Social Security retirement benefits are increased by a certain percentage depending on date of birth if you delay your retirement beyond full retirement age
I see. Another question,  Do you have delinquent retirement credits?  . What if my spouse already receives benefits?
ask them what their benefit would be if it started at their full or normal retirement age, Divide this amount in half and round down to the nearest dollar .This is your estimated spouse 's benefit if you retire at full retirement age
