I am trying to apply in the real world what I’ve learned from TVM chapter. I wanted to figure out what formula I could use to determine whether or not to take social security at 66, or wait until 70 years old. If taken at 66 with $1268 monthly payments and invested at a given annual rate of 2% is better than if taken at age 70 with monthly payments of $1968 and also invested at a given annual rate of 2%? Should this be calculated as a perpetuity? or should I use an arbitrary number of years to just get an understanding of what the better option is?
Thank you for any help
