Return Financial Trajectory & Sensitivity
Stress-test profit erosion across return rate scenarios and holiday seasonality.
Hand-Verified Worked Example
• Gross Sales ($S) = $50,000
• Average Order Value (AOV) = $50
• Refund Rate (r) = 5.0%
• Payment Gateway Fee (f) = 2.9%
• Restocking Fee (k) = 10.0%
1. Total Orders = $50,000 / $50 = 1,000 orders
2. Refund Count = 1,000 × 5% = 50 refunds
3. Gross Refunded = 50 × $50 = $2,500
4. Double Fees = 2 × 2.9% × $2,500 = $145.00
5. Restocking Recovery = 10% × $2,500 = $250.00
Net True Loss = $2,500 + $145 - $250 = $2,395.00 (4.79% of sales)
