Subscription Metrics Overview: The Numbers Every Subscription Business Must Track
A guide to the core metrics for subscription businesses — MRR, churn, LTV, CAC ratio — and how to monitor them in AskBiz.
Why Subscription Metrics Are Different
Subscription businesses look fundamentally different from transactional businesses in their financial data. Revenue is recognised monthly rather than on purchase; a churned customer is a permanent loss of future revenue, not just one lost sale; and growth is the compounding result of acquisition minus churn.
The standard P&L and transactional eCommerce metrics — revenue per order, conversion rate, average basket — do not capture the health of a subscription business. You need a different set of metrics.
The Six Core Subscription Metrics
1. MRR (Monthly Recurring Revenue): total predictable monthly revenue from active subscriptions. The primary growth metric.
2. ARR (Annual Recurring Revenue): MRR × 12. Used for business valuation and investor communication.
3. Churn Rate: percentage of MRR or subscribers lost in a period. The primary health metric.
4. Net Revenue Retention (NRR): total MRR from the existing customer base at end of period ÷ MRR at start of period. Includes expansion (upgrades) and contraction (downgrades). NRR > 100% means your existing customers are growing in value — the gold standard.
5. Customer Lifetime Value (LTV): average revenue per customer over their entire subscription lifetime. LTV = ARPU ÷ Churn Rate.
6. CAC:LTV Ratio: LTV ÷ Customer Acquisition Cost. Should be at least 3:1 for a sustainable subscription business.
Viewing Subscription Metrics in AskBiz
If you have Stripe or another subscription payment processor connected, AskBiz automatically tracks:
- MRR and ARR (with growth trend)
- Monthly churn rate (subscriber churn and revenue churn)
- ARPU (average revenue per user)
- New MRR, expansion MRR, contraction MRR, churned MRR
- Net Revenue Retention
Go to Dashboard → Subscription to access your subscription analytics view. If you use multiple payment processors, connect all of them at /sources to get a unified view.
You can also ask AskBiz: *'What is my MRR growth rate over the last 6 months?'* or *'What is my net revenue retention this quarter?'*
The Subscription Growth Engine
MRR growth = New MRR + Expansion MRR − Churned MRR − Contraction MRR
This decomposition matters because the levers are different:
- New MRR is driven by acquisition (marketing, sales, product)
- Expansion MRR is driven by upsell and cross-sell
- Churned MRR is reduced by retention (product quality, engagement, customer success)
- Contraction MRR is reduced by pricing strategy and plan tier design
A business with flat total MRR may have strong new MRR that is exactly offset by churn — which is very different from a business with flat MRR because of no growth and no churn. AskBiz shows all four components so you can see exactly what is driving the headline number.
Benchmarks for Subscription Businesses
Healthy benchmarks vary by business type, but general SME subscription benchmarks:
| Metric | Good | Warning zone |
|---|---|---|
| Monthly churn | < 2% | > 5% |
| Net Revenue Retention | > 100% | < 90% |
| CAC:LTV ratio | > 3:1 | < 2:1 |
| ARPU trend | Growing | Declining |
B2B subscriptions typically have lower churn (1–3%) than B2C (3–8%) because switching costs are higher. If your metrics are in the warning zone, use AskBiz churn intelligence to identify which segments or cohorts are driving the problem.
