Billable Percentages

[Penelope]

I was wondering if anyone can give me a general rule of thumb on what per cent of an LA’s total hours should be billable. I realize this is very much based on years of experience, role, company size, etc. I heard something once like:

Entry level: 90%
Landscape Architect: 80%
PM: 70%
Principal: 50-60%

This is assuming of course that a PM and Principal is spending more time on business development and administrative tasks. Can anyone confirm these or is it just all over the place depending on the size of the firm?

These percentages could be used as a general rule of thumb. In practice, minimum billable hours are all over the place. Every firm has its own targets and other metrics that influence the minimums; including firms that don’t measure billable hours at all.
