What You'll Walk Away Able to Do

Correctly Read an LTV:CAC Ratio

know when a great-looking number actually signals under-investment.

Catch a Vanity Revenue Metric Before It Misleads You

spot when ARPU or MRR growth is hiding a real problem.

Sound Sharp Talking Payback Period with Leadership

know it depends on cash position, not a universal rule.

Know Exactly How to Separate Blended CAC from Paid CAC

in revenue conversations, not just acquisition ones.

8 Metrics. Every Revenue Follow-Up Question Covered.

01

ARPU (Average Revenue Per User)

one blended number that can flatten a business built on very different kinds of users.

02

LTV (Lifetime Value)

a prediction about the future, not a fact about the present.

03

LTV:CAC Ratio

the single ratio that decides whether your growth engine actually makes money.

04

MRR / ARR

the predictable heartbeat of a subscription business.

05

Payback Period

how long the business fronts the cost before a customer starts paying it back.

06

Net Revenue Retention

a business can grow revenue from existing customers even while losing some of them.

07

Expansion Revenue Rate

growing an account you already have is often cheaper than winning a new one.

08

Gross Margin

revenue tells you what came in, gross margin tells you what's actually left.

Why This Actually Works

Not another glossary. A system for how to think.

Every metric ends with 3 real interview questions, a weak answer next to a strong one, and why the strong one works.

Question

Our LTV:CAC ratio is 4:1. Should we be pouring more money into growth?

Weak answer

Yes, a 4:1 ratio means we should scale spend as much as possible.

Strong answer

A strong ratio supports scaling, but I'd also check payback period and cash flow constraints, since a great long-term ratio can still strain the business if it takes too long to recover cost upfront, even if the eventual return is strong.
