This calculator helps you understand the financial impact of SEO before you invest. It takes three inputs (your current monthly traffic, conversion rate, and average order value) and applies projected growth percentages to show how improvements in search visibility translate directly to revenue. The formula is straightforward: more qualified traffic multiplied by a higher conversion rate multiplied by your order value equals more revenue. What surprises most businesses is how small percentage improvements compound; a 40% traffic increase combined with a 15% conversion rate improvement can more than double your monthly revenue.
Your current organic search visitors per month. Find this in Google Analytics under Acquisition > Search Console > Organic. If you do not have analytics set up, estimate based on your industry and current search visibility.
The percentage of visitors who complete a desired action (purchase, enquiry, or call). A typical website converts at 1-3%, but well-optimised pages can reach 5% or higher. SEO improves this by bringing higher-intent traffic.
The average revenue per conversion. For e-commerce, this is your average basket value. For service businesses, use the average value of a new customer over their first transaction or lifetime, depending on your model.
The calculator shows three figures: your current monthly revenue, your projected monthly revenue after the traffic and conversion improvements you selected, and the estimated annual impact. The monthly growth figure is the difference between current and projected; this is the additional revenue SEO could generate for your business each month. The annual impact multiplies this by 12 to show the cumulative yearly opportunity.
Remember that these are projections based on your inputs, not guarantees. Real-world results depend on your industry's search volume, the competitiveness of your target keywords, your website's current technical health, and the consistency of SEO work over time. Most businesses see meaningful results within 3 to 6 months of starting a structured SEO campaign.
If the projected revenue growth significantly exceeds the cost of SEO services, the investment has a clear positive ROI. Use the annual impact figure to compare against SEO pricing plans. If the annual return is 3 to 5x the annual cost, you have a strong business case. If your current traffic is very low, focus first on building search visibility through content and technical SEO. If your conversion rate is below 2%, improving landing page experience and targeting commercial-intent keywords should be your priority.
The calculator takes your current monthly traffic, conversion rate, and average order value, then applies projected increases in traffic and conversion rate to estimate your potential monthly and annual revenue growth from SEO investment.
The projected revenue figure represents the additional monthly revenue you could earn if your traffic and conversion rate increased by the percentages you selected. It is an estimate based on your inputs, not a guarantee. Actual results depend on your industry, competition, keyword quality, and the scope of SEO work implemented.
A 20-50% traffic increase within 6-12 months is realistic for most businesses starting with a moderate SEO foundation. New or poorly optimised sites may see higher percentage gains, while established sites with strong existing traffic may see smaller relative increases but larger absolute gains.
SEO does not just increase traffic; it brings higher-intent visitors who are more likely to convert. By targeting commercial keywords with clear buying intent, improving page speed, and optimising landing pages, you can increase your conversion rate alongside your traffic, compounding the revenue impact.
