How do I create a sibling discount?

Sibling discounts are one of the most common types of discount. Here are the common settings and what you need to know:

Important: All discounts for products that offer instalments must use the "Discount (%)" field.

Sibling discounts use the person unit and are used to discount multiple siblings signing up for the same, or for different products.

Progressive Sibling Discounts

The most common sibling discount is to charge less money for each additional sibling.

In this example we set up a scaling discount that is progressively applied for each simultaneous  person attends, up to four siblings.

  • The first person pays £200
  • The second sibling pays £180
  • Each additional sibling pays £160
    • By leaving the "Range max" empty, we can have the discount continue to apply evenly to all siblings beyond the third

The additional siblings do not change the price of the sibling before them. This is explained in more detail here

You would set up this discount as below:


The price of the first sibling is the standard price set in the Product settings and does not need to be represented here.

Volume Sibling Discounts

Currently sibling discounts must apply the same discount to all involved siblings.

For example, if two or more siblings sign up, they each receive a 10% discount. For more details on how volume discounts work, view our full article here.

This would be set up as below:


The prices of the first sibling is the standard prices set in Product settings and does not need to be listed here. If a second sibling signs up, the 10% discount will apply to both siblings.

If you were to enter a figure in "Range max" it would stop the discount applying to additional siblings beyond that figure.

Applying the Discount to your Products

You would apply the discount to you products as normal. If your discount is only to apply to a single product, you can use the standard "Add discount" button to apply the discount to that class only. 

If the discount applies across multiple different products (for example, one child is in the Under 7s and another in the Under 10s), make sure to use the "Add multi-product discount" at the group level, and to have all relevant products in one group.
