Return on ad spend (ROAS) is the amount of revenue you earn for every dollar you spend on advertising. In plain terms, it tells you whether your paid ads are bringing in enough sales value to justify the spend. The standard formula is simple: revenue from ads divided by ad spend. If you spend $1,000 on Google Ads and those ads generate $4,000 in tracked revenue, your ROAS is 4.0, or 400%.
| Ad spend | Revenue from ads | ROAS | What it means |
|---|---|---|---|
| $500 | $1,000 | 2.0x | You made $2 for every $1 spent |
| $1,000 | $3,000 | 3.0x | You made $3 for every $1 spent |
| $2,000 | $10,000 | 5.0x | You made $5 for every $1 spent |
We like ROAS because it is easy to understand, but it only works well when your conversion tracking is clean. For eCommerce, that usually means actual purchase value. For local Orlando businesses like dentists, law firms, pest control companies, or roofers, ROAS can be harder because not every lead turns into revenue right away. In those cases, we often track booked calls, form leads, or qualified consultations first, then connect them back to closed revenue when possible. That gives you a more honest view of paid ads than judging campaigns by clicks alone.
A “good” ROAS depends on your margins, close rate, and overhead. A company with high margins may be happy at 3x ROAS, while a company with thin margins may need 5x or more. That is why ROAS is not the same as profit. If you sell a $200 service and spend $100 to get the sale, your ROAS is 2x, but after labor, software, and admin costs, your actual profit may still be weak. When we manage PPC campaigns, we treat ROAS as one score, not the whole story.
It also helps to know the difference between ROAS and ROI. ROAS looks only at ad spend versus revenue. ROI goes further and looks at profit after all costs. For businesses that rely on landing pages, call tracking, and lead forms, your site setup matters a lot, which is why conversion-focused web design can raise ROAS without raising budget.
If you are checking your ads and asking whether the number is healthy, start here: verify tracking, confirm the revenue tied to the campaign, compare ROAS by campaign and service, and judge it against your actual margins, not a generic benchmark. That will tell you whether your ads are really paying off.
