Analytical Proof & Invariants

Machine Precision

Governing Mathematical Formula:

Overall Realization = (Billed Hours / Logged Hours) × (Collected Revenue / Billed Revenue)

Step-by-Step Mathematical Derivation

Standard Value Potential

Gross Standard Value = 1,800 hours × $475/hr = $855,000.00.

Billing Realization Haircut

Billed Invoices = $855,000 × 91% = $778,050.00 ($76,950 written down by billing partner).

Collection Realization Cash Receipt

Collected Cash = $778,050 × 94% = $731,367.00 ($46,683 uncollected or disputed).

Effective Realized Rate

Overall Realization = 91% × 94% = 85.54%. True Realized Hourly Rate = $731,367 / 1,800 hours = $406.32/hour.

What is considered a healthy realization rate in law firms? +

AmLaw 200 benchmarks target 92% to 95% billing realization and 95% to 97% collection realization, yielding an overall realization rate above 88%.
