935. The program was created during the Great Depression to provide financial support to older adults, people with disabilities, and survivors of deceased workers. Today, Social Security serves as one of the most important sources of retirement income for millions of Americans.

The program operates through a system where workers and employers contribute money into a trust fund through payroll taxes. These contributions are called FICA taxes, which stands for Federal Insurance Contributions Act. When you work, you see these taxes deducted from your paycheck. Self-employed individuals pay both the employer and employee portions of these taxes.
Social Security is designed to replace a portion of your income when you reach retirement age, become disabled, or if you are a family member of a deceased worker. The amount you receive is based on your work history and earnings record. The program tracks your earnings throughout your working years and uses this information to calculate your monthly benefit amount.
According to the Social Security Administration, approximately 67 million people receive Social Security payments each month. This includes about 46 million retirees, 10 million people with disabilities, and 8 million survivors. The average monthly benefit for a retired worker in 2024 is around $1,907, though this amount varies based on individual circumstances.
The program has three main types of benefits: retirement benefits, disability benefits, and survivor benefits. Understanding which type applies to your situation is important for learning about what monthly payments might look like and when you could potentially start receiving them.
Practical Takeaway: Social Security is a self-funded insurance program supported by worker and employer contributions. Your benefit amount depends on your specific work history and the type of benefit for which you may be considered. Learning the basics helps you understand how the program functions and what information you might need to gather.
Your Social Security benefit amount is based on a calculation that considers your highest 35 years of earnings. The Social Security Administration uses a formula that adjusts your past earnings for wage inflation, then calculates your Average Indexed Monthly Earnings (AIME). This figure forms the basis for your Primary Insurance Amount (PIA), which is your full retirement age benefit amount.

The benefit calculation uses a bend point formula that applies different percentages to different portions of your AIME. This formula is designed so that workers with lower lifetime earnings receive a larger percentage of their average earnings as a benefit, while higher earners receive a smaller percentage. For 2024, the formula applies 90 percent to the first $1,174 of your AIME, 32 percent to earnings between $1,174 and $7,078, and 15 percent to earnings above $7,078.
Your earnings record is crucial to this calculation. Social Security maintains a record of your annual earnings, and you can review this record for accuracy. If you find errors, you can request corrections. The Social Security Administration recommends reviewing your earnings record every three to four years to catch any mistakes early, as there are time limits for correcting errors.
Several factors influence your final payment amount beyond just your earnings history:
Cost-of-living adjustments are made annually to help benefits keep pace with inflation. In 2024, beneficiaries received a 3.2 percent increase to their monthly payments. The exact percentage varies from year to year based on changes in the Consumer Price Index. These adjustments help maintain the purchasing power of your benefits over time.
Practical Takeaway: Your benefit amount comes from a specific formula based on your 35 highest-earning years. Reviewing your earnings record for accuracy and understanding how age and other factors affect your payment amount will help you plan more effectively for your financial future.
Social Security retirement benefits are the most common form of benefit paid by the program. Your full retirement age is when you can receive your full benefit amount without any reduction. However, your full retirement age is not the same for everyone—it depends on your birth year.

For people born in 1943 through 1954, the full retirement age is 66. For those born between 1955 and 1960, the full retirement age gradually increases from 66 and two months to 67 years old. For people born in 1960 or later, the full retirement age is 67. This gradual increase was implemented to account for increasing life expectancy.
You have the option to begin receiving retirement benefits before reaching your full retirement age, as early as age 62. However, starting benefits early results in a permanently reduced monthly payment. The reduction percentage depends on how many months early you begin. For someone with a full retirement age of 67, starting at 62 would result in approximately a 30 percent reduction in the monthly benefit amount.
Conversely, you may delay starting benefits past your full retirement age. Each month you delay, your benefit amount increases by approximately 0.67 percent. This means that if you wait until age 70 to start benefits, you could receive as much as 24 percent more per month than you would receive at your full retirement age. This increase continues until age 70, after which no additional increases occur.
The decision about when to start benefits involves personal considerations such as your health, family longevity patterns, current financial needs, and other sources of income. Here are some factors people often consider:
If you continue working while receiving benefits before your full retirement age, your benefits may be temporarily reduced. In 2024, for each $2 earned over the annual earnings limit of $23,400, your benefit is reduced by $1. This reduction only applies until you reach your full retirement age. Once you reach full retirement age, there is no earnings limit, and you receive your full benefit regardless of how much you earn.
Practical Takeaway: Your full retirement age determines your baseline benefit amount, and you can start receiving retirement benefits as early as 62 or as late as 70. Understanding how your age choice affects your monthly payment amount helps you make decisions that align with your personal circumstances and financial planning.
Beyond retirement benefits, Social Security provides two other categories of benefits: Social Security Disability Insurance (SSDI) and Survivor Benefits. These programs serve important functions for workers who experience unexpected life changes.

Social Security Disability Insurance provides monthly payments to workers under full retirement age who have a medical condition expected to last at least 12 months or result in death. The program also may provide benefits to certain family members of disabled workers. The average monthly SSDI payment in 2024 is approximately $1,550 for a disabled worker, though amounts vary based on the individual's earnings record.
To receive SSDI, you must have earned sufficient work credits through your employment history. The number of work credits needed depends on your age. Generally, you need 40 work credits with at least 20 earned in the 10 years before becoming disabled. One work credit is earned for each $1,632 in covered earnings in 2024 (this amount changes annually).
Survivor benefits are paid to family members of a deceased worker who had sufficient work credits at the time of death. These benefits recognize that workers have families who may depend on their income. Survivor benefits may be paid to:
