## Short Definition

## 一言でいうと

CAC is the sales and marketing cost required to acquire one customer.

## 計算方法

- Basic formula | CAC = sales and marketing acquisition cost / new customers | Measures acquisition cost per customer

## 含めるもの / 含めないもの

- Include | Advertising, sales labor, marketing spend, acquisition tooling | They fund acquisition
- Exclude | Customer support, product development, G&A | They are not direct acquisition spend

## 意味

## 変動要因 / ドライバー

- Price and sales cycle | Higher ACV often requires more effort | Read with payback

## 判断するときの注意点

- Do not judge CAC alone; pair it with LTV and gross-margin payback.

## よくある誤解 / 落とし穴

- Mixing brand or existing-customer spend can distort acquisition efficiency.

## 最小例

Example: 10 million yen of acquisition spend for 100 customers gives CAC of 100,000 yen.
