The entry fee calculator is located in each stake/level in Setup.
To calculate the entry fee that you should publish everywhere (in your Premium List, at the AKC, and anywhere else you plan to advertise your event), type the amount you want your club to receive per entry in the "Club receives" field. The calculator will show you the PerfDog processing fee and the total amount to be published/charged for that stake or level.
Note: The Electronic Processing Fee works differently from the PerfDog Processing Fee. It's calculated outside of the Premium List Fee (and won't show in the calculator) because the system doesn't pass this fee on to entrants. Instead, it's deducted from the final proceeds sent to your club.
