Most solo consultants track revenue and little else. These five numbers give you an honest picture of whether your business is healthy — and what to fix next.
Revenue feels like the only number that matters when you're running a solo consulting practice. It's not. Revenue tells you what happened — these five metrics tell you what's about to happen.
Why most consultants under-measure
Solo consultants are usually great at their craft and perpetually short on admin time. Tracking business metrics feels like overhead. It is overhead — but the right metrics pay for that overhead many times over.
The goal isn't a dashboard. It's four to five numbers you check monthly that tell you where you're healthy and where you're not.
1. Utilization rate
What it is: The percentage of your available working hours that are billable.
How to calculate: Billable hours ÷ Total available working hours × 100
What to aim for: 60-75% for most consultants. Above 80% is a warning sign — it leaves no time for business development, and it's not sustainable.
What it tells you: If utilization is low, you have a pipeline problem. If it's too high, you have a capacity problem — and you're likely underpricing or over-delivering.
2. Average project value
What it is: The average fee across your completed projects.
How to calculate: Total project revenue ÷ Number of projects
Why it matters: This number should trend up over time as you get more selective and raise your rates. If it's flat or declining, you may be accepting too many small engagements to fill your calendar.
Track it by project type too. You may discover that one category of work pays 2x what another does — that's useful information for where to focus your BD effort.
3. Client acquisition cost (CAC)
What it is: How much time and money it takes to land a new client.
For consultants, simplify it: Track hours spent on business development (networking, proposals, sales calls) per month divided by new clients won. If you spend 20 hours/month on BD and win 1 client every 2 months, your CAC is 40 hours.
Why it matters: When referrals are your primary channel, CAC is low. When you're cold-calling or running paid ads, CAC is high. Knowing this tells you where to invest your scarce BD time.
4. Pipeline coverage ratio
What it is: The total value of active proposals in your pipeline relative to your monthly revenue target.
Rule of thumb: You want 3-5x your monthly target in active proposals. If you close 25% of proposals and you need $20K/month, you want $60-100K in active proposals at any given time.
Why it matters: Most consultants only look at this number when they're worried about revenue. By the time you're worried, it's already too late to fix it quickly. Check this monthly when things are good.
5. Client lifetime value (LTV)
What it is: The total revenue a client generates over the course of your relationship, including extensions, retainers, and repeat projects.
Why it matters: Consultants with high LTV invest heavily in the client relationship — they ask for feedback, stay in touch between engagements, and proactively bring ideas. Consultants with low LTV treat every engagement as a transaction and move on.
If your average LTV is close to your average first-project value, you have a retention problem. Focus on deepening existing relationships before chasing new ones.
The monthly check-in habit
Once a month (first Monday works well), spend 20 minutes reviewing these five numbers. Write them in a simple spreadsheet. Look for trends, not snapshots.
You're not trying to optimize everything at once. You're looking for the one number that's off. Fix that, then check next month.
The meta-lesson
The consultants who grow their business intentionally are almost always the ones who measure it. Not obsessively — just honestly. Four numbers in a spreadsheet beats gut feel every time.
