Sheet 1: Cost per Mile

Type your monthly fixed costs (truck and trailer payments, insurance, ELD, permits), miles per month, working days, diesel price, loaded and empty MPG, and maintenance per mile into the yellow cells. It calculates:

Sheet 2: Load Log

One row per load: rate, empty miles to pickup, loaded miles, empty miles after delivery, days, tolls. It fills in fuel, maintenance, fixed cost, net profit, profit per day and profit per mile using your numbers from sheet 1. After a month you can see which loads and which delivery areas really paid.
