How does a CPP compare with a CPM for the same station and commercial? The following shows the differences:

CPP
Cost of a thirty-second commercial: $110
Metro rating at 2:00 p.m.: 8
$110/8 = $13.75

CPM
Cost of a thirty-second commercial: $110
Number of households delivered at 2:00 p.m.: 77,000
$110 x 1000/77,000 = $1.43
