How to use the Return Rate Calculator
Enter units sold and units returned for the same period or product.
Add the average selling price and, for profit figures, the unit cost.
Enter the cost of each return: return shipping you pay, handling, any restocking fee and the share of returns you can resell.
Press Calculate returns to see the return rate, refunds and total cost.
Use the table to see how much revenue and profit you would save by lowering the return rate.
Return rate and return cost formulas
Return rate = units returned ÷ units sold × 100
Refunds = units returned × price × (1 − restocking fee %)
Gross profit after returns = net revenue − cost of units not restocked − return shipping − processing
Example: 1,200 units sold at $45 and 96 returned is an 8% return rate. Refunds are 96 × $45 = $4,320, so net revenue is $54,000 − $4,320 = $49,680. Each return costs $6.50 shipping + $3.00 handling, and 20% of returns (at an $18 cost) cannot be resold: 96 × 9.50 + 19.2 × 18 = $1,257.60 in return costs.

Reading your result
Use the same basis: units with units, orders with orders, or revenue with revenue.
Allow for the return window: recent sales may still be returned, so measure periods that are old enough for returns to arrive.
Break it down by product, size or channel; one item with a very high rate can drive most of the cost.
Track return reasons (wrong size, damaged, not as described) to know which fix will pay off most.
Frequently asked questions
How do you calculate return rate?
Return rate = units returned ÷ units sold × 100. If you sold 1,200 units and 96 came back, the return rate is 96 ÷ 1,200 × 100 = 8%. You can also calculate it by orders or by revenue; just use the same basis for both numbers.
What is a normal return rate for online stores?
It varies widely by category. Apparel and footwear sold online tend to have much higher return rates than categories like groceries or consumables, because of sizing and fit. Compare your rate with your own history and similar products rather than a single benchmark.
What does a return really cost?
Beyond the refund itself, a return can cost return shipping, inspection and repackaging labor, and the value of items that cannot be resold. In the default example each return costs $9.50 in shipping and handling plus $3.60 on average in unsellable stock, before the $45 refund.
How does a restocking fee work?
A restocking fee is a share of the price you keep when an item is returned, often used for opened electronics or special orders. With a 15% fee on a $280 item, the customer gets $238 back and you keep $42. Check consumer law and marketplace rules before charging one.
Should I count exchanges as returns?
For a pure return rate, count every unit sent back. For the financial impact, an exchange usually costs shipping and handling but no lost sale, so you may track exchanges separately and enter only refunded units here.
How can I reduce my return rate?
Clear size charts, accurate photos and descriptions, customer reviews that mention fit, careful packing to prevent damage, and checking return reasons for patterns are the most common levers. Lowering returns by a few points can recover a large share of lost profit, as the table shows.
