Frequently Asked Questions About E-Commerce Profit Margins
Is the E-Commerce Profit Margin Calculator free to use?
Yes. It is free, requires no login, and runs every calculation privately in your browser.
Does this calculator pull real fee invoices or sales data from my shop?
No. It computes net profit, margin percentage, markup, and break-even price solely from the product cost, shipping, selling price, and fee rates you enter.
What is the difference between profit margin and markup?
Profit margin is net profit divided by total order revenue. Markup is net profit divided by your direct product and shipping cost. For example, a $20 cost sold for $40 (with zero fees) has a 100% markup and a 50% margin.
Why are marketplace fees calculated on shipping charged to the buyer?
Marketplaces like Etsy, eBay, and Amazon apply transaction percentage fees to the total buyer payment, including shipping charges. Including shipping charged prevents unexpected fee shortfalls.
How is the break-even selling price calculated?
Break-even price is the lowest item price where total revenue covers your materials, packaging, shipping label cost, fixed order fees, and percentage commission with zero net loss.
