The assumptions behind it
Three values are fixed in the staff time calculation. Queries arrive on 250 working days a year. One full-time person works 1,880 hours a year: 47 weeks of 40 hours. A working day is 8 hours. If any of them is wrong for your business, tell us and we will rerun it with your figures.
- working days a year
- 250
- working hours a year per person
- 1,880
- in a working day
- 8 hours
The calculator costs staff time at salary alone, so the result is a conservative figure. For the build-up with employer National Insurance and pension, read What routine technical support calls really cost a manufacturer.
