Understanding Return Rate
How we calculate. Return rate % = returned orders (or units) ÷ orders (or units sold) × 100. See our methodology and accuracy policy .
Real-world scenario: A typical Return Rate case uses returns 120 and orders / units sold 2000. Enter the same figures below to reproduce the worked path.
What is Return Rate?
A reverse-logistics and customer-experience KPI. E-commerce often tracks by units; B2B may track by orders—label the basis.
- Same basis for returns and denominator
- Define the return window
- Segment by reason for action
The Formula
Worked Example
Common Use Cases
- E-commerce ops: reverse volume
- Product quality: defect returns
- Network design: returns processing load
Pro Tips
- Separate refused vs customer returns
- Exclude exchanges if policy requires
- Watch category outliers
| Scenario | When to use |
|---|---|
| Percent of a number | Finding a part of a whole (tax, tip, score) |
| Percent change | Comparing old vs new values |
Limitations: Return Rate results are educational logistics and supply-chain planning aids—not SLAs, carrier contracts, or inventory valuation advice. Confirm definitions with your WMS/TMS and finance policies.
Common mistakes
- Swapping part and whole: The denominator must be the full total, not a subset.
- Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
- Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
