How to Use This Tool
Start by selecting your base currency (the currency you use for accounting) and selling currency (the currency your customers pay in). If these differ, enter the current exchange rate for accurate conversions.
Fill in all per-unit cost fields: product cost from your supplier, international shipping fees, customs duties or fees for your target market, platform fees (e.g., Amazon’s 15% referral fee), payment processing fees (e.g., PayPal’s 3.4% + $0.30), and allocated marketing spend per unit.
Enter your selling price per unit and total units sold for the period you’re calculating. Click Calculate to see a detailed breakdown of per-unit and total profits, margins, and costs.
Use the Reset button to clear all fields and start a new calculation. You can copy your results to clipboard to share with your team or save for records.
Formula and Logic
All calculations are done in your selected base currency. If selling in a foreign currency, the tool first converts your selling price to base currency using the exchange rate you provide.
Per-unit calculations follow this logic:
- Per-Unit Platform Fee = Selling Price × (Platform Fee % ÷ 100)
- Per-Unit Payment Fee = Selling Price × (Payment Processing Fee % ÷ 100)
- Per-Unit Total Cost = Product Cost + Shipping + Customs Duties + Platform Fee + Payment Fee + Marketing Spend
- Per-Unit Net Profit = Selling Price - Per-Unit Total Cost
- Per-Unit Profit Margin = (Per-Unit Net Profit ÷ Selling Price) × 100
Total period calculations multiply per-unit values by total units sold.
Practical Notes
Cross-border e-commerce margins vary widely by category: general merchandise typically targets 20-40% net margins, while niche or luxury goods may target 50%+. Use local market benchmarks for your product category when evaluating results.
Customs duties and fees depend on your product’s HS code and the destination country’s trade policies. Check with a customs broker or official government portals for accurate per-unit estimates.
Platform fees often vary by product category: for example, Amazon’s referral fees range from 6% to 45% depending on the item type. Verify your platform’s current fee schedule before entering values.
Exchange rates fluctuate daily: use the rate valid on the date of the sale for the most accurate results, or use a monthly average for period-based calculations.
Why This Tool Is Useful
Many cross-border sellers overlook hidden costs like customs duties, payment processing fees, or allocated marketing spend, leading to inaccurate profit projections. This tool accounts for all common cross-border expenses in one place.
It helps you validate pricing strategies before launching in a new market: adjust your selling price to hit target margins, or identify cost areas where you can negotiate better rates with suppliers or logistics providers.
The detailed breakdown lets you see exactly which costs are eating into your margins, so you can make data-driven decisions to improve profitability for your international sales channels.
Frequently Asked Questions
What if my platform charges a fixed fee per transaction instead of a percentage?
Convert the fixed fee to a percentage of your average selling price, or add it to your per-unit marketing spend if it’s a flat monthly fee. For example, a $0.30 fixed PayPal fee on a $10 sale is 3% of the selling price.
How do I calculate marketing spend per unit?
Divide your total ad spend for a period by the number of units sold in that same period. For example, $500 in Facebook ads for 100 units sold equals $5 per unit in marketing costs.
Should I include returns or refunds in this calculation?
You can add average return-related costs (shipping, restocking fees) to your per-unit shipping or product cost fields. For example, if 5% of units are returned with a $2 restocking fee, add $0.10 to your per-unit cost ($2 × 0.05).
Additional Guidance
Always use conservative estimates for costs and exchange rates to avoid overestimating profits. It’s better to project lower margins and exceed them than to plan for high margins and fall short.
Compare your results to industry benchmarks for your product category and target market. If your margins are significantly below average, audit your supply chain, shipping providers, or platform fee structures for savings opportunities.
Recalculate profits regularly as exchange rates, platform fees, or supplier costs change. Quarterly reviews of your cross-border pricing and costs can help you maintain healthy margins as your business scales.
