Inputs used by this tool
The calculator displays the following fields. Your exact inputs depend on the selected tool and its available options.
- Monthly Units Sold
- Return Rate (%)
- Unsellable/Damaged Rate (%)
- Unit Landed Cost ($)
Calculation method and formula
The tool's registered calculation explanation is:
Loss = (Units Returned * Unsellable %) * Landed Cost + Units Returned * (Amazon 20% Referral Retained + Return Fee).
The result depends on the values you enter and the assumptions built into the tool. Where marketplace fees, carrier prices or tax rules apply, confirm the latest official figures before relying on the estimate.
Practical tips before you use the result
- Use current figures from your Seller Central reports, supplier quotation, invoice or other primary records.
- Keep the units consistent. Do not mix inches with centimetres, kilograms with pounds, or one currency with another.
- Test more than one realistic scenario when comparing prices, costs or campaign settings.
- Save or record the result you need before closing or refreshing the page.
- Include Amazon's return processing fee if you sell in the Apparel, Footwear, or Handbag categories where return rates frequently exceed 12%.
- Periodically submit FBA removal orders to inspect returned units rather than allowing Amazon warehouse staff to re-grade them as sellable.
Use the result as a planning estimate. Confirm current marketplace fee schedules, product dimensions, storage period and return assumptions before making a purchasing decision.
Worked example: Customer Return Loss Tool
Sample inputs:
- Monthly Units Sold: 500
- Return Rate (%): 4.5%
- Unsellable/Damaged Rate (%): 35%
- Unit Landed Cost ($): $12.00
Calculation:
- Monthly sales volume = 500 units, Customer return rate = 4.5%
- Estimated monthly customer returns = 500 × 4.5% = 22.5 units
- Unsellable damaged return rate = 35%; Unsellable units = 22.5 × 35% = 7.9 units
- Unsellable inventory loss = 7.875 units × $12.00 landed cost = $94.50
- Assumed per-return Amazon referral holdback / processing / restocking fee = 22.5 × $5.00 = $112.50
- Total estimated monthly return loss = $94.50 + $112.50 = $207.00
- Loss per sold unit = $207.00 ÷ 500 = $0.41
Result: Total Estimated Monthly Return Loss: $207.00, Loss Per Sold Unit: $0.41, Units Returned: 22.5, Unsellable Units: 7.9, Note: Assumes $5.00 per return Amazon referral holdback / processing / restocking cost.
A 4.5% customer return rate results in $207.00 in monthly return bleed ($0.41 per sold unit), driven by $94.50 in unsellable stock write-offs and $112.50 in Amazon return fees.
