Billable Hours Calculator — illustrative example

INPUT
Work from 09:00 to 12:00 with a 30-minute unpaid break; rate USD 60/hour; bill exact time.

RESULT
Elapsed time: 3 hours.
Billable time: 2.5 hours.
Fee: 2.5 × USD 60 = USD 150, before any supplied taxes or expenses.

REVIEW
Billable hours should follow the client's rounding and break rules. Keep actual duration visible alongside billed duration so a rounding policy does not hide how the total was calculated.
