Social Security Basics: What You Need to Know

How Social Security works, when to claim, and how it fits into your retirement plan.

How Social Security Works

You pay payroll taxes during your career. In retirement, you receive monthly benefits based on your 35 highest-earning years. It's a safety net—not meant to replace full income.

When to Claim

  • Full retirement age (FRA): 66–67 depending on birth year. Claiming at FRA gives you 100% of your benefit.
  • Early (62): Reduces benefit by ~30%. Permanent reduction.
  • Delayed (70): Increases benefit 8% per year past FRA. Max increase at 70.

Trade-off: Claim early = more years of payments but smaller. Claim late = fewer years but larger payments. Break-even is typically around 78–80.

What Affects Your Benefit

  • Earnings history (35 highest years)
  • Claiming age
  • Working while claiming (before FRA can reduce benefits)
  • Spousal/survivor benefits

Role in Retirement

Social Security typically replaces ~40% of pre-retirement income for average earners. You'll need other savings (401k, IRA, pension) to maintain your lifestyle.

Practical tip: Create an account at ssa.gov to see your estimated benefits. Use that in your retirement planning.
