About This Calculator

Projecting SaaS growth requires modeling the compound effect of monthly recurring revenue gains against churn losses over time. This calculator takes your current MRR, expected monthly growth rate, and churn rate to project your revenue trajectory over 12 and 24 months. It produces month-by-month forecasts so you can see when you will hit key milestones, plan hiring around projected revenue, and understand how small changes in growth or churn compound into dramatically different outcomes.

How to Use

  1. Enter your current MRR as the starting point for the projection.
  2. Input your expected monthly growth rate (new MRR added as a percentage) and your monthly churn rate.
  3. Review the month-by-month projection table and chart showing your MRR trajectory, cumulative revenue, and the net growth rate after accounting for churn.

Frequently Asked Questions

How does compound growth work in SaaS?

SaaS revenue compounds because each month's new MRR adds to the existing base, and the next month's growth applies to the larger base. At 10% monthly growth, $10K MRR becomes $31K in 12 months -- not $22K as simple arithmetic would suggest. This compounding effect is why even modest improvements in monthly growth rate produce outsized results over a year.

Why is net growth (growth minus churn) the number that matters?

Gross growth tells you how many new customers you are adding, but net growth determines whether your business is actually getting bigger. If you grow at 8% monthly but churn 6%, your net growth is only 2%. Two companies with identical gross growth can have vastly different trajectories depending on their retention, which is why churn reduction often delivers more value than increasing acquisition.

What growth rate do I need to double MRR in 12 months?

To double MRR in 12 months with zero churn, you need approximately 5.9% month-over-month growth. With 3% monthly churn, you would need roughly 9% monthly gross growth to achieve the same doubling. The higher your churn, the harder you have to push acquisition to maintain the same net trajectory.
