US: Social Security basics

Social Security is a US federal program that provides retirement (and disability/survivor) income, funded by payroll taxes during your working years. It's a foundation of most Americans' retirement.

How benefits are earned

• You earn credits by working and paying Social Security taxes; a minimum number qualifies you for retirement benefits.
• Your benefit is based on your highest-earning years and the age you start claiming.

Claiming age matters a lot

• You can start as early as 62, but benefits are permanently reduced.
• Waiting until your full retirement age gives the full benefit.
• Delaying further (up to 70) increases your monthly benefit substantially. Choosing when to claim is one of the biggest retirement decisions, depending on your health, other income, and how long you expect to live.

A foundation, not the whole plan

Social Security is designed to replace only part of pre-retirement income — typically not enough to live on comfortably alone. It's meant to sit alongside personal savings.

Key takeaway

Treat Social Security as the base layer of retirement income, and build 401(k)s, IRAs, and other savings on top. Understand your claiming options — delaying can meaningfully boost lifetime income. Check current rules on the official SSA resources.
