Delaying Social Security Claims Until 70 Increases Lifetime Benefits by Up to $137,280

A worker with a $2,200 monthly benefit at full retirement age who delays claiming Social Security from 62 to 70 can increase total lifetime benefits by approximately $137,280 if they live to age 90. This permanent increase is driven by the mechanism of delayed retirement credits. Every year a worker delays past full retirement age adds 8% permanently to the monthly benefit. Waiting from 67 to 70 locks in a 24% permanent increase.

The SSA reports maximum monthly benefits of $2,969 at 62, $4,152 at 67, and $5,181 at 70. However, the net real gain from Cost of Living Adjustments (COLA) is often lower than the headline figure. Rising Medicare Part B premiums consume more than a quarter of that gain for most enrollees. The net real gain for the average retiree is roughly $38 per month.
