Return Rate Cost Calculator
True cost of product returns.
Calculate the total cost of product returns from return rate, average order value, return processing cost, and restocking loss.
What this tool does
Total monthly return cost combines processing cost per return with restocking loss on returned items. The calculator estimates how many returns occur based on your monthly order volume and return rate percentage, then multiplies each return by its per-unit cost—including the refund amount, processing expenses, and restocking loss. The result shows the aggregate monthly financial impact of returns across your operations. Return rate percentage and average order value typically drive the largest swings in total cost. A common scenario involves an online retailer reviewing whether their current return processes are sustainable, or comparing how different restocking loss rates affect profitability. Note that this calculation assumes a stable return rate and does not account for variations in order timing, seasonal fluctuations, or secondary resale value of returned inventory. Results are for operational modelling purposes.
Quick answer: with the default values, the result is $50,500.00 (Monthly Return Cost). Adjust the values below for your own figures.

Product returns involve costs beyond the refund amount. Each return triggers: revenue refund, reverse logistics shipping, inspection and processing labour, restocking loss (damaged or unsaleable items), and customer service time. The total cost of a return can be multiples of the refund value once all costs are counted.
5,000 orders × 10% return rate = 500 returns. At 80 AOV: 40,000 refunded. Processing 5/return: 2,500. 20% restocking loss: 8,000. Total monthly return cost 50,500, or 101.00 per return. Annual: 606,000 — about 12.6% of annual gross revenue tied to returns.
Return rates vary by category; figures often cited include roughly 20-30% for apparel (sizing issues), 5-15% for electronics, 10-20% for home goods, and 2-5% for beauty, though these vary by market and product. Trimming the return rate by a couple of percentage points can move annual costs by a meaningful amount for a mid-sized store. Commonly discussed levers include clearer product photos, size guides with real measurements, reviews that mention fit, and virtual try-on.
Run it with sensible defaults
Using monthly orders of 5,000, return rate of 10%, avg order value of 80, return processing cost of 5, and restocking loss of 20%, the calculation works out to 50,500.00. The defaults are meant as a starting point.
The levers in this calculation
Among the inputs, Return Rate % and Avg Order Value move the result most, because Return Rate scales every cost component and Avg Order Value scales both the refund and the restocking loss. Return Processing Cost and Restocking Loss % have a smaller effect at typical values.
How the math works
Returns = orders × return rate. Cost = refund + processing + restocking loss. Total = returns × per-return cost.
With 5,000 monthly orders, a 10% return rate, £80 average order value, £5 processing per return, and 20% restocking loss, the monthly return cost is $50,500.00.
Inputs
| Revenue Refunded | $40,000.00 |
|---|---|
| Processing Cost | $2,500.00 |
| Restocking Loss | $8,000.00 |
| Returns per Month | 500 |
This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.
Sources & Methodology
Methodology
This calculator computes the monthly cost of product returns by multiplying the number of returned units by the cost per return. First, it calculates monthly returns by applying the return rate percentage to monthly orders. For each return, the calculator sums three cost components: the refunded order value, the fixed processing cost per return, and the restocking loss, calculated as a percentage of the order value. The refunded order value is counted in full as cost and restocking loss is added on top, with no credit for the cost of goods recovered or for items later resold, so the figure represents gross revenue at risk from returns rather than the net profit-and-loss impact. The model assumes a constant monthly order volume and return rate. It does not account for seasonal variation, changes in return patterns over time, variable processing costs, or the impact of returned inventory on future sales. Results represent a monthly figure and are an estimate rather than a precise projection.
