+# Budget Planning — Scientific Methods for Setting the Marketing Budget
+
+The problem with most SaaS marketing budgets is that they're pulled out of thin air — a number that hopefully doesn't constrain growth too much, but doesn't anchor in customer-acquisition economics either. The result: when someone asks "why this number?" there's no answer.
+
+Two scientific methods solve this. Use one (not both) in Section 8 (Revenue) and Section 10 (12-month outlook) of every plan.
+
+Excerpted and adapted from *Founding Marketing* by Corey Haines.
+
+## Method 1 — Revenue-Based (5–40% of annual revenue)
+
+**Direction:** budget → revenue goal.
+
+You start with what the company can comfortably spend on marketing, then forecast what revenue that spend can plausibly generate.
+
+### The ranges
+
+| Posture | % of ARR | When to use |
+|---|---|---|
+| **Conservative (profit-preserving)** | 5% | Established business focused on profit distribution; bootstrapped; founder-paid customer base |
+| **Standard growth** | 15–25% | Most healthy SaaS in the seed-to-Series-A range |
+| **Aggressive growth (deploying raised capital)** | up to 40% | Recently funded round, mandate to deploy fast, board accepts burn |
+
+For reference: public SaaS companies routinely report sales-and-marketing spend between 20% and 55% of revenue (Zoom historically ran between 20% and 55% across years).
+
+### The math (Conservative example)
+
+Business at $1M ARR, 5% allocation:
+
+- Annual marketing budget: **$50,000**
+- Blended CAC: $100 → can acquire **500 new customers**
+- ARPC: $50/mo → adds **$300K** to ARR
+- Account for 15% annual churn → 85% × $300K = **+$255K net new ARR**
+- End-of-year goal: **$1.255M ARR**
+
+### The math (Aggressive example)
+
+Business at $1M ARR, 40% allocation:
+
+- Annual marketing budget: **$400,000**
+- Blended CAC: $100 → can acquire **4,000 new customers**
+- ARPC: $50/mo → adds **$2.4M** to ARR
+- End-of-year goal: **$3.4M ARR**
+
+### Two keys to making this method work
+
+1. **Know your blended CAC** (see "Calculating CAC" below)
+2. **Match the allocation percentage to your actual ambition.** A founder running 5% allocation while telling the board they expect to triple revenue is showing two incompatible signals.
+
+## Method 2 — Goal-Based (reverse-engineered from the revenue target)
+
+**Direction:** revenue goal → budget.
+
+You start with the revenue goal and work backward through the unit economics to derive the budget required to hit it. Best for:
+
+- Companies just starting up (no historical CAC baseline yet, working from first principles)
+- Companies anticipating outside capital (need to defend the ask)
+- Companies using revenue-based financing (Pipe, Capchase, Founderpath)
+
+### The formula
+
+```
+Marketing budget = [(New ARR / (ARPC × 12)) × CAC] / annual retention rate
+```
+
+### Worked example: $1M ARR → $2M ARR
+
+Step 1 — How much new ARR per customer?
+ARPC × 12 = $50 × 12 = **$600 ARR per new customer**
+
+Step 2 — How many new customers do we need?
+$1,000,000 / $600 = **1,667 new customers**
+
+Step 3 — What's the raw acquisition cost?
+1,667 × $100 CAC = **$166,700**
+
+Step 4 — Account for churn (15% annual = 85% retention)
+$166,700 / 0.85 = **$196,118** (round to **$200K**)
+
+When someone asks how you got to the budget, walk them through the four steps. It's defensible.
+
+### Why this formula and not something simpler
+
+The four steps each correspond to a real economic reality:
+- Step 1 converts MRR-language into the ARR-language a board talks in
+- Step 2 names the customer count, which is what the funnel actually has to deliver
+- Step 3 anchors the budget in the cost of acquisition
+- Step 4 acknowledges that churned customers don't count toward net new ARR, so the budget needs to cover the gap
+
+### Required buffer
+
+**Always add 10–20% as "experimental budget"** on top of the formula output. CAC is the main dependency; if CAC comes in 50% higher than estimated, the cascading effect is missing the revenue goal. It is much cheaper to overestimate CAC than to underestimate it.
+
+The experimental budget also funds the experiments that find your next channel before your current one plateaus (see `growth-patterns.md` — channel S-curves).
