How it works
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 + shippingCharged.
- 2Referral fee = Math.max(revenue × referralFeePercent/100, referralFeeMinimum).
- 3Fulfillment = productCost + actualShippingCost + packagingCost.
- 4Storage per order = avgMonthlyOrders >0 ? monthlyStorageOrWarehouse / avgMonthlyOrders : 0.
- 5Total costs = referralFee + fulfillment + closingFee + storagePerOrder.
- 6Net profit = revenue − totalCosts.
- 7Profit margin = netProfit / revenue ×100 when revenue >0.
Formulas
- Revenue = salePrice + shippingCharged
- ReferralFee = max(revenue×referral% , minimum)
- Fulfillment = product + actualShipping + packaging
- StoragePerOrder = monthlyStorage ÷ avgMonthlyOrders
- TotalCosts = referral + fulfillment + closing + storagePerOrder
- NetProfit = revenue − totalCosts
- Margin = netProfit ÷ revenue ×100
Important assumptions
- Revenue equals sale price plus shipping charged to buyer.
- Referral fee equals max(revenue × referralFeePercent, minimum).
- Fulfillment costs equal product cost plus actual shipping cost plus packaging cost.
- Storage per order equals monthly storage divided by average monthly orders when orders >0, else 0.
- Total costs equal referral fee plus fulfillment plus closing fee plus storage per order.
- Net profit equals revenue minus total costs and margin equals profit divided by revenue.
