## Purpose

Quick reference for any SaaS finance metric without deep teaching. Use this when you need a fast formula lookup, benchmark check, or decision framework reminder. For detailed explanations, calculations, and examples, see the related deep-dive skills.

This is not a teaching tool—it's a cheat sheet optimized for speed. Scan, find, apply.

## Input

**Works best with:** The metric you need — name it and get the formula, benchmark, and decision context.
**Also useful:** Your numbers, if you want the formula applied on the spot.

Anything supplied with the invocation itself — text after the skill name, a pasted context dump, or an appended `ARGUMENTS:` line — counts as answers already given. Use it and skip whatever it covers; don't re-ask.

**Arriving empty-handed? That works too.** Ask for the metric family you're working in (revenue, retention, efficiency, capital) and scan from there.

**Example invocation:** `Quick ref: burn multiple — formula, benchmark, and whether 1.7 is bad for Series B.`

## Key Concepts

### Metric Categories

Metrics are organized into four families:

1. **Revenue & Growth** — Top-line money (revenue, ARPU, ARPA, MRR/ARR, churn, NRR, expansion)
2. **Unit Economics** — Customer-level profitability (CAC, LTV, payback, margins)
3. **Capital Efficiency** — Cash management (burn rate, runway, OpEx, net income)
4. **Efficiency Ratios** — Growth vs. profitability balance (Rule of 40, magic number)

### When to Use This Skill

**Use this when:**
- You need a quick formula or benchmark
- You're preparing for a board meeting or investor call
- You're evaluating a decision and need to check which metrics matter
- You want to identify red flags quickly

**Don't use this when:**
- You need detailed calculation guidance (use `saas-revenue-growth-metrics` or `saas-economics-efficiency-metrics`)
- You're learning these metrics for the first time (start with deep-dive skills)
- You need examples and common pitfalls (covered in related skills)

## Application

### All Metrics Reference Table

| **Metric** | **Formula** | **What It Measures** | **Good Benchmark** | **Red Flag** |
|------------|-------------|----------------------|-------------------|--------------|
| **Revenue** | Total sales before expenses | Top-line money earned | Growth rate >20% YoY (varies by stage) | Revenue growing slower than costs |
| **ARPU** | Total Revenue / Total Users | Revenue per individual user | Varies by model; track trend | ARPU declining cohort-over-cohort |
| **ARPA** | MRR / Active Accounts | Revenue per customer account | SMB: $100-$1K; Mid: $1K-$10K; Ent: $10K+ | High ARPA + low ARPU (undermonetized seats) |
| **ACV** | Annual Recurring Revenue per Contract | Annualized contract value | SMB: $5K-$25K; Mid: $25K-$100K; Ent: $100K+ | ACV declining (moving downmarket unintentionally) |
| **MRR/ARR** | MRR × 12 = ARR | Predictable recurring revenue | Growth + quality matter; track components | New MRR declining while churn stable/growing |
| **Churn Rate** | Customers Lo
