Use incremental visits, not your existing total.
The share of those visits that become orders.
Use sales after discounts and expected returns.
After product, fulfillment, payment, and other variable costs.
Include the fee and any other incremental SEO costs.

A scenario, not a forecast or measured ROI. The visit estimate assumes your entered conversion rate; actual orders are variable. No lifetime value or repeat purchases are included.
Calculate with margin, not just revenue
A $50 order does not leave $50 to pay for marketing. Product costs, fulfillment, payment fees, and other variable expenses come first. Enter the percentage left after those costs as your contribution margin. This calculator subtracts SEO spend from that contribution; it does not describe the result as total business profit.
Scenario ROI = (additional visits × conversion rate × order value × contribution margin − SEO cost) ÷ SEO cost × 100.
For example, 1,000 additional visits at a 2% purchase rate produce an expected 20 orders. At $50 per order and a 40% contribution margin, those orders contribute $400 before SEO. Subtracting a $299 fee leaves $101. This illustration does not predict that the plan will produce those visits or sales.
Use a consistent measurement period
Use monthly inputs together. Existing organic visits are not automatically incremental gains from new SEO work. To assess a real engagement, compare outcomes with an appropriate baseline, account for seasonality and other changes, and include your costs during onboarding and the months before any improvement. A single profitable month does not establish payback for the whole engagement.
What if margin or conversion is zero?
A positive SEO fee cannot be covered by orders with no contribution, or by visits that never convert. The calculator shows when break-even is not achievable with your inputs. ROI is undefined when the cost is zero. The tool excludes repeat purchases, customer lifetime value, fixed overhead, taxes, and the timing of cash flows.
