## The short definition

Hold that thought.Impairment Charge is a unit-economics concept. Fix what it covers before the team debates tactics, and the rest of the conversation gets easier.

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

## How operators apply it

Start here.There is no single setting for Impairment Charge. It bends to the audience, the channels, and the wider plan.

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

Keep the order simple: define Impairment Charge for your context, then decide how to act. Reverse it and the budget chases a number nobody agreed on. Read that twice.

## When teams use it

Worth a slow read.Bring Impairment Charge in when a live call depends on it. With no decision on the table, it stays background.

Bring Impairment Charge in when a live choice hangs on it. In finance & unit economics work, that usually means one of three moments. Away from a decision, Impairment Charge is background, not a lever.

2. **Choosing a metric.** Impairment Charge flags whether the number you report is causal.
3. **Comparing options.** Impairment Charge corrects two options that look alike but are not.
