Here's the calculator I used: https://www.ssa.gov/OACT/quickcalc/

Using $80k and "Future Dollars" and a birthdate 5/15/60 (62 years ago), I get these:

$1,388 (this is what it will be now)

$2,419 (this is what it WILL be in 5 years)

$3,400 (likewise will be in 8 years)

You probably used a later birthdate. Future dollars are higher than current.

I needed to use future dollars to take into account growth of the three income streams.
