MRR = paying customers × average revenue per account (ARPA). Example: 120 customers at $49 ARPA gives $5,880 MRR. Defaults (100 × $50) show $5,000 Monthly, $60,000 Annual, and $50 ARPU side by side with 3 presets (Early, Growth, Enterprise).
Net new MRR = new + expansion − churned − contraction MRR. Example: $800 new + $200 expansion − $300 churned − $100 contraction = $600 net new MRR for the month. Positive net new means the business is growing.
Multiply by 12: $5,880 MRR × 12 = $70,560 ARR. This annualizes the run-rate; it assumes no churn or growth, so treat it as a snapshot, not a forecast.
Divide the annual contract value by 12 to get normalized monthly MRR. A $1,200 annual plan contributes $100 MRR. This keeps monthly and annual customers comparable.
