Formula and calculation questions

How is total cost calculated?
Total cost is item cost plus actual shipping cost plus other costs plus total fees.

Net profit equals gross received minus total costs.
How is profit margin calculated?
Profit margin is net profit divided by gross received, multiplied by 100.

Why might actual eBay fees be different from the estimate?

Inputs and results

What should I enter for item cost?
Enter what the item cost you to buy or make. If relevant, include only the direct cost of that item.
What belongs in other costs?
Other costs can include packaging, labels, inserts, advertising, handling supplies, or any extra direct sale expense.
Can profit be negative?
