Step-by-Step Calculation
Calculate sales tax amount
Estimate the tax collected from the buyer using the item price plus shipping charged.
salesTaxAmount = (itemPrice + shippingCharged) * (salesTaxRate / 100)
Calculate the fee base
Combine the item price, shipping charged, and estimated tax to create the amount the percentage fee is applied to.
feeBase = itemPrice + shippingCharged + salesTaxAmount
Calculate the percentage-based fee
Apply the final value fee rate to the fee base.
percentageFee = feeBase * (finalValueFeeRate / 100)
Add the fixed fee
Add any flat per-order charge to the percentage fee.
totalEbayFee = percentageFee + fixedFee
Estimate proceeds before shipping cost
Subtract the total eBay fee from the pre-tax amount collected from the buyer.
netAfterFees = itemPrice + shippingCharged - totalEbayFee
Estimate net proceeds after shipping
Subtract your actual shipping cost to estimate what you keep after fees and shipping.
netProfitEstimate = netAfterFees - shippingCost
Worked example for a typical eBay sale
1. Sales tax amount
($50.00 + $8.00) × 0.08
$4.64
2. Fee base
$50.00 + $8.00 + $4.64
$62.64
3. Percentage-based fee
$62.64 × 0.1325
$8.30
4. Total eBay fee
$8.30 + $0.30
$8.60
5. Net after fees
$50.00 + $8.00 − $8.60
$49.40
6. Net proceeds after shipping
$49.40 − $6.00
$43.40
Final Result
Estimated eBay fee: $8.60. Estimated net proceeds after shipping: $43.40.
Assumptions
- ✓The percentage fee is estimated using one user-entered rate for the whole transaction.
- ✓The fee base is assumed to include item price, shipping charged, and estimated sales tax.
- ✓The fixed fee is treated as a single flat amount per order.
- ✓All amounts are entered in the same currency.
Limitations
- !Actual eBay fees may vary by category, account type, country, and transaction details.
- !The estimate does not include promoted listing charges, listing upgrades, refunds, disputes, or payment processing differences outside the given formula.
- !Rounding on live platforms may produce a small difference from the calculator result.
- !Tax handling can vary, so the tax portion of the fee base may not match every sale.
Common Mistakes to Avoid
Entering your actual shipping cost in place of shipping charged to the buyer.
Using a fee rate from the wrong category or seller account type.
Forgetting to set the sales tax rate to 0 when you do not want tax included in the estimate.
Mixing currencies between sale price, shipping, and fixed fee.
Comparing the estimate directly to a real payout that also includes refunds, ad fees, or other adjustments.
