Free trucking calculators that show their math
Every calculator here answers one question a carrier faces every week: does this load pay, what does the truck really cost per mile, is this setup legal on the scale, what will a dispatcher cost. Each one shows the formula, lets you change every assumption, and keeps your numbers on your device. No signup, no email gate.
Rules come from their source, cited on each page with the month we checked them; worked numbers are labeled as examples. Start with a group below, or search for a word like "axle", "fuel" or "fee".

Where to start
New to running your own numbers? Work out your cost per mile first, because every other answer depends on it. Then use the rate per mile calculator on the loads you're offered, and the weight tools before you load anything heavy. If you're deciding whether to hire a dispatcher, the dispatch calculators put the fee and your time on the same page.
