$/hr
This calculator assumes 4.33 weeks per month and treats all non-billable time as a utilization drag. It is directional by design, but it makes weekly capacity decisions easier to see.

What good billable review looks like

The hours matter, but the reason they are billable matters too.

Client and task already attached

The more work arrives already scoped, the less time you spend explaining the bill later.

Weekly review before send

You want to find gaps while the work is still fresh, not when the invoice is already due.

Invoice draft from the same record

The cleanest billing workflow starts with tracked work, not with a blank invoice screen.

FAQ

Questions people usually ask while sizing billable capacity

What does this billable hours calculator estimate?

It estimates what your current weekly billable hours produce at your effective rate, along with utilization and the value of even small recovered hours.

Should I include admin time here?

Yes. The calculator works better when you include non-billable admin hours because they show how much of your tracked week is really turning into revenue.

Why connect this to Clockout?

Because improving billable output is not only about finding more hours. It is often about keeping the work record strong enough that fewer hours leak out before billing.
