Calculation Method

Percentage Calculation Method

Determines how the percentage margin in the Margin % column is calculated.

Option	Formula	Description
Margin (Gross Margin) (default)	(Net Price − Purchase Price) / Net Price × 100	Profit as a percentage of the selling price
Markup	(Net Price − Purchase Price) / Purchase Price × 100	Profit as a percentage of the purchase price

Example: Purchase price €60, net price €100

• Gross Margin: (100 − 60) / 100 × 100 = 40%

• Markup: (100 − 60) / 60 × 100 = 66.7%

The plugin stores both methods pre-computed in the database. Switching the method takes effect immediately in the product listing — no re-index required.

Margin Thresholds

The thresholds control the color coding in the Margin % column.

Low Margin Threshold (%)

Default: 10

Margins below this value are shown in red. Red indicates that the margin is critically low or even negative (selling below purchase price).

Medium Margin Threshold (%)

Default: 30

• Margins between the low threshold and this value are shown in yellow.

• Margins at or above this value are shown in green.

Example with default values:

• Margin < 10% → Red

• 10% ≤ Margin < 30% → Yellow

• Margin ≥ 30% → Green
