Frequently asked questions
How do I calculate Google Ads ROI?
Google Ads ROI is calculated as (Revenue - Ad Spend) / Ad Spend x 100%. For example, if you spend $5,000 and generate $20,000 in revenue, your ROI is 300% — meaning you earned $3 in profit for every $1 spent. This calculator shows the full funnel from budget to profit.
What is a good ROI for Google Ads?
A good ROI for Google Ads varies by industry, but generally 200% or higher (earning $2 for every $1 spent) is considered strong. Some industries with high customer lifetime values can accept lower initial ROI. Ecommerce businesses typically target 300-500% ROI on ad spend.
What conversion rate should I expect from Google Ads?
The average conversion rate for Google Ads Search campaigns is around 3-5%, though this varies significantly by industry. Legal and automotive tend to be higher (6-7%), while ecommerce is typically lower (2-3%). Your landing page quality and offer relevance heavily influence conversion rates.
