## How the Model Works

```
Marketing Budget = Annual Revenue × Industry Base % × Growth Multiplier × Funding Adjustment
```

### Step 1: Industry Base Range

The published range for the company's industry and business model (B2B or B2C) from our benchmark research.

| Industry | B2B Range | B2C Range |
|---|---|---|
| Technology & Software (SaaS) | 10–15% | — |
| E-commerce / D2C | — | 12–20% |
| Financial Services / Fintech | 8–12% | 6–10% |
| Healthcare | 5–8% | 5–8% |
| Professional Services | 6–10% | — |
| Manufacturing & Industrial | 3–5% | — |
| Retail | — | 8–15% |
| Real Estate | 5–8% | 5–8% |
| Education / EdTech | 8–12% | 10–15% |
| Media & Entertainment | — | 10–18% |
| Travel & Hospitality | — | 10–15% |
| Legal Services | 5–8% | — |
| Non-Profit | — | 5–10% |
| Construction & Trades | 3–6% | — |
| Food & Beverage | — | 8–15% |
| Automotive | 4–7% | — |
| Energy & Utilities | 2–5% | 2–5% |
| Logistics & Supply Chain | 3–6% | — |
| High-Growth Startups | 20–30% | 20–30% |

### Step 2: Company Size Multiplier

Smaller companies spend a higher percentage of revenue because fixed costs don't amortize as efficiently.

| Revenue Band | Multiplier |
|---|---|
| Under $5M | ×1.25 |
| $5M – $50M | ×1.0 |
| Over $50M | ×0.8 |

### Step 3: Growth Multiplier

Companies targeting higher growth require proportionally larger budgets.

| Growth Target | Multiplier | Typical Spend % |
|---|---|---|
| Maintain (<10% YoY) | ×0.7 | 3–7% |
| Steady (10–25% YoY) | ×0.85 | 5–10% |
| Growth (25–50% YoY) | ×1.0 | 8–15% |
| Aggressive (50–100% YoY) | ×1.2 | 12–20% |
| Hypergrowth (100%+ YoY) | ×1.45 | 20–30% |

### Step 4: Funding Adjustment

Equity-backed companies spend roughly 2× what bootstrapped companies spend on marketing (SaaS Capital 2026). We apply a dampened adjustment to avoid double-counting with growth ambition.

| Funding Status | Adjustment |
|---|---|
| Bootstrapped / Profitability-first | ×0.9 |
| Equity-backed (VC/PE) | ×1.1 |

## Channel Allocation

| Channel | Recommended % | Best For |
|---|---|---|
| Google Ads (Search & Display) | 25–35% | High-intent traffic, quick results |
| Social Media (Meta, LinkedIn, TikTok) | 20–30% | Brand awareness, retargeting |
| SEO & Content Marketing | 15–25% | Long-term organic growth |
| Email Marketing | 5–10% | Retention, highest ROI channel |
| Influencer & Affiliate | 5–10% | Social proof, niche audiences |
| Other (Events, PR, Direct Mail) | 5–15% | Specific goals, brand building |

## Revenue Projection Formula

```
Clicks = Budget ÷ Average CPC
Conversions = Clicks × Conversion Rate
Revenue = Conversions × Average Order Value
ROAS = Revenue ÷ Budget
```

## Research Sources

| Study | Publisher | Sample | What It Measures |
|---|---|---|---|
| 2026 CMO Spend Survey | Gartner | 401 CMOs | Marketing budget as share of revenue (7.7% average) |
| 2026 Spending Benchmarks for Private B2B SaaS | SaaS Capital | 1,000+ companies | Departmental spend as % of ARR |
| 2026 State of Marketing Report | HubSpot | 1,200+ marketers | Budget allocation trends, channel ROI |

## Confidence Levels

- **Anchored:** Result falls within the centre of surveyed panels. Directly supported by published benchmark data.
- **Modeled:** Result at the edge of surveyed panels — hypergrowth, unlisted industries, or extreme company sizes. Directional, not definitive.

## Limitations

- The model is multiplicative: it treats industry, size, growth, and funding as independent factors when in reality they correlate.
- Industry baselines describe a blended panel. Within any industry, the spread between individual companies is far wider than the published range.
- The funding effect is anchored in B2B SaaS. Applied to other industries it is directional, not measured.
- The output is always a range with a stated confidence — not a single number.

## Worked Examples

### Series B B2B SaaS, $2M ARR, 25% growth target
- Recommended: $200K–$300K/yr (10–15% of revenue)
- Midpoint: $250,000 (12.5%)
- Confidence: Anchored
- Derivation: B2B base 10–15% × size ×1.0 × growth ×1.0 × equity ×1.1

### D2C E-commerce, $500K revenue, doubling next year
- Recommended: $80K–$120K/yr (16–24% of revenue)
- Midpoint: $100,000 (20%)
- Confidence: Modeled
- Derivation: B2C base 12–20% × size ×1.25 × growth ×1.45 × bootstrapped ×0.9

### Manufacturing, $10M revenue, maintain mode
- Recommended: $250K–$375K/yr (2.5–3.8% of revenue)
- Midpoint: $312,500 (3.1%)
- Confidence: Anchored
- Derivation: B2B base 3–5% × size ×0.9 (efficiency) × growth ×0.7 × bootstrapped ×0.9

### Professional Services, $1.5M revenue, steady growth
- Recommended: $60K–$105K/yr (4–7% of revenue)
- Midpoint: $82,500 (5.5%)
- Confidence: Anchored
- Derivation: B2B base 6–10% × size ×1.0 × growth ×0.85 × bootstrapped ×0.9
