This blended approach prevents under-budgeting when customer acquisition needs exceed revenue-share assumptions, while still accounting for ongoing operational marketing costs.
It estimates a recommended marketing budget using projected revenue, target CAC, customer growth goals, fixed support costs, contingency, and planned channel allocation. It helps compare top-down and bottom-up planning methods in one model.
Revenue percentages give a strategic ceiling, while CAC planning reflects acquisition realities. Using the larger of the two helps avoid underfunding campaigns when growth targets demand more spend than a simple revenue ratio suggests.
Fixed costs include retention programs, software subscriptions, agency retainers, and creative production expenses. These are added to the acquisition budget because they support execution even when media buying levels change.
Contingency covers testing, price inflation, creative revisions, tracking fixes, or channel shifts. A small reserve improves budget resilience and prevents reactive cuts when campaign conditions change during the plan period.
The calculator automatically normalizes the values into proportional shares. That means you can enter relative weights instead of exact percentages, and the tool will still divide the final budget correctly.
Expected MER means projected revenue divided by the recommended marketing budget. It is a broad efficiency view that helps compare total revenue ambition against total planned marketing investment.
Yes. The calculator returns monthly and quarterly values from the final annualized budget. You can adapt the inputs for any planning horizon as long as revenue, customer goals, and costs follow the same timeframe.
No. It is a planning model, not a substitute for full finance forecasting. Use it with conversion rates, funnel assumptions, gross profit targets, and historical campaign performance for stronger decisions.
