Let's say the fixed shipping fee per item is $2. We can write a simple calculation to multiply the order quantity by 2 to calculate the total shipping fee. We can use the CURRENCY function to display the calculated value as a currency. CURRENCY("$", Order quantity * 2)

Example #1: Let's say the shipping fee for the first item is $10 and for each additional item, the shipping fee is $5. If a user orders 3 items, the shipping fee would be $10 for the first item and $5 for the other two items. The total shipping fee would be $20. Formula to calculate the total shipping fee: CURRENCY("$", 10 + (Order quantity - 1) * 5) Example #2: Let's say the shipping fee per item is $2 and you get a discounted shipping fee of $15 for a pack of 10 items. If a user orders 22 items, the shipping fee would $30 for 20 items plus and additional $4 for 2 individual items. Formula to calculate the total shipping fee: CURRENCY("$", Math.floor(Order quantity / 10) * 15 + (Order quantity % 10) * 2) Math.floor function returns the largest integer less than or equal to a given number. For example Math.floor(22/10) will return 2. We can use this function to find the number of 10 packs in the order quantity. The remainder operator % returns the integer left over after dividing one number by another. For example, 10 % 3 will return 1. 22 % 10 will return 2.
