Terms of use
Using this site means accepting these terms. They are short, and the only one that really matters is the second.
Free to use
Every calculator here is free, needs no account and has no usage limit. You are welcome to use the results in your own work, quote them, or link to any page.
What you may not do is scrape the site wholesale to republish it, or present these tools as your own.
No warranty of accuracy
These tools are provided as they are. We check every formula and every published rate, and we still cannot warrant that a result is accurate, current or fit for your particular purpose.
You remain responsible for verifying anything you rely on, particularly where a figure comes from an authority that may have revised it since the date shown on the page.
Limitation of liability
To the extent the law allows, we are not liable for loss arising from use of this site or reliance on any result it produces.
Nothing in these terms excludes rights you have under the Australian Consumer Law or the New Zealand Consumer Guarantees Act that cannot lawfully be excluded.
External links
Pages here link to government and standards bodies so you can check a figure at its source. Those sites are not ours, and their content and availability are not something we control.
Changes
These terms may change. The version on this page is the one that applies, and material changes will be reflected here rather than announced separately.
