The formulas
- Direct cost = sum of (hours x cost per hour) + unreimbursed costs
- Margin = fees - direct cost
- Margin % = margin / fees
How it works
Cost per hour is what each level costs you, not the rate you charge. The margin here is before overhead, so it shows what the engagement contributes to overhead and profit.
