Returns KPIs Every Fashion Store Should Track

The returns KPIs every fashion store should track are return rate, refund rate, exchange rate, return reasons, cost per return and resale recovery. Together they show how often items come back, why, and what each return costs you.

Each one has a simple formula, and you can calculate all of them from a spreadsheet. If fit is your main reason for returns, the AI size recommendation guide covers one way to prevent them.

What is the return rate?

Return rate tells you how many orders or items come back. Choose one definition and keep it fixed.

Formula: returned orders divided by total orders for the period, or returned items divided by items sold.

Use the same period for both numbers, and match returns to the month they were ordered. Otherwise a busy month will distort the next one.

What is the refund rate?

Refund rate is the share of orders or revenue you paid back. It differs from return rate, because some returns end in exchange or store credit.

Formula: refunded value divided by gross sales value for the period.

What is the exchange rate?

Exchange rate shows how many returns turned into another item instead of a refund. A higher exchange share means you kept the sale.

Formula: exchanges divided by total returns.

The guide to a size exchange flow on Shopify shows how to make exchanges easy.

Why do customers return items?

The reason mix is the most useful KPI, because it tells you what to fix. Record a reason for every return.

Typical reason codes include:

• Too small.
• Too large.
• Color not as expected.
• Quality problem.
• Arrived damaged.
• Changed mind.

Formula: returns with each reason divided by total returns. Track it by product too. The guides on return reason codes and analyzing return reasons by product show the method.

What is the cost per return?

Cost per return puts a price on the problem. Add up everything a return costs you.

Include:

• Return shipping you pay.
• Handling and inspection time.
• Packaging.
• Payment fees you do not recover.
• The markdown on items resold at a discount.

Formula: total return costs divided by the number of returns.

What is resale recovery?

Resale recovery measures how much of a returned item's value you get back. It shows whether returns go back to stock or become write-offs.

Formula: revenue from resold returned items divided by their original selling value.

A low number points to a grading or handling problem. The article on what to do with returned clothes you can't resell covers the other routes.

What does a worked example look like?

These numbers are made up to show the formulas. Use your own.

Input (illustrative)	Value
Orders in the month	200
Orders with a return	30
Refunds paid	24
Exchanges	6
Total cost of all returns	$360

Return rate is 30 divided by 200, so 15 percent. Exchange rate is 6 divided by 30, so one in five returns. Cost per return is $360 divided by 30, which is $12.

Which KPIs go together?

Read them in groups, not alone.

Question	KPIs to read together
How big is the problem?	Return rate, refund rate
Why is it happening?	Reason mix by product
What does it cost?	Cost per return, resale recovery
Are we keeping the sale?	Exchange rate

A rising return rate with falling exchange rate means customers are leaving with refunds. A high "too small" share on one product points to its size chart.

How do you set up tracking?

Start simple. A sheet with one row per return is enough for a small store. The simple spreadsheet returns tracker gives you a ready structure.

Add columns for order date, product, size, reason, outcome and cost. Update it weekly, and review the KPIs monthly.

How do you act on the numbers?

Pick one KPI to improve at a time. If "too small" leads, review the size chart and fit notes. If "color not as expected" leads, review photos.

The product page checklist for fashion stores lists the page elements that answer buyer questions before they order.

For disputes that go to your payment provider, read returns and chargebacks.

FAQs

How often should I review returns KPIs?

Monthly works for most stores, with a weekly check on the spreadsheet. Review sooner after a launch or a sale.

Should I measure return rate by orders or by items?

Either is fine if you stay consistent. Items give a clearer view when customers buy several sizes.

What is a good return rate?

It depends on your category and your own history. Compare against your past results first, not against another store.

Which KPI should a small store start with?

Start with the reason mix. It points to the specific fix, such as a size chart or photo.
