About SaaS Revenue Projector

What is this tool?

The SaaS Revenue Projector is a dynamic calculator designed to model key metrics of a Software-as-a-Service (SaaS) business. By adjusting inputs like initial customers, monthly growth rate, churn, and average revenue per user (ARPU), you can generate instant projections for Monthly Recurring Revenue (MRR), Annual Recurring Revenue (ARR), and customer base growth over time.

Who is it for?

This tool is built for anyone involved in the SaaS ecosystem:

• Founders & Entrepreneurs: Quickly model different growth scenarios for business planning and fundraising.
• Finance & Ops Teams: Create financial forecasts and understand the impact of churn and growth on the bottom line.
• Investors & VCs: Evaluate the potential of a SaaS startup by stress-testing their growth assumptions.
• Students & Enthusiasts: Learn about the core mechanics of SaaS business models in an interactive way.

How it works

The projection is calculated month-by-month. For each month, we take the starting number of customers, add new customers based on the growth rate, and subtract customers lost due to churn. The resulting end-of-month customer count is then multiplied by the ARPU to determine the MRR, which is then annualized to get the ARR. This simple but powerful model provides a clear view of your company's potential growth trajectory.
