Revenue forecasting is the foundation of business planning — it drives hiring decisions, inventory levels, marketing budgets, and cash flow management. Yet most small business owners either skip it entirely or do it on a back-of-napkin basis. The Utility Spark Revenue Forecast tool builds a structured 12-month revenue projection: enter your current monthly revenue baseline, monthly growth rate assumption, and any seasonal adjustment factors for specific months. For businesses with multiple revenue streams (product sales, services, recurring subscriptions), model each stream separately and aggregate. The output is a month-by-month revenue table and an annual total — a foundation for your P&L budget.

Why use our tool?
Growth Rate and Seasonality Modelling
Set a base monthly growth rate (compounding month-on-month) and apply seasonal multipliers to specific months. A retail business with a Diwali peak can model 3× revenue in October-November against the trend line.
Multiple Revenue Streams
Add separate streams (SaaS subscriptions, project revenue, product sales) with different growth rates and aggregate into a combined forecast.
Annual Summary and Visualisation
The 12-month table summarises total annual revenue and average monthly revenue, with a bar chart visualisation of the month-by-month profile.
How it works
Enter your starting monthly revenue (month 1 baseline).
Set your assumed monthly growth rate (% month-on-month).
Apply seasonal multipliers to specific months if applicable.
Add additional revenue streams if needed.
View the 12-month forecast table and annual total.
