Social Security is a federal program that acts as a safety net for millions of Americans. Think of it as a form of social insurance. While you work, you pay taxes into the system. In return, you and your family receive protection in the form of benefits if your earnings stop due to retirement, disability, or death.

The core of the system is based on credits. As you work and pay Social Security taxes, you earn credits. These credits determine your eligibility for future benefits. In 2024, you earn one credit for each $1,730 of earnings, up to a maximum of four credits per year. The number of credits you need depends on your age and the type of benefit you're applying for.

This is the most common type of Social Security benefit. It's designed to provide a continuing source of income after you stop working. Your benefit amount is based on your average earnings over your working years. Higher lifetime earnings result in higher benefits.

You can start receiving retirement benefits as early as age 62. However, if you start your benefits early, your monthly amount will be permanently reduced. If you wait until your full retirement age (which varies from 66 to 67, depending on the year you were born), you'll receive your full benefit. If you delay collecting past your full retirement age, your monthly benefit will increase, up until age 70.

Social Security isn't just for retirement. It also provides crucial support for workers who become disabled and for families who have lost a primary wage earner.

To receive disability benefits, you must have worked long enough and recently enough to qualify. The exact number of work credits needed depends on your age when you become disabled. Younger workers can qualify with fewer credits.

Survivor benefits are paid to the family of a worker who has died. This can include widows, widowers, and dependent children. The amount of work needed to qualify for survivor benefits depends on the worker's age at the time of death. The younger a person is when they die, the fewer credits they need for their family members to be eligible for benefits.

Understanding these three pillars of Social Security—retirement, disability, and survivor benefits—is the first step in seeing how the program provides a broad foundation of economic security.
