There are only two models
Almost every dispatch service in the US charges one of two ways, and most will offer you both.
Percentage of linehaul. You pay a share of what the load pays. Typical market range is roughly 3–10%, clustering around 5%. You pay nothing on a week the truck does not move, which is the whole appeal.
Flat weekly per truck. A fixed figure per truck per week regardless of revenue. Market rates commonly sit somewhere between $150 and $250 per truck. Predictable, and it stops costing you more simply because you had a good week.
Those ranges are what the market broadly does, not a quote. Ask any dispatcher for their actual numbers in writing before you sign anything.
Working out which is cheaper for you
The break-even is simple arithmetic. Divide the flat weekly rate by the percentage rate to find the weekly revenue where they cost the same.
- Flat $200/week against 5% — break-even is $4,000 of weekly linehaul.
- Run above $4,000 a week and flat is cheaper.
- Run below it, or miss weeks, and percentage is cheaper.
A truck grossing $6,000 a week pays $300 on 5% but $200 flat — flat saves $5,200 a year. The same truck having a bad month, or sitting for a fortnight with a blown turbo, pays nothing on percentage and $400 on flat.
So the real question is not which rate is lower. It is how consistent your weeks are. Consistent high-revenue weeks favour flat. Variable weeks, seasonal freight, or a single truck that occasionally sits favour percentage.
What you should be getting for it
At 5% of a $6,000 week, you are paying about $300 for the dispatch. For that to make sense, the dispatcher has to be worth more than $300 a week to you — in better rates, fewer empty miles, or hours you get back.
That is a low bar for a good dispatcher and an impossible one for a bad one. One properly negotiated load a week, or one avoided deadhead run, usually covers it. A dispatcher who simply books whatever is on the board at the posted rate does not.
Ask what they will do about your rate floor, and what happens on a week when the freight is bad. The answer tells you which kind you are talking to.
