Saas Economics Efficiency Metrics

This is the SaaS financial health checkup you run before making big bets. It walks you through the metrics that actually matter: CAC, LTV, payback periods, burn rate, and Rule of 40. The intent is clear: figure out if your business model can scale or if you need to fix unit economics first. Use it when prepping board decks, deciding whether to pour money into paid acquisition, or explaining to leadership why growth needs to slow down while you optimize margin. It covers the full efficiency stack, not just vanity metrics. Honest take: if you're a PM at a SaaS company and these concepts feel fuzzy, this will get you fluent fast.

Purpose

Determine whether your SaaS business model is fundamentally viable and capital-efficient. Use this to calculate unit economics, assess profitability, manage cash runway, and decide when to scale vs. optimize. Essential for fundraising, board reporting, and making smart investment trade-offs.

This is not a finance reporting tool—it's a framework for PMs to understand whether the business can sustain growth, when to prioritize efficiency over growth, and which investments have positive returns.

Input

Works best with: The question you're answering (can we scale? raise? extend runway?) or the metrics you want evaluated. Also useful: Your numbers — CAC, gross margin, burn, runway, magic number — 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 stage and decision.
