Net rate
A net rate is what actually lands in your pocket after a channel takes its share. If a guest pays €100 (the gross rate) on an OTA charging 18%, your net rate is €82.
Thinking in net terms keeps comparisons honest. A direct booking at €95 can beat an OTA booking at €100, because there's no commission to subtract. It's the net figure, not the headline price, that tells you which channel pays best.
