Deadhead Break-Even Calculator
A load board offer is two numbers brokers keep apart on purpose: what it pays, and how far you run empty to get it. This puts them back together. It costs the empty leg at empty-truck fuel burn, ignores miles you were repositioning anyway, and tells you the longest deadhead this load can carry before it goes underwater. Runs in your browser. Numbers stay on your machine.
The number that matters is the one brokers split apart
A broker pitches the linehaul and the deadhead as two separate facts. You don’t run them separately. The big number on the result card is the all-in rate per total mile: every dollar the load pays divided by every mile the truck turns to earn it, empty included. That is the real rate. A $1,000 load on 500 loaded miles looks like $2.00 a mile until you add 180 deadhead miles to reach it, and it’s actually $1.47.
Empty miles don’t burn loaded fuel
An empty truck is lighter and burns less. This calculator costs the deadhead leg at your empty MPG, not your loaded MPG. Most deadhead math online gets this wrong and uses one blended number, which overstates the cost of going to get a load and talks operators out of freight they should take.
The miles you’d run anyway are free
If 120 of a 180-mile deadhead is just you heading home for a reset, that’s a trip you were making with or without this load. It is not a cost of the load. Enter those miles in the “run anyway” field and they drop out of the break-even. This is the input no other deadhead calculator has, and it’s the difference between turning down a good repositioning load and taking it.
Why fuel price gets its own field
Diesel is the input that moves weekly and the one squeezing one-truck operators hardest right now. A dollar a gallon swing at 6 MPG is about $0.17 on every mile, loaded and empty. Don’t trust a stale default. Put in what the pump charged you this week, every time you run this.
Read the verdict, not just the rate
The result card names the constraint that’s binding: below your floor, clears cost but the hourly is worse than sitting, or a clean take. Use the max-deadhead figure as a standing rule. Once you know this load can carry 140 empty miles and the dispatch is 190 out, you don’t need to run the math again. You pass.
