Manually calculate shipping cost value

To do these calculations yourself, first must have your shipping cost matrix provided to you by your supplier/freight company.

The formula to calculate the shipping cost per centimeter squared based on a defined cost per measurement is as follows.

COST PRICE / (WIDTH CM x HEIGHT CM)

For the current size range, you are editing the price formula; you should match the range limit value with the step in your shipping cost matrix and retrieve the cost price value.

E.g. You have set a max size range that was 75cm, and in the shipping cost matrix, you have found the cost price for 75cm by 75cm to be a value of $98.00

Dimensions:
75cm by 75cm

Price:
$98.00

Calculation:
98 / (75*75) = $0.017 per centimeter
