What is ROAS?

ROAS (Return on Ad Spend) is a marketing metric used to measure the revenue generated for every dollar spent on advertising. It is crucial for businesses running paid campaigns on platforms like Google Ads, Facebook, or Amazon.
For example, if you spend $100 on an ad campaign and generate $500 in revenue, your ROAS is 5:1. This means you earned $5 for every $1 spent.
Break Even ROAS Calculator Formula
Break-Even ROAS is where your ad revenue equals your ad spend, meaning you’re neither making a profit nor a loss.
Understanding this is essential for scaling your campaigns.
Formula for Break-Even ROAS = Revenue per product / ( Revenue per product – Total costs per product)
Example:
If your profit margin is 25%, your break-even ROAS would be 4:1, meaning for every $1 spent, you need to make at least $4 in revenue to avoid losing money.

Why is Break-Even ROAS Important?

Knowing your break-even point helps you decide how much you can afford to spend on ads without impacting profitability. It’s a key indicator in campaign optimization, especially when scaling ad spend.
