A worked example
Input
2,000 prospects · 5% replies · 25% meetings · 20% closes $1,000 customer value · $1,500 costs
Output
5 expected customers · $5,000 modeled revenue $300 acquisition cost · 233.33% modeled ROI
Rates apply sequentially. The example is an editable scenario, not a benchmark or promised result.
What the result means
Keep customer value and campaign costs on the same time horizon. The table shows expected fractional outcomes, so compare scenarios rather than treating modeled customers as guaranteed sales.
Expected customers may be fractional. Customer value and costs must use the same time horizon. This is a scenario model, not a revenue forecast or guarantee.
Frequently asked questions
Should customer value be revenue, margin or lifetime value?
Choose a definition that matches the question you are modeling, and use a consistent time horizon for value and costs. For a contribution-based view, supply an appropriate contribution value rather than mixing lifetime revenue with one-month costs.
What happens with zero cost or zero customers?
ROI is undefined at zero cost, and cost per customer is undefined at zero expected customers. The tool labels these cases instead of displaying Infinity or implying a guaranteed break-even.
