How are the pricing components calculated in detail?

You can apply multiple discounts and surcharges simultaneously. They are always calculated in the order they appear in the configuration, from top to bottom.

Let's examine the calculation in detail using an example. Suppose we have a sea tour:

The customer makes a reservation:

• 2 adult tickets = 2 * 1000 = $2000
• 3 children's tickets = 3 * 600 = $1800
• 5 extra wetsuits = 5 * 100 = $500
• Brings their own camera

In this case, the pricing components are applied in the following order:

• 10% surcharge for bringing a camera
• 50% discount on wetsuits
• 40% holiday discount on the total cost

Before applying the discounts, the calculation table looks like this:

Element	Cost	Calculation
Adult ticket	2000	2000
Children's ticket	1800	1800
Wetsuit	500	500

For this pricing component, only price options are included in the calculation. This means the cost of the wetsuit is not considered when calculating the surcharge.

Calculation: 10% * (2000 + 1800) = $380.

The surcharge is distributed equally between the price options, $190 each.

Element	Cost	Calculation
Adult ticket	2000	2190
Children's ticket	1800	1990
Wetsuit	500	500
10% surcharge	380	-

For this pricing component, only the wetsuit is included in the calculation. This means the cost of the price options is not considered when calculating this discount.

Calculation: 50% * 500 = $250.

The discount applies only to the wetsuit.

Element	Cost	Calculation
Adult ticket	2000	2190
Children's ticket	1800	1990
Wetsuits	500	250
10% surcharge	380	-
50% discount	-250	-

Discounts and surcharges are calculated based on the Calculation field (not the initial cost). This discount applies to all price options and fields. It must be distributed evenly among all these elements.

40% * (2190 + 1990 + 250) = $1772.
= 590.67 + 590.67 + 590.67

Subtract $590.67 from each element.

Start subtracting from the smallest element.
Wetsuit: 250 - 590.67 = -$340.67.

In this case, the wetsuit price is completely offset, and there are remaining funds to be redistributed. Let's recalculate the discount, taking these remaining funds into account.
590.67 + 590.67 + 340.67 = $1522.
= 761 + 761

This discount should now be distributed between the two remaining items.
Children's ticket: 1990 - 761 = $1229.
Adult ticket: 2190 - 761 = $1429.

As a result, the invoice displays all the information from the second column. The calculation details are hidden.
