Why MRR is the Holy Grail

Monthly Recurring Revenue (MRR) is the lifeblood of any subscription business. Unlike one-time sales, MRR compounds. If you add $1,000 in new MRR every month, by the end of the year, you aren't making $1,000—you're making $12,000/month.

The Silent Killer: Churn

Churn is the percentage of customers who cancel their subscription every month. It might seem small, but it compounds negatively against your growth.

Example: If you grow 10% month-over-month but have 10% churn, your business effectively stays flat. You are filling a leaky bucket. This simulator helps you visualize that ceiling.

Benchmarks for Success

  • Seed Stage: Focus on getting to $10k MRR. Churn will be high (5-10%) as you figure out product-market fit.
  • Growth Stage: Once you hit $50k MRR, your goal is to lower churn to < 3% and increase growth channels.
  • Scale: At $1M ARR ($83k MRR), net negative churn (upsells exceeding cancellations) becomes the goal.
