This article aims to clarify how the distribution of the cost of freight between the items of a cart when one of these items has a freight promotion works.
Division of shipping cost between items
The shipping cost takes into account the weight of the products added to a cart. These weights are listed on the freight worksheet of a carrier.
When there is more than one item in the cart, the shipping cost divided by each item is proportional to its weight, based on the total weight of the cart.
Let's look at how the cost of shipping calculation would be calculated on a cart with 5 items, with a total shipping cost of 200 currency units:
To find out the cost of shipping a cart, please make shipping simulation. To find out the weight of a SKU, access the Products and SKU page in the Catalog menu and look for Shipping Weight.
- Total Cost of Shipping: 200
- Product A Weight: 20
- Product B Weight: 25
- Product C Weight: 15
- Product D Weight: 10
- Product E Weight: 30
- TOTAL WEIGHT = 100
The calculation of the shipping cost of each item will be given by the following formula:
__ Total Shipping Cost x (Product Weight / TOTAL WEIGHT) __
Applying the above formula, we have:
200 x (20/100) = 40
The * Total Cost of Shipping * is 200. We see that * Product Weight A * represents __20% __ of the total weight of the cart (20 / 100).
Therefore, the * Shipping Cost of Product A * will be 40.
Shipping cost breakdown when there is promotion of freight in the cart
When there is a promotion of freight for some items in the cart, the costing calculation for the shipping cost occurs as described in the previous section.
Let's assume a scenario where Product B receives a promotion of * 10% in the value of your freight *.
Applying the formula, we have:
200 x (25/100) = 50
The * Total Cost of Shipping * is 200. We see that the Poso of Product A represents __25% __ of the total weight of the cart (25 / 100).
Therefore, the * Cost of Shipping of Product B * will be 50.
As product B has a 10% promotion on the value of your freight, the shipping cost will be:
50 - (50 x 10%) = 45
If product B had a Free Shipping promotion, its shipping cost would be zero:
50 - (50 x 100%) = 0
Therefore, to calculate the impact of a freight promotion on the cost of shipping an item, it is necessary to calculate the shipping cost proportional to the weight of the item and apply the discount percentage to this value.
