You will find the total payout amount that you will make on every rental, in the rental details of each trip. This is shown in several places. To see your commission, follow these steps:
Select My Rentals from the site menu
The total of your payout is shown for every rental on the My Rentals page
To see a detailed breakdown of your payout, click 'Rental Details'
Click 'Show Details' or 'Show Payout Info'
This pop-up will show the complete breakdown
You will only see the totals for items that you earn commission on, so insurance and taxes will not be included on your payout breakdown.
