Bundle Price Calculator

How it is calculated

You enter the sum of the prices the items would cost separately and the percentage discount for buying them together. The tool computes bundle price = total × (1 − discount ÷ 100) and savings = total − bundle price, in dollars rounded to cents. It also echoes the discount percentage. The discount is a percentage of the combined price, not of any single item, and it is a share of the price rather than of your profit. A discount of 0 gives the full price, 100 gives a free bundle, and a discount above 100 or a negative total returns nothing. The tool does not know your costs, so it cannot tell you whether the bundle price is still profitable.

Common mistakes

• Entering the discount as a decimal like 0.15 instead of 15. The field is a percentage, so 0.15 means a 0.15% discount and the price barely changes.
• Using the price of one item as the combined total. The first field must be the sum of every item in the bundle at its normal price.
• Adding the percentage to the margin. A 15% discount on the price can take much more than 15% off your profit per bundle, so check the result against your costs.
• Stacking another sale on top and expecting the two percentages to add. A second 10% off the bundle price is applied to $102.00, not to $120.00, so the total reduction is less than 25%.
• Rounding the displayed savings and bundle price separately in the product copy. Quote them as shown, because they are calculated from the same total and add up to it.
