Retail Return Leakage Rate

It measures how much of your sales come back as refunds or store credit — dead weight on margin.

Formal definition

Return leakage rate equals the dollar value of returned merchandise divided by gross revenue, expressed as a percentage.

Why it matters

E-commerce and apparel often run 8–15% returns; above that, marketing spend effectively buys merchandise that boomerangs.

Where you see it

• Retail P&L reviews
• E-commerce platform analytics
• Loss prevention reports
• Buyer category planning
• Omni-channel KPI dashboards

Worked example

1. Gross sales: $400,000.
2. Return value: $24,000.
3. Return leakage = ($24,000 ÷ $400,000) × 100 = 6%.
4. Interpretation: 6¢ of every sales dollar returned — within many category norms.

How Business metrics calculates it

Return value ÷ Revenue × 100.

The range we use for status labels

On Business metrics, the status band for this KPI is roughly 0 to 8. Lower values are generally healthier in this band. Your niche can sit outside it honestly — the label is a prompt to read the coaching, not a certificate.

Where people fool themselves

Return rate including exchanges as full returns double-counts. Decide whether an exchange is a return plus a new sale, and stay consistent.
