Understand LTV:CAC ratio
One idea, three depths
Choose how deeply to explain LTV:CAC ratio
LTV:CAC ratio: Compare estimated customer lifetime value with acquisition cost.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using LTV:CAC ratio to answer this question: compare estimated customer lifetime value with acquisition cost? Enter Estimated customer lifetime value and Customer acquisition cost; the calculator shows LTV to CAC ratio. Try changing one number and watch what happens to LTV to CAC ratio. The answer tells you LTV to CAC ratio.
Age 15Explain it to a 15-year-oldConnect it to the formula
The ratio is useful only when LTV and CAC use compatible cohorts, margins, time horizons and fully loaded acquisition costs. The rule is LTV:CAC ratio = customer lifetime value ÷ customer acquisition cost. Its input values are Estimated customer lifetime value, Customer acquisition cost, and the main result is LTV to CAC ratio. Try changing one number and watch what happens to LTV to CAC ratio.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is LTV:CAC ratio = customer lifetime value ÷ customer acquisition cost, evaluated from Estimated customer lifetime value, Customer acquisition cost to produce LTV to CAC ratio. The ratio is useful only when LTV and CAC use compatible cohorts, margins, time horizons and fully loaded acquisition costs. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Compare estimated customer lifetime value with acquisition cost.
Why the business model works
The ratio is useful only when LTV and CAC use compatible cohorts, margins, time horizons and fully loaded acquisition costs.
Inputs and operating assumptions
This model uses Estimated customer lifetime value (at least 0), Customer acquisition cost (at least 0.01). Keep currencies, accounting treatment and time periods consistent with one another.
The formula
LTV:CAC ratio = customer lifetime value ÷ customer acquisition cost
What the calculator produces
The primary output is LTV to CAC ratio; it also exposes Lifetime value after acquisition cost, Acquisition cost share of LTV. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
