Step 1: Gather 5 Key Details
Before committing to a load, confirm these numbers with the broker (or check the rate confirmation):
- Total pay for the load (include fuel surcharge if applicable)
- Loaded miles
- Deadhead miles (miles to the pickup)
- Extras such as tolls or lumper fees
- Fuel cost and your MPG
Step 2: Calculate RPM (Revenue per Mile)
Use this quick formula:
RPM = Total Pay ÷ Loaded Miles
Example: $1,755 ÷ 650 = $2.70 per mile
Step 3: Calculate CPM (Cost per Mile)
A fast way to estimate your costs:
- Fuel cost per mile = Pump price ÷ MPG
- Add $0.60 per mile to cover other expenses (truck payment, insurance, tires, maintenance, ELD, etc.)
- Adjust later with your actual numbers.
Example: $3.85 ÷ 7 mpg = $0.55 fuel/mi → $0.55 + $0.60 = $1.15 per mile
💡 Tip: Always account for deadhead. If you’re driving 100+ empty miles, your real CPM increases—so be selective.
Step 4: Make the YES/NO Decision
- Say YES if: RPM ≥ CPM + $0.40/mi (a solid profit margin)
- Say NO if it doesn’t meet that threshold.
Examples:
- RPM $2.70 vs CPM $1.15 → $1.55 profit/mi → YES
- RPM $1.60 vs CPM $1.15 → only $0.45 profit/mi → likely NO once deadhead/tolls are included
Deadhead Rule of Thumb
- Under 50 miles: Okay
- 50–100 miles: Only if pay is strong
- 100+ miles: Usually not worth it, unless the rate is exceptional
Mini Load Calculator (Keep Handy)
- Pay: ________
- Loaded miles: ________ → RPM = Pay ÷ Loaded miles
- Pump price: ________ ÷ MPG: ________ → Fuel/mi = ________
- Other costs/mi: $0.60 (adjust later)
- CPM = Fuel/mi + Other costs/mi
- Decision: Is RPM − CPM ≥ $0.40/mi? → YES / NO
- Deadhead: ______ miles (adjust decision if high)
3 Quick Tips to Boost Profits
- Reduce deadhead: Choose closer pickups and link drops so the next pickup is nearby.
- Buy fuel smart: Focus on fuel cost per mile (price ÷ MPG), not just the pump price.
- Keep documents clean: Snap BOL/POD at the dock—it speeds up payment.
FAQs
- What’s the difference between RPM and CPM?
- RPM = revenue per loaded mile.
- CPM = your total cost per mile (including deadhead).
- Only book if RPM beats CPM by a safe margin.
- How do I estimate CPM quickly?
- Fuel per mile (price ÷ MPG) + about $0.60 for all other costs. Refine with your own numbers later.
- Do I count deadhead?
- Yes. High deadhead can wipe out profits. Either pass on the load or negotiate higher pay.
You can run these numbers with a notepad. Or, if you want speed and accuracy, Fenderr calculates RPM/CPM (with deadhead included), lets you dispatch by text, and generates invoices quickly. Use it when you’re ready.
