Net = Sale Price - Buy Cost - Parts/Labor - Repack Box - Amazon Fees.

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.
Budget a mandatory 5% to 8% warranty reserve for Amazon Renewed products to cover mandatory 90-day replacement and customer refund guarantees.
Ensure all accessories (chargers, cables) meet OEM equivalent testing criteria to avoid condition complaints and account suspensions.

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: Refurbished Margin Tool

Sample inputs:

Renewed Resale Price ($): $189.00
As-Is Liquidation Buy Cost ($): $75.00
Testing & Parts Cost ($): $22.00
Renewed 90-Day Warranty Reserve ($): $9.00

Calculation:

Renewed resale price = $189.00, As-is buy cost = $75.00, Testing & parts cost = $22.00, Warranty reserve = $9.00
Amazon referral fee (15%) = 15% × $189.00 = $28.35
Amazon FBA fulfillment fee = $6.25
Total Amazon platform fees = $28.35 + $6.25 = $34.60
Total product & refurb outlay = $75.00 + $22.00 + $9.00 = $106.00
Net profit = $189.00 - $106.00 - $34.60 = $48.40
Net margin = ($48.40 ÷ $189.00) × 100 = 25.6%
Return on investment (ROI) = $48.40 ÷ ($75.00 + $22.00) × 100 = $48.40 ÷ $97.00 × 100 = 49.9%

Result: Net Profit: $48.40, Net Margin: 25.6%, ROI: 49.9%, Amazon Fees: $34.60, Note: Includes $6.25 FBA fee, 15% referral fee, and repack materials in parts cost.

Refurbishing liquidation units yields a strong 25.6% net margin ($48.40/unit) and 49.9% ROI after deducting parts, testing, warranty reserves, and Amazon fees.
