# Startup Metrics Framework

Comprehensive guide to tracking, calculating, and optimizing key performance metrics for different startup business models from seed through Series A.

## Overview

Track the right metrics at the right stage. Focus on unit economics, growth efficiency, and cash management metrics that matter for fundraising and operational excellence.

## Universal Startup Metrics

### Revenue Metrics

**MRR (Monthly Recurring Revenue)**
```
MRR = Σ (Active Subscriptions × Monthly Price)
```

**ARR (Annual Recurring Revenue)**
```
ARR = MRR × 12
```

**Growth Rate**
```
MoM Growth = (This Month MRR - Last Month MRR) / Last Month MRR
YoY Growth = (This Year ARR - Last Year ARR) / Last Year ARR
```

**Target Benchmarks:**
- Seed stage: 15-20% MoM growth
- Series A: 10-15% MoM growth, 3-5x YoY
- Series B+: 100%+ YoY (Rule of 40)

### Unit Economics

**CAC (Customer Acquisition Cost)**
```
CAC = Total S&M Spend / New Customers Acquired
```

Include: Sales salaries, marketing spend, tools, overhead

**LTV (Lifetime Value)**
```
LTV = ARPU × Gross Margin% × (1 / Churn Rate)
```

Simplified:
```
LTV = ARPU × Average Customer Lifetime × Gross Margin%
```

**LTV:CAC Ratio**
```
LTV:CAC = LTV / CAC
```

**Benchmarks:**
- LTV:CAC > 3.0 = Healthy
- LTV:CAC 1.0-3.0 = Needs improvement
- LTV:CAC < 1.0 = Unsustainable

**CAC Payback Period**
```
CAC Payback = CAC / (ARPU × Gross Margin%)
```

**Benchmarks:**
- < 12 months = Excellent
- 12-18 months = Good
- > 24 months = Concerning

### Cash Efficiency Metrics

**Burn Rate**
```
Monthly Burn = Monthly Revenue - Monthly Expenses
```

Negative burn = losing money (typical early-stage)

**Runway**
```
Runway (months) = Cash Balance / Monthly Burn Rate
```

**Target:** Always maintain 12-18 months runway

**Burn Multiple**
```
Burn Multiple = Net Burn / Net New ARR
```

**Benchmarks:**
- < 1.0 = Exceptional efficiency
- 1.0-1.5 = Good
- 1.5-2.0 = Acceptable
- > 2.0 = Inefficient

Lower is better (spending less to generate ARR)

## SaaS Metrics

### Revenue Composition

**New MRR**
New customers × ARPU

**Expansion MRR**
Upsells and cross-sells from existing customers

**Contraction MRR**
Downgrades from existing customers

**Churned MRR**
Lost customers

**Net New MRR Formula:**
```
Net New MRR = New MRR + Expansion MRR - Contraction MRR - Churned MRR
```

### Retention Metrics

**Logo Retention**
```
Logo Retention = (Customers End - New Customers) / Customers Start
```

**Dollar Retention (NDR - Net Dollar Retention)**
```
NDR = (ARR Start + Expansion - Contraction - Churn) / ARR Start
```

**Benchmarks:**
- NDR > 120% = Best-in-class
- NDR 100-120% = Good
- NDR < 100% = Needs work

**Gross Retention**
```
Gross Retention = (ARR Start - Churn - Contraction) / ARR Start
```

**Benchmarks:**
- > 90% = Excellent
- 85-90% = Good
- < 85% = Concerning

### SaaS-Specific Metrics

**Magic Number**
```
Magic Number = Net New ARR (quarter) / S&M Spend (prior quarter)
```

**Benchmarks:**
- > 0.75 = Efficient, ready to scale
- 0.5-0.75 = Moderate efficiency
- < 0.5 = Inefficient, don't scale yet

**Rule of 40**
```
Rule of 40 = Revenue Growth Rate% + Profit Margin%
```

**Benchmarks:**
- > 40% = Excellent
- 20-40% = Acceptable
- < 20% = Needs improvement

**Example:**
50% growth + (10%) margin = 40% ✓

**Quick Ratio**
```
Quick Ratio = (New MRR + Expansion MRR) / (Churned MRR + Contraction MRR)
```

**Benchmarks:**
- > 4.0 = Healthy growth
- 2.0-4.0 = Moderate
- < 2.0 = Churn problem

## Marketplace Metrics

### GMV (Gross Merchandise Value)

**Total Transaction Volume:**
```
GMV = Σ (Transaction Value)
```

**Growth Rate:**
```
GMV Growth Rate = (Current Period GMV - Prior Period GMV) / Prior Period GMV
```

**Target:** 20%+ MoM early-stage

### Take Rate

```
Take Rate = Net Revenue / GMV
```

**Typical Ranges:**
- Payment processors: 2-3%
- E-commerce marketplaces: 10-20%
- Service marketplaces: 15-25%
- High-value B2B: 5-15%

### Marketplace Liquidity

**Time to Transaction**
How long from listing to sale/match?

**Fill Rate**
% of requests that result in transaction
