Frequently Asked Questions
Everything you need to know about using this application.
How do I calculate net profit for my online shop?
To calculate net profit, you must subtract all associated costs—including listing fees, transaction fees, payment processing, shipping costs, and the cost of goods sold (COGS)—from your final item selling price.
Why is it critical to include payment processing fees in my pricing?
Payment processing fees are often a percentage of the total transaction plus a fixed fee per order. Ignoring these recurring costs is a common mistake that significantly erodes net profit margins over time.
What is the difference between profit margin and markup?
Profit margin is the percentage of the selling price that is pure profit. Markup is the percentage added to the original cost of a product to determine the final selling price. Understanding both is essential for sustainable business growth.
How does the breakeven calculator work?
The breakeven calculator determines the minimum price you must set to ensure your total revenue covers all fixed and variable costs, resulting in zero profit and zero loss.
