SaaS Financial Metrics Quick Reference (finance-metrics-quickref)

Skill Overview

finance-metrics-quickref is a SaaS financial metrics cheat sheet for product managers and founders. It covers the formulas, healthy benchmarks, and red flags for 31 commonly used metrics, helping you find the numbers needed for decision-making within 5–10 minutes without having to read lengthy tutorials.

Use Cases

1. Quickly looking up metrics during product or financial reviews: When you need to confirm the NRR formula, a healthy LTV:CAC level, or the standard CAC payback period, go directly to the relevant row to find the formula and benchmark and continue the discussion.
2. Refreshing decision rules before board or investor meetings: Check key metric thresholds based on the company’s stage (early-stage, growth-stage, or scaling). For example, growth-stage companies should focus on NRR > 100%, Rule of 40 > 40, and Magic Number > 0.75.
3. Evaluating feature investments, customer acquisition channels, or pricing changes: Before making specific decisions such as “Should we build this feature?”, “Should we increase spending on this channel?”, or “Can we raise prices?”, quickly verify the metrics required by the relevant framework before reaching a conclusion.

Core Features

1. Comprehensive metrics reference table: Covers 31 metrics across four categories—revenue growth, unit economics, capital efficiency, and efficiency ratios. Each metric includes its formula, what it measures, healthy benchmarks, and red flags. From Revenue, ARPU, and MRR/ARR to Burn Rate, Runway, and Operating Leverage, everything is available in one table.
2. Four rapid decision-making frameworks: Includes four decision flows for “whether to build a feature,” “whether to expand a customer acquisition channel,” “whether to adjust pricing,” and “whether the business is healthy.” Each lists the required metrics and pass/reject criteria. For example, before expanding a channel, both LTV:CAC > 3:1 and a payback period < 18 months must be met.
3. Categorized red-flag checklist: Organizes warning signals and recommended actions into three categories: revenue and growth, unit economics, and capital efficiency. For example, NRR < 100% indicates that the existing customer base is contracting, a payback period > 24 months is a cash trap, and an operating runway < 6 months requires immediate action.

Frequently Asked Questions

What is the formula for NRR? What is considered healthy?

NRR (Net Revenue Retention) = (Beginning ARR + Expansion - Churn - Contraction) / Beginning ARR × 100%. Benchmarks: above 120% is excellent, 100%–120% is good, and 90%–100% is marginally acceptable. Below 100% indicates that existing revenue is shrinking; you should address expansion or churn issues before increasing customer acquisition spending.

How does this cheat sheet differ from in-depth educational skills?

finance-metrics-quickref is positioned as a cheat sheet designed for speed: it provides formulas, benchmarks, and decision rules without detailed derivations or examples. If you are learning these metrics for the first time or need complete calculation procedures and an analysis of common pitfalls, use an in-depth educational skill instead, such as saas-revenue-growth-metrics or saas-economics-efficiency-metrics. This skill is best suited for users who already understand the concepts and only need to verify them quickly.

What LTV:CAC ratio is considered healthy?

3:1 is the healthy benchmark. Below 1.5:1 indicates that you are buying revenue at a loss; reduce CAC or increase LTV before scaling. Above 5:1 may indicate underinvestment and overly conservative growth. Note that you should not look at the ratio alone: even if LTV:CAC meets the benchmark, a payback period exceeding 24 months or a Quick Ratio below 2 likewise indicates problems with unit economics.
