Does my monthly payout increase incrementally if I retire at 63 or 64 or 65?

Yes, each month makes a difference so retiring at 62 years 1 month you get more than retiring at 62 even. It increases 7.5% a year so if you retire a year later you get 7.5% more. When you are over your FRA you start getting 8% to wait until you are 70.

When you are over 60 start planning what is best for you. I applied at 66 to collect based on my late ex husband's record so collect half of his then will switch to mine at 70. Some couples do file and suspend so one can collect on the other's record then let their grow. Laws are changing they are doing away with file and suspend probably. Your financial adviser can probably help you decide how to collect and when, SS isn't allowed to help you maximize your benefits.

Yes.

There is a calculator at

https://www.socialsecurity.gov/OACT/quickcalc/earl...

that allows you to calculate the percentage change in your payout depending upon when you choose to start collecting social security. You simply enter your birthdate and when you choose to start collecting.

If you can, you should wait until it maxes out at 70. If you are married it's possible you could collect on your wife's account until you reach 70. That's what I did.

payout from what? social security or pension? Probably.
