does when he starts getting benefits matter as to what he will get? like if he is not at full retirement age
If he begins receiving benefits between age 62 and his full retirement age ,the amount will be permanently reduced by a percentage based on the number of months up to his full retirement age .If your husband is under full retirement age I can give you more info.
OK, but another thing, if my benefits are higher he gets a percentage or what?
He will get an additional amount on your record so that the combination of benefits equals that higher amount .
