What is CPE?

CPE is the average price of each engagement on a paid social post. It suits community and consideration goals, but watch which actions count, since a save and a like are not worth the same.

Worked example

If spend is $1,800 and engagements is 5,400, then CPE = $0.33.

CPE = Spend ÷ Engagements

Tactical application guide

CPE links spend and engagements in a fixed ratio, so any two pin down the third. Planning backwards is where it earns its keep: enter the spend you have and the CPE you are targeting, and the solver tells you the engagements you must secure. Or lock engagements and CPE from a benchmark to see the spend that plan implies before you commit.
