Phase 1: Metrics Architecture

Step 1 — Identify Your Model & Stage

Before tracking anything, classify yourself:

Business Model:

model_type:
  saas:
    sub_type: # self-serve | sales-led | PLG | hybrid
    pricing: # per-seat | usage-based | flat | tiered
    contract: # monthly | annual | multi-year
  marketplace:
    type: # managed | unmanaged | SaaS-enabled
    unit: # GMV | take-rate | transaction
  consumer:
    type: # subscription | ad-supported | freemium | transactional
    engagement_model: # DAU/MAU | session-based | content
  hardware_plus_software:
    type: # device + subscription | IoT | embedded

Stage (determines what matters):

Stage	ARR Range	North Star Focus	Board Cares About
Pre-seed	$0-$50K	Engagement + retention signal	Problem-solution fit evidence
Seed	$50K-$500K	Cohort retention + early revenue	Product-market fit signals
Series A	$500K-$3M	Growth efficiency + unit economics	LTV:CAC, NDR, growth rate
Series B	$3M-$15M	Scalability + operating leverage	Rule of 40, magic number, burn multiple
Growth	$15M+	Capital efficiency + market share	Net margins, NRR, competitive moat

Step 2 — Build Your Metric Stack

Layer 1: Health Vitals (track daily)

- Revenue: MRR, ARR, net new MRR
- Growth: MoM growth rate, WoW for early stage
- Retention: Logo churn rate, revenue churn rate
- Cash: Monthly burn, runway in months

Layer 2: Efficiency (track weekly)

- Unit economics: CAC, LTV, LTV:CAC ratio, payback months
- Sales: Pipeline coverage, win rate, sales cycle length
- Product: Activation rate, feature adoption, NPS/CSAT
- Team: Revenue per employee, quota attainment

Layer 3: Strategic (track monthly)

- NDR (Net Dollar Retention)
- Burn multiple
- Rule of 40 score
- Magic number
- Cohort analysis curves

Phase 2: The Complete Formula Reference

Revenue Metrics

MRR = Σ(active_subscriptions × monthly_price)
ARR = MRR × 12

Net New MRR = New MRR + Expansion MRR - Churned MRR - Contraction MRR

MRR Components:
  new_mrr:         First-time customer revenue this month
  expansion_mrr:   Upsell + cross-sell from existing customers
  churned_mrr:     Revenue lost from customers who left
  contraction_mrr: Revenue lost from downgrades (customer stayed)
  reactivation_mrr: Revenue from returning churned customers

MoM Growth = (MRR_current - MRR_previous) / MRR_previous
CMGR (Compound Monthly Growth Rate) = (MRR_end / MRR_start)^(1/months) - 1

Why CMGR > MoM: Monthly growth is noisy. CMGR smooths 6-12 month periods for real trend.

Unit Economics

CAC = Total_Sales_Marketing_Spend / New_Customers_Acquired
  - Include: salaries, commissions, tools, ads, events, content costs
  - Exclude: product/engineering, CS (post-sale)
  - Time-lag adjustment: match spend to cohort it generated (typically 1-3 month lag)

Blended CAC vs Channel CAC:
  blended_cac = total_spend / total_new_customers
  channel_cac = channel_spend / channel_new_customers
  # Always track both — blended hides channel problems

LTV = ARPU × Gross_Margin% × Average_Customer_Lifetime
  # Or: LTV = ARPU × Gross_Margin% × (1 / Monthly_Churn_Rate)
  # Cap at 5 years for conservative estimates

LTV:CAC Ratio — THE ratio:
  > 5.0  → Under-investing in growth (spend more!)
  3.0-5.0 → Excellent efficiency
  1.5-3.0 → Healthy but watch payback period
  1.0-1.5 → Marginal — fix churn or reduce CAC
  < 1.0  → Burning cash per customer — STOP and fix

