What Is Revenue Churn (MRR Churn)? Formula & Benchmarks
Revenue churn (also called MRR churn) is the percentage of recurring revenue your SaaS business loses over a given period from cancellations and downgrades. While customer churn tells you how many people left, revenue churn tells you how much money left — which is usually the more important number for SaaS businesses with multiple pricing tiers.
Quick Answer
Gross Revenue Churn = ((MRR Churned + MRR Contracted) ÷ MRR at Start) × 100
Healthy target: below 4% monthly. Enterprise: below 2%.
Revenue Churn vs Customer Churn
Customer churn measures the percentage of customers who cancelled. Revenue churn measures the percentage of recurring revenue lost. These can tell very different stories:
- If revenue churn is higher than customer churn, you are disproportionately losing high-value customers — a red flag for enterprise retention.
- If revenue churn is lower than customer churn, you are losing small customers but retaining large ones — generally a healthier pattern.
Always track both metrics together. The gap between them reveals whether your churn problem is concentrated in specific customer segments.
How to Calculate Revenue Churn
Gross Revenue Churn Formula
Gross Revenue Churn = ((MRR Churned + MRR Contracted) ÷ MRR at Start) × 100
Example: Starting MRR = $40,590. Churned MRR = $1,780 (customers who cancelled). Contracted MRR = $640 (customers who downgraded). Gross revenue churn = (($1,780 + $640) ÷ $40,590) × 100 = 5.97%.
Gross vs Net Revenue Churn
Gross revenue churn only counts losses. Net revenue churn subtracts expansion revenue from those losses, which can make the number smaller or even negative:
Net Revenue Churn Formula
Net Revenue Churn = ((MRR Churned + MRR Contracted − MRR Expanded) ÷ MRR at Start) × 100
Example: Using the same numbers plus $2,800 in expansion MRR. Net revenue churn = (($1,780 + $640 − $2,800) ÷ $40,590) × 100 = (−$380 ÷ $40,590) × 100 = −0.9%.
Negative net revenue churn means your existing customers are growing faster than they are churning — the holy grail of SaaS. This is equivalent to NRR above 100%.
Revenue Churn Benchmarks by Stage
| Stage | Gross Rev. Churn | Target Net Rev. Churn |
|---|---|---|
| Seed / Pre-Seed | < 7% | < 3% |
| Series A | < 5% | < 1% |
| Series B+ | < 4% | Negative |
| Enterprise | < 2% | Negative |
How to Reduce Revenue Churn
- Focus on high-value customer retention. If revenue churn exceeds customer churn, your enterprise customers are leaving. Invest in customer success for your top accounts.
- Offer mid-tier plans. Give downgraders a place to go before they cancel entirely. A mid-tier plan converts contraction into retained revenue.
- Drive expansion to offset losses. If gross churn is hard to reduce, focus on expansion MRR to make net revenue churn negative.
- Fix involuntary churn. Implement dunning sequences and card updater services to prevent payment failures from causing revenue loss.
- Monitor revenue at risk. Track accounts with declining seat counts or usage trends and intervene before they downgrade or cancel.
Common Revenue Churn Mistakes
Common Mistake
Using the ending MRR as the denominator instead of the starting MRR. This understates churn because the ending MRR includes new customer revenue that was not at risk. Always divide by the starting MRR.
Common Mistake
Mixing gross and net revenue churn. Be explicit about which you are reporting. Gross revenue churn only counts losses. Net revenue churn subtracts expansion. Confusing the two leads to misleading benchmarks and bad decisions.
