ROAS & Break-Even ROAS Calculator
Two numbers decide whether an ad campaign is making money or quietly losing it. Enter your results below — both update as you type.
1 — Your return on ad spend
2 — Your break-even point
Your costs are higher than your selling price, so no amount of ad efficiency can make this product profitable. Raise the price or cut costs before spending on ads.
The formulas
ROAS = Revenue ÷ Ad Spend × 100. Spend $500 to make $1,800 and your ROAS is 360%, also written as 3.6x. It tells you how hard each ad dollar worked — but on its own it says nothing about profit, because it ignores what the product costs you.
Break-even ROAS = Selling Price ÷ (Price − Product Cost − Shipping Cost) × 100. The term in brackets is your margin per order before ads. If a $49 product costs $14 to make and $6 to ship, you have $29 left for ads, so your break-even ROAS is 49 ÷ 29 ≈ 169%. Run below that number and you lose money on every order, however good the campaign looks in the ads manager.
Max CPA = Price − Product Cost − Shipping Cost. That same $29 is the most you can pay to acquire one customer without going under water. We use it as a hard ceiling when we set campaign targets: a CPA target picked from "what feels okay" is how stores end up scaling a loss.
Quick answers
What is a good ROAS? There is no universal number. A store with 80% margins profits at 150%; a store with thin margins loses money at 400%. Compare your ROAS against your own break-even figure, not against screenshots from other advertisers.
Should I include other costs? Yes, if they scale with orders — payment processing fees and packaging belong in the cost side. Add them to the product or shipping cost fields to keep the break-even honest.
