Marketing Budget Calculator
Knowing how much to invest in marketing can be one of the hardest decisions for any business. Spend too little and growth stalls, spend too much without a plan and budgets quickly disappear. Our Marketing Budget Calculator helps you find the right balance by turning your business revenue and growth goals into a clear, structured marketing budget.
| Scenario | Budget % | Budget (£) | Leads | Customers | Revenue (£) |
|---|
🎯 Start with the 5–12% rule
Most businesses allocate 5–12% of revenue to marketing. Startups and growth-focused brands often invest closer to 20% to build awareness and acquire initial customers faster.
📊 Track cost per lead, not just spend
Knowing your CPL by channel lets you reinvest in what works. If paid search generates leads at £20 but content generates them at £8, shift budget accordingly.
🔄 Plan for a 70/20/10 split
70% to proven channels, 20% to emerging tactics, 10% to experimental. This keeps performance stable while building capability in new areas over time.
📅 Review quarterly, not annually
Marketing conditions shift fast. Building in quarterly reviews lets you redirect budget from underperforming channels before large sums are committed.
🧲 Prioritise LTV, not just CAC
A customer costing £100 to acquire but worth £2,000 over their lifetime justifies more spend than one costing £30 but churning after a single purchase.
⚖️ Balance brand and performance
Performance marketing drives short-term results; brand investment drives long-term pricing power. A blend of roughly 40% brand / 60% performance is a strong starting point.
🔍 Account for production costs
Many calculators only model media spend. Factor in creative production, tools, agency fees, and staff time — these often add 20–40% to a pure media budget.
📈 Set budget to revenue targets, not gut feel
Work backwards from your growth goal. If you need 200 new customers and your acquisition cost is £150 each, your minimum acquisition budget is £30,000.
