What gets measured gets managed. If you're not tracking your SaaS metrics, you're flying blind.
Most founders obsess over vanity metrics (total users, signups) while ignoring the metrics that actually predict success (retention, LTV, unit economics). This is a mistake.
In my two exits, I tracked 12 core metrics religiously. They told me what was working, what was breaking, and when to pivot. Here are the 12 metrics every SaaS founder must track in 2026.
The 12 Core SaaS Metrics
1. MRR (Monthly Recurring Revenue)
The money you expect to make every month from your current customer base.
2. ARR (Annual Recurring Revenue)
MRR multiplied by 12. Your projected annual revenue from current customers.
3. Churn Rate (Monthly)
What percentage of customers you lose each month.
4. LTV (Customer Lifetime Value)
Total revenue you'll make from a customer over their entire relationship with you.
5. CAC (Customer Acquisition Cost)
How much you spend (on average) to acquire one customer.
6. LTV:CAC Ratio
The ratio of how much you'll make vs how much you spend to acquire customers.
7. NRR (Net Revenue Retention)
Whether existing customers are expanding (paying more) or shrinking (paying less) compared to churn.
8. ARPU (Average Revenue Per User)
Average monthly revenue you make per customer.
9. Conversion Rate (Trial to Paid)
What percentage of your free trial users become paying customers.
10. Payback Period
How many months until a customer pays back your acquisition cost.
11. Burn Rate & Runway
How much cash you're spending monthly and how long until you run out.
12. Feature Adoption & Usage
What percentage of customers use your core features and how often.
The Golden Rule: Track these 12 metrics. Review them every week. Make decisions based on the data, not your gut.
How to Set Up Tracking
You don't need sophisticated analytics software to start. A spreadsheet is fine.
The Minimum Tracking Stack
- Stripe: Billing and payments. Tracks MRR, ARR, churn, customers
- Google Analytics: Website traffic and conversion rates
- Segment or Mixpanel: Product usage tracking (feature adoption)
- Google Sheets: Manual tracking of the 12 metrics weekly
That's it. Stripe + Google Sheets + basic analytics = complete metrics dashboard.
The Spreadsheet Template
Create 12 rows (one per metric). Add 52 columns (one per week). Fill in the numbers every Monday morning.
Graph it. The trend is more important than the absolute number. Is MRR growing? Is churn decreasing? Is LTV increasing?
Benchmarks: Is Your Business Healthy?
Here's what healthy looks like for a SaaS at different stages:
Stage 1: Pre-Product-Market Fit (<$10K MRR)
- MRR: Growing >15% month-over-month
- Churn: <10% monthly (could be higher, you're learning)
- CAC: <$500 (you're bootstrapped, doing cold email)
- LTV:CAC: >2:1
- Conversion: 5-10% trial to paid
Stage 2: Product-Market Fit ($10K-$50K MRR)
- MRR: Growing 10-20% month-over-month
- Churn: <5% monthly
- CAC: <$300
- LTV:CAC: >3:1
- NRR: >100%
- Conversion: 8-12% trial to paid
Stage 3: Scale ($50K+ MRR)
- MRR: Growing 5-10% month-over-month
- Churn: <3% monthly
- CAC: <$200 (paying for growth)
- LTV:CAC: >5:1
- NRR: >120%
- Payback period: <3 months
Red Flags: When Something Is Broken
Rising Churn: Your product isn't solving the problem or customers found a better solution. Stop all growth activities. Fix the product.
Declining ARPU: Customers are downgrading or switching to cheaper tiers. Either your positioning is wrong or price is too high. Survey customers.
Rising CAC: Your acquisition channels are becoming saturated or paid ads are getting expensive. Time to diversify channels.
LTV:CAC <2:1: Your unit economics are broken. You're losing money on every customer. Fix pricing, reduce churn, or get cheaper acquisition before growing.
Low Feature Adoption: Customers aren't using your core features. Either they don't understand how, or the feature isn't as valuable as you thought. Improve onboarding or cut the feature.
The brutal truth: If any of these red flags appear, stop hiring, stop marketing, and fix the product. Most founders ignore these signals and continue growing. That's how good companies die.
The Weekly Review Process
Every Monday morning, I review these metrics:
- Has MRR grown? If not, why?
- Did anyone churn? Can I call them and understand why?
- How many new customers this week?
- What's my CAC? Is it trending up or down?
- What's my payback period? Is it improving?
- Are customers using my new feature?
- How many days of runway do I have?
This 15-minute review tells you everything. Don't wait for monthly board meetings or quarterly reviews. Weekly is the cadence.
Tools to Automate Tracking
As you scale, upgrade to dedicated analytics:
- Metabase: Self-hosted, free analytics. Connect to your database
- Amplitude: Product analytics. Tracks feature adoption and user behavior
- Chartmogul: SaaS-specific metrics. Tracks MRR, ARR, churn automatically
- Baremetrics: Simple SaaS metrics dashboard. Stripe integration
Start with the spreadsheet. Move to Baremetrics at $20K MRR. Add Amplitude at $50K MRR.

Final Thoughts
Metrics are your truth. They don't lie. Your gut will lie to you. Your friends will lie to you (to be nice). Your metrics never lie.
Track the 12 metrics. Review weekly. Act on what you see. If something is broken, fix it immediately. If something is working, double down.
This discipline separated my successful companies from the failures. The difference wasn't product vision or market timing. It was data discipline.
