This calculator uses the core SEO ROI formula: (Revenue from SEO – Cost of SEO) / Cost of SEO × 100. Revenue from SEO is estimated by projecting future organic traffic, applying your conversion rate to get new customers, and multiplying by your average client value. It also calculates Customer Acquisition Cost (CAC) as Total SEO Investment / Customers acquired from organic search, and considers your Client Lifetime Value (LTV).

See your real numbersThis calculator uses standard industry formulas for SEO ROI: (Revenue from SEO – Cost of SEO) / Cost of SEO × 100. Customer Acquisition Cost (CAC) is derived from Total SEO Investment / Customers acquired from organic search.
The core formula for SEO ROI is (Revenue from SEO – Cost of SEO) / Cost of SEO × 100. This calculator uses your inputs for organic traffic, conversion rates, and client value to estimate the revenue generated by SEO. It then compares that revenue to your total SEO investment to give you a percentage return.
For sustainable growth and profitability, you should aim for a Customer Lifetime Value (LTV) to Customer Acquisition Cost (CAC) ratio of 3:1 or higher. This means that for every dollar you spend to acquire a customer through SEO, they should generate at least three dollars in lifetime revenue for your business.
SEO is a long-term strategy. While some initial improvements can be seen within a few months, significant ROI often takes 6-12 months to materialize. Most projection periods for SEO ROI calculators, including this one, consider a 12-24 month timeframe to account for the compounding nature of SEO efforts.
Smart businesses use both SEO and Google Ads together. SEO builds long-term, compounding authority and organic traffic that keeps delivering results. Google Ads provides immediate pipeline and captures demand right now. Combining them creates a powerful, integrated marketing engine that beats choosing one channel over the other.
Conversion rates vary widely by industry and website quality. However, for website visitors converting to leads or inquiries, a benchmark of 5-10% is typical for many local businesses and professional services. If your rate is lower, focus on improving your website's user experience and calls to action.
This calculator includes your 'Monthly SEO Investment' as a total cost. This investment should cover all aspects of your SEO strategy, including agency retainers, content creation, and any link building efforts. High-quality content typically costs $0.25-$1 per word, depending on its technical nature.
