Terms of Use
Rules for using the calculator and website content.
Last updated: 18 September 2026
1. Informational service
The calculator and articles are provided for general information and personal planning. They are not a payroll statement, employment contract, tax return or financial advice.
2. Accuracy
Reasonable care is taken with published inputs and calculations, but rates, thresholds, pay agreements and personal circumstances can change. No guarantee is given that an estimate will match your payslip.
3. Official sources
Where a matter depends on an employment term, pay circular or legal rule, consult the relevant official source. Start with the sources page.
4. External links
External links are provided for reference. The site operator does not control third-party content or availability.
5. Acceptable use
Do not misuse the site, attempt to disrupt its operation, or use estimates as a substitute for required professional or payroll checks.
6. Changes
The site and these terms may be updated when the calculator, data or legal requirements change. The latest published version applies to future use.
