Essential Legal Billing Metrics and KPIs for Law Firm Success

Why Billing Metrics Matter

What gets measured gets managed. Firms that track billing metrics consistently tend to see better realization, fewer write-offs, and faster collections, but only if they track the right ones.

Essential Billing Metrics

1. Utilization Rate

Formula: Billable Hours ÷ Available Hours

Common rules of thumb:

• Partners: 1,500-1,800 hours
• Associates: 1,800-2,000 hours
• Target utilization: 75-85%

2. Realization Rate

Formula: Collected Revenue ÷ Value of Time Worked

This tells you what percentage of worked time actually becomes revenue:

• Top performers: 95%+
• Average: 85-90%
• Below 80%: Improvement needed

3. Collection Rate

Formula: Collected ÷ Billed

Measures effectiveness at collecting billed amounts:

• Target: 95%+
• Average: 90%
• Action needed: Below 88%

4. Write-Off Rate

Formula: Write-Offs ÷ Gross Billing Value

Track separately:

• Pre-bill write-offs
• Post-bill adjustments
• Bad debt write-offs

5. Days Sales Outstanding (DSO)

Formula: (A/R Balance ÷ Annual Revenue) × 365

Measures collection speed:

• Excellent: Under 50 days
• Good: 50-70 days
• Needs work: 70-90 days
• Critical: 90+ days
