Before relying on the estimate
Questions this calculator cannot decide alone.
What does this ACC calculator cover?+
Standard CoverPlus for a self-employed person. It does not include CoverPlus Extra, employer levies, shareholder-employee treatment or experience-rating adjustments.
Why can the income used be higher than I entered?+
ACC applies minimum liable earnings to full-time self-employed people. The tool uses the current full-time minimum where that setting is selected.
Where do I find my Work rate?+
Check MyACC or the industry and rate shown on your latest ACC invoice. Use the custom-rate option if your occupation is not listed.
