What is Marketing Spend Efficiency?
Marketing spend efficiency measures how effectively your marketing investment converts into revenue and leads. The marketing efficiency ratio (MER) and leads-per-marketer metrics help benchmark your team's performance against industry standards. Track channel-level returns with the Marketing ROI Calculator and optimise channel allocation with the Ad Budget Calculator.
The Formula
Marketing Efficiency Ratio = Total Revenue ÷ Total Marketing Spend Leads per Marketer = Total Leads ÷ Marketing Team Size
Worked Example
A B2B company: £500,000 annual revenue, £75,000 marketing spend, 3-person marketing team, 600 leads/year.
- MER = £500,000 ÷ £75,000 = 6.67x
- Marketing as % of revenue = (£75,000 ÷ £500,000) × 100 = 15%
- Leads per marketer = 600 ÷ 3 = 200 leads/year
- Cost per lead = £75,000 ÷ 600 = £125
📌 Every £1 of marketing spend generates £6.67 in revenue. Each marketer produces 200 leads/year at £125 per lead — solid B2B performance.
Why This Matters
Budget defence
When the CFO asks "what does marketing actually deliver?", MER provides a clear answer. A 6.67x return means cutting the marketing budget by £10,000 risks losing £66,700 in revenue. Data protects budgets.
Team sizing
Leads per marketer helps determine when to hire. If each marketer generates 200 leads and sales needs 1,000 leads, you need 5 marketers — a straightforward capacity planning metric.
Common Mistakes
❌ Including all revenue in MER
MER should only include revenue influenced by marketing, not revenue from existing customer renewals, partner referrals, or founder-led sales. Inflating the numerator makes marketing look better but leads to poor budget decisions.
❌ Comparing across industries
A 5% marketing-to-revenue ratio is excellent for enterprise B2B but poor for D2C ecommerce (which typically needs 15-25%). Always benchmark against your specific industry and business model.
