I retired at 58 and live off of my monthly check. I did spend the pay-off for things I wanted at the time. Debbie retired at 60 and gets half of the amount that I get. We haven't touch the 401. It gets a little tight about the end of the month,but we do just fine.
I need 3 tires and 2 or 3 batteries for my boat. Looks like 5 or 6 months of buying one per month before I'll take the boat out.
