Billable Hours Calculator

Divide billable hours by total hours and multiply by 100. If you billed 120 of 160 hours, that is 120 / 160 = 0.75, or 75 percent utilization. Non-billable hours are simply the total minus the billable figure, so 40 in that example.

Revenue is billable hours multiplied by your hourly rate, so 138 billable hours at 125 per hour returns 17,250. The rate is optional: untick the box and the tool still reports utilization and non-billable hours without any money.

No. This tool takes the hours you have already totalled and reports utilization and revenue. It does not round time to six-minute or tenth-of-an-hour increments the way many timekeeping systems do, so round your entries first if your firm bills that way.

Utilization and revenue are rounded to two decimal places for a clean display. An uneven split like 138 of 173 hours becomes 79.77 percent rather than a long repeating decimal. The underlying division keeps full precision before rounding.

It varies by role and industry. Many agencies and consultancies target somewhere around 70 to 90 percent for client-facing staff, leaving room for admin, sales and training. Very high rates can signal burnout or unpaid overtime, so treat your own goal as the benchmark.

Any hour you cannot charge to a client: internal meetings, admin, business development, training, tooling and breaks. The calculator reports it as total hours minus billable hours, so tracking it honestly is what keeps your utilization figure meaningful.

No. Billable hours are capped at the total you enter, and the engine rejects a billable figure that exceeds the total. If you worked paid overtime, raise the total hours to include it so the ratio stays below 100 percent.

No. The currency only formats the revenue figure with the right symbol and grouping. Utilization and non-billable hours are unit-free, and the hourly rate is multiplied the same way whichever currency you pick.

Yes. Every calculation runs entirely in your browser. Your hours, rate and currency are never sent to a server or stored, so you can use it for sensitive client figures without anything leaving your device.
