About
Overview
Understanding your true profit margin is the most critical factor in running a successful e-commerce business. Many sellers make the mistake of assuming their profit is simply "Selling Price minus Product Cost." In reality, platform fees, shipping, taxes, ad spend, and returns can easily eat away at your bottom line. Our Profit Calculator helps you see the complete picture so you never accidentally sell at a loss.

Frequently Asked Questions (FAQ)
What is a "Break-even Price"?
The break-even price is the exact amount you need to sell a product for just to cover all costs (including fees and ads). If you sell below this price, you lose money. If you sell above it, you make a profit.
Why is ROI different from Margin?
Margin is the percentage of the selling price that is profit. ROI (Return on Investment) measures how much profit you make relative to the total cost of the product and marketing. ROI is often a better metric for evaluating ad campaigns.
What fees are included in the platform preset?
The presets use the standard referral commission for each platform (e.g., Amazon 15%, Etsy 6.5%). Note that fulfillment fees (like Amazon FBA) and fixed payment processing fees (like $0.30) should be added manually in the "Other Cost" field for the highest accuracy.
