Truck Axle Weight Calculations

Truck Scale Calculator is a utility app designed to assist truck drivers in analyzing the weights of their axles.

Federal Limits

It is designed for rigs which are either: 1) 3 axle sets, including steers, drives, and tandems; or, 2) 4 axle sets, including steers, drives, and two different spread axles.


  • It is also designed to input the scale readings from either a short platform or long platform scale. For long scales, it can compute for either "scaling on" or "scaling off" - i.e., gross weight first or last.Once the readings are entered, the app calculates the weights on each axle set and displays them in a summary screen.
  • Then, the user can adjust the fifth wheel toward the front or back, and the steer axle and drive axles weights will be adjusted according to a predefined amount which can be adjusted by the user. For tandem rigs, the user can adjust the tandem slide toward the front or back as well.
  • Does that mean move the on forward or back? Re-label the tabs from plus and minus to forward and back.
  • Take the easiest and most accurate way to get your weights legal!
  • No more scrabbling around for paper & pen (and calculator) with this app, just enter your 1st scale ticket 🎫 weights and hit ‘calculate’ get the results right there, see the results of sliding tandems or 5th wheel forward or back by a single or multiple holes.
  • Simple, accurate and a real time saver, especially if you want to go through the routine of scaling, parking, going inside to get your ticket.

How axle weight limits are determined

Use in conjunction with Cat Scale WeighMyTruck and you’re on your legal way in a fraction of the time! I don’t think it’s that good. Did you get the right app? Thanks very much. This app is amazing worth every penny , it saves me so much time to sit there and calculate everything on a calculator especially when I’m running late somewhere I can just drive up and put in every number right away drive then drive+steer and then whole gross weight , I was looking for a app like this for a while now and this is the only one that I know exist like this every other app wasn’t what I needed !