+
+## The VC growth path (3-3-2-2-2 rule)
+
+Once a company has crossed $1M ARR and taken a Series A, the implicit benchmark VCs expect is:
+
+| Year | ARR multiple | Cumulative ARR (from $1M start) |
+|---|---|---|
+| Year 0 | — | $1M |
+| Year +1 | 3× | $3M |
+| Year +2 | 3× | $9M |
+| Year +3 | 2× | $18M |
+| Year +4 | 2× | $36M |
+| Year +5 | 2× | $72M |
+| Year +6 | 2× | $144M |
+| Year +7 | 2× | $288M |
+
+That's the 3-3-2-2-2 rule. Useful when:
+
+- The plan needs to map 12-month and 36-month milestones to VC expectations
+- The founder is mid-raise and the board needs to see a plausible path to the next round
+- Section 10 (12-month outlook) needs anchoring against an industry benchmark, not just internal ambition
+
+Most companies miss it. That's fine. Knowing the benchmark gives the team a defensible reason to either match it or explicitly choose not to.
+
+## Calculating CAC (blended, not paid-only)
+
+If there's no historical CAC, use a baseline: **one year of revenue from the smallest paid plan.** Deploy the budget, capture actual CAC data, replace the baseline with the measured number for the next planning cycle.
+
+For an established CAC calculation, **CAC must be blended.** Include:
+
+- Marketing salaries (full loaded cost, not just base)
+- Advertising spend
+- Marketing tech stack costs
+- Content production costs (writers, designers, video editors)
+- Agency / contractor retainers
+- SDR / BDR salaries if doing outbound
+- Tools (CRM, marketing automation, analytics)
+
+Then divide by the number of new customers acquired in the period. That blended number is the one to use in either budgeting method.
+
+The mistake to avoid: calculating CAC from paid ad spend alone. A company that "doesn't run ads" still has a CAC — it's just hidden in the content team, the founder's time, the SEO contractor, the conference booth.
+
+## The reality check on forecasting
+
+This whole framework derives a budget and a revenue goal — not a 12-month month-by-month forecast accurate to the dollar.
+
+**Unless the company is publicly traded, all forecasts are educated guesses.** No startup under $100M ARR reliably hits forecasts to the month. The honest framing for the plan:
+
+- The annual goal is a defensible direction-of-travel
+- The budget is the resource commitment that makes the goal plausible
+- The 90-day roadmap (Section 9) is what's actionable now
+- Month-to-month variance is expected; quarterly review is when the plan adjusts
+
+What's actionable: how to deploy the budget, what concrete moves to execute, what to adjust when real data comes in.
+
+What's not actionable: trying to forecast traffic, pipeline, retention curves, conversion rates, and channel mix all down to the decimal point and expecting that forecast to hold. Founders who over-engineer the forecast tend to spend the plan period explaining variance instead of executing.
+
+**Rule for the plan:** the budget number is honest. The annual goal is honest. The month-by-month projection is illustrative.
+
+## How this flows into the plan
+
+| Section | What to include |
+|---|---|
+| **3 (Current state)** | Current monthly marketing spend broken down by line (paid, tools, content, headcount, retainers). Compute current %-of-ARR allocation. |
+| **8 (Revenue)** | The unit-economics table (CAC, ARPC, churn) that feeds whichever budget method you're using. |
+| **10 (12-month outlook)** | Apply Method 1 or Method 2 to derive the 12-month budget and the resulting revenue goal. Anchor against the 3-3-2-2-2 rule if Series A+ and VC-backed. |
+| **11 (Ops stack)** | Show the budget allocation across the AARRR stages — what % to Acquisition, Activation, etc. The ops-stack mapping informs which line items grow when the next funding tier unlocks. |
+| **13 (Open decisions)** | If CAC is unknown or contested, flag it as the highest-impact open decision — every other number depends on it. |
+
+## When to choose which method
+
+- **Method 1 (Revenue-Based)** when the company has historical CAC data, a profit/burn posture, and the question is "given our posture, what's a plausible goal."
+- **Method 2 (Goal-Based)** when the company has a specific goal (board mandate, VC milestone, fundraise target) and the question is "what budget do we need to hit it."
+
+For most plans in the seed-to-Series-A range, Method 2 is more useful — it forces the conversation about whether the goal is funded.