CAC Payback = CAC / (Monthly_ARPU × Gross_Margin%)
  < 6 months  → Elite (PLG companies)
  6-12 months → Great
  12-18 months → Acceptable for enterprise
  > 18 months → Danger zone (unless >130% NDR)

Retention & Churn

Logo Churn Rate = Customers_Lost / Customers_Start_of_Period
Revenue Churn Rate = MRR_Lost / MRR_Start_of_Period
  # Revenue churn > logo churn = losing big customers (very bad)
  # Revenue churn < logo churn = losing small customers (less bad)

Net Dollar Retention (NDR) = (Starting_MRR + Expansion - Contraction - Churn) / Starting_MRR
  > 130% → World-class (Snowflake, Twilio territory)
  110-130% → Excellent
  100-110% → Good
  90-100% → Acceptable but concerning
  < 90% → Leaky bucket — growth can't outrun churn

Gross Dollar Retention (GDR) = (Starting_MRR - Contraction - Churn) / Starting_MRR
  # NDR without expansion — shows your floor
  > 90% → Sticky product
  80-90% → Normal for SMB
  < 80% → Product or market problem

Growth Efficiency

Burn Multiple = Net_Burn / Net_New_ARR
  < 1.0 → Amazing (rare at early stage)
  1.0-1.5 → Great
  1.5-2.0 → Good
  2.0-3.0 → Mediocre
  > 3.0 → Bad — inefficient growth

Rule of 40 = Revenue_Growth_Rate% + Profit_Margin%
  > 40 → Healthy SaaS (IPO-ready)
  # Example: 60% growth + -20% margin = 40 ✓
  # Example: 20% growth + 20% margin = 40 ✓

Magic Number = Net_New_ARR_This_Quarter / Sales_Marketing_Spend_Last_Quarter
  > 1.0 → Efficient, invest more in S&M
  0.5-1.0 → OK, optimize before scaling
  < 0.5 → Inefficient — fix before spending more

Hype Ratio = Valuation / ARR
  # Reality check on fundraising expectations
  # Median SaaS multiples: 6-12x ARR (varies by growth + retention)

Cash & Runway

Monthly Burn = Total_Monthly_Expenses - Total_Monthly_Revenue
Gross Burn = Total_Monthly_Expenses (ignoring revenue)
Net Burn = Gross_Burn - Revenue

Runway = Cash_Balance / Monthly_Net_Burn
  > 18 months → Comfortable
  12-18 months → Start planning next raise
  6-12 months → Urgently fundraising
  < 6 months → Default alive or dead calculation needed

Default Alive? = Can_Current_Growth_Rate_Make_Revenue > Expenses_Before_Cash_Runs_Out
  # Paul Graham's test — if growing, project the intersection

Sales Efficiency

Sales Cycle Length = Avg_Days(First_Touch → Closed_Won)
Pipeline Coverage = Total_Pipeline_Value / Revenue_Target
  # Need 3-4x for predictable revenue
  
Win Rate = Deals_Won / Total_Deals_in_Stage
  By stage: SQL→Opp (30-40%), Opp→Proposal (50-60%), Proposal→Close (60-70%)

ACV (Annual Contract Value) = Total_Contract_Value / Contract_Years
ASP (Average Selling Price) = Total_Revenue / Deals_Closed

Quota Attainment = Actual_Bookings / Quota_Target
  # Healthy org: 60-70% of reps hitting quota

Sales Efficiency = Net_New_ARR / Fully_Loaded_Sales_Cost
  > 1.0 → Scalable

Phase 3: Diagnostic Framework — PULSE Method

When a metric is off, don't just report it — diagnose it.

P — Pattern Recognition

Questions:
- Is this a trend (3+ months) or a blip (1 month)?
- Is it seasonal or structural?
- Did it change gradually or suddenly?
- Which cohorts/segments are affected?

