This is a currency-neutral order-contribution model, not a marketplace settlement or accounting profit statement. Fee bases, tax handling, refunds, and charges vary by channel and country.

Resell Profit Calculator example

The numbers are an illustration, not a current marketplace schedule. Replace the fee rate, fixed charge, revenue, and fee base with evidence from your channel.

Formula

The math behind the result

Order contribution = seller revenue − product cost − modeled platform fee − modeled payment fee − actual shipping − order-attributed advertising.

How it works

A clean flow from input to answer

  1. 1Enter the revenue that belongs to the seller, excluding marketplace-remitted tax.
  2. 2Enter the separate amount subject to percentage fees; use the marketplace or processor definition rather than assuming it equals item price.
  3. 3Copy platform, payment, and fixed fees from the relevant schedule or statement, then add actual product, shipping, and order-attributed advertising costs.
  4. 4Treat the output as contribution toward overhead, labor, returns, unsold inventory, and tax—not final business profit.

FAQ

Common questions

Why are seller revenue and fee base separate?

Shipping collected, handling, sales tax, and other amounts can be treated differently by a marketplace. The buyer total is not automatically seller revenue, and the fee base is not automatically item price.

Can I model free shipping?

Yes. Include the actual carrier, label, and packaging expense in shipping even when the customer sees a zero shipping charge.

Should I stack a marketplace fee and processor fee?

Only if both appear under the channel's current terms or actual statement. Some marketplace fee structures already cover payment handling.

How should advertising be entered?

Use the charge attributed to the order or a documented average from a consistent attribution method. Do not mix click cost with cost per completed order.

What remains outside the result?

Labor, storage, subscriptions, insurance, returns, damaged or unsold inventory, income tax, and any charge not entered remain outside the result.

The purchase-to-sale spread is only a starting point. This page separates three numbers that are often collapsed: what the seller earns from the order, what the provider uses to calculate percentage fees, and what fulfillment actually costs.

Reconcile a completed order

Start with a marketplace statement or payout detail. Record buyer total, marketplace-remitted tax, seller revenue, shipping collected, each fee line, advertising attribution, shipping-label expense, refund adjustments, and final payout. The calculator should reproduce the contribution only after those classifications are explicit.

If the estimate and payout differ, do not hide the difference in a generic rate. Identify whether it comes from tax, tiered fees, a fixed charge, conversion, advertising, a refund, or another account adjustment.

Separate order and business costs

Product acquisition, order packaging, shipping, and an order-level ad charge belong naturally in the order scenario. Monthly subscriptions, storage, insurance, labor, and owner compensation need a separate period model.

After finding average order contribution, multiply by a conservative order-volume scenario and subtract those fixed or period costs. That second step is required before describing the business as profitable.

Test the bad-order case

Build a separate returned-order scenario from your actual policy and provider statement: revenue reversed, fee credits or retained fees, outbound and return shipping, recovered inventory value, and damage. Do not apply a generic return percentage without evidence from the category or your own history.

A statement-first workflow

  1. 1Copy one completed order into the revenue and fee-base fields.
  2. 2Enter each current percentage and fixed fee only once.
  3. 3Add actual item and fulfillment costs.
  4. 4Reconcile the output to the statement, then create separate normal, returned, and discounted scenarios.
