Purpose

Master revenue and retention metrics to understand SaaS business momentum, evaluate product-market fit, and make data-driven decisions about growth investments. Use this to calculate key metrics, interpret trends, identify problems early, and communicate business health to stakeholders.

This is not a business intelligence tool—it's a framework for PMs to understand which metrics matter, how to calculate them correctly, and what actions to take based on the numbers.

Input

**Works best with:** The question you're answering (is growth healthy? is churn a fire?) or the metrics you want interpreted. **Also useful:** Your numbers — MRR/ARR, growth rate, GRR/NRR, expansion, cohort data — partial data is workable.

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.** Use it as a reference: read the metric sections relevant to your diagnosis.

**Example invocation:** `Interpret these: $4M ARR, 8% MoM growth, GRR 88%, NRR 103% — is the growth masking a churn problem?`

Key Concepts

Revenue Metrics Family

The "top-line" metrics that measure how much money the business generates.

**Revenue** — Total money earned from selling products/services before expenses. The "top line" of the income statement.

• **Why PMs care:** Every feature should connect to revenue (direct or indirect). If you can't articulate revenue impact, prioritization becomes impossible.
• **Formula:** Sum of all customer payments in a period
• **Benchmark:** Growth rate matters more than absolute number (context-dependent by stage)

**ARPU (Average Revenue Per User)** — Average revenue generated per individual user.

• **Why PMs care:** Measures per-seat monetization effectiveness. Critical for seat-based pricing models.
• **Formula:** `Total Revenue / Total Users`
• **Benchmark:** Varies by model; track trend more than absolute value
• **B2C SaaS:** $5-50/month typical; B2B: $50-500+/month

**ARPA (Average Revenue Per Account)** — Average revenue generated per customer account.

• **Why PMs care:** Measures account-level deal size. Critical for account-based pricing models.
• **Formula:** `MRR / Active Accounts`
• **Benchmark:** SMB SaaS: $100-$1K/month; Mid-market: $1K-$10K; Enterprise: $10K+

**ARPA/ARPU Analysis** — Using both metrics together to understand monetization.

• **Why PMs care:** Prevents packaging mistakes. High ARPA + low ARPU = undermonetized per seat. Low ARPA + high ARPU = small deal sizes.
• **Example:** $10K ARPA with 100 seats = $100 ARPU (reasonable). $10K ARPA with 1,000 seats = $10 ARPU (leaving money on table).

**ACV (Annual Contract Value)** — Annualized recurring revenue per contract (excludes one-time fees).

• **Why PMs care:** Compares economics across different contract structures. Enables sales compensation design and segment analysis.
• **Formula:** `Annual Recurring Revenue per Contract` (don't include setup fees, professional services)
• **Benchmark:** SMB: $5K-$25K; Mid-market: $25K-$100K; Enterprise: $100K+

**MRR/ARR (Monthly/Annual Recurring Revenue)** — Predictable recurring revenue normalized to monthly or annual.

• **Why PMs care:** The heartbeat of subscription businesses. Valued at 5-10x+ multiples. Track components (new, expansion, churn).
• **Formula:** `MRR = Sum of all recurring subscription revenue per month`; `ARR = MRR × 12`
• **Benchmark:** Growth rate and quality matter; track new MRR, expansion MRR, churned MRR, contracted MRR

**Gross vs. Net Revenue** — Gross revenue before vs. net revenue after discounts, refunds, credits.

• **Why PMs care:** Discounts and refunds can hide bad acquisition quality or product problems.
• **Formula:** `Net Revenue = Gross Revenue - Discounts - Refunds - Credits`
• **Benchmark:** Refunds >10% is a red flag; track by acquisition channel

Retention & Expansion Metrics Family

Metrics that measure how well you keep and grow existing customers.

**Churn Rate** — Percentage of customers who cancel in a period.

• **Why PMs care:** Silent killer of SaaS. Undermines all acquisition efforts. 5% monthly churn = 46% annual churn (compounding).
• **Formula:** `Customers Lost in Period / Starting Customers`
• **Benchmark (Monthly):** <2% great, 2-5% acceptable, >5% crisis
• **Benchmark (Annual):** <10% great, 10-30% acceptable, >30% crisis
• **Note:** Logo churn (customer count) differs from revenue churn (dollar amount)

**NRR (Net Revenue Retention)** — Revenue retention from existing customers including expansion and contraction.

• **Why PMs care:** The holy grail metric. NRR >100% means you grow without new logos. Highly valued by investors.
• **Formula:** `(Starting ARR + Expansion - Churn - Contraction) / Starting ARR × 100`
• **Benchmark:** >120% excellent, 100-120% good, 90-100% acceptable, <90% problem
• **Example:** Start with $1M ARR, add $300K expansion,
