Disclaimer
The short version: the calculators on this site provide information, not advice. Use the numbers as a starting point, not a final decision.
Information, not advice
Every calculator on Calculator.org.nz is a tool for working out a number based on the inputs you provide. Nothing on this site constitutes financial advice, tax advice, legal advice, mortgage advice, insurance advice, or investment advice as defined under New Zealand law.
No relationship is formed by use
Using a calculator on this site does not create a client relationship between you and the operators of Calculator.org.nz. We do not know your full circumstances and we are not authorised to advise you on them.
Accuracy of rates and rules
We do our best to keep tax brackets, ACC levies, KiwiSaver tiers, RBNZ thresholds, and other NZ-specific rules current to the most recent published rates. Even so:
- Rates change. The site is reviewed quarterly, but a recent IRD change may not yet be reflected.
- Calculators simplify. Real-world calculations sometimes have edge cases, transitional rules, or one-off adjustments that the calculator does not handle.
- Edge cases may be missing. If you sit at the threshold of a bracket, in a complex employment situation, or operate via multiple entities, a calculator's number is approximate.
Always check with a qualified professional
Before making a decision that depends on the numbers, especially around mortgages, tax obligations, KiwiSaver withdrawals, insurance cover, or business structure, talk to a registered NZ professional. That includes:
- A registered financial adviser for KiwiSaver, investment, and retirement planning.
- A chartered accountant or registered tax agent for tax planning, GST, and FBT.
- A mortgage adviser or your bank's lending team for borrowing decisions.
- An insurance broker or adviser for cover decisions.
Use of the site
To the maximum extent permitted by law, the operators of Calculator.org.nz exclude liability for any loss or damage arising from reliance on the calculators or the explainer prose attached to them. You use this site at your own discretion.
External links
Where the site links to external resources (IRD pages, RBNZ announcements, sponsor websites), we do not control or guarantee the content of those external pages. Always confirm the most recent published rules with the source authority.
