FBA Return Rate Profit uses orders, return rate (%), average sale price.
Protecting contribution before accepting a price
For fba return rate profit, the relationship is Contribution after returns = orders × sale price × (1 − fee% ÷ 100) − orders × unit cost − orders × return% ÷ 100 × cost per return. The amount depends on the supplied orders, return rate (%), rather than a live market price or a value imported from another record. A quote can meet a revenue target and still leave too little to cover delivery. Separate the selling-price denominator from the cost denominator: margin and markup answer different questions. A discount changes contribution even when the supplier cost stays fixed.
What the model includes
Contribution after returns = orders × sale price × (1 − fee% ÷ 100) − orders × unit cost − orders × return% ÷ 100 × cost per return. A pricing review should retain the supplier cost, sale price and the reason for any allowance. Returns, payment charges, delivery and tax require explicit treatment; they should not disappear inside a percentage labelled profit. Compare the proposed price with the customer agreement and delivery capacity. A mathematically achievable margin does not establish that buyers will accept the offer.
Example with the supplied inputs
Orders: 1000; Return rate (%): 8; Average sale price: 40; Unit cost: 15; Marketplace fee (%): 15; Cost per returned order: 6. Result: 18,520. The values are illustrative.
Compare one changed input
Orders changes from 1000 to 1100. The result becomes 20,372. All other inputs remain fixed.
Calculation rule
Contribution after returns = orders × sale price × (1 − fee% ÷ 100) − orders × unit cost − orders × return% ÷ 100 × cost per return.
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Orders | 1000 | Use the source quantity represented by orders. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Return rate (%) | 8 | Enter return rate (%) on the percentage scale used in the formula (20 means 20%, not 0.20). Keep its base and reporting period consistent with the other inputs. |
| Average sale price | 40 | Use average sale price on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
| Unit cost | 15 | Use unit cost on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
| Marketplace fee (%) | 15 | Enter marketplace fee (%) on the percentage scale used in the formula (20 means 20%, not 0.20). Keep its base and reporting period consistent with the other inputs. |
| Cost per returned order | 6 | Use cost per returned order on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
Output: 18,520 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Orders, Return rate (%), Average sale price. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Orders on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 18,520.
Change Orders from 1000 to 1100 while keeping every other value fixed. The result becomes 20,372. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
