Billable Days Per Year Calculator NZ

This billable days calculator works out how many days of the year you can actually charge a client for, which is the number every contractor's day rate and income target rests on. A year looks like 260 or so working days, but a good share of them can never be billed. New Zealand's national public holidays take out eleven weekdays in each of 2026, 2027 and 2028 once the ones that fall on a weekend are moved to the following Monday or Tuesday, and your region's anniversary day takes out one more. Then come your own choices: the weeks of leave you take, the days you expect to lose to illness, and the days that go on running the business, such as quoting, invoicing, bookkeeping and finding the next contract. You choose the year, whether to count an anniversary day, your weeks of leave, sick days, admin days and the hours you bill in a day. The calculator counts the weekdays in that year, takes off the public holidays observed on a weekday using the official dates, including the gazetted date for Matariki, and gives you your billable days, your billable hours and the days you are not billing. The leave, sick and admin figures are your own estimates, so set them to match how you really work, not how you would like to.

Anniversary days are regional and the date varies by region, so they are not in the national holiday list. Choosing yes counts one extra weekday off whichever region you are in.
