Step-by-Step Calculation
Calculate gross revenue
Start by adding the item price and the shipping amount paid by the buyer.
grossRevenue = salePrice + shippingCharged
Calculate the percentage fee
Apply the entered fee rate to the total buyer payment.
percentageFee = grossRevenue * (finalValueFeeRate / 100)
Calculate total fees
Add the fixed order fee to the percentage-based fee.
totalFees = percentageFee + orderFee
Calculate net payout after fees
Subtract total fees from gross revenue to estimate how much remains after selling fees only.
netPayout = grossRevenue - totalFees
Calculate estimated profit
Subtract your item cost and actual shipping cost from the net payout.
profit = netPayout - itemCost - actualShippingCost
Calculate profit margin
Express profit as a percentage of the total amount paid by the buyer.
profitMargin = (profit / grossRevenue) * 100
Worked example for a typical sale
Gross revenue
50.00 + 8.00
$58.00
Percentage fee
58.00 × 0.1325
$7.69
Total fees
7.69 + 0.30
$7.99
Net payout after fees
58.00 - 7.99
$50.01
Estimated profit
50.01 - 20.00 - 6.00
$24.01
Profit margin
24.01 ÷ 58.00 × 100
41.4%
Final Result
Estimated total fees are $7.99, net payout after fees is $50.01, estimated profit is $24.01, and profit margin is 41.4%.
