How the math works
Three numbers decide a services firm's margin, and most dashboards only show the first one.
Effective revenue / consultant = bill rate x capacity x utilization x realization
Margin / consultant = effective revenue - fully loaded cost
Gross margin % = total margin / total revenueUtilization and realization both multiply revenue, so they compound. A team at 90 percent utilization and 80 percent realization produces less effective margin than a team at 78 percent utilization and 95 percent realization at the same rate. That is why utilization alone is a misleading health metric.
Why pushing utilization can lower margin
Above a firm specific threshold, every extra point of utilization removes the slack senior people use to scope accurately, review quality, and control change. Realization then falls faster than utilization rises: more hours billed, fewer of them collected at full rate. The paradox box above shows your own crossover by modeling a plus 10 point utilization push against an 8 point realization drop. For the full argument, see The Utilization Paradox.
Closing the leakage
The realization leakage figure is billed value you never collect: discounts, write offs, scope creep absorbed as courtesy hours. Servantium surfaces it at quote time and tracks it per engagement, so the leak is visible before month end instead of after. See how the platform handles it.
