The most common Social Security question — 'when do I break even?' — is the wrong question. It treats a longevity insurance policy like a casino bet, and it ignores the person the decision matters most to: the surviving spouse.
Break-even is the wrong question
Claiming at 62 versus 70 is usually framed as a gamble on your own lifespan. But Social Security is the only inflation-adjusted lifetime income most households have. The right frame isn't 'when do I get my money back' — it's 'which claiming age gives our household the most guaranteed income if one of us lives to 95?'
What the survivor gets
When one spouse dies, the survivor keeps the larger of the two benefits — and loses the smaller entirely. A higher earner who delays to 70 doesn't just raise their own check; they permanently raise their spouse's survivor benefit, often by $1,000+ a month for life. For couples with an age gap or a health gap, this dwarfs the break-even math.
The coordination play
The classic move still works: lower earner claims earlier to fund the bridge years while the higher earner delays to 70. Those bridge years, conveniently, are often the same low-income years perfect for Roth conversions. Coordinate the two decisions together — never in isolation.
The takeaway
If you're married and within a few years of claiming, model both benefits and the survivor outcome before filing. It takes an hour and it lasts a lifetime.
