9. Overlooking the Power of COLA Compounding

Cost-of-Living Adjustments (COLA) exist to protect retirees from the corrosive effects of inflation. Every year, the administration adjusts benefit payouts based on the Consumer Price Index. Because these adjustments are percentage-based, the initial baseline amount you secure when you first claim dictates the actual dollar value of every subsequent COLA for the rest of your life.

Consider two retirees experiencing a hypothetical 3 percent COLA. Retiree A claimed early and has a base benefit of $1,500. Retiree B delayed claiming and secured a base benefit of $2,500. A 3 percent increase gives Retiree A an extra $45 per month. The exact same percentage increase gives Retiree B an extra $75 per month. Over a twenty-year retirement period, compounding interest magnifies this disparity enormously. Delaying your benefit does not merely increase your initial check; it massively amplifies the dollar amount of every inflation adjustment you will ever receive.
