ROAS Calculator – Calculate Your Return on Ad Spend
What is ROAS?
Return on Ad Spend (ROAS) shows how much revenue a marketing investment generated relative to the ad spend behind it. Unlike ROI, ROAS doesn't subtract further costs and shows the gross revenue effect rather than actual profit.

Example calculation
Revenue of $20,000 generated by advertising with ad spend of $5,000 gives a ROAS of 4 — every dollar spent generated $4 in revenue. Whether that is profitable depends on the profit margin of the product sold.
Why ROAS alone isn't enough
ROAS accounts for neither product costs nor other operating costs. A high ROAS can still be unprofitable if the profit margin is low, while a lower ROAS at high margin can still be quite profitable. In addition, the revenue credited to a channel is often distorted when several channels jointly contributed to a purchase.
Anyone who wants to view ROAS alongside profit margin, correct channel attribution, and actual ROI needs a model that accounts for these factors together.

How to increase ROAS
- Sharpen audience targeting toward users with higher purchase intent
- Increase average order value through cross-selling
- Shift budget toward campaigns with a demonstrably higher revenue contribution
- Adjust the attribution window to match the actual purchase decision process
Typical ROAS targets by business model
The following figures are rough guideline ranges and depend heavily on margin and business model.
| Business model | Typical ROAS target |
|---|---|
| E-commerce, low margin | 4–6 |
| E-commerce, high margin | 2–4 |
| Digital products / software | 1.5–3 |
ROAS vs. ROI vs. CPA
| Metric | Question it answers | Formula |
|---|---|---|
| ROAS | How much revenue per dollar spent? | Revenue / Ad spend |
| ROI | How much profit per dollar spent? | (Return − Cost) / Cost × 100 |
| CPA | What does a single conversion cost? | Ad spend / Number of conversions |
Frequently asked questions about ROAS
What counts as a good ROAS?
A ROAS of 4 is often cited as a solid benchmark in many industries, but it says little without knowing the profit margin. At low margin, even a ROAS of 4 can be unprofitable; at high margin, a lower ROAS can still be profitable.
What is the difference between ROAS and ROI?
ROAS compares revenue generated to ad spend without subtracting further costs. ROI subtracts total costs from the return and shows the actual profit.
Why can a high ROAS still be unprofitable?
Because ROAS ignores profit margin. At low margin, a large share of the revenue generated can be absorbed by product costs, leaving no profit in the end.
Should ROAS be calculated per campaign or per channel?
Both are useful. Campaign-level ROAS shows short-term optimization opportunities, while channel-level ROAS shows where a longer-term budget shift could pay off.
How does delayed purchase impact affect measured ROAS?
Too short a measurement window can understate ROAS if some purchases happen after the tracking period ends. For longer purchase decision processes, the window should be extended accordingly.
