What problem does this calculator solve?
eBay sellers need a transparent way to incorporate selling fees, shipping, and purchase costs into their listing prices. Our calculator uses the terms you enter rather than an assumed platform fee schedule.
A marketplace payout is not automatically revenue or profit. This calculator separates net revenue, the fee base, and actual selling costs.
Six practical questions, answered clearly
Find the calculation behind your question. These answers explain how to use the inputs and results when making a decision.
How much will I keep after an eBay sale?
Enter sales revenue and all relevant fees and costs. The calculator shows the contribution that remains before unentered fixed costs and taxes.
How do I calculate eBay selling fees?
Enter the applicable percentage and any fixed fee. The calculator applies the percentage to the specified fee base.
How do I account for paid promoted listings?
Choose a fixed advertising cost or a percentage advertising fee. The calculator includes the selected method in costs and target-price calculations.
What selling price gives me €20 in contribution?
Enter purchase cost, shipping, fees, and a €20 target contribution. The calculator solves for the selling price needed under those assumptions.
When does offering free shipping make financial sense?
Compare charging for shipping separately with including shipping in the product price. Compare the remaining contribution using total buyer-paid net revenue in both scenarios.
How do customer returns change my eBay profit calculation?
Enter expected return costs per sale. The calculator shows their effect on average contribution. Use a net expected cost that does not double-count other expenses.
Worked example
Synthetic example: €100 net revenue, a 10% fee on €119, €50 other costs, and a 20% target margin yield €38.10 contribution. The rounded-up target price is €73.43.
Formula and calculation method
Calculate using your own assumptions
Enter values in a single currency. Results update as you change inputs. Save up to three scenarios for this session. Copy and CSV export include the assumptions and explanations used.
Practical use cases
- Separate charged shipping revenue from shipping cost.
- Test target margins when fee rates change.
- Include advertising costs in listing prices.
Assumptions and limitations
Enter terms for the market, category, account, and transaction. This is a single-percentage model without automatic tier, minimum, or listing fees. Allocate costs consistently per order or sale.

FAQ: Using the tool, capabilities, and calculation limits
Are eBay fees kept up to date automatically?
No. Enter fees from the current terms that apply to your account and sale.
Can I model personal and business sales?
Yes, as long as you enter the applicable fees and use a consistent cost and tax basis. The tool does not determine your seller or tax status.
Does the eBay calculation include shipping costs?
Yes. Actual shipping costs have their own field. Include shipping charged to the buyer in total sales revenue.
Can I include promoted-listing fees?
Yes. Both fixed advertising costs and percentage advertising fees are supported as alternative methods.
Can I calculate a minimum selling price?
Yes. The calculator derives the required price from costs, fees, and the contribution you want to retain.
Which fees should I include in my selling price?
Include the applicable percentage fee, fixed fees, shipping, purchase cost, and allocated ads. Do not reuse example assumptions in a real listing without checking them.
Does shipping charged to the buyer count as revenue?
Include it in total net revenue. Enter your actual shipping expense separately to expose any shipping surplus or subsidy.
Why is there a separate fee-base tax input?
A percentage fee charged on gross rather than net revenue needs the larger base. This input is neither a fee nor income tax.
Can this automatically model tiered fees?
No. The model uses a constant rate. You can enter a suitable effective rate for a price tier, but the same assumption must still hold at the target price.
Why can a target margin be impossible?
Fees plus target margin can consume all net revenue. No positive share remains for product and other costs, so simply raising the price cannot solve that model constraint.
