Please explain what "payroll" taxes they are then.
You still haven't addressed the fact that that you stated that someone retiring at 67 would receive $3167 a month? Why is that? Facts make your head hurt? Start answering questions and quit dancing around the truth like a Liberal.
I'm certain Ben will have a better explanation where it all ends up, but here they are:
SS - 6.2% withheld from paycheck
SS - 6.2% company matching portion paid by employer
Medicare - 1.45% withheld from paycheck
Medicare - 1.45% matching portion paid by employer
State unemployment - rate varies, paid by employer
Federal unemployment - generally 0.8% paid by employer; can be higher in some instances.
That is all of them.
