SEO ROI is the revenue your organic traffic generates divided by what you spend to earn it. The formula is simple: (SEO revenue minus SEO cost) divided by SEO cost, times 100. If you invest $1,500 a month and SEO drives $14,400 in monthly revenue, your ROI is 860%. The calculator above runs this math instantly from your own numbers.

How to use this SEO ROI calculator

  1. Monthly SEO investment. Your agency retainer or in-house cost. Most US small businesses pay $500 to $2,000 per month for SEO, with $1,000 to $1,500 the most common bracket according to industry pricing surveys.
  2. Extra monthly visitors. Be conservative: the added organic visits you expect after 6 to 12 months, not total traffic. When we ran SEO for Software Testing Stuff, a software-testing site, organic traffic grew by more than 10,000 visits a month, but plan on more modest gains for your projection.
  3. Conversion rates. Website visitor-to-lead rates typically run 2% to 5% for service businesses. Close rates of 15% to 30% are normal for warm inbound leads.
  4. Average customer value. Use first-year revenue per customer, or lifetime value if you retain customers for years.
  5. Equivalent CPC. What you would pay Google Ads for the same click. Legal and dental clicks often cost $10 to $50; most local services run $3 to $8.

What is a good SEO ROI?

Search Engine Journal's industry research puts average SEO ROI between 500% and 1,300% depending on the niche, against roughly 200% for paid search. SEO compounds: the content and authority you build keep producing traffic after you stop paying for clicks, which is why mature programs beat paid ads on ROI almost every time.

One caution: ROI math is only as honest as its inputs. If a calculator tells you what you want to hear, stress-test it with half the traffic and half the close rate. If the projection still beats your current marketing, SEO is worth the investment. For a projection built on your actual rankings and competitors rather than estimates, request a free SEO audit and we will model it for you with real data.

SEO ROI Calculator: questions, answered

How do you calculate ROI on SEO?
Divide your net return by your cost: (SEO revenue minus SEO cost) / SEO cost x 100. If you spend $1,500 a month and SEO-driven customers bring $9,000 in revenue, ROI is 500%. Use revenue from organic-source conversions in your analytics, not total revenue.
How long until SEO shows a positive ROI?
Most businesses cross break-even between months 4 and 9. SEO front-loads cost and back-loads return: rankings compound, so month 12 traffic is usually several times month 3 traffic at the same spend. Judge ROI over a 12-month window, not a 60-day one.
What is the average ROI of SEO?
Industry studies place average SEO ROI between 500% and 1,300% depending on the industry, versus roughly 200% for Google Ads. High-ticket niches like legal, dental and B2B SaaS sit at the top because each customer is worth thousands.
Is SEO worth it for a small business?
Usually yes, if customers search for what you sell and your average customer is worth more than about $100. Run your numbers in the calculator above; with a typical $750 to $1,500 monthly budget, even 20 to 30 extra leads a month produces strong returns for most local businesses.
Why does this calculator ask for an equivalent Google Ads CPC?
Because ad cost is the cleanest market price for a click. If your 2,000 monthly SEO visits would cost $8,000 in Google Ads and your SEO costs $1,500, organic search is delivering the same demand at about one fifth of the price, before counting compounding.
