CPI calculator — cost per install from spend and installs

CPI = spend / installs. Zero installs is not a rate.

A missing or zero denominator is an em dash, never a fabricated zero.

How is cost per install calculated?

CPI = attributed spend / attributed installs. Zero installs is not a rate.

What if installs are missing or zero?

A missing or zero denominator is unmeasured. This page prints an em dash — never a fabricated 0, 0%, or $0.00 rate.

Is this a live campaign figure?

No. The figure is computed in this browser from the numbers you typed. A live TrueWave campaign also names the cycle, the counted platforms, and the age of the scrape.

When should a UGC campaign use CPI?

Only when the campaign is actually buying installs and the install count is the invoice denominator.
