Break even ROAS calculator
This break even ROAS calculator helps ecommerce operators and dropshippers find the exact ROAS required to break even, plus the maximum CPA they can afford, based on real costs.
Calculator
- Break-even CPA = net revenue (after VAT) minus non-ad costs (product, shipping, fees, other).
- Break-even ROAS = selling price divided by break-even CPA.
- The 10%, 20%, 30% targets assume you want that profit as a percentage of your selling price.
What you get (ROAS + CPA)
In paid acquisition, the hard part is not launching campaigns. It is knowing when campaigns are actually profitable.
This calculator gives you two numbers you can use immediately: your break-even ROAS and your break-even CPA. That means you can make data-driven decisions without guesswork, questionable tactics, or margin-killing mistakes.
How to use it
Add your selling price, VAT, product cost, shipping, and any per-order fees. These numbers define your true profit baseline.
Your break-even CPA is the maximum you can pay to acquire a customer. Your break-even ROAS is the minimum ROAS you need to avoid losing money.
How the math works
Most calculators only compare ad spend to revenue. That is rarely enough to reflect reality.
This break even ROAS calculator accounts for product cost, shipping, payment fees, and VAT. It then shows how your break-even point moves when you change variables such as AOV, shipping, or fees.
- If your actual ROAS is below break-even, you are losing money on each purchase (before LTV effects).
- If your actual ROAS is above break-even, you can decide whether to stabilize or scale based on the profit targets shown.
- If you want to reduce SaaS costs across your stack, you can compare with Ecom Efficiency pricing.
