Social Security calculates your benefit using your 35 highest-earning years, adjusted for inflation. If you worked fewer than 35 years, zeros are averaged in — which pulls your benefit down. If you had low-earning years early in your career, working a few extra years at higher income can meaningfully increase your benefit.

Your full retirement age (FRA) is the age at which you receive 100% of your calculated benefit. For anyone born in 1960 or later, that's age 67. You can claim as early as 62 — but every month before your FRA permanently reduces your benefit. Claiming at 62 versus 67 can mean a difference of hundreds of dollars per month for the rest of your life.

On the flip side, delaying past your FRA earns you delayed retirement credits — 8% per year, up to age 70. That means someone with a $2,000/month benefit at 67 would receive approximately $2,480/month by waiting until 70. Over a 20-year retirement, that's nearly $115,000 more in lifetime income.

For married couples, the spousal benefit adds another layer of strategy. A spouse who earned less can receive up to 50% of the higher earner's full retirement benefit — even if they have limited or no work history of their own. And survivor benefits mean the surviving spouse keeps the higher of the two benefits after one passes.

Social Security is also partially taxable. Depending on your combined income, up to 85% of your benefit may be subject to federal income tax. This makes claiming strategy a tax decision as much as an income decision.

• ✓Your benefit is based on your 35 highest-earning years — gaps or low-income years reduce it.
• ✓Claiming at 62 reduces your benefit permanently by up to 30% — claiming at 70 increases it by up to 32%.
• ✓Spouses can receive up to 50% of the higher earner's benefit — survivor benefits protect the remaining spouse.
• ✓Up to 85% of Social Security benefits can be taxable depending on your total income.
• ✓Social Security alone is rarely enough — most retirees need additional income sources to maintain their lifestyle.

Let's say your full retirement age benefit (at 67) is $2,200/month. Here's how claiming age changes what you actually receive:

Claim at 62: ~$1,540/month — a 30% permanent reduction. Over 20 years, that's $158,400 less in lifetime income compared to waiting until 67.

Claim at 65: ~$1,980/month — a 10% reduction. Still permanently lower for life.

Claim at 67 (FRA): $2,200/month — your full calculated benefit with no reduction or increase.

Claim at 70: ~$2,728/month — a 24% increase over FRA. Every year you delay past 67 adds 8%. This is the maximum benefit you can receive.

The breakeven point for delaying from 62 to 70 is typically around age 80–82. If you expect to live past that — and most people underestimate their longevity — waiting almost always pays off significantly.

• ✗Claiming at 62 just because you can — it permanently locks in a reduced benefit for the rest of your life.
• ✗Not coordinating spousal benefits — failing to optimize both spouses' claiming strategy leaves significant money on the table.
• ✗Ignoring the tax impact — drawing other income alongside Social Security without a tax strategy can make up to 85% of your benefit taxable.
• ✗Assuming Social Security will cover all your expenses — the average benefit replaces only about 40% of pre-retirement income.
• ✗Not checking your Social Security statement for errors — incorrect earnings records can reduce your benefit without you knowing.
