Social Security Break-Even Calculator

The break-even age is the year of life at which cumulative benefits from delaying claiming equal cumulative benefits from claiming earlier. For most people: claiming at 62 vs 67 break-even is around age 78. Claiming at 67 vs 70 break-even is around age 82. If you expect to live past those ages, delaying wins; if not, claiming early wins. Health, family longevity, and other income sources should all factor in.

Claiming at age 62 with a Full Retirement Age of 67 reduces your benefit by 30% PERMANENTLY. Claiming each month between 62 and FRA increases the benefit; claiming each month after FRA up to age 70 adds 8% per year (delayed retirement credits). There is no benefit to delaying past age 70 - the credit stops accruing.

Up to 85% of your Social Security benefit can be subject to federal income tax. The "provisional income" calculation determines the taxable portion: if AGI + tax-exempt interest + half of SS exceeds $34,000 (single) or $44,000 (MFJ), 85% of benefits are taxable. Below the lower thresholds ($25K single / $32K MFJ), benefits are tax-free. Some states also tax SS benefits.

Yes - there are several married-couple-specific strategies. The higher earner should generally delay to 70 if possible because their benefit also determines the survivor benefit. The lower earner can claim earlier for cash flow. Spousal benefits (up to 50% of partner's FRA benefit) and survivor benefits (up to 100%) add complexity. A bad single-claim decision can cost a couple six figures over their lifetimes.
