# 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 le
