Calculation example: make the margin tangible.
Assuming a gross retail price of €49,90, a purchase price of €16,00, packaging costs of €1,00, and shipping costs of €4,50.
Amazon
- Sales fee, usually 8 to 15 percent of the retail price per category.
- FBA, depending on size and weight.
- Ads, depending on the competition.
Example calculation. A 12 percent fee on €49,90 is €5,99. FBA: €4,30. Ads: €3,00 per order. Total variable costs: €13,29. Contribution margin before fixed costs: €49,90 minus €16,00 minus €1,00 minus €4,50 minus €13,29 equals €15,11.
Own shop
- Payment, approximately 1,5 to 3,0 percent plus a fixed component.
- Shipping 4,50. Packaging 1,00.
- Ads, initially higher, later decreasing through SEO and CRM.
Example calculation. Payment 1,50 percent and 0,35, equals 1,10. Ads 6,00 at the beginning. Contribution margin before fixed costs, 49,90 minus 16,00 minus 1,00 minus 4,50 minus 1,10 minus 6,00, equals 21,30.
These numbers are examples. Calculate with your exact values. Create a table for each SKU and then decide.
