Marketing Budget Calculator

Calculate how much you should spend on marketing based on your revenue, stage, and growth goals.

Marketing budget allocation tips

  • Start with your highest-ROI channel and fully fund it before diversifying — spreading a small budget too thin produces results in no channel.
  • Reserve 10–20% of your budget for experimentation — testing new channels, formats, or audiences that could become your next major growth engine.
  • Measure cost per acquisition (CPA) by channel, not just spend — a channel consuming 30% of budget but driving 60% of customers deserves more, not less.
  • Revisit your budget quarterly, not annually — markets move fast and the channel that worked last year may already be saturating.

How to set the right marketing budget

The most common approach to marketing budgeting is the "percentage of revenue" model — allocating a fixed proportion of annual or projected revenue to marketing. The right percentage varies significantly by stage and industry. Startups need to spend more (often 15–25% of revenue) to build brand awareness from scratch. Established businesses with strong word-of-mouth can often sustain growth on 5–10%. B2B SaaS companies typically spend 12–20% on marketing given long sales cycles and high lifetime values.

Growth goals amplify or reduce the baseline. Maintaining market position requires less spend than capturing new market share. Aggressive growth goals often require investing ahead of revenue — spending on brand and demand generation that takes 6–18 months to fully convert into measurable revenue. This calculator provides a research-backed starting point; adjust based on your actual channel performance data.

Frequently asked questions

What percentage of revenue should go to marketing?
Gartner research suggests B2B companies typically spend 6–12% and B2C companies 5–15% of revenue on marketing. Startups often spend 20–30% to build brand recognition. The SBA recommends small businesses with revenue under $5M spend 7–8% on marketing. These are starting points — the right number depends on your margins, competitive intensity, and growth ambition.
How do I prioritise marketing channels?
Prioritise channels where your target audience already spends time and where your CAC (customer acquisition cost) is lowest. For B2B SaaS, LinkedIn and content/SEO often deliver the best long-term ROI. For e-commerce, Meta and Google Shopping typically dominate. Start with 2–3 channels you can resource properly rather than 8 channels done poorly.
Should I increase marketing budget in a downturn?
Counterintuitively, companies that maintain or increase marketing spend during downturns often gain market share as competitors cut back. Ad inventory gets cheaper, competition for attention decreases, and your brand stays top-of-mind for when buyers return. The caveat: maintain budget on revenue-generating activities (performance channels) while deferring brand awareness spend if cash is tight.
