Knowing your fees is the start; the useful numbers are what to do about them. Break-even price is the lowest you can sell for without losing money. Price for target margin tells you what to charge to hit your goal. Max ad spend per order is your profit before ads — spend more than that and the order loses money — and break-even ROAS is the ad return you must beat to scale profitably. Default fees are typical published rates; confirm against your statements.
How it’s calculated
Fees = (price + shipping) × (platform % + payment %) + fixed fees. Net profit = price + shipping − fees − product − shipping cost − ad spend − return loss. Break-even and target-margin prices solve net = 0 and net = margin × price.

Worked example
A $30 Etsy sale costing $8 with $5 shipping and $2 ads nets about $10.31 (34% margin); break-even price is ~$18.61.
Common mistakes
- Forgetting payment-processing fees on top of the marketplace fee.
- Ignoring returns and ad spend, which quietly erase margin.
Where it is used
- Pricing a product to hit a target margin after all fees.
- Comparing the same item across Etsy, eBay, Amazon, and Shopify.
Frequently asked questions
How is break-even price calculated?
It solves for the sale price where profit is exactly zero, accounting for percentage fees, fixed fees, product, shipping, packaging, ad spend, and returns.
What does 'max ad spend per order' mean?
It's your profit before advertising. Spend up to that amount to acquire an order and you still break even; spend less and you profit.
Are the marketplace fees exact?
They're realistic defaults (Etsy, eBay, Amazon, Shopify). Tiers vary by category and plan, so override any field with your real numbers.
