Should a Consultant quit their day job? The exact numbers.
Retainer-model income at 70% utilization, covering 1.5x your essential expenses.
Consulting is retainer + hourly. The 70% utilization floor prevents you from burning out at 100% (which is unsustainable after month 3). The 1.5x coverage ratio builds in capacity for pipeline gaps between engagements.

FAQ — Part-time consultant
What counts as 'utilization' for consultants?
Paid client hours divided by your target working hours (typically 30/week for solo consultants, leaving 10 for biz dev + admin). 70% utilization = 21 paid hours/week.
Why not aim for 100% utilization?
Burnout and no pipeline. At 100% you have no capacity to replace a departing client — when (not if) they leave, you drop to 0% with no backfill.
I have one huge retainer. Can I quit now?
Probably not. Single-client concentration above 60% is the #1 cause of failed consulting transitions. Diversify to 3+ retainers first.
How much runway should I have on top?
9 months recommended — consulting pipelines have 60-90 day delays between pitch and close, so you need the buffer to survive a dry quarter.
