effort per meeting (CPM) is the most useful metric for evaluating B2B prospecting effectiveness. Unlike lead performance, it measures the real effort to put a salesperson in front of a prospect who has the scope, authority and buying intent.
How to calculate B2B effort per meeting
Formula: CPM = Total prospecting effort / Number of qualified meetings booked over a given period.
Total effort includes: salaries dedicated to prospecting, tools, data, paid campaigns, management share. A qualified meeting = decision-maker who confirmed interest and has potential scope.
CPM benchmark by sector (Lead-Gene 2026 data)
B2B SaaS (ACV audit-based scope): CPM audit-based scopeost effective channel: cold email + LinkedIn.
Consulting and professional services: CPM audit-based scopeDominant channel: LinkedIn.
Construction, engineering, industry: CPM audit-based scopeost effective: phone + email.
Commercial real estate: CPM audit-based scopeStrong seasonality (Q2 and Q3 = peaks).
Finance, banking, insurance: CPM audit-based scopeLong cycles, multiple decision-makers.
Healthcare, medtech, biotech: CPM audit-based scopeLow no-show rate (12%).
E-commerce and retail B2B: CPM audit-based scopeHigh volume, short cycles.
Education and EdTech: CPM audit-based scopeBudget peak in Q3 and Q1.
What varies CPM within a sector
ICP quality: a precise ICP reduces CPM by 40 to 60%.
Message personalisation: message on real intent signal → CPM reduced by 35 to 50%.
Channel used: wrong mix can double CPM.
Timing: contacting on active signal → CPM reduced by 50 to 70%.
Calculate your target CPM
Formula: Target CPM = Average ACV × Gross margin × Closing rate × 0.1.
Examples: SaaS ACV audit-based scope × 75% × 20% × 0.1 = Target CPM audit-based scopeConsulting ACV audit-based scope × 60% × 25% × 0.1 = Target CPM audit-based scope
If your current CPM exceeds 2× the target CPM, your acquisition is loss-making.
Levers to reduce CPM
Lever 1: refine ICP on your 10 last won deals.
Lever 2: concentrate 70% of prospecting effort on prospects with active intent signals.
Lever 3: reduce no-show rate (confirmation D-24h + D-2h) → from 20% to 8-10%.
Lever 4: multi-touch automation → prospect via 3 channels converts 3.2× better than 1 channel.
Every month without a lead machine is revenue handed to your competitors. 30 min to see the gap.
