## What the term covers

Here is the short version.Treat Equity Method as a unit-economics concept with a clear scope. Two people using the term should mean the same thing.

Accounting for 20-50% ownership

Equity Method belongs to Finance & Unit Economics and refers to a unit-economics concept. A shared definition keeps the team aligned.

## The mechanics

Keep this in mind.Equity Method works one way for a lean team and another for a large one. The mechanics follow the context.

Think of Equity Method as context-bound. A small shop reads it simply; an enterprise reads it with more nuance. That is normal -- Equity Method is shaped by audience and channel mix. Read Equity Method without care and the plan wobbles; be precise and the read holds.

The working rule is plain. Agree what Equity Method covers first, then act on it. Skip that order and Equity Method loses its shared meaning, and two teams end up measuring two different things. Start here.

## Where it shows up

Read that twice.Reach for Equity Method when a real decision rides on it -- a budget, a metric, or a comparison. Otherwise it is reference.

2. **Choosing a metric.** Equity Method flags whether the number you report is causal.
3. **Comparing options.** Equity Method keeps a head-to-head from fooling the reader.

## A worked example

Keep this in mind.Below, Equity Method is put inside a Dollar Shave Club setting -- real trade-offs, a clear baseline, and a figure to test it.

Look at Dollar Shave Club. In a CAC-payback tightening, Equity Method drove the decision rather than sitting in a footnote. A baseline came first, then a single agreed meaning of Equity Method, then the read: payback shortened from 14 to 9 months.
