Utilisation, bill rate and gross margin: the three numbers a delivery leader owns
Utilisation tells you how much of your capacity is sold, bill rate tells you what it is sold for, and gross margin tells you whether it was worth it. A delivery leader who can move all three is running a business.
Utilisation
Formula: billable hours ÷ available hours (after leave and public holidays). Healthy: 75–85% for engineers, 50–65% for leads (the rest is pre-sales, mentoring, escalations). Trap: counting internal projects as billable.
Bill rate and realisation
Bill rate is the contracted hourly or daily rate. Realisation is what you actually collected divided by what you should have billed at rate card; discounts, write-offs and unbilled overruns show up here. Healthy realisation: above 85%. Trap: tracking rate card and never tracking realisation.
Gross margin
Formula: (revenue − fully loaded delivery cost) ÷ revenue. Healthy in digital commerce services: 40–55%. Trap: excluding shared roles (architecture, DevOps, PMO) from cost so pods look better than the practice.
How they move together
Raise utilisation with the same rates and margin rises fast — until quality falls and realisation drops. Raise rates and utilisation may fall — but margin per hour rises. The lever most practices ignore is realisation: stop leaking through unbilled scope and margin rises with no change to people or price.
A worked example
Illustrative figures, not any one company's. A 10-person pod with a fully loaded cost of INR 1.2 crore a year, 80% utilisation and a blended bill rate of INR 4,500 an hour on 1,800 available hours each earns about INR 6.5 crore: roughly 81% margin before shared cost. After a fair share of architecture, PMO and management, around 48%. Drop realisation to 75% and the same pod makes 38%.
Frequently asked questions
- What is a good utilisation rate for a services team?
- 75–85% for delivery staff; higher is unsustainable, lower erodes margin.
- What is realisation?
- Collected revenue divided by revenue at rate card; it measures discounts, write-offs and unbilled work.
- What gross margin should a digital agency target?
- 40–55% on delivery work after fully loaded cost including shared roles.
