What the result means
The forecast is a planning estimate. The expected case uses your entered assumptions, while best and worst cases adjust the growth rate to show a practical range.
Expected revenue = Current revenue × (1 + growth rate - churn rate)^months.
Revenue forecasts are sensitive to churn, seasonality, pricing changes, and acquisition consistency.
Example calculation
A business with $50,000 monthly revenue, 8% growth, 2% churn, and a 12 month forecast reaches about $100,610 expected monthly revenue.
Tips for better results
- Use recent numbers rather than optimistic guesses.
- Run the calculator again after changing price, cost, or conversion assumptions.
- Treat the result as a planning estimate, not audited financial advice.
