Dropshipping Profit Calculator
This calculator shows the real profit of one dropshipping order after supplier cost, shipping, fees, ad cost, refunds and returns — plus the break-even CPA and ROAS you must beat.
What is dropshipping profit?
Dropshipping margins look large until ad cost is added. Profit per order = selling price − supplier cost − shipping − fees − ad cost − expected refund and return losses.
How to use the dropshipping profit calculator (formula)
What each field means
- Selling price — Price the customer pays.
- Supplier cost — What the supplier charges you.
- Shipping cost — Shipping cost to the customer.
- Payment fee — Payment processor fee.

Worked example
Using these numbers: selling price $39.99, supplier cost $9.00, shipping cost $4.00, payment fee $1.50, platform fee $0.50, ad cost per order $14.00, refund rate 4%, return rate 2%, other cost $0.00.
The profit per order is $8.59.
- Break-even CPA: $24.99
- Break-even ROAS: 1.60x
- Profit margin: 21.5%
- Profit per 100 orders: $859.06
What is a good dropshipping profit margin?
After ad cost, 15–25% net margin per order is a solid dropshipping product. Below 10% is fragile because CPA moves daily.
Tips to improve your result
- Know your break-even CPA before launching ads.
- Price products at least 2.5–3× landed cost to leave room for ads.
- Include refunds — they are common with long delivery times.
- Kill ads that run above break-even CPA for three days.
