Methodology & formulas
This calculator is transparent by design. Review the steps and formulas so you can trust the estimate and adjust assumptions when your dashboard differs.
Calculation steps
- 1Revenue = salePrice × quantity.
- 2ReferralFee = max(revenue × referralFeePercent/100, referralFeeMinimum).
- 3ProductPrepTotal = (productCost + inboundShipping + packagingPrep) × quantity.
- 4FulfillmentTotal = fulfillmentCost × quantity.
- 5StorageTotal = monthlyStorage × quantity.
- 6PpcTotal = ppcPerOrder × quantity.
- 7TotalCosts = referral + productPrep + fulfillment + storage + ppc.
- 8GrossProfit = revenue − productPrep − fulfillment.
- 9GrossMargin% = grossProfit / revenue ×100.
- 10NetProfit = revenue − totalCosts.
- 11NetMargin% = netProfit / revenue ×100.
Formulas
- Revenue = salePrice × quantity
- Referral = max(revenue × referral%, minimum)
- ProductPrep = (product + inbound + packaging) × qty
- TotalCosts = referral + productPrep + fulfillment + storage + PPC
- GrossMargin% = (revenue − productPrep − fulfillment) ÷ revenue ×100
- NetMargin% = (revenue − totalCosts) ÷ revenue ×100
Important assumptions

- Referral fee per batch equals max(revenue × referralFeePercent, referralFeeMinimum) when revenue>0.
- Product and prep total equals (productCost + inboundShipping + packagingPrep) times quantity.
- Fulfillment total equals fulfillmentCost times quantity.
- Storage total equals monthlyStorage times quantity.
- PPC total equals ppcPerOrder times quantity.
- Total costs sums referral + product prep + fulfillment + storage + PPC.
- Gross profit equals revenue minus product prep and fulfillment only.
