Assumptions worth checking
Using This Calculator
Scenario: check whether a client week is healthy
Use this page when you know how many hours were spent but need to see whether the week actually produced invoiceable value.
- Result factors: billable hours, non-billable hours, hourly billing rate, total tracked hours, and utilization percentage.
- Example scenario: 24 billable hours and 11 admin hours at $95/hour produces an invoice estimate plus a clear view of non-billable capacity drag.
Limitations to check before invoicing
The estimate does not apply contract caps, retainers, write-offs, minimum billing increments, taxes, platform fees, or client approval rules.
- Use the contract or invoice system for final billing.
- Check whether internal time should be priced at the same rate before using lost potential as a target.
