How it works

Staffed hours = weekday hours × weekdays + weekend hours. Unstaffed hours = 168 − staffed hours. Calls outside hours per month = calls per week × after-hours share × 52 ÷ 12.

What happens to those calls matters more than how many there are. See after-hours call answering and the missed call cost calculator.

Frequently asked questions

How do I know what share of calls come after hours?

Check your phone system's call log for a typical week and count calls outside your office hours, including missed calls. That share is usually the most useful number on this page.

What counts as after hours?

Any time nobody is available to answer: evenings, weekends, holidays, and also lunch breaks or early mornings if the phones aren't covered then.
