Revenue Forecasting Model — 36-Month Multi-Stream Excel Template

Description
Forecast up to three years of monthly revenue in minutes with this professional Excel model. BK004 lets you model multiple revenue streams independently — each with its own growth rate, churn, and annual price increase — while a shared monthly seasonality curve captures the natural ebb and flow of your business. No macros, no VBA, just transparent, auditable Excel formulas.


What This Model Does: Builds a rolling 36-month revenue forecast across up to 3 independent revenue streams. Applies monthly compounding growth, churn, and annual price increases per stream. Layers a 12-month seasonality curve on top of the underlying growth trend. Summarizes Year 1 / Year 2 / Year 3 revenue, total 3-year revenue, and CAGR. Visualizes the monthly revenue mix with a stacked bar chart by stream. Two-way sensitivity on total 3-year revenue across growth rate × churn rate, and growth rate × annual price increase. 9 automated validation checks catch bad inputs before you present the numbers.


Who It Is For: Finance teams and FP&A analysts building the revenue line of a budget or business plan, SaaS and subscription businesses forecasting MRR/ARR growth net of churn, startup founders preparing investor forecasts, sales and RevOps leaders planning against seasonality, and consultants building revenue models for clients.


What Is Included: The workbook contains 9 professionally formatted sheets: 00 Cover, 01 Instructions, 02 Assumptions, 03 Inputs, 04 Calculations, 05 Dashboard, 06 Sensitivity, 07 Checks, and 09 Version History. All calculations use native Excel formulas — no macros. Blue cells are inputs, black cells are protected formulas. Sheet protection password: BKFinance2026.
