When to Use This Skill

Use this skill when you need to:

• Run monthly business health checks to track progress
• Benchmark metrics against relevant peer ranges for your segment
• Diagnose growth problems (stuck at plateau, high churn, poor unit economics)
• Calculate missing metrics from partial data
• Identify red flags requiring immediate attention
• Get actionable recommendations for metric improvement
• Prepare for fundraising or acquisition (know your numbers)

Core Concepts

The 5 Metric Categories

1. Revenue Health (25% weight): MRR, ARR, ARPU
2. Unit Economics (25% weight): LTV, CAC, LTV:CAC, payback period
3. Retention Health (25% weight): Monthly/annual churn, NRR
4. Efficiency (15% weight): Gross margin, profit margin
5. Growth (10% weight): MoM growth, viral coefficient

Quick Health Assessment

Step-by-Step Analysis Process

Step 1: Gather Your Metrics

Collect any of these you have available:

• Monthly Recurring Revenue (MRR)
• Customer count
• Monthly churn rate
• Customer Acquisition Cost (CAC)
• Average Revenue Per User (ARPU)
• Gross margin percentage

Step 2: Calculate Missing Metrics

ARPU (if you have MRR and customers):

ARPU = MRR ÷ Total customers

LTV (if you have ARPU, margin, churn):

LTV = (ARPU × Gross Margin %) ÷ Monthly churn rate

LTV:CAC (if you have LTV and CAC):

LTV:CAC = LTV ÷ CAC

CAC Payback (if you have CAC, ARPU, margin):

Payback = CAC ÷ (ARPU × Gross Margin %)

Annual churn (if you have monthly; use monthly churn as decimal):

Annual = (1 - (1 - Monthly)^12) × 100

Step 3: Benchmark Against Peer Ranges

Use the benchmark ranges below as directional guidance, not universal truth. Segment (SMB vs enterprise), price point, geography, and channel mix all matter.

Step 4: Identify Red Flags and Strengths

Flag metrics outside healthy ranges and highlight areas of strength.

Step 5: Generate Recommendations

Prioritize actions by impact: churn → pricing → acquisition → operations.

Metric Deep Dives

Revenue Metrics

Monthly Recurring Revenue (MRR)

What it measures: Predictable monthly revenue from subscriptions

Benchmarks (directional for subscription SaaS):

Red flags:

• ❌ Below $1K MRR after 6 months (possible PMF or distribution issues)
• ❌ Stuck at $3K-$5K for 3+ months (growth plateau)
• ❌ Declining for 2+ consecutive months

Strengths:

• ✅ Reaching $10K MRR in <18 months
• ✅ Consistent month-over-month growth

Average Revenue Per User (ARPU)

What it measures: Average monthly revenue per customer

Benchmarks (segment-sensitive):

Red flags:

• ❌ ARPU low relative to CAC and support burden
• ❌ ARPU declining over time

Improvement levers:

• Introduce tiered packaging and pricing
• Add annual payment discounts
• Implement usage-based pricing
• Raise prices on new customers first

Unit Economics

Customer Acquisition Cost (CAC)

What it measures: Cost to acquire one new customer

Benchmarks (highly channel-dependent):

Formula:

CAC = (Sales + Marketing costs) ÷ New customers acquired

Red flags:

• ❌ CAC rising while ARPU and retention are flat
• ❌ CAC rising over time
• ❌ CAC > LTV × 0.33

Improvement levers:

• Focus on community-led growth
• Implement product-led growth
• Optimize onboarding conversion
• Build SEO/content for organic traffic

Customer Lifetime Value (LTV)

What it measures: Total revenue from average customer

Formula:

LTV = (ARPU × Gross Margin %) ÷ Monthly churn rate

Benchmarks (LTV:CAC ratio, directional):

Red flags:

• ❌ LTV:CAC persistently below ~3:1
• ❌ LTV <$500
• ❌ LTV declining over time

Improvement levers:

• Reduce churn (biggest lever)
• Increase ARPU through pricing
• Improve onboarding
• Add expansion revenue

CAC Payback Period

What it measures: Months to recover acquisition cost

Benchmarks (stage-dependent):

Retention Metrics

Monthly Churn Rate

What it measures: Percentage of customers canceling each month

Benchmarks (segment-sensitive):

Formula:

Monthly Churn = (Customers lost ÷ Total customers) × 100

Red flags:

• ❌ Monthly churn >5%
• ❌ Churn increasing over time
• ❌ Early customers churning fast

Improvement tactics:

• Improve onboarding and shorten time-to-value
• Implement customer success
• Build in-product stickiness
• Exit surveys to identify causes

Net Revenue Retention (NRR)

What it measures: Revenue retention including expansion

Formula:

NRR = ((Starting MRR + Expansion - Churn - Downgrades) ÷ Starting MRR) × 100

Benchmarks (directional):

Red flags:

• ❌ NRR <100%
• ❌ NRR declining

Improvement tactics:

• Implement expansion strategies
• Use tiered pricing to encourage upgrades
• Build usage-based pricing
• Proactive customer success

Common Mistakes

Mistake 1: Ignoring Churn

• Problem: Churn compounds - 5% monthly = 46% annually
• Solution: Measure weekly, then improve onboarding, fit, and lifecycle engagement before pushing harder on acquisition

Mistake 2: Vanity Metrics

• Problem: Tracking signups instead of revenue metrics
• Solution: Focus on MRR, churn, LTV:CAC

Mistake 3: Outdated Benchmarks

• Problem: Using generic benchmarks without segment context
• Solution: Compare against peers by model, stage, and ACV; many teams use 3:1-5:1 as a working LTV:CAC band

Mistake 4: Measuring Infrequently

• Problem: Quarterly reviews miss trends
• Solution: Weekly metrics review, monthly deep analysis

Next Steps

After running your metrics checkup:

1. Address red flags first - Focus on critical metrics
2. Use related skills - Deep-dive into problem areas
3. Track monthly - Re-run this analysis every month
4. Celebrate strengths - Don't fix what isn't broken
