Numbers make this concrete. Say a dispatcher books you a load and the broker's rate confirmation shows $2,000 for a 900-mile run. On an 80% lease split, the math is straightforward:
- Rate con total: $2,000
- Your 80% share: $1,600
- Carrier's 20%: $400 (covers their authority, insurance and back-office)
That $1,600 is your gross before your costs — fuel, tolls, maintenance, and your own pocket. On a 900-mile load, fuel alone might run $450–650 depending on your truck and diesel prices, so the load nets you roughly $950–1,150 before longer-term truck expenses. Run the same math on a $3,000 load and the difference between an 80% and a 70% split is $300 in your pocket — which is exactly why the split number is worth negotiating and getting in writing.
Two things move that number in your favor, and a good dispatcher chases both. First, accessorials: detention pay when a shipper holds you past your free time, layover, and TONU when a load falls apart after you've committed — these belong to you and should show on the rate con. Second, cutting deadhead, because empty miles burn fuel and earn nothing. A load that pays well but sends you 200 miles out of your way to an empty region can net less than a plainer load in a dense freight market.
These figures are for illustration only. Real rates swing with the lane, the season, the freight type and your negotiating. Anyone who hands you a guaranteed weekly number is selling something.
