Fees Percentage?

Hey, been on Rover for some time now, but I can never tell the exact percentage in fees they take? Anyone know the actual percentage(s)?

Every internet search I've done has given me multiple different answers from 5%, 20-25%, or even 40% (which is crazy)

Also, this subreddit is freaking super helpful btw, I love it! (The taxes help section is fantastic!)

EDIT: I do already know that sittings that are booked will show the amount in fees that are taken, to those telling me that. I'm just trying to calculate one that is coming up as it's not officially booked yet with one of my regular clients as it's a pretty big amount. I wanted to be sure of the actual percentage so my landlord knows I'll have "X" amount for rent lol
