Billing Rate Multiplier Calculator
If you pay an employee $30/hour, you cannot bill them out at $45/hour and survive. You must account for overhead (rent, software, insurance) and non-billable time (marketing, admin).
The Industry Standard
Most healthy architecture firms operate with a net multiplier between 2.75 and 3.25. This means a $30/hr employee is billed to the client at $85 to $100/hr.
