Frequently asked questions

Consultants typically bill 60-75% of worked hours. Above 80% is hard to sustain; below 50% means most of your week is not earning.
Billable hours = hours worked × weeks worked × utilisation. Multiply by your rate: 40 hours × 48 weeks × 70% = 1,344 hours.
Plan on 46-48 working weeks. Freelancers also lose days to admin, marketing and sickness, which is why the billable rate is below 100%.
