## A working definition

Keep this in mind.Deductible is a capital concept. Fix what it covers before the team debates tactics, and the rest of the conversation gets easier.

First-loss amount before indemnification.

Within Capital & Investing, Deductible is a capital concept. Get the definition right and the work that follows gets easier.

## The mechanics

Here is the short version.Deductible produces value through how it is applied. Change the inputs and the right use of it changes too.

Deductible is not a switch you flip. It names a moving idea, and the way it plays out shifts with the setup. A lean team running one paid channel applies Deductible differently than a brand running ten. Use Deductible loosely and teams pull apart; pin it down and the math lines up.

One rule always holds. Settle the scope of Deductible up front, then build the plan. Get it backwards and Deductible becomes a word everyone uses and no one shares. Keep this in mind.

## When to reach for it

One idea, plainly put.Bring Deductible in when a live call depends on it. With no decision on the table, it stays background.

Bring Deductible in when a live choice hangs on it. In capital & investing work, that usually means one of three moments. Away from a decision, Deductible is background, not a lever.

1. **Setting budget.** Deductible points to where the next dollar should go.
2. **Choosing a metric.** Deductible checks that the figure is not just noise.
3. **Comparing options.** Deductible corrects two options that look alike but are not.

## Worked example

Here is the short version.The walk-through runs Deductible through work modeled on a Series B marketplace, so the concept meets real constraints.

Consider a Series B marketplace. Running a CAC-to-LTV review, the team put Deductible at the center of the call. With a clean baseline and one fixed definition of Deductible, they read what moved: runway extended after re-pricing a 3:1 segment. The discipline is the lesson.

Example walk-through for Deductible -- figures illustrative, RGM analysis

| Stage | The step taken | What it bought |
| Baseline | Took a before reading on Deductible. | A reference to judge against. |
| Define | Agreed a single definition of Deductible. | A shared definition up front. |
| Act | A CAC-to-LTV review — one variable. | Cause and effect, isolated. |
| Result | Runway extended after re-pricing a 3:1 segment | A call backed by the read. |

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

## Where teams go wrong

Keep this in mind.The errors with Deductible are predictable: one blanket rule, no context, chasing the word, raw benchmarks. Each is avoidable.

- **No segments.** Treating Deductible as one number for all. Break it out before you trust it.
- **No context.** Reporting Deductible with no baseline. A bare number cannot be judged.
- **Chasing the word.** Optimizing Deductible for its own sake. Check it tracks a real outcome.
- **Apples to oranges.** Comparing Deductible across firms raw. Adjust for pricing and cycle before you read it.
