eBay Profit Estimator

The eBay Profit Estimator calculates projected profit from an item sale after product cost, shipping, marketplace charges, advertising, and other seller-paid expenses. Every fee is entered as a user assumption so the estimate can match the listing category, account terms, shipping arrangement, and current fee schedule that apply to the sale.

Use the breakdown to identify which costs have the largest effect on profit and margin before listing or accepting an offer. The result is a planning estimate and excludes any tax obligations or overhead that you do not enter.

1. Enter selling revenue
Add the item price and any shipping amount paid by the buyer.

2. Add direct costs
Enter acquisition or production cost and the shipping amount you expect to pay.

3. Enter applicable marketplace charges
Use the percentage and fixed fees that match your category and seller terms.

4. Include promoted listing cost
Add the ad rate only when the sale is expected to incur that charge.

5. Review profit and margin
Check both the dollar result and the percentage of buyer payment retained as estimated profit.

Buyer payment = Sale price + Shipping income Marketplace fees = Buyer payment × Fee rate % + Fixed fees Advertising fees = Sale price × Promoted listing rate % Profit = Buyer payment − Item cost − Shipping cost − Marketplace fees − Advertising fees

The calculation uses the fee bases shown above. Adjust the entered rates or fixed-fee amount when your actual terms use a different base or include additional charges.

What the result means

The main result is the estimated amount left after all entered sale-level costs.

This estimate does not automatically include returns, income tax, storage, labor, or general overhead.

Given: Sale price is $120, buyer-paid shipping is $12, item cost is $55, shipping cost is $14, fee rate is 13.25%, fixed fees are $0.30, and ad rate is 2%.

Calculation: Buyer payment = $132. Marketplace fees = $132 × 0.1325 + $0.30 = $17.79. Ad fees = $120 × 0.02 = $2.40. Profit = $132 − $55 − $14 − $17.79 − $2.40 = $42.81.

Result: Estimated profit is $42.81, equal to about 32.43% of buyer payment.

Which fee rate should I enter?

Use the rate that applies to your category, account, and transaction. Fee schedules can change, so confirm the current amount in your seller information.

Should shipping income be included?

Yes when the buyer pays a separate shipping charge. The calculator also lets you enter the shipping expense independently.

How are promoted listing fees calculated here?

The estimator applies the entered ad rate to the item sale price. Change the assumption if your actual advertising charge uses another basis.

Why is profit different from cash received?

Cash received includes amounts needed to cover item cost, postage, and fees. Profit subtracts those entered costs from buyer payment.

Can I use this for an offer price?

Yes. Enter the proposed price and keep the remaining assumptions unchanged to see how the offer affects estimated profit.
