Trade Profit Calculator

How to Use This Tool

Select your local currency from the dropdown to format all monetary results correctly. Enter your selling price per unit and total number of units sold for the trade transaction. Input all per-unit costs including product acquisition cost and shipping fees. Choose whether your marketplace charges a percentage-based fee on revenue or a fixed fee per unit, then enter the corresponding fee value. Add your local sales tax rate and any one-time fixed costs like marketing or packaging. Click "Calculate Profit" to see a detailed breakdown of revenue, expenses, and net profit. Use the "Reset" button to clear all fields and start a new calculation.

Formula and Logic

All calculations follow standard trade profit accounting practices:

• Total Revenue = Selling Price per Unit × Number of Units Sold
• Total Variable Costs = (Product Cost + Shipping Cost + Per-Unit Platform Fee + Per-Unit Tax) × Units Sold
• Total Platform Fees = (Revenue × Fee Percentage) OR (Fixed Fee per Unit × Units Sold) based on your selection
• Total Tax = Total Revenue × (Sales Tax Rate ÷ 100)
• Total Expenses = Total Variable Costs + Total Platform Fees + Additional Fixed Costs
• Net Profit = Total Revenue - Total Expenses
• Profit Margin = (Net Profit ÷ Total Revenue) × 100
• Break-Even Units = Additional Fixed Costs ÷ (Selling Price per Unit - Per-Unit Variable Costs)

Per-unit tax is calculated as Selling Price per Unit × (Tax Rate ÷ 100) to reflect sales tax applied to each unit sold.

Practical Notes

Trade businesses should aim for a minimum 15-20% net profit margin to cover unexpected expenses and reinvest in growth. Marketplace fees for e-commerce platforms like Amazon or Shopify typically range from 8-15% of revenue, so use the percentage fee option for these platforms. Fixed per-unit fees are common for payment processors like Stripe or PayPal, which charge a flat fee plus a small percentage. Always separate shipping costs from product costs to accurately track logistics expenses, which are often a major hidden cost for trade businesses. Break-even units help you determine how many sales you need to cover fixed costs before turning a profit. If your profit margin is below 10%, consider renegotiating supplier costs or adjusting your selling price to improve viability.

Frequently Asked Questions

What is a good profit margin for trade businesses?

Most small trade and e-commerce businesses target a 15-30% net profit margin. Margins below 10% are considered thin and leave little room for unexpected expenses, while margins above 30% are excellent for most consumer goods trades. Margins vary by industry: luxury goods often have 40%+ margins, while high-volume low-cost items may operate on 5-10% margins.

How do I account for variable platform fees?

Use the "Percentage of Total Revenue" fee type for marketplaces like Amazon, eBay, or Etsy that charge a percentage of each sale. Use the "Fixed per Unit" option for payment processors or logistics providers that charge a flat fee per item sold. If you have both types of fees, calculate the percentage fee first, then add the fixed fee to the additional fixed costs field.

Should I include shipping costs in product cost or separate?

Keep shipping costs separate from product acquisition costs to track logistics efficiency. Product costs refer to the amount you pay to source or manufacture the item, while shipping costs cover delivery to the customer. Separating these allows you to identify if high shipping fees are hurting your margins and negotiate better rates with carriers.

Additional Guidance

Regularly update your input values to reflect changes in supplier costs, shipping rates, or marketplace fee structures. Use the copy-to-clipboard feature to save calculation results for your accounting records or to share with business partners. Test multiple scenarios by adjusting the selling price and units sold to find the optimal pricing strategy for your target sales volume. If you sell across multiple marketplaces, run separate calculations for each platform to account for different fee structures. Always consult a professional accountant for official financial reporting, as this tool is for estimation purposes only.
