Dropshipping Profit Calculator
Find out exactly how much profit you keep per dropshipping sale after paying your supplier, ad spend, and fees. Essential for validating product viability before scaling ad campaigns.
About this calculator
Dropshipping profit is calculated by subtracting every per-unit cost from the selling price. The formula is: Profit = sellingPrice − supplierCost − adSpend − otherFees. The supplier cost is what you pay the manufacturer or wholesaler for the item. Ad spend per sale is your total advertising cost divided by the number of sales it generated (i.e., revenue ÷ conversions). Other fees typically include payment processing (e.g., 2.9% + $0.30), platform fees on Shopify or WooCommerce, and return allowances. A positive result is gross profit per order; dividing it by the selling price gives your gross profit margin percentage. Dropshippers generally target margins of at least 20–30% after all costs, since thin margins leave little room to absorb refunds, chargebacks, or rising ad costs.
How to use
You sell a wireless charger for $39.99. Your AliExpress supplier charges $9.50. Your Facebook ads cost $120 to generate 8 sales, so ad spend per sale = $15.00. Payment processing and Shopify fees total $2.10. Enter Selling Price = $39.99, Supplier Cost = $9.50, Ad Spend = $15.00, Other Fees = $2.10. Profit = $39.99 − $9.50 − $15.00 − $2.10 = $13.39 per order. Profit margin = $13.39 / $39.99 = 33.5%, which is a healthy dropshipping margin worth scaling.
Frequently asked questions
What profit margin should I aim for in dropshipping to build a sustainable business?
Most experienced dropshippers recommend targeting a net profit margin of at least 20–30% per sale to stay viable. Margins below 15% leave you exposed to any cost increase — a rising cost-per-click, a supplier price hike, or a spike in returns can wipe out profitability overnight. High-ticket dropshipping (products over $200) can sustain lower percentage margins because the absolute dollar profit per order is still meaningful and ad spend scales more favorably.
How do I calculate ad spend per sale for my dropshipping store?
Divide your total advertising spend over a given period by the number of sales that ad spend generated. For example, if you spent $500 on Facebook ads and made 25 sales, your ad spend per sale is $500 / 25 = $20. This metric is also called Cost Per Purchase (CPP) in Facebook Ads Manager. It fluctuates daily, so use a rolling average over at least one week for a stable estimate to plug into your profit calculator.
What costs do dropshippers commonly forget to include when calculating profit?
The most frequently overlooked costs are payment processing fees (typically 2.9% + $0.30 per transaction), Shopify or platform subscription fees amortized per order, return and refund rates (even a 5% return rate meaningfully erodes margins), and currency conversion fees if your supplier charges in a foreign currency. Packaging inserts, shipping insurance, and customer service time are additional hidden costs. Adding an 'other fees' buffer of $1–3 per order is a prudent way to account for these variables.
