What this tool does
Nobody bills every hour: quoting, admin, sales and learning all take real time and none of it invoices. The effective rate is the honest one to compare against a salary, because it spreads your headline rate over the whole working week rather than just the billed part.
Formula
utilisation = billable hours ÷ available hours × 100
