I took early benefits at 62 with the idea of my wife taking the 50% of my benefit when she turns 62 in March 2014. However, we would now like to delay her benefit until later. I believe that her benefit will keep increasing as a percent of my maximum benefit, but I can't find anything that CLEARLY says that. For example, if I get $1,000 per month now at the early rate, my wife could get $500/mo. if she starts taking at 62. But if she waits until 66 she'd probably be getting $666/mo?
In other words, her benefits are not capped at 50% of my early retirement benefit, but rather on her age at claiming benefits based on my age 66 maximum.
