The Payout modifier multiplies the amount from the value parameter by the percentage you set. In other words, this is a ROI calculator. ROI = ((revenue - costs) / costs) * 100%
For example: Your conversion value is $5 and you're willing to pay 40% of it for ads. 40% of 5 is 2. ROI = ((5 - 2) / 2) * 100%) = 150% Thus, your ROI will be 150%
⚠️ The conversion value taken from the postback. Therefore, you need to properly set up your conversion tracking.
