# Utilization and Realization: The Two Numbers That Drive Professional Services Profit

Capstone CFO

**Short answer:** In a professional services firm, profit comes down to two questions: how much of your people's time is spent on client work (utilization), and how much of that work turns into cash at full value (realization). A few points of improvement in either can change firm profitability dramatically, because the cost of your people is already fixed.

## The definitions

| Metric | Formula | What it reveals |
| --- | --- | --- |
| Utilization | Billable hours ÷ available hours | How much capacity is used on client work |
| Billing realization | Amount billed ÷ standard value of hours worked | Write-downs before invoicing |
| Collection realization | Amount collected ÷ amount billed | Write-offs and discounts after invoicing |
| Overall realization | Amount collected ÷ standard value of hours worked | How much of the work turns into cash |

## Why small changes matter

Because salaries are largely fixed, extra billable hours or fewer write-downs flow almost directly to profit. A firm that improves overall realization by a few points often sees a much larger percentage gain in partner profit.

## Common causes of low numbers

- Fixed-fee work that overruns its budget
- Scope creep that is never billed
- Senior people doing junior work
- Slow billing, which makes clients question invoices
- Discounting to win or keep clients

## How to improve

1. Report utilization by person and role weekly.
2. Review write-downs by client, matter and partner monthly.
3. Price and scope engagements with clear change-order rules.
4. Delegate work to the right level.
5. Bill promptly and follow up on collections consistently.

## How Capstone CFO helps

- Build utilization and realization reporting from your practice management system
- Identify the clients, matters and services that lose value
- Set targets by role and track them in a monthly scorecard
- Improve pricing, scoping and billing practices
- Connect people metrics to firm profitability and partner compensation

## Frequently asked questions

### What is a good utilization rate?

It depends on role and firm type. Junior staff typically carry higher targets than partners, who spend more time on business development and management.

### Should we track time on fixed-fee work?

Yes. Time data shows whether fixed fees are priced correctly.

### Who should see these metrics?

Partners and practice leaders monthly; individuals should see their own numbers.
