The 12 SaaS Metrics Every Founder Must Track in 2026
Most early-stage SaaS founders track too few metrics (just revenue) or too many (every vanity stat the dashboard shows). Neither works. The right set of metrics gives you a real-time diagnostic of your business health — telling you where growth is coming from, where it’s leaking, and where to invest next. Here are the 12 metrics that matter, how to calculate them, and what benchmarks to target.
Revenue Metrics
1. MRR — Monthly Recurring Revenue
What it is: The predictable, recurring revenue your business generates each month from active subscriptions.
How to calculate: Sum of all active subscriber monthly fees. For annual subscribers, divide their annual fee by 12 to get monthly equivalent.
Break it down into: New MRR (from new customers), Expansion MRR (upgrades/upsells), Contraction MRR (downgrades), Churned MRR (cancellations). Net New MRR = New + Expansion – Contraction – Churned.
Benchmark: Early-stage: any consistent upward trend. Growth stage: 15–20% MoM growth is strong. Series A typical: $50K–$500K MRR.
2. ARR — Annual Recurring Revenue
What it is: MRR × 12. The annualized view of your recurring revenue base. More commonly referenced than MRR when talking to investors or board members.
Benchmark: $1M ARR is the first major milestone for most SaaS startups. $10M ARR is the next. $100M ARR is category leadership.
3. ARPU — Average Revenue Per User
What it is: MRR ÷ total number of paying customers. Tells you the average monthly value of a customer.
Why it matters: Increasing ARPU (through upsells, seat expansion, or pricing adjustments) is often a faster path to growth than acquiring new customers. Track ARPU by cohort and segment to see which customers are most valuable.
Growth Metrics
4. Churn Rate
What it is: The percentage of customers (or revenue) lost in a given period. Two types:
- Customer churn: Customers lost ÷ customers at start of period
- Revenue churn: MRR lost from cancellations ÷ MRR at start of period
Benchmark: SMB SaaS: under 5% monthly customer churn. Mid-market: under 2% monthly. Enterprise: under 1% monthly. Revenue churn of under 1% monthly with positive net revenue retention is the goal.
Critical insight: Even small differences in churn rate have enormous compounding effects. Going from 5% to 3% monthly churn means you retain 64% vs 54% of customers after 12 months — a 10-point difference that compounding makes dramatic at scale.
5. NRR — Net Revenue Retention
What it is: The percentage of recurring revenue retained from existing customers, including expansions. Formula: (Starting MRR + Expansion – Contraction – Churn) ÷ Starting MRR × 100.
Why it matters: NRR above 100% means your existing customer base is growing revenue even without new customer acquisition. This is the holy grail of SaaS economics.
Benchmark: Under 90% = serious problem. 90–100% = average. 100–110% = good. 110–130% = excellent (Slack, Datadog territory). Above 130% = best-in-class.
6. MoM Growth Rate
What it is: Month-over-month MRR growth percentage. (MRR this month – MRR last month) ÷ MRR last month × 100.
Benchmark: Pre-product-market-fit: anything positive. Post-PMF: 10–20% MoM is strong. “T2D3” (triple, triple, double, double, double ARR over 5 years) is the benchmark growth trajectory for top-tier SaaS.
Unit Economics
7. CAC — Customer Acquisition Cost
What it is: Total sales and marketing spend ÷ number of new customers acquired in the same period.
Common mistake: Most founders undercount CAC by omitting salaries. Include all marketing spend, sales team salaries, tools, and agency fees. Be honest about the full cost to acquire a customer.
Track by channel: CAC from SEO is different from CAC from paid ads. Understanding channel-level CAC helps you allocate budget to the most efficient acquisition channels.
8. LTV — Customer Lifetime Value
What it is: The total revenue you expect to earn from a customer over their lifetime. Simple formula: ARPU ÷ Monthly Churn Rate. For a customer paying $100/month with 5% monthly churn, LTV = $100 ÷ 0.05 = $2,000.
More accurate formula: Gross Margin % × ARPU ÷ Churn Rate — this gives you the profit-adjusted LTV, which is what you should actually compare to CAC.
9. LTV:CAC Ratio
What it is: LTV divided by CAC. The single most important unit economics ratio in SaaS.
Benchmark: Under 1:1 = destroying value. 1:1 = breaking even. 3:1 = healthy. 5:1+ = very efficient (though might signal you’re underinvesting in growth). Most VC-backed SaaS targets 3:1 as the floor.
10. CAC Payback Period
What it is: How many months until you recover your customer acquisition cost. CAC ÷ (ARPU × Gross Margin %).
Benchmark: Under 12 months is strong. 12–18 months is acceptable for most SaaS. Above 24 months creates cash flow risk — you’re spending money today to recover it two years from now.
Engagement Metrics
11. DAU/MAU Ratio
What it is: Daily Active Users ÷ Monthly Active Users. Measures how “sticky” your product is — what percentage of monthly users engage daily.
Benchmark: Consumer products aim for 50%+. SaaS B2B: 20–40% is healthy depending on use case. A project management tool used daily should hit 40%+. A tool used weekly (payroll, tax) might naturally be 15%.
Why it matters: Low DAU/MAU signals customers aren’t building habits with your product — they’re at higher churn risk. This is your earliest warning of retention problems.
12. NPS — Net Promoter Score
What it is: The percentage of customers who would recommend your product (9–10 on a 10-point scale) minus the percentage who are detractors (0–6). Ranges from -100 to +100.
Benchmark: Under 0 = serious problem. 0–30 = acceptable. 30–50 = good. 50–70 = excellent. Above 70 = world-class (Apple, Tesla territory). SaaS average is around 30–40.
How to use it: Survey customers after their 30th day and after each major milestone. Follow up with every detractor personally — their feedback is your product roadmap. Follow up with promoters — they’re your referral engine.
Building Your Metrics Dashboard
Don’t just track these — display them in a single dashboard you review every Monday morning. The discipline of weekly review forces you to notice trends before they become crises. Tools: ChartMogul (revenue metrics), Mixpanel (product engagement), Stripe Revenue Recognition (MRR calculation), or a custom PostgreSQL dashboard if you’re running on FastAPI like Messenjo.
