eBay Discount Calculator
eBay sellers love running sales and sending offers to buyers, but discounts cut into margin twice because eBay fees still apply on the lower price while product and shipping costs stay fixed. Enter your regular price, discount type, and eBay fee rates to see regular versus discounted profit, margin erosion, and how many extra regular-price orders you need to make up the difference.

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
- 1Discounted price derived from discountType: percent_off and send_offer = regular × (1 − discount%/100), dollar_off = regular − discountValue.
- 2Revenue regular = regularPrice + shippingCharged, revenue discounted = discountedPrice + shippingCharged.
- 3Final value fee regular = revenueRegular × fvPercent + fvFixed, discounted = revenueDiscounted × fvPercent + fvFixed.
- 4Promoted fee = revenue × promotedPercent.
- 5Total fees = FVF + insertion + promoted.
- 6Fulfillment = productCost + shippingCost + packagingCost.
- 7Profit regular = revenueRegular − fulfillment − totalFeesRegular, discounted = revenueDiscounted − fulfillment − totalFeesDiscounted.
- 8Margin = profit / revenue × 100, margin change = discountedMargin − regularMargin.
- 9Total impact = (discountedProfit − regularProfit) × expectedUnits.
- 10Break-even extra = |totalImpact| / regularProfit when regularProfit >0.
Formulas
- Discounted = regular × (1 − %) or regular − $ depending on type
- Revenue = (salePrice + shippingCharged)
- FVF = revenue × fv% + fixed
- Total eBay fees = FVF + insertion + promoted
- Profit = revenue − fulfillment − totalFees
- Total impact = ΔProfit × expectedUnits
Important assumptions
- eBay revenue = (item price + shippingCharged) × quantity. Fees calculated per order base matches eBay's item plus shipping fee base.
- Final value fee = revenue × fvPercent + fvFixed.
- Promoted Listings fee = revenue × promotedPercent.
- Total eBay fees = final value + insertion + promoted.
- Discount applies to item price only, shippingCharged unchanged.
- Product, shipping actual, and packaging costs stay fixed regardless of discount.
- Break-even extra regular units = absolute total impact divided by regular profit per unit when regular profit positive.
Worked example
20 percent off eBay sale
$29.99 + $4.99 shipping regular, 20% off = $23.99 + $4.99, FVF 13.25% + $0.40, no insertion, no promoted, product $10, shipping $4.99, packaging $1.25, 50 units expected.
