- Full Retirement Age (FRA) is 67 for anyone born in 1960 or later. Claiming at 62 reduces the benefit by 30% (5/9% per month for the first 36 months, then 5/12% per month). Claiming at 70 adds 8% per year in Delayed Retirement Credits.
- All figures are in nominal dollars. Real Social Security benefits include annual Cost-of-Living Adjustments (COLA), which are not modeled here. Adding COLA would shift all three lines upward equally.
- Time value of money is not applied. A proper break-even analysis would discount future dollars back at an assumed rate. Discounting generally makes waiting less attractive; the raw cumulative totals shown here are the upper bound for the "wait" case.
- Spousal, survivor, and dependent benefits are not modeled. For married couples, the optimal claiming strategy can differ significantly and depends on both spouses' PIAs and health outlook.
- Up to 85% of Social Security benefits may be subject to income tax depending on your combined income. This is not modeled here.
How Social Security timing works
Social Security benefits are based on your Primary Insurance Amount (PIA) — what you'd receive at your Full Retirement Age (67 for people born in 1960 or later). You can claim as early as 62 (with a permanent 30% reduction) or as late as 70 (with an 8% annual increase for each year you delay past 67, for a max 24% increase over your PIA).
The tradeoff is straightforward: claim early and you get smaller checks for longer. Claim late and you get larger checks but for fewer years. The break-even point — the age at which waiting results in more total lifetime benefits — is typically around 80. If you live past 80, waiting was financially advantageous. If you die before 80, claiming early was better. But there are other considerations too: spousal benefits, inflation protection, and the value of guaranteed income.
Why it matters to your money
Social Security is often the largest single guaranteed income stream in retirement. For many households, it covers 30–50% of pre-retirement expenses. Getting the timing wrong can cost tens of thousands of dollars over a lifetime. For married couples, the decision is even more complex because survivor benefits depend on which spouse delays claiming.

Rules of thumb
- Break-even is ~80: If you expect to live past 80, delaying until 70 generally pays more. If health concerns suggest a shorter lifespan, claim earlier.
- 8% annual delay premium is guaranteed inflation-adjusted income: No investment offers a guaranteed 8% tax-adjusted return. Delaying Social Security is effectively buying a larger inflation-indexed annuity.
- Married couples should coordinate: The higher-earning spouse delaying until 70 maximizes survivor benefits for the lower-earning spouse. This is often the most valuable Social Security strategy for married couples.
Frequently asked questions
- When should I claim Social Security?
- It depends on your health, other income, and marital status. Claiming at 62 gives you smaller checks for longer. Waiting until 70 gives you the maximum monthly benefit (8% more per year of delay past full retirement age). The break-even is typically around age 80.
- What is the Social Security full retirement age?
- Full Retirement Age (FRA) is 67 for anyone born in 1960 or later. Claiming before FRA permanently reduces your benefit (up to 30% at age 62). Claiming after FRA increases it up to 8% per year, maxing out at age 70.
- How is my Social Security benefit calculated?
- Your benefit is based on your highest 35 years of indexed earnings. The SSA applies a progressive formula to your Average Indexed Monthly Earnings (AIME) to calculate your Primary Insurance Amount (PIA) — the benefit at full retirement age.
- Will Social Security be around when I retire?
- The SSA's trustees project the trust fund could be depleted around 2035, at which point incoming payroll taxes would cover about 80% of scheduled benefits. Congress has historically acted to adjust benefits or funding before trust fund exhaustion.
