What your result means (before you calculate)
MRR is monthly recurring revenue from subscriptions—sum each active customer’s monthly price (normalize annual deals to a monthly equivalent). Track new, expansion, contraction, and churn components separately.
Worked example (MRR stack)
Start $50k MRR, add $8k new, $2k expansion, lose $3k churn → ending MRR = 50 + 8 + 2 − 3 = $57k (+14% net growth).
