What a load actually pays at $4, $5, $6 and $7 diesel

The plain math for owner-operators, small fleets and drivers: diesel per mile, your break-even rate, fuel surcharges, empty miles, IFTA and what every 10 cents at the pump costs you.

Every rate is quoted per mile. Diesel should be counted the same way.

A pump price means little until it's turned into a cost per mile, and a rate means little until it's held against your own break-even. This book does both, with tables that work at any diesel price from $3 to $8.

CHAPTER 2
$2.958

The example truck's break-even per paid mile at $5.00 diesel. The book shows you how to build your own in about 15 minutes.

CHAPTER 4
21¢

What the most common fuel surcharge leaves uncovered on every paid mile in the book's example. The base rate has to carry it.

CHAPTER 5
$71.43

The diesel in 100 empty miles at $5.00 and 7.0 mpg, before tires, repairs and your time.

Figures are from the book's worked examples, which use one made-up example truck to show the method.

Same load. Same rate. Different diesel.

A 1,000-mile van load from Chapter 3, paid two ways. On a flat rate, every move at the pump comes out of your pocket. On linehaul plus a fuel surcharge, it mostly doesn't.

$2.25 linehaul + fuel surcharge$2,037.73$2,033.53-$4.20

Example from the book: 1,000 loaded miles plus 176.5 empty miles, 7.0 mpg, surcharge figured the common way, (price - $1.25) ÷ 6.0.

Questions

Is this a printed book?

No. It's a PDF you download right after you pay. It's set on U.S. letter paper and prints cleanly in black and white at home, and you can print the worksheets as often as you like.

Will it go out of date when diesel prices change?

No. The book doesn't print this week's prices. Every table runs from $3 to $8 a gallon and comes with the formula, so you read off the row for this week's price. Chapter 9 shows where to find this week's numbers in five minutes.

What do I need for the calculator?

Microsoft Excel, or free Google Sheets: upload the file to Google Drive and open it with Sheets. It's easiest on a computer.

I'm a company driver. Is it for me?

It's written for owner-operators and small fleets. If you're thinking about leasing on or buying a truck, it shows the math you'll be living with.

How do I get it after I pay?

Gumroad shows the download page right after checkout and emails you a link. You can download the files again any time from that email.

Is this tax or legal advice?

No. It explains the arithmetic and quotes the federal rules on leases, brokers, IFTA and fuel tax. Talk to a tax professional about your own return.
