Content brief: "how to calculate customer acquisition cost"

Site: fundmetric.test (fictional finance dashboard for startups) Audience: seed stage founders who are not finance experts Length: about 1,800 words (your target) Keyword volume: unavailable (no Ahrefs or Semrush access this session); not estimated. Sources: your pasted SERP notes and People Also Ask questions. I did not open the result pages myself.

Intent

Informational, with a "do it now" slant: the searcher wants a method they can apply to their own numbers. Evidence: the top three results are a glossary definition, a long guide and a calculator. Google serves people who want to understand CAC and then compute it.

SERP summary with URLs

# URL Format Covers Misses
1 https://glossaryhub.test/cac Glossary page, about 300 words The formula Context on what to include; any example
2 https://saasguide.test/blog/cac-guide Long guide Blended vs paid CAC, channels A worked example
3 https://calcly.test/cac-calculator Calculator, two input boxes Computes a number What to put in the boxes; what the result means

Shared ground: all three cover the basic formula. None, per your notes, walks a reader from raw spending data to a CAC number with every inclusion decision explained.

Gaps fundmetric.test can credibly fill: 1. A complete worked example (missing from results 1 and 2). 2. A clear checklist of what counts as acquisition spend, the question result 3 leaves to the user. People Also Ask confirms it: "Should salaries be included in CAC?" 3. A bridge from CAC to payback and LTV, which a finance dashboard with a unit economics feature can speak to with authority.

Angle

"How to calculate CAC, step by step, with a worked example for founders who aren't finance people." One hypothetical seed stage startup goes from a spending list to a CAC number, then to payback, explaining each judgment call. Fundmetric owns this because its unit economics feature tracks CAC, LTV and payback, so the article ends naturally with "or let your dashboard keep it current."

Do not reuse headings from the three results word for word.

Outline

H1: How to Calculate Customer Acquisition Cost: A Step by Step Guide With a Worked Example

  • Intro (about 120 words, no heading): what CAC tells a seed founder (where growth money goes, what investors will ask), and a promise of the worked example.

  • H2: What customer acquisition cost measures (about 150 words): plain definition; one paragraph on why it matters at seed stage. Keep it short; result 1 already owns the bare definition.

  • H2: The CAC formula, explained in plain words (about 250 words): show the formula once, then explain each part. The formula wording must be sourced (see Facts to source).

  • H3: What counts as acquisition spend: a checklist (ad spend, sales and marketing salaries, tools, agencies, content costs) and what to leave out, such as product engineering. Answers the salaries question directly.
  • H3: Who counts as a new customer: paying customers, not signups or trials; pick one definition and keep it.

  • H3: Matching the time period: spend and customers must come from the same period; monthly vs quarterly.

  • H2: Worked example: one startup's CAC from start to finish (about 450 words, the core of the piece): a fictional company with round numbers, labeled "hypothetical example" in the article. Show a table: spend by category, total, new customers, CAC. Then repeat it with paid channels only to show paid CAC.

  • H2: Blended CAC vs paid CAC (about 200 words): define both (sourced), say when each helps, and point back to the example's two numbers. Add what result 2 lacks: a concrete example.

  • H2: Mistakes that skew your CAC (about 250 words): leaving out salaries, mixing periods, counting trials as customers, ignoring founder sales time. One short paragraph each.

  • H2: From CAC to payback and LTV (about 250 words): explain CAC payback and the LTV to CAC ratio in plain terms, using the hypothetical example. Answers two People Also Ask questions. Any "good ratio" benchmark only if sourced; otherwise say it varies.

  • H2: Keep your CAC current automatically (about 100 words): short CTA section linking to the unit economics feature page.

  • FAQ (about 100 words, optional): short answers to the three People Also Ask questions.
