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
- 1Fee = $2.95 if sellingPrice <15 else sellingPrice × 20%
- 2Revenue = sellingPrice + shippingCharged
- 3CostsExFee = itemCost + actualShippingCost + packagingCost + otherCosts
- 4TotalOut = fee + costsExFee
- 5NetProfit = revenue − totalOut
- 6Margin = netProfit ÷ revenue ×100
- 7ROI = netProfit ÷ itemCost ×100 when itemCost>0
Formulas
- Fee = $2.95 (<$15) else 20% × price
- Revenue = price + shippingCharged
- Costs = item + actualShipping + packaging + other
- Profit = revenue − fee − costs
- Margin = profit ÷ revenue ×100
Important assumptions
- Poshmark fee $2.95 under $15 else 20% of selling price only, not shipping charged.
- Total revenue equals selling price plus shipping charged.
- Costs excluding fee equals item cost plus actual shipping cost plus packaging plus otherCosts
- Net profit equals revenue minus Poshmark fee minus costs excluding fee
- Does not include income tax or miles to post office — put those in otherCosts per order.
