[ What you get ]

What You Get

Every file below unlocks in your library the moment your order completes.

  • XLSXMarketing_ROI_Budget_Calculator.xlsxFive tabs: Inputs, Channel Budget, ROI and ROAS, CAC and Payback, Client Summary
  • PDFCalculator_Guide.pdfWhat every input means and how to read the results
  • TXTMONSTRO_Branding_Prompt.txtAI prompt for writing the client summary in your voice

Clients ask the same question in every budget conversation: what will we get back? The Marketing ROI & Budget Calculator answers it with the formulas already built. Enter the budget, channel split, cost per click, conversion rates and average order value, and the sheet calculates leads, customers, revenue, ROI, ROAS, CAC and payback period for each channel.

Five tabs, one story

Inputs holds the global assumptions. Channel Budget splits spend across up to eight channels. ROI and ROAS shows return by channel. CAC and Payback shows what a customer costs and how many months it takes to earn it back. Client Summary turns everything into a single page you can export. Input cells are colored, formula cells are locked against accidental edits and nothing needs macros.

Where it fits

Use it during budget planning, in proposals and in quarterly reviews. It works in Excel and Google Sheets. Pair it with the Client Strategy Presentation for the budget slides, or explore other agency spreadsheets. Free members also get the Agency Pricing Calculator.
