What you are buying, what the refund is, and what a cost-per-mile number can and cannot tell you.
Last updated 17 September 2026.
Net Per Mile is a spreadsheet workbook for owner-operators, sold as a one-off digital download. It is a tool you fill in with your own figures. It is not a service, not a subscription unless you separately buy one, and nobody is doing your bookkeeping for you.
The calculator on this site is free and stays free.
30 days, no argument. Use it for a month. If it does not show you something about your own business you did not already know, email netpermile@gmail.com and you get your money back. You do not have to justify it and you do not have to send the file back.
Every figure the calculator and the workbook produce is an estimate built from the numbers you type in. Put in a wrong MPG and you get a wrong cost per mile. The arithmetic is correct; the inputs are yours.
Buy it once, use it for as many trucks as you run. Please do not resell it, redistribute it, or post the file publicly — it is a small operation and that is the whole business.
Checkout is handled by Gumroad and is subject to their terms as well as these. Card details never reach this site.
Optional, unsubscribe in one click, and the link works immediately. What it collects is set out on the privacy page, including the fact that your calculated figures are sent along with your address.
This is a one-man operation. The site may be down occasionally and the calculator is provided as-is. If the workbook file ever fails to deliver, email me and I will send it directly.
To the extent the law allows, liability is limited to what you paid. If you bought the $97 workbook, that is the ceiling. Nothing here limits any right you have that cannot be limited.
These terms are governed by the laws of the Commonwealth of Pennsylvania, United States.
