unit economics
The direct revenues and costs associated with a particular business model expressed on a per-unit basis, typically analyzed as the ratio of LTV to CAC.
Example
“The startup's unit economics showed a 5:1 LTV to CAC ratio — healthy enough to justify aggressive growth spending.”
Memory Tip
UNIT ECONOMICS = does one customer make you money? LTV:CAC ratio of 3:1+ is healthy.
Why It Matters
Unit economics helps you understand whether a business or service is actually profitable at its core level. By comparing what you spend to acquire a customer against what they generate in lifetime value, you can evaluate if a business model is sustainable and worth your investment or patronage.
Common Misconception
Many people assume that if a company is growing rapidly, its unit economics must be healthy. However, a business can grow quickly while losing money on each customer, which means it is unsustainable and will eventually fail without fixing its fundamental costs or revenue model.
In Practice
Consider a subscription service where it costs $50 to acquire a customer through advertising, but the average customer pays $15 per month for 8 months before canceling, generating $120 in lifetime value. The LTV to CAC ratio would be 2.4 to 1, indicating the business makes $2.40 for every dollar spent acquiring customers, which is generally considered healthy and sustainable.
Etymology
UNIT (single instance, one customer) ECONOMICS (financial analysis). The ECONOMICS of a single UNIT (customer).
