TripAdvisor Vacation Rentals charges hosts a commission of around 3% per booking, which is significantly lower than Booking.com (around 15%) or Expedia (15-25%). Airbnb's host fee is also around 3%, though guests pay a separate service fee on top. Lower fees do not always mean more income, as platforms with smaller audiences may generate fewer bookings. Comparing platforms on net income per booking rather than headline fee alone gives a more accurate picture.
