Terms of use
Last updated: 2 September 2026
By using oneand.in you agree to these terms. If you do not agree, do not use the calculators.
Estimates, not advice
Output is an educational estimate of commonly used India private-salary formulae. It is not tax advice, legal advice, accounting advice, or a substitute for a chartered accountant, your employer, the Income Tax Department, or EPFO. Laws, slabs, labour codes and exemption limits change.
No warranty
The site is provided “as is”. We do not warrant completeness, accuracy, or fitness for a particular offer letter, Form 16, or gratuity settlement. You remain responsible for filings and negotiations.
Acceptable use
Do not scrape in a way that degrades the service, impersonate One & Done, or republish calculator output as certified advice. You may link to our pages.
Intellectual property
The 1& mark, One & Done name, and original copy on this site are used for the oneand.in project. Do not copy the tools as a competing property with the same brand.
Limitation of liability
To the extent permitted by law, we are not liable for indirect or consequential loss, including extra tax, lost offers, or delayed gratuity, arising from use of the site.
