Every SaaS metrics guide on the first page of Google is written for finance teams at companies with a real CFO. They give you 35 metrics, 8 dashboards, and no sense of which 4 actually matter when you are a solo founder at $2K MRR.
This guide is the honest version for indie founders. We track these exact metrics on our own platform (BetterLaunch.co, DR 47 SaaS), and we talk to founders weekly about what they measure and what they ignore. Here is what matters at each stage and what to skip.
#TL;DR
- 35 SaaS metrics exist. You need 5 at any given stage. The rest are noise.
- Pre-revenue: track signups + activation + day-7 retention.
- $1K to $10K MRR: add MRR growth rate + net revenue churn.
- $10K to $100K MRR: add CAC, LTV, LTV:CAC ratio, payback period.
- Above $100K MRR: start tracking Net Revenue Retention (NRR), gross margin, Rule of 40.
- Your one most important metric at any stage is the one directly tied to the next milestone. Everything else is a distraction.
#The stage-appropriate metric stack
Different stages need different metrics. Pick the right 5 for where you are.
#Stage 0, Pre-revenue (before you have paid users)
Most indie founders at this stage obsess over vanity metrics (followers, waitlist size). The metrics that matter:
- Signups per week. Is the number growing?
- Activation rate. What percentage of signups hit your "aha" moment within 7 days?
- Day 7 retention. What percentage of activated users are still active at day 7?
- Qualitative feedback volume. How many users are sending detailed, unsolicited feedback?
- Paying conversion (if you are charging). What percentage of signups convert to paid within 30 days?
If activation < 30% or D7 retention < 30%, doing more marketing is wasted. Fix the product first. SaaS Onboarding and Beta Launch Guide cover the tactical fixes.
#Stage 1, $1K to $10K MRR (first product-market fit signals)
At this scale, add:
- MRR and MRR growth rate (month-over-month).
- Net revenue churn (see below).
- Activation rate still tracked.
- Day 30 retention.
- Revenue per paying customer.
Benchmarks for indie SaaS at this stage:
- MRR growth rate: 5 to 20% MoM is healthy. Below 5% = slow; investigate.
- Gross churn: under 5% monthly is healthy for B2B; under 8% for B2C.
- D30 retention of new users: 40%+ is healthy.
#Stage 2, $10K to $100K MRR (real business scale)
Add the efficiency metrics:
- CAC (customer acquisition cost).
- LTV (customer lifetime value).
- LTV:CAC ratio (target 3:1 or better).
- Payback period (months to recover CAC; target under 12 for indie, under 18 for enterprise).
- Net MRR (new + expansion - churned - downgraded).
At this scale, paid acquisition becomes viable. But only if you know your LTV and payback period with confidence.
#Stage 3, $100K+ MRR (optimization scale)
Add:
- Net Revenue Retention (NRR). Expansion minus churn. Target: 100%+ (meaning existing cohorts grow over time).
- Gross margin. (Revenue - COGS) / Revenue. SaaS target: 70%+; cloud-heavy SaaS can be lower.
- Rule of 40. Growth rate + profit margin. Public SaaS target is 40+; indie SaaS at this scale 30+.
- Cohort retention curves. LTV diverges wildly by cohort; segmented analysis matters.
#The 9 metrics explained simply
#1. Monthly Recurring Revenue (MRR)
The total predictable, recurring monthly revenue from your subscribers. Excludes one-time fees.
Formula: MRR = sum(monthly subscription revenue from each active customer)
If a customer is on an annual plan for $1,200/year, they contribute $100/month to MRR.
What matters: MRR growth rate over time, split into components (new MRR, expansion MRR, churned MRR, downgraded MRR).
#2. Annual Recurring Revenue (ARR)
Simply MRR × 12. Used mostly for enterprise SaaS and reporting.
#3. Customer Acquisition Cost (CAC)
Total sales + marketing spend divided by new customers acquired in the same period.
Formula: CAC = (sales + marketing spend) / new customers
For indie SaaS, track blended CAC (all channels) and paid CAC (only paid channels). The gap between them tells you how much free distribution you are getting.
