What a Return Really Costs: The Full Calculation

The parts of a return

• Courier out and back. The charge for delivering the parcel, and for returning it, which is often billed separately.
• Handling. Receiving, inspecting and restocking the parcel takes someone’s time.
• Goods you cannot resell. If the item returns damaged, opened or too late to sell, its cost is a loss.
• Fees that are not refunded. Some payment processors keep their fee when you refund a sale.
• The margin you never earned, which is the opportunity cost rather than an expense, but belongs in any honest view of the order.
• The ad spend that produced the order, which is spent whether the order stays or not.

The formula

cost of return = courier charge out               + courier charge back               + handling               + payment fees not refunded               + cost of goods lost (if not resellable)

Count the cost of the goods only when they cannot be sold again. If they go back into stock their cost is not lost, and counting it would write the same stock off twice.

Two returns compared

Refused cash-on-delivery parcels

With cash on delivery a buyer can refuse the parcel at the door at no cost to them. The courier trip both ways is yours to pay, and the sale never happened. This is often called RTO, return to origin. The share of orders that end this way is one of the most important numbers a COD seller can track, by product, by courier and by campaign.

Ways to bring it down

• Confirm orders by phone or message before shipping, where the order value justifies it.
• Check the customer’s history, ideally by phone number, which identifies a person far better than a name.
• Describe products accurately, so what arrives is what was expected.
• Compare couriers on return rate as well as price.
• Watch the campaign: some ads bring orders that come back far more often than others.

How the books should treat it

A returned order’s revenue should not count. The courier charge for the trip stays as a cost, shown on its own so you can see what returns are costing you. Goods back in stock are credited at cost; lost goods are not. A return with no courier charge yet should be shown as unpriced, not filled in with a guess. This is how ProfitIQ treats it: see returns and RTO costs.
