Chain discounts are multiple discounts which a business offers on its original list price. They are useful in encouraging customers to take certain actions such as to making a volume purchase. This chain discount calculator is useful for calculating the net price of a product after deducting a series of discounts.


If you need further information on the use of chain discounts and the calculations they involve this is more fully discussed in our chain discounts in accounting tutorial.

The Excel chain discount calculator, available for download below, is used by entering details of the original list price and up to five discount percentages. The calculator works out the net price of the product after deducting the discounts and also calculates the single equivalent discount rate (SED) for the chain discount. To use the calculator enter the details as follows:

Step 1

Enter the original list price of the product.

Step 2

Enter up to five discount percentages. For example, if the business offers 25% trade discount on a particular product and then a further 10% for purchasing in bulk quantities (normally quoted as 25/10%), then enter 25% in column B and 10% in column C, and leave the other discount percentages blank or enter 0%.

For each percentage the calculator works out the discount given and the net price after that particular chain discount. The chain discount calculator also provides a summary showing the list price, total discount and net price to be paid.

Finally, the single equivalent discount rate (SED) is calculated. The SED represents the discount rate which when applied to the original price results in the same net price and total discount as applying the chain of discounts. For example, a chain of two discounts of 25/10% is equivalent to a single discount rate of 32.5%
