How to calculate options and variants of the bundle?

To understand how to provide options for your customers, we've outlined the following logic to help you ensure that your bundle campaigns run smoothly while effectively managing pricing and inventory.

Sample

Consider the three products in the table below with their corresponding options and values. If a bundled product doesn't have a value for an option, it is marked with an (x).

Product name	Color	Size	Paper type	Cover material
Honey Bee Travel Notebook (P1)	Brown, Beige, Purple, Silver	A4, A5, B5	Dot, Grid, Lined	(x)
Soft Feather Travel Notebook (P2)	Purple	A4, A5, B5	(x)	Hardcover, Softcover
Moonflower Bullet Journal (P3)	Black, Beige, Pink	(x)	Dot	(x)

1. How bundled products are calculated?

All products added to the bundle are referred to as bundled products. Therefore:

Number of bundled products = Number of selected applicable products

From the sample, let's create two bundles to see how the calculations work.

Bundle 1: Select bundled products are P1 and P2 -> The number of bundled products is 2

Bundle 2: Select bundled products are P1, P2, and P3 -> The number of bundled products is 3

2. How options are calculated?

An option for the bundle is calculated when the options of the bundled product have more than one value selected (*). Therefore:

Number of options = Total number of calculated options from its bundled products

For Bundle 1:

• Select the following options and values for P1, and we determine that there are 3 option values that meet condition (*), meaning P1 has 3 options.

Option	Value	Calculated option	Explanation (compare to *)
Color	Brown, Beige	Yes	Has 2 values
Size	A4, A5, B5	Yes	Has 3 values
Paper type	Dot	Yes	Has 3 values

• Select the following options and values for P2, and we determine that there are 2 option values that meet condition (*), meaning P2 has 2 options.

Option	Value	Calculated option	Explanation (compare to *)
Color	Purple	No	Has 1 value
Size	A4, A5	Yes	Has 2 values
Cover material	Hardcover, Softcover	Yes	Has 2 values

Therefore, the number of options for Bundle 1 is calculated as:

Number of options = Calculated options of P1 + Calculated options of P2

Number of options = 2 + 3 = 5

For Bundle 2:

• Select the following options and values for P1 (similar to Bundle 1), and we determine that there are 3 option values that meet condition (*), meaning P1 has 3 options.

• Select the following options and values for P2 (similar to Bundle 1), and we determine that there are 2 option values that meet condition (*), meaning P2 has 2 options.

• Select the following options and values for P3, and we determine that there are 2 option values that meet condition (*), meaning P3 has 1 option.

Option	Value	Calculated option	Explanation (compare to *)
Color	Black, Beige, Pink	Yes	Has 3 values
Paper type	Dot	No	Has 1 value

Therefore, the number of options for Bundle 2 is calculated as:

Number of options = Calculated options of P1 + Calculated options of P2 + Calculated options of P3

Number of options = 2 + 3 + 1 = 6

3. How variants are calculated?

The number of values for each option is referred to as option values.

Variants of the bundle are calculated based on these option values for each bundled product. They are computed by:

Number of variants = Product of variants for each bundled product

From the selected sample, we get:

• P1 has 2 x 3 x 3 = 12 variants

• P2 has 1 x 2 x 2 = 4 variants

• P3 has 3 x 1 = 3 variants

Therefore:

The number of variants for Bundle 1 is:

Number of variants = Variants of P1 × Variants of P2

Number of variants = 12 × 4 = 48

The number of variants for Bundle 2 is:

Number of variants = Variants of P1 × Variants of P2 × Variants of P3

Number of variants = 12 × 4 × 3 = 144

Finally, once you’ve mastered the calculations, you’re ready to create bundles that meet all the requirements. Let’s dive back in and set up bundles that work perfectly for your needs!
