eBay Margin Estimator

The eBay Margin Estimator measures how much of a sale remains after product cost, marketplace charges, payment-related fees, shipping, packaging, advertising, and other order expenses. It reports profit per order and margin as a percentage of revenue, giving sellers a clearer view than sale price alone.

Use it when reviewing a listing, negotiating supplier costs, or testing whether a promoted-listing strategy still leaves enough room for profit. Because eBay charges can vary by category, seller status, country, and optional services, the calculator uses the rates and fixed amounts you enter rather than assuming one universal fee schedule.

1. Enter the buyer payment
Use the item price and any shipping amount collected from the buyer.

2. Add direct product cost
Enter what the item costs you before platform and fulfillment expenses.

3. Use your actual fee settings
Combine the applicable percentage charges and enter any fixed per-order fee separately.

4. Include fulfillment and promotion
Add actual postage, packaging, other order costs, and the advertising percentage when used.

5. Review profit and ratios
Compare profit per order, margin on revenue, and markup on product cost before setting the listing price.

Revenue = Sale price + Shipping charged
Percentage fees = Revenue × (Fee rate + Advertising rate) ÷ 100
Profit = Revenue − Product cost − Shipping cost − Other cost − Fixed fee − Percentage fees
Margin = Profit ÷ Revenue × 100

Where:

  • Revenue: total amount paid by the buyer, in dollars
  • Fee rate: combined percentage fee applied to revenue
  • Advertising rate: optional promoted-listing percentage
  • Profit: amount remaining after all entered costs

Assumptions: All percentage fees are modeled against total buyer payment. Actual fee bases, taxes, credits, and category-specific rules can differ.

What the result means

Positive margin means the entered sale covers all modeled costs; negative margin indicates an estimated loss.

This estimate does not automatically include taxes, refunds, reserves, currency conversion, or fee-rule exceptions.

Given:

  • Sale price: $75.00
  • Shipping charged: $6.00
  • Product cost: $28.00
  • Fee rate: 13.25%
  • Advertising rate: 2.00%
  • Fixed fee: $0.30
  • Shipping cost: $7.25
  • Other cost: $1.50

Calculation:
Revenue = 75 + 6 = $81.00. Percentage fees = 81 × 15.25% = $12.35. Profit = 81 − 28 − 7.25 − 1.50 − 0.30 − 12.35 = $31.60. Margin = 31.60 ÷ 81 × 100 = 39.01%.

Result:
$31.60 profit per order and a 39.01% margin.

Interpretation:
The listing retains about thirty-nine cents of profit for each dollar collected, before costs not entered here.

Should sales tax be included in the sale price?

Use the amount that your fee calculation is actually based on. If tax is collected and excluded from your fee base, leave it out; if your statement assesses fees on it, include it in revenue or model the difference as another cost.

What is the difference between margin and markup?

Margin divides profit by revenue. Markup divides profit by product cost, so the two percentages answer different pricing questions.

Can I enter zero for advertising?

Yes. Enter 0% when the listing is not promoted or when advertising is billed outside the transaction and you prefer to include it under other cost.

Why might my eBay statement show a different profit?

Real statements can include taxes, fee caps, category rates, international charges, refunds, credits, and subscription benefits. Use the calculator as an order-level estimate and reconcile it with your statement.

How can I use the result to set a minimum price?

Adjust the sale price until the displayed profit and margin meet your target. For a direct target-price calculation, use the eBay Price Estimator.
