The short definition

Start here.Dilution is a unit-economics concept. Fix what it covers before the team debates tactics, and the rest of the conversation gets easier.

Reduction in existing shareholders' ownership percentage from new share issuance.

This is a financial concept that affects how operators measure efficiency, value, or return. It typically appears in models, board reports, and management decisions about resource allocation. Misapplying or miscalculating it leads to bad decisions.

Dilution sits in Finance & Unit Economics; it is a unit-economics concept. Define it once and the reporting holds together.

How it works

One idea, plainly put.Dilution is no fixed dial. How it behaves depends on your audience, your channel mix, and the strategy around it.

Dilution behaves unlike a fixed rule. An early-stage brand and a mature one will apply Dilution on different terms. The mechanics follow the inputs around it. Treat Dilution as a buzzword and the reporting misleads; agree on it and the numbers hold.

Keep the order simple: define Dilution for your context, then decide how to act. Reverse it and the budget chases a number nobody agreed on. Keep this in mind.

When teams use it

Read that twice.Bring Dilution in when a live call depends on it. With no decision on the table, it stays background.

Dilution matters at the point of a decision. In finance & unit economics, three moments come up again and again. Outside them, Dilution is reference material.

Setting budget. Dilution marks where added spend will work hardest.
Choosing a metric. Dilution checks that the figure is not just noise.
Comparing options. Dilution corrects two options that look alike but are not.

A worked example

Pick one definition.The example below traces Dilution through a real Calm scenario, with real limits and a number to read at the end.

Take Calm. During an LTV recut by cohort, the team made Dilution the deciding input, not an afterthought. They set a baseline first, agreed one definition of Dilution, and only then read the result: the annual plan paid back 2.6x faster. The number matters less than the order.

Worked example for Dilution -- illustrative figures, RGM analysis
Stage	What the team did	The reason
Baseline	Read the starting point before any change to Dilution.	A reference to judge against.
Define	Locked the scope of Dilution so it stayed stable.	Two people, one meaning.
Act	An LTV recut by cohort — one variable.	Cause and effect, isolated.
Result	The annual plan paid back 2.6x faster	A call backed by the read.

These Dilution numbers are illustrative -- RGM analysis. The structure travels; the specific figures do not.

Common mistakes

Look at it this way.Four failure modes recur with Dilution. Name them and they are easy to design around.

One-size thinking. Using Dilution flat across every segment. The right cut differs by channel and margin.
No context. Reporting Dilution with no baseline. A bare number cannot be judged.
Wrong target. Treating Dilution as the goal. The goal is the outcome it predicts.
Bad compares. Benchmarking Dilution with no adjustment. Account for the model differences first.
