Marketing Budget Calculator

A strong marketing budget should connect business goals with channel strategy. This calculator helps small and mid-sized businesses create a planning budget across SEO, paid search, website improvements, content, email, analytics, and conversion optimization.

What this calculator does

Estimate a marketing budget based on revenue, growth stage, and channel priorities.

How to use it

Enter annual revenue, growth aggressiveness, and channel priority. The calculator estimates annual and monthly marketing budget, then suggests a budget allocation by channel.

Formula and assumptions

• Budget range is based on selected growth stage percentage of annual revenue.
• Suggested allocation changes by business type and website need.
• Monthly values divide annual recommendations by 12.

Assumptions

• The calculator uses planning percentages and should not replace a custom forecast.
• Early-stage growth usually requires a higher marketing investment as a percentage of revenue.
• Budget allocation should change based on goals, competition, sales cycle, and current channel performance.

Model details and limits

• The percentages and channel allocations are illustrative planning assumptions used by this tool. They are not industry benchmarks or a forecast. Maintenance uses 3%–6%, growth 7%–12%, and aggressive growth 12%–20% of annual revenue.
• Channel budgets allocate the midpoint of the monthly range. Lead-generation allocation is SEO/paid/website/email 30%/35%/20%/15%; ecommerce is 25%/40%/15%/20%; local is 40%/30%/20%/10%.
• A high website need shifts 10 percentage points to website/CRO, taking 5 points each from SEO and paid media. Low and medium website need retain the base allocation. The shares total 100%; compare cash flow, margins and measured acquisition economics before committing.

Worked example

For $1,000,000 annual revenue at the growth stage, the annual range is $70,000–$120,000 and the monthly range is $5,833.33–$10,000. The $7,916.67 monthly midpoint allocates $2,375 SEO, $2,770.83 paid media, $1,583.33 website/CRO and $1,187.50 email/analytics for the default lead-generation business.
