Setting your minimum acceptable rate
Want the tool, not the theory? Run the free calculator →
Your minimum acceptable rate is the lowest all-in rate you can take on a load and still cover every mile you run, plus the profit that makes the trip worth doing. The formula is short: total miles times your cost per mile, plus a target profit. Anything below that number is either a loss or a day of work you gave away.
That one number turns load shopping into a rule instead of a feeling. Offer clears the floor with no red flags? Book it. Comes in a little under? Negotiate. Sits far below? Pass and keep scrolling. The broker never sets your floor. Your costs do.
Two floors: break-even and walk-away
There are really two floors stacked on top of each other. The first is your cost floor, or break-even: total miles times your all-in cost per mile. Haul a load below that line and you are paying to move someone else's freight.
The second is your profit floor: break-even plus the minimum profit that makes the load worth your hours and your truck's wear. The profit floor is your minimum acceptable rate. The cost floor is the line you never cross, even in an ugly market.
Both floors depend on one input you have to get right first: your true cost per mile, with fuel, fixed costs, and your own pay all counted.
The formula, step by step
Count every mile, not just the paid ones. Total miles are loaded miles plus deadhead to the pickup. A 600-mile load with a 75-mile deadhead is a 675-mile job, and your truck burns diesel on all 675 of them.
Setting the floor on a 600-mile van load
Total miles: 600 loaded + 75 deadhead = 675 mi
Cost floor: 675 mi × $1.80/mi = $1,215
Target profit: + $200
Minimum acceptable rate: $1,215 + $200 = $1,415
Quoted per loaded mile: $1,415 ÷ 600 mi ≈ $2.36/mi
Now every offer has something to land against. $1,500 clears the floor and books. $1,300 is $115 short, which is counteroffer territory, not an automatic pass. $1,000 is $415 under, and no amount of phone charm fixes that.
Turn the floor into a per-mile target
Brokers talk in rate per mile, so divide the floor by loaded miles to get the number you quote: $1,415 over 600 loaded miles is about $2.36. Divide by all 675 miles instead and you get roughly $2.10, your effective floor once deadhead is counted.
Before you quote it, sanity-check the lane. LoadMerit's benchmarks show typical lane ranges (index-adjusted reference ranges, not live spot quotes), so you can tell whether a $2.36 floor is realistic where you are or whether repositioning is the better play.
When the floor moves
The floor is not a set-and-forget number. Diesel jumping 25 cents a gallon adds about 4 cents a mile at 6.5 MPG, roughly $26 on the 675-mile example. Recompute and your floor is $1,441, not $1,415.
Extra deadhead moves it more. If the pickup sits 125 miles out instead of 75, that is 50 more miles at $1.80, and the floor climbs $90 to $1,505. Multi-stop loads, toll-heavy lanes, and receivers known for long dock times should push your target profit up before you quote.
Holding the floor on the phone
Your floor is private. Quote above it so you have room to come down and still land at or over $1,415. If the broker's best number sits below your profit floor but above break-even, that is a judgment call: take it only when it repositions you into a stronger market. How to run that call is its own skill — see building a counteroffer.
If nothing on the board clears your floor for days, do not quietly lower it load by load. Check the inputs first: stale fuel prices and bloated deadhead estimates raise the floor artificially. If the inputs are right, the lane is soft, and the honest choice is between flexing the profit floor and repositioning. The cost floor never flexes.
A floor only works if every offer gets measured against it. The free calculator checks one load against your numbers; LoadMerit Copilot keeps your cost profile on file and applies the same floor to every load you enter.
Common questions
- Is my minimum acceptable rate the same as my break-even?
- No. Break-even only covers the cost of running the miles. Your minimum acceptable rate adds a target profit on top, so the load pays you something beyond keeping the truck alive. Break-even is the line you never cross; the profit floor is the line you negotiate from.
- Should my floor change from load to load?
- Yes. Total miles, deadhead, fuel price, and load complexity change with every load, so the floor changes too. Recalculate it per load instead of carrying one flat number all year.
- What should I do when no load clears my floor?
- Check the inputs first: an outdated fuel price or an oversized deadhead estimate inflates the floor. If the math is right and the lane still pays below it, repositioning to a stronger market usually beats hauling sub-floor freight where you sit.