U — Upstream Tracing

Every metric has upstream drivers. Trace back:

Revenue declining? →
  ├── New MRR down? → Lead volume? → Conversion rate? → Channel performance?
  ├── Expansion down? → Upsell attempts? → Product adoption? → CSM activity?
  └── Churn up? → Which segment? → Voluntary vs involuntary? → Reasons?

CAC increasing? →
  ├── Spend up? → Which channels? → CPM/CPC changes?
  ├── Volume same but cost up? → Market saturation? → Competition?
  └── Conversion down? → Funnel stage? → Lead quality? → Sales process?

L — Leverage Point

Find the highest-impact intervention:
- Which single metric, if improved 10%, would cascade the most?
- What's the cheapest/fastest fix vs highest-impact fix?
- Score: Impact (1-5) × Feasibility (1-5) × Speed (1-5)

S — So-What Translation

Convert metric into business language:
- "Churn increased 2%" → "We'll lose $X00K ARR this year at this rate"
- "CAC payback is 18 months" → "Each new customer is cash-negative for 1.5 years"
- "NDR is 95%" → "Even with zero new sales, we shrink 5% annually"

E — Experiment Design

diagnostic_experiment:
  hypothesis: "[Metric] is declining because [upstream cause]"
  test: "[Specific action] for [time period]"
  success_metric: "[Metric] improves by [X%] within [timeframe]"
  sample: "[Segment/cohort to test on]"
  kill_criteria: "Stop if [negative signal] within [days]"

---

Phase 4: Cohort Analysis — The Truth Machine

Aggregate metrics lie. Cohorts tell the truth.

Revenue Cohort Table

Track each monthly cohort's MRR over time:

         Month 0   Month 1   Month 3   Month 6   Month 12
Jan '25  $50K      $48K      $45K      $42K      $38K
Feb '25  $55K      $53K      $50K      $48K      —
Mar '25  $60K      $58K      $57K      $56K      —
Apr '25  $45K      $44K      $43K      —         —

Reading this:
- Jan cohort retained 76% at month 12 → mediocre
- Mar cohort retained 93% at month 3 → improving! What changed?
- Apr cohort started smaller but retention looks good

Engagement Cohort (Non-Revenue Signal)

cohort_engagement:
  week_1_activation: # % completing key action within 7 days
  week_4_habit: # % using product 3+ days in week 4
  month_3_retention: # % still active at 90 days
  
  # Leading indicators of revenue retention
  # If engagement drops, revenue follows 1-3 months later

Cohort Red Flags

🚩 Each new cohort retains worse → product-market fit eroding
🚩 Large cohorts churn more → scaling quality issues
🚩 Specific channel cohorts churn fast → bad-fit leads
🚩 Expansion only in old cohorts → pricing/packaging problem

Phase 6: Model-Specific Metrics

SaaS Additions

Quick Ratio = (New MRR + Expansion MRR) / (Churned MRR + Contraction MRR)
  > 4.0 → Very healthy growth
  2.0-4.0 → Good
  1.0-2.0 → Sustainable but slow
  < 1.0 → Shrinking

Logo-to-Revenue Retention Gap:
  If logo retention 85% but revenue retention 95% → upsell compensates
  If logo retention 85% and revenue retention 85% → no expansion = problem

Expansion Revenue % = Expansion MRR / Total New MRR
  > 30% → Healthy at scale
  # Best SaaS: expansion > new revenue (Twilio was 170% NDR)

Marketplace Additions

GMV (Gross Merchandise Value) = Total value of transactions on platform
Take Rate = Platform Revenue / GMV
  5-15% → Typical for most marketplaces
  15-30% → Managed/full-service marketplaces
  
Supply-side metrics:
  supply_liquidity = listings_with_transaction / total_listings
  time_to_first_match = avg_days_from_listing_to_sale
  
Demand-side metrics:
  search_to_fill = completed_transactions / searches
  repeat_purchase_rate = returning_buyers / total_buyers

Consumer/PLG Additions

DAU/MAU Ratio:
  > 50% → Exceptional (messaging apps)
  25-50% → Strong habit (social, productivity)
  10-25% → Good (media, entertainment)
  < 10% → Weak engagement

