Billable hours ÷ (working hours − leave) × 100. Non-billable time is not necessarily idle time.
Calculated in your browser. No email required.
Capacity = people × available hours per person × planned delivery percentage. Assumes comparable skills and working patterns; exclude holidays only once.
Calculated in your browser. No email required.
Margin = (revenue − included costs) ÷ revenue × 100. Exclude vendor time from employee hours to avoid double counting. This is not net profit.
Calculated in your browser. No email required.
Attributed cost = people × unallocated hours × hourly cost. This is not a guaranteed cash saving or a measure of waste.
Calculated in your browser. No email required.
Required rate = cost ÷ (1 − margin / 100) ÷ billable hours. Uses margin, not markup. Excludes tax and does not predict market pricing.
Calculated in your browser. No email required.
The formulas calculate directly from the figures you enter. Missing time records, inaccurate cost rates or incomplete demand will still produce an unreliable estimate. Review the assumptions and use approved data wherever possible.
Your reporting system may use different leave exclusions, cost components, revenue timing or rounding rules. Compare definitions before comparing the final number. The glossary linked in the footer explains the related terms.
The capacity tool compares hours, not individual skills or constraints. Actual allocation also depends on experience, availability by date, location, client requirements and existing commitments.
A walkthrough can help you explore how resource plans, delivery records and commercial information fit your process.
