Plan pricing with clear fee breakdowns and insights. Adjust rates by category, promotions, and fee. Compare scenarios, export results, and decide confidently every time.
| Scenario | Gross sale | Category rate | Total fees | Net proceeds |
|---|---|---|---|---|
| Low price, no ads | $12.00 | 13.60% | $2.03 | $9.97 |
| Mid price, ads on item | $58.25 | 13.60% | $12.07 | $46.18 |
| International sale, higher fees | $149.99 | 15.30% | $27.91 | $122.08 |
gross = (item_price + shipping_charged + sales_tax_collected) − discounts_refunds
final_value_fee = gross × (category_rate ÷ 100)final_value_fee = min(final_value_fee, fee_cap_amount) (if enabled)
per_order_fee = 0.30 if gross ≤ 10, else 0.40 (auto) or a manual value.
international_fee = gross × (international_rate ÷ 100)promoted_fee = base × (promoted_rate ÷ 100)processing_fee = gross × (proc_rate ÷ 100) + proc_fixedtotal_fees = sum(all fees)
Most selling plans apply a percentage fee to the total amount of the sale, which typically includes item price, shipping, handling, and sales tax collected. That means a “free shipping” strategy does not remove fees; it mainly shifts where buyers see the cost. Use the same all-in pricing logic when testing two offers: (1) lower item price with higher shipping, versus (2) higher item price with lower shipping.
Category rates can vary substantially across product types. A small change in rate can move your net proceeds more than a small discount. For example, on a $120 gross sale, a 0.35% rate swing changes fees by $0.42. On high-volume products, that becomes meaningful. Keep a short list of your top categories and store the rate you actually see on invoices.
A flat per-order fee becomes a higher percentage as order value drops. If the per-order fee is $0.30 on a $9.99 order, that single line is about 3.0% before any percentage-based fee is applied. For small items, bundling multi-quantity listings can protect margin by spreading fixed fees across more revenue.
Advertising costs are optional, but they can be the difference between a fast sale and slow inventory. Start with a target ad cost-of-sale (ACOS), for example 4%–8%, and compare outcomes. If a 6% ad rate adds $3.60 to fees on a $60 item, your pricing needs room for that spend. Track conversion rate changes and only raise the rate when sales velocity improves.
Percentage add-ons often apply to the same gross base, so they stack. A 1.65% international fee on a $200 sale is $3.30. If you also model a 2.9% processing fee plus $0.30, that becomes $6.10 more. When you sell cross-border, consider higher item pricing or stricter minimum price floors.
Net proceeds show what you keep after fees; profit adds your cost of goods. Use margin thresholds to decide whether a listing is worth running. For example, set a minimum margin of 20% and a minimum profit of $8 per order. This makes pricing consistent across categories and reduces time lost on low-return listings.
