Why small SaaS needs metric discipline
SaaS businesses live or die by unit economics. Unlike a one-time-sale business where you mostly need to know if you're profitable today, SaaS requires forecasting cash flows years in advance based on retention, expansion, and acquisition assumptions. Get the metrics wrong and you'll either under-invest (slowing growth) or over-invest (running out of cash) — both fatal.
The good news: you don't need a CFO or 50 metrics. You need 10, tracked rigorously, on one dashboard.
The 10 essentials
1. MRR (Monthly Recurring Revenue)
The foundational metric. See the full MRR tracking guide [blocked].
2. MRR growth rate (month-over-month)
(MRR this month − MRR last month) / MRR last month. Healthy early-stage SaaS targets 10-15% MoM. Mature SaaS targets 5-8% MoM.
3. Gross MRR churn rate
Churned MRR / starting MRR. Should be under 3% monthly for SMB-focused SaaS, under 1% monthly for enterprise SaaS.
4. Net Revenue Retention (NRR)
(Starting MRR + Expansion MRR − Contraction MRR − Churned MRR) / Starting MRR. Above 100% is the goal; 110%+ is best-in-class for SMB SaaS.
5. Customer Acquisition Cost (CAC)
Fully-loaded sales and marketing spend / new customers acquired in the period. "Fully-loaded" means salaries, tools, ads, content costs — everything you spent to acquire customers.
6. CAC payback period
CAC / (Average MRR per customer × gross margin %). The number of months until a customer's gross profit pays back acquisition cost. Healthy SMB SaaS: under 18 months. Enterprise SaaS: under 24 months.
7. LTV-to-CAC ratio
LTV / CAC. Target: 3:1 or higher. See the full LTV guide [blocked].
8. Gross margin
(Revenue − hosting + support + payment processing costs) / Revenue. Healthy SaaS gross margin: 70-85%. If yours is below 60%, your cost structure needs attention before you scale.
9. Magic number
Net new ARR added in the quarter / Sales & Marketing spend in the previous quarter. Above 0.75 is healthy; above 1.0 means you should aggressively reinvest in growth; below 0.5 means your acquisition engine is broken.
10. Burn multiple
Net cash burned / Net new ARR added. Below 1 is excellent (efficient growth); 1-2 is acceptable; above 2 means you're inefficiently burning cash for growth.
