The service fee is the fee drivers/couriers pay Uber, and it varies from trip to trip. It’s the difference between what a rider pays and what a driver earns on a trip, excluding tips, tolls, and certain fees, taxes, and surcharges.
The weekly service fee, for a particular weekly period, is the total amount of service fees a driver paid Uber minus any other payments to that driver that were not included on the per-trip receipt, including but not limited to weekly promotions, cleaning fee payments, and lost item fee payments.
The service fee varies by tripand week, and can sometimes be zero or negative. This can happen if the customer payment is equal to or less than your earnings, such as when a trip takes much longer than expected or due to rider or driver promotions.
