How to use the SEO ROI Calculator

  1. Enter your Monthly SEO cost and the Expected organic visits a month once SEO is working.
  2. Enter your Conversion rate, Average order value, Profit margin, the number of Months, and how many months traffic takes to grow.
  3. Press Calculate. The ROI appears with revenue, profit, cost, and the break-even month.

How it works

visits in month m = target visits × min(1, m ÷ ramp months)
revenue = visits × conversion rate × order value
profit = revenue × margin
ROI = (total profit − total SEO cost) ÷ total SEO cost

The break-even month is the first month in which cumulative profit is at least cumulative cost.

Examples

  • $3,000 a month, 10,000 visits after a 6-month ramp, 2% conversion, $80 orders, 40% margin, 12 months: revenue $152,000, profit $60,800, 68.9% ROI, break-even in month 5.
  • Over 24 months the same plan returns 91.1%, because full traffic runs for longer.

Why SEO ROI grows with time

SEO costs start on day one, but traffic builds over months. Once pages rank, visits often keep coming after the work slows, so the return over two or three years is usually much higher than in the first.

Limitations

  • Traffic, rankings, and conversion rates are estimates. SEO results are not guaranteed.
  • The value of brand awareness and returning customers is not counted.
