Social Security: When to Claim and What Changes the Math
Social Security is one of the most analyzed financial decisions in retirement planning and one of the most frequently misunderstood.
The Mechanics
Your benefit is based on your 35 highest-earning years, adjusted for inflation. For anyone born in 1960 or later, full retirement age (FRA) is 67.
- Claiming at 62: benefit is ~30% below FRA amount, permanently
- Claiming at FRA (67): full benefit
- Claiming at 70: benefit is 24% above FRA, permanently (8%/year)
The 8% Credit Is Unusual
The Married Couple Dimension
When one spouse dies, the survivor keeps the larger of the two benefits. If the higher earner delays to 70, they maximize not just their own benefit but the lifetime income protection for their partner.
The bottom line
For married couples, the higher earner delaying to 70 is often the single most impactful income-protection decision available.
When Earlier Claiming Makes Sense
- Poor health or family history suggesting shorter-than-average life expectancy
- Social Security is your primary income and cash flow requires earlier claiming
- Other income sources are very limited and you need the money now
What would you do?
Sam was born in 1965. FRA is 67. Estimated FRA benefit: $2,800/month. He's healthy and has assets that could fund a few years of expenses.
Your Move
Create a free account at SSA.gov and access your Social Security statement. It shows your estimated benefit at 62, 67, and 70. Note all three numbers. Then consider: what do your other assets look like as a bridge if you delay?
