| Sale Price | Qty | Item Cost | Discount | Shipping Charged | Shipping Cost | eBay Fee % | Payment % | Ad % | Other Cost | Overhead | Return % |

Formula Used
The calculator separates marketplace deductions from operating costs so you can see where your margin is being reduced.
- Effective Sale Price = Sale Price − Discount per Item
- Gross Revenue = (Effective Sale Price + Shipping Charged) × Quantity
- eBay Percent Fees = Gross Revenue × eBay Fee Rate
- Payment Fees = Gross Revenue × Payment Processing Rate
- Promoted Listing Fees = Effective Sale Price × Ad Rate × Quantity
- Return Reserve = Quantity × Return Rate × Return Loss % × (Item Cost + Shipping Cost + Packaging Cost + Other Cost)
- Total Costs = Platform Deductions + Cost of Goods + Shipping + Packaging + Other Costs + Overhead + Return Reserve
- Net Profit = Gross Revenue − Total Costs
- Net Margin = Net Profit ÷ Gross Revenue × 100
- Break-Even Sale Price solves the per-unit selling price required for profit to equal zero under your current fee and cost assumptions.

FAQs
1. What does this eBay profit calculator estimate?
It estimates gross revenue, marketplace deductions, operating costs, payout, profit per unit, net margin, ROI, and break-even sale price for your listing scenario.
2. Does the calculator include shipping income and shipping expense?
Yes. It adds shipping charged to buyer revenue and subtracts your actual shipping expense, helping you measure whether shipping supports or reduces margin.
3. Why is sales tax shown separately?
Sales tax is often collected and remitted by the marketplace. The calculator displays it for visibility but does not include it in profit unless you manually model it as a seller cost.
4. What is return reserve?
Return reserve is an expected loss estimate. It uses your return rate and loss recovery percentage to model how returns can reduce future profit.
5. How should I use overhead allocation?
Enter a flat amount you want this batch of sales to absorb, such as storage, subscriptions, labor, or utilities allocated to the orders being analyzed.
6. What does break-even sale price mean?
It is the minimum item sale price required to cover all included costs and fees, assuming your shipping charge, discount, return assumptions, and rates stay unchanged.
7. Can I use this for promoted listings?
Yes. Add your promoted listing rate and the calculator will subtract estimated ad fees from profit, helping you compare organic and advertised listing performance.
8. Why might my real payout differ slightly?
Actual payouts can differ because of category rules, tax handling, fee caps, refunds, adjustments, or timing differences. Use this tool as a planning model, not an official statement.
