This tool calculates profit earned per individual transaction for small business owners, e-commerce sellers, and traders. It factors in revenue, direct costs, and transaction fees to show net profit per sale. Use it to evaluate pricing strategies and transaction efficiency.
Calculate net profit, margins, and fees for individual sales transactions
Transaction Details
Enter fixed $ amount or percentage (e.g., 2.9 for $2.90 fixed, 3.5 for 3.5% of revenue)
Optional: Shipping, packaging, handling fees per transaction
Enter to calculate total profit across multiple transactions
Profit Breakdown
How to Use This Tool
Enter your transaction revenue (total amount received from the sale) and direct cost of goods sold (COGS) for the transaction. Select whether your transaction fee is a fixed amount or percentage of revenue, then enter the fee value. Add any optional additional direct costs like shipping or packaging, and enter the number of transactions if you want to calculate total profit across multiple sales.

Formula and Logic
All calculations are based on standard profit per transaction formulas used in small business and e-commerce operations:
- Gross Profit per Transaction = Transaction Revenue - Cost of Goods Sold (COGS)
- Total Transaction Fees = Fixed Fee Amount OR (Transaction Revenue × (Fee Percentage / 100))
- Net Profit per Transaction = Gross Profit - Total Transaction Fees - Additional Direct Costs
- Profit Margin per Transaction = (Net Profit per Transaction / Transaction Revenue) × 100
- Total Net Profit (Multiple Transactions) = Net Profit per Transaction × Number of Transactions
Transaction status is determined by net profit: positive values are marked "Profitable", negative values "Loss", and zero "Break-Even".
Practical Notes
For accurate results, only include direct costs tied to the specific transaction. Do not include fixed overhead costs like rent, salaries, or software subscriptions, as these are not tied to individual transactions.
- Typical e-commerce profit margins range from 10% to 30% for most product categories, with higher margins common for digital goods or niche products.
- Payment processor fees (e.g., Stripe, PayPal) typically range from 2.9% + $0.30 to 3.5% + $0.15 per transaction for US-based sellers.
- COGS includes raw materials, manufacturing costs, and wholesale acquisition costs, but excludes marketing or shipping costs unless they are billed directly to the customer.
- Use this tool to test pricing scenarios: increase revenue by 5% or reduce COGS by 10% to see how it impacts per-transaction profit.
Why This Tool Is Useful
Small business owners and e-commerce sellers often focus on total monthly profit, but per-transaction profit is critical for evaluating pricing strategies and transaction efficiency. This tool helps you identify unprofitable transactions, negotiate better payment processor rates, and adjust COGS to meet margin targets.
It is especially useful for high-volume sellers processing hundreds of transactions monthly, where small per-transaction losses can add up to significant annual revenue drains.
Frequently Asked Questions
What is the difference between gross profit and net profit per transaction?
Gross profit only subtracts the cost of goods sold from revenue, while net profit subtracts all direct transaction costs including fees, shipping, and packaging. Net profit is the actual amount you earn from the transaction after all direct expenses.
Should I include overhead costs like rent in per-transaction profit calculations?
No, overhead costs are fixed expenses that do not change based on the number of transactions you process. Per-transaction profit should only include variable costs directly tied to the individual sale to give an accurate picture of transaction-level efficiency.
How do I improve my per-transaction profit margin?
You can increase revenue by raising prices, reduce COGS by negotiating better supplier rates, lower transaction fees by switching payment processors, or cut unnecessary direct costs like expedited shipping for standard orders. Test scenarios in this tool to see which adjustment has the largest impact.
Additional Guidance
Regularly audit your per-transaction profit across different product lines or sales channels to identify underperforming areas. For example, marketplace sales (e.g., Amazon, Etsy) often have higher fees than direct-to-consumer sales, which may require higher pricing to maintain margins.
Compare your per-transaction profit margins to industry benchmarks: retail averages 3-5% net margin, e-commerce averages 10-20%, and SaaS companies often exceed 30% for digital products. Use this tool to set realistic margin targets for your business.
