Example
Using the default inputs, the result is:
$12,000.00
- New MRR
- $12,000
- Expansion MRR
- $8,000
- Contraction MRR
- $3,000
- Churned MRR
- $5,000
- Starting MRR (optional)
- $0
- Period length (months)
- 1
- Target net new MRR (optional)
- $0
How to calculate
- Measure new MRR from new customers in the period.
- Measure expansion MRR from existing customers.
- Subtract contraction MRR and churned MRR.
- Net new MRR is the net change in MRR for the period.
Formula
Net new MRR = new + expansion - contraction - churn
- All components are measured over the same time window.
- New MRR excludes expansions from existing customers.
FAQ
Is net new MRR the same as MRR growth rate-
Net new MRR is a dollar amount (change in MRR). Growth rate is net new MRR divided by starting MRR for the period.
Common mistakes
- Mixing invoiced revenue or cash with MRR movements.
- Comparing months without considering annual billing seasonality.
How to interpret
How to use net new MRR
- Track by segment to see which motions produce durable growth.
- Watch churned MRR trends to avoid growth hiding retention issues.
- Pair with CAC and payback to judge growth efficiency.