Viral Coefficient (K-factor) = Invites_per_User × Conversion_Rate
  > 1.0 → Viral growth (each user brings >1 new user)
  0.5-1.0 → Amplified growth
  < 0.5 → Not viral — need paid acquisition

Free-to-Paid Conversion:
  PLG benchmark: 2-5% of free users convert
  Freemium benchmark: 1-3%
  Enterprise self-serve: 5-15%

Time to Value = Time from signup to "aha moment"
  # Reduce this aggressively — strongest lever for activation

Phase 7: Metric Manipulation Red Flags

Vanity vs Real Metrics

Vanity (Avoid)	Real (Track)
Total signups	Activated users (completed key action)
Page views	Engaged sessions (>2 min or action taken)
"Pipeline"	Qualified pipeline (met ICP criteria)
Gross revenue	Net revenue (after refunds + credits)
Total customers	Active customers (logged in last 30d)
Downloads	WAU/MAU
"Partnerships"	Revenue from partnerships

Common Manipulation Tactics to Watch

🚩 Counting annual contracts as MRR at signing (vs. monthly recognition)
🚩 Excluding "one-time" churns from churn rate
🚩 Using gross revenue instead of net
🚩 Measuring CAC without fully-loaded costs
🚩 Cherry-picking best cohort as "representative"
🚩 Counting reactivations as new customers
🚩 Using "committed ARR" (signed but not live)
🚩 Trailing-12-month NDR when recent cohorts are worse

---

Phase 8: Action Playbooks

When CAC Is Too High

1. Audit channel efficiency — kill bottom 20% channels
2. Improve activation rate (reduces wasted spend)
3. Increase conversion at each funnel stage (+10% each = compound effect)
4. Shift mix: more organic/PLG, less paid
5. Reduce sales cycle length (lower cost per deal)
6. Tighten ICP — stop selling to bad-fit customers

When Churn Is Too High

1. Segment: which customers churn? (Size, channel, use case)
2. Time: when do they churn? (Month 1-3 = onboarding, 6-12 = value, 12+ = competition)
3. Reason: exit survey + CS interviews (top 3 reasons)
4. Fix activation if month 1-3 churn
5. Fix value delivery if month 6-12 churn
6. Fix switching cost / competitive moat if 12+ churn

When Growth Stalls

1. Check: is TAM exhausted in current segment? → Expand to adjacent
2. Check: conversion rates declining? → Product or message fatigue
3. Check: CAC rising with flat volume? → Channel saturation
4. Check: expansion revenue flat? → Packaging/pricing problem
5. Check: sales cycle lengthening? → Market conditions or competition

When Raising Capital

Metrics investors care about BY STAGE:

Pre-seed: Engagement, retention curves, market size
Seed: MoM growth (15%+), retention cohorts, early unit economics
Series A: $1M+ ARR, 3x+ YoY growth, LTV:CAC > 3, NDR > 100%
Series B: $5M+ ARR, path to Rule of 40, burn multiple < 2, sales efficiency

Edge Cases

Multi-Product Companies

Track metrics per product line AND blended. Watch for cross-subsidization where one product's margins mask another's losses.

Usage-Based Pricing

MRR is estimated, not contracted. Track committed vs consumed. Expansion is automatic (usage growth), so NDR is naturally higher — compare to usage-based peers, not seat-based.

Negative Churn via Price Increases

If NDR > 100% only because of price increases (not organic expansion), this is fragile. Separate price-driven vs usage-driven expansion.

Very Early Stage (Pre-Revenue)

Track leading indicators: activation rate, engagement frequency, NPS, waitlist growth, organic traffic, time-to-value. Revenue metrics come later — don't force them.

Seasonal Businesses

Use YoY comparisons, not MoM. Adjust cohort analysis for seasonal patterns. Build seasonal forecast models.
