Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Marketing spend ratio | Revenue available for other costs |
|---|---|---|
| $50k spend · $500k rev (10%) | 10.00% | 90.00% |
| $200k · $2M (10% SaaS mature) | 10.00% | 90.00% |
| $2M · $5M (40% SaaS growth) | 40.00% | 60.00% |
| $8k · $80k (10% small biz) | 10.00% | 90.00% |
How This Calculator Works
Enter total marketing spend (paid media + agency fees + content + tools + marketing salaries + brand + events) and total revenue over the same period. The calculator divides one by the other and multiplies by 100 to give the marketing spend ratio.
The Formula
Part as a Percentage of a Whole
Part is the portion, Whole is the total it belongs to
Worked Example
A business with $50,000 marketing spend on $500,000 of revenue runs at 10% marketing spend ratio. Industry benchmarks from Gartner: B2B average 9% to 12% of revenue; B2C average 12% to 15%; consumer goods 15% to 20%; SaaS often 40% to 60% during growth phase. Mature companies typically run lower; growth-stage companies run higher.
Key Insight
Marketing spend ratio reveals strategic posture more than operational efficiency. Growth-stage SaaS companies often spend 40% to 60% of revenue on marketing — pursuing fast growth at the expense of near-term margin. Mature consumer-goods companies run 15% to 20% — funding brand maintenance. CFOs reviewing marketing budgets often compare against industry averages without accounting for growth stage, which leads to wrong conclusions. Match the benchmark to the company's growth phase.
Frequently Asked Questions
How is marketing spend ratio calculated?
Divide total marketing spend by total revenue, multiply by 100. $50k of marketing on $500k of revenue is a 10% ratio.
What is included in marketing spend?
Paid media (search ads, social, display), agency and contractor fees, content production, marketing tools (CRM, automation, analytics), marketing team salaries and benefits, brand campaigns, events, sponsorships, PR. Excludes sales team costs in most frameworks.
What's a typical marketing spend ratio?
Gartner CMO survey averages: B2B 9% to 12% of revenue; B2C 12% to 15%; consumer packaged goods 15% to 20%; SaaS growth-stage 40% to 60%; SaaS mature 15% to 25%. Compare against same-industry, same-stage peers, not industry averages alone.
Should I include sales spend?
Usually no — sales and marketing are separate disciplines with different ROI frameworks. CAC (customer acquisition cost) combines both for unit-economics analysis, but the spend-of-revenue benchmark typically stays separate to enable industry comparison.
How does this relate to CAC?
Marketing spend ratio is a top-down allocation view; CAC (cost per customer) is a unit-economics view. Both are useful — the ratio answers 'is our overall investment level appropriate'; CAC answers 'is each customer profitable to acquire'.

Methodology & Review
Marketing spend ratio is total marketing spend divided by total revenue, multiplied by 100. The complement is the share of revenue available for everything else. The figure is the headline allocation benchmark used by Gartner, Deloitte, and similar surveys for industry comparison.
