Who this is for
Campaign math goes wrong when one-time and recurring costs get blended. Creative production, landing pages, and setup are paid once; media spend, tools, and management fees repeat every month. If you divide total revenue by total spend without separating the two, you cannot tell whether the campaign is improving or coasting on its launch.
Enter the launch cost as the initial investment, then add the monthly revenue you can credibly attribute to the campaign and the monthly cost of keeping it running. The calculator returns ROI, annualized ROI, net present value, and the month the campaign pays back its launch cost.
