The payment per download calculation will be done considering the number of downloads and the number of subscribers on that specific month.
This is how your commission from downloads would work:
At the end of each day, we would calculate the total amount of subscription fees and calculate the "per diem" subscription amount. Then we would calculate the total number of downloads. The total daily subscription average would be divided by the number of downloads to calculate the "per file" price for that day. That number would be multiplied by 0.5 to calculate the 50% rate.
What is RPI and what does it stand for?
RPI stands for "Return per Image" and this basically is calculated to know what earnings your overall portofolio is making for every image uploaded. The higher the RPI the better it is. RPI fluctuates depending on various factors such as: number of downloads your images get, acceptance rate and uploading frequency.
