How the break-even calculator works

Break-even ROAS is the return on ad spend where an order stops losing money. The calculator adds up everything one order costs you, product costs, payment fees, VAT, shipping, fulfillment and storage, and compares that total to your average order value.

VAT is treated as included in your gross price, the standard for EU ecommerce. If your AOV is 90 and your rate is 23%, the VAT share is 90 x 23 / 123, about 16.83, not 20.70. Getting this right keeps your break-even target honest instead of inflated.

Whatever is left after costs is your contribution margin. Divide AOV by that profit and you get your break-even ROAS, the floor every campaign has to clear. Your break-even CPA is the same profit number, the most you can pay for an order before it turns unprofitable.
