Social Security Break-Even Age Calculator — When to Claim at 62, FRA, or 70

Your Social Security benefit is based on your Primary Insurance Amount (PIA) — the monthly amount you'd receive at exactly your Full Retirement Age. Every other claiming age is calculated as a percentage of PIA:

Before FRA (early claiming):

• Each of the first 36 months before FRA: benefit reduced 5/9% per month
• Each additional month before FRA beyond 36: reduced 5/12% per month
• Maximum reduction: claiming at 62 with FRA 67 = 60 months early = 30% reduction (70% of PIA)

After FRA (delayed claiming):

• Each month after FRA: benefit increased 2/3% per month (8% per year)
• Increase applies from FRA up to age 70 only (4-year maximum = 32% increase for FRA 66, 24% for FRA 67)

Break-even formula:

Break-even age = (Monthly_A × ClaimAge_A − Monthly_B × ClaimAge_B) / (Monthly_A − Monthly_B)

The higher your PIA, the higher the absolute dollar stakes — but the break-even age is the same regardless of your PIA. Your health, other income, and spousal situation determine the optimal claiming age.

Use this calculator when:

• Planning your Social Security claiming strategy — See the exact monthly amounts at each possible age and the break-even ages between strategies.
• Evaluating early retirement — If you retire at 62, quantify what claiming early vs. bridging to FRA or 70 costs in lifetime benefits.
• Modeling spousal survivor benefits — The higher earner's decision determines the survivor benefit. This calculator shows the monthly amounts the survivor would receive under different claiming ages.
• Stress-testing life expectancy scenarios — The cumulative benefit table shows total lifetime SS income at ages 80, 85, and 90 for each claiming strategy.
• Deciding whether to collect SS while still working — If you claim before FRA while still earning wages, SS may withhold some benefits (earnings test). This calculator quantifies what you'd collect.
