#8. Is It Always Best to Wait Until Age 70 to Claim Social Security?

Dear Rusty: I’m 66 years old and still (self) employed as a home builder. I have not taken Social Security benefits yet, and don’t need to at this time. If relevant, my business struggled when I first started it five years ago, but did well last year, and I’ll have my highest earning year in my life this year and possibly next year as well. My question is, and it may be dumb, is it always best to delay Social Security until age 70 if there is no current financial need for it? Also, are benefits calculated by total dollars earned over a lifetime, or is some kind of average or mean computation used? I’ve enjoyed excellent health throughout my life, and I have longevity in my family. I’m single if that’s relevant. Signed: Planning Ahead
