Billable Hours Calculator

The Billable Hours Calculator turns your time into clear numbers so you can see the money your work brings in and how much of your effort is actually paid. It is built for consultants, agencies, lawyers, tradespeople and anyone who tracks time against client work. You enter the total hours you worked in a period, the hours that were genuinely billable, and your hourly rate. The tool multiplies billable hours by the rate to give billable revenue, then divides billable hours by hours worked to give your utilisation percentage, and shows the non-billable hours left over. Utilisation is the heartbeat of any time based business. Hours worked include everything you did, while billable hours are only the slice a client will pay for, so the gap shows time spent on admin, sales, internal work and downtime. Watching that gap helps you spot where the day disappears and whether your rate and workload add up. This view is useful weekly to stay on track and monthly to plan capacity and pricing. Good practice is to log time as you go rather than reconstructing it later, because memory inflates billable hours and hides the real picture. Aim for a sustainable utilisation target rather than the highest possible number, since chasing 100 percent burns people out and leaves no room for growth work. Review your rate alongside utilisation, because a healthy rate at moderate utilisation often beats a low rate run flat out. Use the result to set goals, quote with confidence and protect time for the work that wins future clients.

Revenue = billable hours x rate. Utilisation = billable / worked. Estimate only, not financial or tax advice.