Benchmarks for indie B2C SaaS: $10 to $80. Benchmarks for indie B2B SaaS: $50 to $400.
#4. Lifetime Value (LTV)
How much revenue an average customer generates during their time with you.
Simple formula: LTV = ARPU / churn rate
Where ARPU is average revenue per user per month, and churn is monthly churn rate (as a decimal).
Example: ARPU $30/month, monthly churn 5% → LTV = $30 / 0.05 = $600.
#5. LTV:CAC ratio
LTV divided by CAC. The cleanest measure of unit economics.
Benchmarks:
- Below 1:1: losing money per customer. Not sustainable.
- 1:1 to 3:1: marginally workable; cash flow pressure.
- 3:1 to 5:1: healthy.
- Above 5:1: often means you are under-investing in growth; could spend more on acquisition.
#6. Payback Period
Months to recover CAC from a new customer.
Formula: Payback = CAC / (ARPU × gross margin)
Targets:
- Indie B2C: under 6 months.
- Indie B2B: under 12 to 18 months.
- Enterprise: under 24 months typically acceptable.
#7. Churn
Percentage of customers or revenue lost per period. Two types:
- Logo churn (or customer churn): % of customers who cancel.
- Revenue churn: % of MRR lost.
Gross churn = churned MRR / starting MRR. Ignores expansion. Net revenue churn = (churned + downgraded - expansion) / starting MRR. Can be negative (great) if expansion outpaces churn.
Benchmarks for indie SaaS:
- Monthly gross churn: 2% excellent, 5% average, 10%+ concerning.
- Annual gross churn: 10-20% normal for indie; 5-10% exceptional.
#8. Net Revenue Retention (NRR)
The growth of existing customer cohorts over time. Includes upgrades, cross-sells, expansion.
Formula: NRR = (starting MRR + expansion - churn - downgrade) / starting MRR
Benchmarks:
- Under 90%: cohorts are shrinking; churn problem.
- 100%: cohorts stable.
- 110%+: expansion outpaces churn (the dream for SaaS).
#9. Activation rate
Percentage of signups who reach a defined "aha" moment. Your own definition, but it needs to predict retention.
Good example: "user created their first project and invited one teammate." Bad example: "user logged in."
Benchmarks for indie SaaS:
- Under 20%: product / onboarding problem.
- 20 to 40%: healthy indie range.
- 40%+: exceptional.
#Metrics to skip (at least until you have a team)
Gross Revenue Retention (GRR) as separate from NRR. Related; skip one for simplicity unless you have finance reporting needs.
Magic number. Enterprise metric about sales efficiency; not meaningful at indie scale.
Quick ratio (bessemer's). Useful for VC-backed SaaS reporting; adds little for bootstrapped founders.
Burn multiple. Relevant only for VC-funded companies.
CAC by channel with full multi-touch attribution. Valuable but expensive to build; use simple last-touch for indie.
NPS / CSAT polls on every touch. Useful in aggregate once you have 100+ customers; noisy before.
#How to build a minimal SaaS metrics dashboard
For indie founders, a simple dashboard is one page with 5 numbers, updated weekly.
Recommended stack:
- Stripe or Paddle for revenue data.
- PostHog or Amplitude (free tier) for product events (signups, activation, retention).
- A spreadsheet for weekly manual review.
- ChartMogul, Baremetrics, or ProfitWell only once revenue passes $5K MRR. Before that, a spreadsheet is fine.
One founder's actual dashboard at $8K MRR:
- MRR (current): $8,240
- MRR MoM growth: +12.1%
- New signups this week: 47
- Activation rate: 34%
- Monthly gross churn: 4.2%
Five numbers. Five minutes to read. No wasted attention.
#Real benchmarks for indie SaaS (not enterprise numbers)
Most SaaS metrics articles cite public-company benchmarks (20%+ NRR, 120% NRR, 50% Rule of 40). Those are not the right reference for a 2-person SaaS at $20K MRR.
Realistic indie SaaS benchmarks:
Year 1 (building to $10K MRR):
- MRR MoM growth: 10 to 20%.
