Enter the left-rear weight (lbs), the right-front weight (lbs), and the total car weight (lbs) into the Cross Weight Calculator. The calculator will evaluate the Cross Weight. 

Cross Weight Formula

The following formula is used to calculate the Cross Weight. 

CW = (LR + RF) / CW * 100


  • CW is the Cross Weight (%)
  • LR is the left-rear weight (lbs) 
  • RF is the right-front weight (lbs) 
  • CW is the total car weight (lbs) 

To calculate the cross weight, sum the left-rear and right-front weights, divide by the car weight, then multiply by 100.

How to Calculate Cross Weight?

The following two example problems outline the steps and information needed to calculate the Cross Weight.

Example Problem #1

  1. First, determine the left-rear weight  (lbs).
    • The left-rear weight  (lbs) is calculated to be : 500.
  2. Next, determine the right-front weight (lbs).
    • The right-front weight (lbs) is measured to be: 600.
  3. Next, determine the total car weight (lbs).
    • The total car weight (lbs) is found to be: 2000.
  4. Finally, calculate the Cross Weight using the formula above: 

CW = (LR + RF) / CW * 100

The values provided above are inserted into the equation below and computed.

CW = (500 + 600) / 2000 * 100 = 55.00 (%)

Example Problem #2

The variables required for this problem are provided below:

left-rear weight  (lbs) = 500

right-front weight (lbs) = 400

total car weight (lbs) = 3000

Test your knowledge and check your answer with the calculator.

CW = (LR + RF) / CW * 100 = (%)
