Overview & Methodology
Independent management consultants and fractional executives (Fractional CMO/CFO/CTO) command high billing rates ($150 to $350+/hr) but operate at lower billable utilization (50% to 65% of work time) due to extensive business development and client research.
Mathematical Formulation
Utilization % = (Billable Hours / 40 hrs) × 100. Net Earnings = (Gross Consulting Fees - Overhead) × (1 - Tax %).Optimization Best Practices
Shift clients from hourly billing to monthly advisory retainers (e.g. $5,000/mo for 25 hours of strategic advisory).
Target a 60% billable utilization rate (24 hrs/wk) to allow ample time for executive networking and thought leadership.
Charge a minimum project size or initial diagnostic fee ($2,500) to filter out low-budget prospects.