- Monthly churn: 5 to 10% is acceptable.
- Activation: 25 to 40%.
- D30 retention: 30 to 50%.
- LTV:CAC: often not measurable; just make sure you are not lighting money on fire.
Year 2 ($10K to $50K MRR):
- MRR MoM growth: 5 to 15%.
- Monthly gross churn: 3 to 7%.
- LTV:CAC: 3:1 target.
- Payback: 12 to 18 months.
Year 3+ ($50K+ MRR):
- MRR MoM growth: 3 to 10%.
- Net revenue churn: approaching neutral or negative.
- NRR: 95 to 110%.
- LTV:CAC: 4:1+.
Below these numbers, focus on retention and activation, not acquisition. Above these numbers, you can invest confidently in scaling.
#The single most important metric by stage
If you had to track one number:
- Pre-revenue: activation rate.
- $1K to $10K MRR: MRR growth rate.
- $10K to $100K MRR: payback period.
- $100K+ MRR: net revenue retention.
Everything else is supporting context.
#Common mistakes in SaaS metrics tracking
Tracking too many things. 35-metric dashboards are pretty; nobody uses them.
Not segmenting by cohort. Aggregate churn hides big differences between cohorts. Always segment by signup month.
Confusing revenue with profit. MRR is top-line; margins matter at scale.
Counting trials or free users as "customers." Keeps LTV inflated and CAC misleading.
Ignoring expansion revenue. Existing customer growth is usually the cheapest revenue.
Reporting gross numbers without context. "5% churn" means nothing without knowing the customer base size and pricing.
Changing metric definitions without flagging it. A quiet switch from "signup" to "verified email" breaks month-over-month comparisons.
#Tools we recommend
- Stripe Sigma or Paddle Data: clean, first-party revenue data. Free for users of those platforms.
- ChartMogul / Baremetrics / ProfitWell: dedicated SaaS metric dashboards. Worth the $100 to $500/month after $10K MRR.
- PostHog or Amplitude: product analytics for activation and retention.
- Google Sheets: surprisingly good for indie SaaS; versioning and manual review discipline matters more than tool sophistication.
#FAQ
What is MRR? Monthly Recurring Revenue. The predictable monthly subscription revenue from all active paying customers. Excludes one-time charges.
How is LTV calculated? Simplest formula: LTV = ARPU / churn rate. More sophisticated versions factor in expansion revenue and gross margin.
What is a good SaaS churn rate? Monthly gross churn under 5% is healthy for most indie SaaS. Under 2% is exceptional. Above 10% is a retention or ICP problem.
What LTV:CAC ratio should I target? 3:1 is the standard healthy target. Below 1:1 is unsustainable. Above 5:1 often indicates underinvestment in growth.
What is Net Revenue Retention (NRR)? Revenue retained from an existing cohort including expansion, minus churn and downgrades. Above 100% means cohorts grow over time.
Do I need NRR at $5K MRR? No. NRR is for scale. At under $50K MRR, gross revenue churn and activation are more actionable.
What is the Rule of 40? Growth rate + profit margin. Public SaaS companies target 40+. Indie SaaS at scale 30+ is healthy.
How often should I review my SaaS metrics? Weekly for indie founders. Monthly deep-dive for trends. Quarterly for strategic decisions.
What is ARPU? Average Revenue Per User. Total revenue divided by active paying customers.
What is the difference between gross and net churn? Gross churn counts only customers or revenue lost. Net churn nets out expansion from existing customers; can be negative if expansion outpaces churn (ideal).
#Summary
Tracking SaaS metrics well is about picking the right 5 for your stage, ignoring the rest, and reviewing weekly.
- Pre-revenue: activation, D7 retention, signups.
- $1K to $10K MRR: add MRR growth, gross churn.
- $10K to $100K MRR: add CAC, LTV:CAC, payback.
- $100K+ MRR: add NRR, Rule of 40.
For most indie founders, the most productive move is to simplify the dashboard to 5 numbers on one page and look at them every Friday for 10 minutes. Everything else is noise until scale justifies the complexity.
