Start from last month's recurring revenue, add new customers and expansion from existing ones, and subtract revenue lost to cancellations. Annual recurring revenue is ending MRR times twelve.
ending MRR = start + new + expansion − churned
NRR looks only at the customers you began with: start plus expansion minus churn, over start. Above 100% means existing customers alone grew your revenue.
