eBay Auction Profit Calculator
Estimate your profit from an eBay sale after item cost, shipping, fees, and payment processing charges.
Overview
The eBay Auction Profit Calculator helps you estimate how much money you may keep from a sale after deducting your item cost, shipping expense, eBay fees, and payment processing charges. It is useful for checking whether a listing price is likely to leave enough profit before you post an item for sale.
How it works
The calculator adds the item price and shipping charged to find gross revenue. It then estimates marketplace and payment fees as percentages of that revenue, adds any flat transaction fee, and combines those charges with your item cost and shipping cost. Your estimated net profit is the amount left after subtracting all of those costs from the buyer's total payment. Profit margin shows that profit as a percentage of gross revenue.

Frequently asked questions
What does this eBay auction profit calculator estimate?
It estimates your net profit after subtracting item cost, shipping cost, eBay fees, payment processing charges, and any fixed transaction fee from the total amount paid by the buyer.
Should I include shipping charged to the buyer?
Yes. If the buyer pays shipping, include it as revenue because fees are often calculated on the full amount collected.
Do eBay fees apply to shipping too?
In many cases, selling fees are charged on the total order amount, which can include shipping. This calculator assumes your fee percentage applies to the total buyer payment.
Does this calculator include taxes or promoted listing fees?
No. It does not automatically include sales tax, VAT, ad fees, refunds, return costs, or packaging materials unless you account for them in your own cost inputs.
Can I use this for fixed-price listings too?
Yes. Even though it is called an auction profit calculator, the same profit logic works for many fixed-price eBay sales.
What is a good profit margin on eBay?
That depends on your product category, return rate, shipping risk, and time involved. This calculator helps you compare listings and decide whether the expected margin is worth it.
