Delaying Social Security to 70 Boosts COLAs, Not Just Benefits
Waiting until 70 to claim Social Security raises your monthly check — and quietly supercharges every future cost-of-living adjustment too.
Most retirement discussions obsess over Social Security's looming funding shortfall. Fair enough — it's a real threat. But there's a quieter math problem hiding in plain sight that could hit your wallet just as hard, and almost nobody's talking about it.
Here's the play: delay your Social Security claim until age 70 and you score a bigger monthly benefit. You already knew that. What you might be sleeping on is that every cost-of-living adjustment — your annual COLA raise — gets calculated as a percentage of that larger base. Bigger base, bigger COLA dollar amount, every single year for the rest of your life.

Think about what that compounds to. If inflation runs hot — and recent years proved it absolutely can — that gap between the early-claimer and the late-claimer widens faster than most spreadsheets show. The person who grabbed benefits at 62 gets a COLA applied to a smaller number. You, the patient one who waited until 70, get the same percentage applied to a much fatter base. That's a structural advantage that quietly grows with every passing year.
The conventional wisdom frames the delay decision purely as a breakeven calculation — how long do you have to live to "win"? That framing undersells it. The COLA multiplier effect means the late-claimer's edge accelerates in inflationary environments, not just over long lifespans. Longevity plus inflation is a one-two punch that punishes early claimers more than the simple breakeven math suggests.
Bottom line: if you can afford to wait, the case for delaying to 70 is stronger than the headline numbers let on. The COLA kicker is the hidden return on patience that the retirement industry isn't marketing loudly enough. Continue reading at MarketWatch.com.
