Separates one-time launch cost from recurring campaign spend so the payback period reflects how campaigns actually consume budget.
Enter your numbers first, then use the niche guidance below to interpret the output against marketing managers, agency account leads, and small business owners reviewing a campaign before renewing or scaling it..
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.
ROI is total net profit over the period divided by the initial investment, shown as a percentage. Net profit each month is attributed revenue minus recurring campaign cost, with an optional tax rate applied. Payback period is the initial investment divided by monthly net profit, and NPV discounts each month's profit back to today using the discount rate you set.
A services firm spends $20,000 building a campaign: creative, landing pages, and tracking setup. The campaign attributes $9,000 in new monthly revenue and costs $2,500 a month in media and management to keep running. The team models six months.
Monthly net profit is $6,500, so the launch cost pays back in just over three months and the six-month ROI is positive. The decision point is durability: if attributed revenue depends on a seasonal push, extending the model to twelve months with lower revenue assumptions is the safer test.
Interpretation assumptions: Amounts and percentage assumptions here are illustrative planning inputs, not measured industry averages. Compare results with your own costs and records; any displayed threshold bands are illustrative and do not establish typical business performance.
One-time costs: creative production, landing pages, tracking setup, list acquisition, and launch fees. Anything you pay again each month belongs in monthly costs instead.
Use the most conservative attribution you trust, such as tracked conversions times average order value, rather than total revenue growth during the campaign window.
Yes, at least roughly. If managing the campaign takes ten hours a month, price those hours; otherwise small campaigns look more profitable than they are.
Model paid search spend separately when search is the campaign's main channel.
Check the owned-audience channel that usually has very different cost structure.
Review whether overall margin supports more campaign spend at all.
Frames ROI around seasonality, lead cost, close rate, crew capacity, rework, safety, trucks, equipment, and material price volatility.
Connects ROI to patient volume, treatment mix, chair utilization, hygiene recall, insurance reimbursement timing, and equipment capacity.
