How the SEO ROI calculator works

The calculator multiplies the extra monthly organic visits you expect by your website conversion rate to estimate new leads, then by your lead-to-customer rate and average customer value to estimate revenue. It compares that revenue with your monthly SEO investment to show return on investment and the number of months of revenue it would take to pay back a year of SEO.

Results are estimates, not promises. The biggest uncertainty is the traffic figure: use a conservative number based on the search volume for your target keywords and a realistic share of clicks. We can help you work that out during a free SEO audit.

Choosing realistic inputs

  • Extra monthly visits: start with the monthly search volume for your main keywords and assume you capture a modest share, not all of it.
  • Conversion rate: use your current website conversion rate from analytics. Many service sites see low single-digit percentages.
  • Close rate: the share of leads that become paying customers, from your CRM or sales records.
  • Customer value: use gross profit or lifetime value per customer if you know it, rather than first-order revenue.
  • Monthly SEO cost: your agency fee or the cost of internal time.

SEO returns build over time, so a single month rarely tells the full story. Look at the 12-month figures, and remember that rankings built today can keep producing leads long after the work that earned them. Compare plan costs on our SEO pricing page.

FAQs

Frequently asked questions

Need something more specific? Ask a strategist

01How do you calculate SEO ROI?

SEO ROI is the revenue or profit generated by organic search, minus the cost of SEO, divided by the cost of SEO. This calculator estimates revenue from extra visits, conversion rate, close rate and customer value.

02What is a good ROI for SEO?

It depends on your margins and sales cycle. Because SEO results compound and continue after the work is done, the return over two or three years is usually more meaningful than the first few months.

03How long does it take for SEO to pay for itself?

For many businesses, SEO takes six to twelve months to break even, depending on competition, starting authority and customer value.

04Is this calculator accurate?

It is only as accurate as the inputs. Use conservative traffic estimates and your real conversion data for the most useful result.

05Do I need to give my email to use the calculator?

No. The calculator works without any signup. You can optionally email yourself a copy of the results.
