How does delaying Social Security work as longevity insurance?

Delaying Social Security is one of the cheapest, strongest forms of longevity insurance available. For each year you wait past full retirement age until 70, your benefit grows about 8%, and that larger, inflation-adjusted check is paid for life – exactly the income you want most if you live a long time. Claiming at 62 versus 70 can mean a benefit roughly 76% higher at 70. The tradeoff is spending more from your portfolio in the bridge years, but that's often a wise trade because it converts savings into guaranteed, government-backed lifetime income. Delaying especially protects a surviving spouse, who inherits the larger benefit. If you're in good health and can cover the gap years, waiting until 70 usually pays off.
