How to Use the Calculator

STEP 1

 

Enter Your Current Numbers

 

Begin with your actual business data. Enter your current monthly organic traffic, conversion rate, lead-to-sale close rate, average order or job value, customer lifetime value, projected organic growth, and your expected monthly SEO investment. Use the sliders to adjust assumptions quickly or type exact figures for precision. The results update instantly as you change each field.

 

Step 2

 

Set a Realistic Growth Assumption

 

Projected organic growth is the main forecasting lever in the model. It applies only to your current monthly organic traffic. The calculator does not assume additional market share, impressions, or inflated demand. It models growth from your existing baseline. You can test different growth scenarios to see how changes in traffic impact revenue and ROI.

 

Step 3

 

Review Your Commercial Forecast

 

Once your inputs are entered, the calculator immediately estimates additional traffic, leads, new customers, first-sale revenue, lifetime value upside, break-even customers, monthly ROI, and annual net return. There is no separate calculate button. The forecast adjusts live as you refine your assumptions.

 

How to Interpret Your Results

If your monthly ROI is positive, projected first-sale revenue exceeds your monthly SEO investment. Based on your inputs, the additional customers would cover the cost of the campaign. This reflects commercial viability under your assumptions, not a guarantee.


If your monthly ROI is negative, projected first-sale revenue does not cover the investment at your current settings. This may indicate conservative growth, low conversion rate, or a weak close rate. Adjusting these variables will change the outcome.


The break-even figure shows how many additional customers are required each month to cover the investment based on first-sale value. It reframes the decision in customer terms rather than cost alone.


Lifetime value revenue is shown separately as long-term upside. It is not included in the ROI calculation. ROI is based on first-sale revenue only to keep the model conservative and time-aligned.
