Overview
Use this to estimate how often fulfilled orders turn into refunds. A high refund rate can point to product quality, unclear expectations, shipping damage, or traffic that never fit the offer.
Formula
Refunded orders ÷ fulfilled orders × 100.
Example calculation
Using the default example values from the JSON seed for this tool:
- Refunded orders
- 112
- Total fulfilled orders
- 4800
Result: 2.33% (Refund rate)
How to interpret this result
Refunded orders ÷ fulfilled orders for the rule set you adopt.
Partial refunds, fraud, and lag between order month versus refund month all deserve clear internal rules.
Signals product-market fit pains when paired with QA notes.
When to use this calculator
- When refunds cluster after fulfillment and you suspect quality or traffic mismatch
- Before you confuse partial refunds with full reversals unless rules say so
- When attribution by order month argues with refund-month reporting
- When Shopify or storefront exports finally align on fulfilled denominator
Rule of thumb
Order-date versus refund-date reporting changes the headline—stay consistent cohort to cohort.
