Most marketing reports stop at clicks, leads or ROAS. Those numbers can look healthy while the business still loses money on every new customer, because they ignore margin, other marketing costs and how often customers come back. This calculator joins them up in one place, using gross profit rather than revenue, so the answer reflects what the business actually keeps.
Enter what you spent on ads and on everything else that went into the campaign (agency or freelancer fees, tools, content), how many leads you got, how many became customers, the average order value, your gross margin, and how often and for how long a typical customer buys. The calculator shows cost per lead, CAC, LTV, the LTV to CAC ratio, ROAS, ROI on first orders and over the customer lifetime, and the CAC payback period.
The chart shows gross profit from one customer adding up with each order against the cost of winning them, so you can see when a customer starts to make money. The table underneath shows how lifetime ROI changes if your conversion rate or order value moves up or down by 15 to 30 percent, which is often the quickest way to see where improvement is worth most.
