Every article about metrics tells you to track everything. The result: founders drowning in dashboards, checking 15 numbers each morning and acting on none of them. This guide does the opposite. Here are the 12 metrics that actually predict whether your business will succeed — and the 5 you can safely ignore.
The 12 metrics that matter
1. Monthly Recurring Revenue (MRR)
The single most important number for a subscription business. Watch it weekly, understand the components: new MRR, expansion MRR, churned MRR, reactivation MRR. A flat MRR with high new MRR and high churn MRR is a warning sign even though the headline looks fine.
2. Net Revenue Retention (NRR)
NRR above 100% means your existing customers are growing their spend faster than they're churning. It's the single best leading indicator of long-term business health. World-class SaaS companies have NRR of 120%+.
3. Monthly Churn Rate
As discussed — the percentage of MRR lost each month from cancellations. Target: under 2% for B2C, under 1% for B2B. Review it monthly, not quarterly.
4. Customer Acquisition Cost (CAC)
Total marketing + sales spend divided by new customers acquired. Most founders calculate this wrong because they forget to include their own time. If you're spending 20 hours a week on content marketing, that time has a cost.
5. LTV:CAC Ratio
If it costs you $200 to acquire a customer who pays you $600 over their lifetime, your LTV:CAC is 3:1 — generally the minimum threshold for a healthy SaaS business. Under 3:1 and you're burning money on growth.
6. Payback Period
How many months does it take to recover your CAC through gross margin? Under 12 months is healthy for most SaaS businesses. Over 18 months means you need more capital to scale.
7. Daily Active Users / Monthly Active Users (DAU/MAU)
For product businesses, engagement ratio is a proxy for value delivery. If your DAU/MAU is 20% (1 in 5 monthly users are daily users), it's a strong signal of habit formation.
8. Activation Rate
Of users who sign up, what percentage reach your "aha moment"? This varies by product, but improving activation rate often has more impact than improving acquisition.
9. Revenue per Employee (if you have a team)
A useful north-star for efficiency. Top SaaS companies generate $200k–$400k+ revenue per employee. For solo founders this is automatically excellent.
10. Gross Margin
Software businesses should target 70–85% gross margin. If your gross margin is under 60%, your unit economics are concerning and you have limited room for reinvestment.
11. Ad ROAS (if you run paid ads)
Return on Ad Spend. For most bootstrapped founders, you want at least 3x ROAS to be profitable after taking into account all other costs. Below 2x and you're likely losing money on paid acquisition.
12. Cash Runway
If you're pre-profitable: how many months of operating expenses do you have in the bank? Keep at least 6 months. 12 months gives you room to experiment and pivot.
The 5 metrics to stop tracking
1. Total registered users
Meaningless without activation and retention context. A million registered users with 5% activation is worse than 10,000 users with 60% activation.
2. Pageviews
Unless you're a media business. Pageviews correlate weakly with revenue for SaaS businesses.
3. Twitter/social followers
Distribution is valuable. Followers are a proxy. Track email list growth instead — that's the distribution channel you own.
4. Product Hunt / Hacker News upvotes
Great for a 24-hour dopamine hit. Essentially uncorrelated with long-term business success.
5. Revenue run rate when you have under $5k MRR
Annualising $3k MRR as "$36k ARR" is technically accurate and psychologically misleading. At early stage, work with the actual monthly number — it keeps you grounded.
