- Current MRR: What is your current monthly recurring revenue?
- Customer count: How many paying customers? Average contract value?
- Pricing model: Per-seat, usage-based, flat-rate, tiered, or hybrid?
- Sales motion: Self-serve, sales-assisted, enterprise, or PLG?
- Churn concern: Are you seeing elevated churn? In which segment?

- Goal: What specific metric or question are you trying to answer?
Core SaaS Metrics Reference
Revenue Metrics
MRR (Monthly Recurring Revenue)
================================
MRR = Sum of all active subscription revenue normalized to monthly
MRR Components:
New MRR: Revenue from new customers this month
Expansion MRR: Revenue increase from existing customers (upgrades, add-ons)
Contraction MRR: Revenue decrease from existing customers (downgrades)
Churned MRR: Revenue lost from cancelled customers
Reactivation MRR: Revenue from returning customers
NET NEW MRR = New + Expansion + Reactivation - Contraction - Churned
ARR (Annual Recurring Revenue) = MRR x 12
Note: Only use ARR if most contracts are annual. Otherwise MRR is cleaner.
Churn Metrics
CHURN FORMULAS
==============
Logo Churn Rate (monthly):
= Customers lost in period / Customers at start of period x 100
Revenue Churn Rate (monthly, gross):
= Churned MRR / MRR at start of period x 100
Net Revenue Retention (NRR):
= (Starting MRR - Contraction - Churned + Expansion) / Starting MRR x 100
NRR > 100% --> Expansion outpaces churn (excellent)
NRR 90-100% --> Healthy but limited expansion
NRR < 90% --> Leaky bucket, fix retention before scaling acquisition
QUICK CHURN DIAGNOSTIC:
Monthly churn 2% --> ~22% annual churn (concerning for SMB, critical for enterprise)
Monthly churn 5% --> ~46% annual churn (unsustainable at any scale)
Monthly churn 8%+ --> ~63% annual churn (existential threat)
Annual churn conversion: 1 - (1 - monthly_rate)^12
Customer Lifetime Value
LTV CALCULATIONS
================
Simple LTV:
LTV = ARPU / Monthly Churn Rate
Gross-margin adjusted LTV:
LTV = (ARPU x Gross Margin %) / Monthly Churn Rate
Example:
ARPU = $200/month
Monthly churn = 3%
Gross margin = 80%
Simple LTV = $200 / 0.03 = $6,667
GM-adjusted LTV = ($200 x 0.80) / 0.03 = $5,333
LTV:CAC RATIO:
< 1:1 --> Losing money on every customer (unsustainable)
1:1-3:1 --> Unhealthy, improve retention or reduce CAC
3:1 --> Healthy benchmark target
5:1+ --> Strong, consider investing more in acquisition
> 8:1 --> May be under-investing in growth
Customer Acquisition Cost
CAC CALCULATION
===============
Fully Loaded CAC:
= (Sales + Marketing spend in period) / New customers acquired in period
Include:
- Salaries and commissions (sales, marketing, SDR teams)
- Advertising and content spend
- Tools and software for sales/marketing
- Event and sponsorship costs
Blended vs. Segmented:
Always calculate CAC per segment (self-serve vs. enterprise)
Blended CAC hides problems in individual channels
CAC PAYBACK PERIOD:
= CAC / (ARPU x Gross Margin %)
< 12 months --> Excellent (especially for SMB)
12-18 months --> Healthy
18-24 months --> Acceptable for enterprise
> 24 months --> Cash flow risk, needs attention
Cohort Analysis Framework
Revenue Cohort Template
MONTHLY REVENUE RETENTION BY COHORT
====================================
Cohort M0 M1 M2 M3 M6 M12 M18 M24
Jan-24 100% 92% 87% 84% 78% 68% 62% 58%
Feb-24 100% 94% 90% 87% 82% 73% -- --
Mar-24 100% 93% 88% 85% 80% -- -- --
Apr-24 100% 95% 91% 89% -- -- -- --
Reading this table:
- Each row is a group of customers who started in that month
- Percentages show how much of original MRR remains at each interval
- Look for: improving cohorts over time (product/onboarding improvements working)
- Red flag: accelerating drop-off at M3-M6 (engagement cliff)
What to Look For in Cohorts
- Early churn spike: If >15% churns in month 1, onboarding is broken
- Cohort improvement: Newer cohorts retaining better = product improvements working
- Expansion inflection: When does expansion revenue start kicking in?
- Segment differences: Enterprise vs SMB cohorts behave very differently
- Seasonal patterns: Do Q4 cohorts churn faster in Q1? (Budget resets)

Diagnostic Frameworks
The Leaky Bucket Diagnostic
When MRR growth stalls despite acquiring customers:
STEP 1: Calculate net new MRR components
New MRR: $______
Expansion MRR: $______
Contraction MRR: $______ (is this > 10% of expansion?)
Churned MRR: $______ (is this > new MRR?)
STEP 2: Identify the leak
If churned > new: Acquisition cannot outrun churn -- fix retention first
If contraction is high: Downgrades signal poor value delivery at higher tiers
If expansion is zero: No upsell path -- pricing or packaging problem
If new is declining: Market fit, positioning, or channel saturation issue
STEP 3: Segment the churn
By plan/tier: Which tier churns most?
By tenure: When do customers leave? (Month 1-3? Month 12?)
By acquisition: Which channel produces churners?
By use case: Which customer profile retains best?
Growth Ceiling Diagnostic
GROWTH BOTTLENECK IDENTIFIER
==============================
Symptom Likely Bottleneck
------- -----------------
High trial signups, low convert Activation / onboarding
Good activation, high M1 churn Value delivery / expectations mismatch
Strong M1, cliff at M6-M12 Engagement depth / habit formation
Low expansion revenue Pricing ceiling / no upsell triggers
High CAC, declining efficiency Channel saturation / audience exhaustion
Good metrics but slow MRR growth Market size constraint / niche ceiling

Quick Formulas Reference Card
FORMULA QUICK REFERENCE
========================
MRR Growth Rate = (MRR_end - MRR_start) / MRR_start x 100
Months to Double = 72 / (MoM Growth Rate x 12) [Rule of 72 approx]
ARPU = MRR / Total Customers
Quick Ratio = (New MRR + Expansion MRR) / (Churned MRR + Contraction MRR)
> 4 is excellent, < 1 means shrinking
Magic Number = Net New ARR / Prior Quarter S&M Spend
> 0.75 means efficient growth, > 1.0 is excellent
Gross Margin = (Revenue - COGS) / Revenue x 100
COGS for SaaS: hosting, support, onboarding, third-party APIs
Revenue per Employee = ARR / Total Employees
Benchmark: $100K-$300K for growth, $300K+ for efficient
