Ecommerce Profit Calculator
Estimate net profit per order after product cost, shipping, platform fees, payment fees, ad spend, and expected returns.
Net profit per order
Formula
Gross Revenue = Product Price + Shipping Charged
Fees = Platform Fee + Payment Fee + Fixed Payment Fee
Net Profit = Gross Revenue - Product Cost - Shipping Cost - Fees - Ad Cost - Return Allowance
Net Margin = Net Profit / Gross Revenue * 100 How the formula works
The calculator treats product price and shipping charged as order revenue. It then subtracts the direct order costs you enter: product cost, shipping cost, platform fee, payment fee, fixed payment fee, ad cost, and return allowance.
Break-even ad spend is calculated by removing ad cost from the order model and asking how much room is left before profit reaches zero.
Complete example
An online store sells a product for $55 with free shipping. The product costs $18, shipping costs $6, platform fees are 6.5%, payment fees are 2.9% plus $0.30, ad cost is $8, and return allowance is 3% of revenue.
- Gross revenue: $55
- Platform fee: $55 * 6.5% = $3.58
- Payment fee: $55 * 2.9% + $0.30 = $1.90
- Return allowance: $55 * 3% = $1.65
- Total costs: $18 + $6 + $8 + $5.47 fees + $1.65 returns = $39.12
- Net profit: $55 - $39.12 = $15.88
- Net margin: $15.88 / $55 * 100 = 28.87%
The order is profitable under these assumptions, but the break-even ad spend is only $23.88. Spending more than that on ads would make the order unprofitable.

When to use this calculator
- Check whether a product is profitable after marketplace, payment, shipping, and ad costs.
- Compare Shopify, Etsy, Amazon, or other channel economics with different fee assumptions.
- Estimate how much ad spend one order can support.
- Review whether free shipping or discounts are reducing per-order profit too far.
How to interpret the results
Net profit is the estimated dollar profit per order after the costs entered. Net margin shows that profit as a percentage of gross revenue. Fee total helps you see how much platform and payment processing costs reduce each order.
Break-even ad spend is especially useful for paid acquisition. If your real cost per order is close to or above that number, the product may need a higher price, lower costs, better conversion rate, or lower return rate.
Common mistakes
- Checking product cost only and ignoring payment fees, marketplace fees, and fulfillment cost.
- Treating free shipping as free to the business instead of adding the actual shipping cost.
- Using average ad spend without accounting for returns or refunds.
- Comparing platforms without entering each platform fee structure separately.
- Leaving out fixed payment fees because they look small on one order.
- Using one return allowance for every product even when return rates differ by category.

FAQ
What costs should an ecommerce profit calculator include?
Include product cost, packaging, shipping or fulfillment, marketplace or platform fees, payment processing fees, ad cost per order, and a return or refund allowance.
Is ecommerce profit margin the same as gross margin?
Not always. Gross margin usually focuses on revenue minus cost of goods sold. Ecommerce net profit per order often includes selling fees, payment fees, shipping, ads, and expected returns.
What is break-even ad spend?
Break-even ad spend is the amount you can spend on ads for one order before profit reaches zero, based on the other costs entered.
Should shipping charged to the customer be included?
Yes. Shipping charged is revenue, while shipping cost is an expense. Enter both when the customer pays a shipping amount separately from the product price.
How should I estimate return allowance?
Use a realistic percentage of order revenue based on past returns, refunds, damage, chargebacks, or expected post-sale adjustments.
Can this calculator be used for Shopify, Etsy, or marketplace products?
Yes. Enter the fee percentages and fixed fees from your platform or marketplace. The calculator is independent and not affiliated with any platform.
Why is ecommerce profit lower than product margin?
Product margin often looks only at product cost. Ecommerce profit also includes fulfillment, platform fees, payment fees, ads, and return allowance.
Can break-even ad spend be negative?
Yes. A negative break-even ad spend means the order is already unprofitable before ads under the costs and fees entered.
