Admob payout per 1000

For context, I'm planning to release an app very soon and I'm thinking of adding ads for a reason I can't specify. I'm having an issue trying to find a good estimate for how much 1000 clicks on a rewarded ad and how the percent cut is. I HEARD THAT GOOGLE TAKES 40 percent but I coundlt find out the the range given by them in the website is before or after cut.
