MRR (Monthly Recurring Revenue)$25,000
ARR (Annual Recurring Revenue)$300,000
Churn rate3.0%
Runway12.0 months
Runway assumes today's burn rate stays constant - it will shift as revenue and spending change.

The formulas

MRR = Active customers x Average price per customer ARR = MRR x 12 Churn rate = Customers lost / Active customers x 100 Runway = Cash in the bank / Monthly cash burn
Example

500 customers at $50/month: MRR = $25,000, ARR = $300,000. Losing 15 customers = 3.0% churn. With $360,000 cash and $30,000/month burn: runway = 12 months.

Step-by-step guide

  1. Enter your active customer count and average price per customer per month.
  2. Enter customers lost this month to see your churn rate.
  3. Enter your monthly cash burn and current cash balance to see your runway.

Why these four numbers are the core SaaS dashboard

MRR and ARR describe the size and trajectory of the business - the recurring revenue base that predictable subscription models are built around. Churn rate describes how leaky that base is: even fast customer growth can be undermined by high churn, since losing a meaningful share of customers each month compounds against growth over time. Runway is the most urgent of the four for an early-stage or unprofitable company - it answers the practical question of how many months remain before the business needs new funding or profitability, assuming nothing changes.

Common mistakes

Confusing "average price" with your highest or most common plan - true average price should reflect your full customer mix across all pricing tiers.
Treating runway as fixed - it changes every month as revenue, new customers, and spending shift, so it's worth recalculating regularly rather than relying on a single snapshot.

Frequently asked questions

What's considered a "good" churn rate?

It varies significantly by market - many B2B SaaS companies target under 1-2% monthly churn, while some consumer subscription products tolerate higher rates. Context (contract length, price point, customer type) matters more than a single universal benchmark.

Does MRR include one-time payments?

No - MRR specifically captures recurring subscription revenue. One-time setup fees, professional services, or single purchases are typically tracked separately from MRR.

Should ARR just be MRR times 12, or is it more complex?

MRR x 12 is the standard, straightforward definition and what's used here - some companies make further adjustments for known upcoming contract changes, but the simple multiplication is the widely accepted baseline.
