• CPI = CPM ÷ (1,000 × CTR × C2I)
• CPA = CPI ÷ Post-Install Rate
How to use these calculations in campaign bidding
If your target acquisition cost is $15 CPA, you can use this formula to reverse-engineer your maximum allowable CPM bid. When optimizing bids with Visprisca, our models calculate these conversions on an impression-by-impression basis rather than using static aggregate averages.
Worked Example (Illustrative):
At a $4.50 CPM with a 1.8% CTR and a 12% click-to-install rate, you receive 2.16 installs per 1,000 impressions. This yields a $2.08 CPI. If 25% of installers make a purchase, your resulting CPA is $8.33.
