ROI = Net Profit/(Cost + Shipping Estimate)*100 for percentage
This change was made by users so they had a clearer picture of their actual ROI
But it appears this changed so now:
The profit calculations should be the following based on PD-3175:
For MFN and FBA:
StickerPrice = CostPerUnit field input value
DiscountAmount = StickerPrice*DiscountRate
SellerPaidSalesTaxEstimate = (CostPerUnit-DiscountAmount)*SalesTaxRate
FinalCostPerUnit = (StickerPrice-DiscountAmount)+SellerPaidSalesTaxEstimate
FBA:
Calculate the ROI given a List Price value:
Net Profit = List Price - (FinalCostPerUnit+AmazonReferralFee+FBA FulfillmentFees+ClosingFees+InboundShippingEstimatedFees+MonthlyStorageFees)
ROI = (Net Profit / FinalCostPerUnit) * 100
Calculate the List Price given an ROI value:
User puts in ROI% and we calculate the needed Net Profit from that using
NetProfit = ROI*FinalCostPerUnit
Use the Net Profit and fees to calculate the List price
List Price = 100(NetProfit+FinalCostPerUnit+FBAFulfillmentFees+ClosingFees+InboundShippingEstimatedFees+MonthlyStorageFees)/(100-100(CommissionPercent)
MFN:
AmazonReferralFee = ListPrice*CommissionRate
Calculate the ROI given a List Price value:
Net Profit = List Price - (FinalCostPerUnit+AmazonReferralFee+ClosingFees+EstMFNShipping)
ROI = (Net Profit / FinalCostPerUnit) * 100
Calculate the List Price given an ROI value:
User puts in ROI% and we calculate the needed Net Profit from that using
NetProfit = ROI*FinalCostPerUnit
Use the Net Profit and fees to calculate the List price
List Price = 100(NetProfit+FinalCostPerUnit+ClosingFees+EstMFNShipping)/(100-100(CommissionPerce
