What is ROAS?
ROAS stands for Return on Ad Spend. It tells you how much revenue you generate for every dollar spent on ads:
ROAS = Revenue ÷ Ad Spend
A ROAS of 4x means every $1 of ad spend returns $4 in revenue.
What is a good ROAS?
The often-cited benchmark is 4:1, but the honest answer is "it depends on your margin." Your break-even ROAS = 1 ÷ profit margin. At a 25% margin you break even at 4x; below that you lose money. High-margin businesses (SaaS, info products) can profit at 2–3x, while thin-margin retail may need 6x+.
ROAS vs ROI
ROAS only compares revenue to ad spend. ROI accounts for your product/operating costs: ROI = (Profit − Spend) ÷ Spend. You can have a strong ROAS yet a negative ROI if margins are thin — which is why the calculator lets you enter a profit margin.

Frequently Asked Questions
- What is ROAS?
- ROAS (Return on Ad Spend) measures how much revenue you earn for every $1 spent on advertising. Formula: ROAS = Revenue ÷ Ad Spend. A ROAS of 4x means $4 of revenue per $1 spent.
- What is a good ROAS?
- A common rule of thumb is 4:1 (a 4x ROAS) for e-commerce, but the "good" number depends on your profit margin. With a 25% margin your break-even ROAS is 4x, so you need above 4x to profit. Low-margin businesses need a higher ROAS; high-margin businesses (like SaaS) can be profitable at 2–3x.
- What is the difference between ROAS and ROI?
- ROAS compares revenue to ad spend only (Revenue ÷ Spend), ignoring product and operating costs. ROI compares profit to spend ((Profit − Spend) ÷ Spend), so it reflects whether the campaign actually made money. You can have a high ROAS but negative ROI if margins are thin.
- How do I calculate break-even ROAS?
- Break-even ROAS = 1 ÷ gross profit margin. At a 50% margin, break-even ROAS is 2x; at a 20% margin it is 5x. Any ROAS above this point is profitable.
