What a Returned Order Really Costs
A returned order has two different financial effects: the amount paid back to the customer and the costs created by getting the product back into a saleable state. Keep them separate. The refund reverses the order’s revenue; it may include the product price, any refunded delivery charge and collected GST/HST. Tax collected on the sale is not product margin, so do not treat refunded tax as a second product cost.
The return-cost line should capture incremental costs caused by this order: outbound shipping that cannot be recovered, return postage paid by the store, non-refundable payment fees, return-authorisation and handling labour, inspection, cleaning, repackaging and relabelling. Add the product’s loss in value if packaging is opened, parts are missing, or the item can only be sold as clearance or used. A fully unsaleable item creates a write-down equal to its recorded inventory cost, adjusted for any recovery from liquidation or recycling.
Exclude costs that would exist without the return, such as general rent, ordinary software subscriptions and baseline warehouse salaries. Include labour only when the return creates additional work or measurable capacity usage. This separation lets you compare the cash refund, the operational return cost and the inventory loss instead of hiding all three inside a single return-rate percentage.
| Component | How to treat it |
|---|---|
| Customer refund | Reverse refunded revenue; separate product, delivery and tax amounts. |
| Shipping and payment | Include unrecovered outbound or return shipping and non-refundable processing fees. |
| Handling and recovery | Include incremental inspection, cleaning, repackaging and relabelling work. |
| Damage and inventory | Record the reduction from resale, clearance or unsaleable condition. |
| General overhead | Exclude costs that would occur without the return. |
How to Read the Worked Cost Example
Read the worked example from left to right, keeping each stage separate. It starts with order economics: the amount retained from a successfully delivered order after product cost, fulfilment, payment fees, advertising and other included costs. This is the contribution available before allowing for returns. Do not treat the customer’s tax payment as product revenue when the example excludes tax from revenue; use the same treatment throughout.
Next, follow the return-cost lines. The refund or reversed sales amount is shown separately from the costs of reverse shipping, inspection, repackaging, payment leakage, markdowns and any inventory value not recovered. Add only the costs included in the example to arrive at its net return cost. If a returned item is resold at full value, that recovery reduces the loss; if it is discounted or written off, the unrecovered amount remains a cost.
Finally, the allowable return rate compares the contribution from a kept order with the net cost created by a returned order. In the example, divide the former by the latter, using the displayed units and consistent tax treatment. That result is a break-even threshold, not a target: a rate above it would consume more contribution than the example allows, while a rate below it leaves contribution after return costs. Read the result alongside the assumptions, especially recovery value and whether advertising is included.
Worked example with sample numbers
This example is illustrative. It uses sample numbers for a kitchenware store selling in Canada. They are made up to show the method, they are not a benchmark, and your own figures will differ.
Formula: Cost per order sold = return rate x (delivery both ways + packing + value lost on resale).
| Return rate | Cost per order sold | Left over |
|---|---|---|
| 5.0% | C$2.21 | C$65.58 |
| 10.0% | C$4.42 | C$63.37 |
| 20.0% | C$8.85 | C$58.95 |
| 30.0% | C$13.27 | C$54.53 |

The Measures That Support Different Decisions
Each measure answers a different management question, so the useful comparison is about the decision it supports, not which metric is highest. Return rate shows how often products come back. If 8 of 100 shipped units are returned, the 8% rate is useful for spotting product, sizing, packaging or expectation problems and comparing collections with different order volumes.
Cost per returned order estimates the average financial burden each return creates. It supports budgeting and policy decisions: for example, $1,200 of return-related costs across 40 returned orders produces a $30 cost per returned order. Recovery value focuses on what remains economically recoverable after inspection, markdowns, damage or disposal. It is useful when deciding whether a product should be resold, discounted or treated as a loss.
Contribution margin after returns is the profitability test. It combines realized sales economics with return effects and advertising to show what remains from each product or collection. A high return rate may be tolerable for a strongly profitable item; a low rate may still be unacceptable if margins are thin. ORVX reports return rate by units and refund value against revenue, alongside product and collection profitability, so owners can choose the measure that matches the decision.
| Measure | Useful when deciding |
|---|---|
| Return rate | Where to investigate customer, product or fulfilment problems |
| Cost per returned order | How much return activity requires in operating budget |
| Recovery value | Whether returned stock should be resold, marked down or written off |
| Contribution margin after returns | Whether the product or collection remains commercially viable |
Local Consumer Rules to Confirm in Canada
Build a rule-check before changing a return policy. Start with the customer’s delivery province, product category, and transaction path: online sale, return, exchange, damaged item, or cancellation. Check federal guidance from the Competition Bureau and Canada Revenue Agency (CRA), then the relevant province or territory’s consumer-protection authority. Confirm requirements for disclosures, cancellation rights, defective goods, final-sale wording, refunds, and records; do not copy another province’s policy.
Use the CRA’s GST/HST guidance to confirm place-of-supply treatment, registration status, tax shown on refunds or credit notes, and whether shipping charges follow the same treatment. CRA states that goods shipped to another province are supplied where delivered, so that province’s rate applies. CRA also states that businesses generally remain small suppliers while taxable supplies do not exceed $30,000 over four consecutive calendar quarters.
Finally, check the carrier’s official terms for return labels, refused deliveries, damage claims, and cross-border parcels. Save each source, access date, screenshot, and policy version. Ask legal or tax advisers to review uncertain cases. ORVX can report refund value and return rate against revenue, but it does not determine compliance or file anything.
What a return really costs
A return cost should be assigned to the order, product and customer that created it. Separate the refunded selling amount from costs that remain after the item comes back: outbound shipping, return postage or label subsidy, payment fees that are not recovered, inspection and repacking labour, and any reduction in resale value. A $120 returned cookware set with $18 in unrecovered logistics and handling costs is not a $120 loss; the $120 is reversed revenue, while $18 is the incremental return cost. The margin you expected on the original sale is also gone.
Tax needs its own line. A tax-inclusive $100 order delivered in Ontario contains $11.50 of 13% HST, using the CRA rate and tax-inclusive calculation. That tax is not product revenue, but the refund and reporting treatment should match your records and applicable rules. For an interprovincial sale, CRA says the delivery province determines the GST/HST rate, for example, Ontario deliveries use 13% HST (Source: Canada Revenue Agency).
For action, compare return cost with contribution after advertising, not revenue alone. If a product generates $14 after product cost and advertising but each return consumes $18 in handling and logistics, a 10% return rate can erase its contribution even when its sales report looks healthy.
