Terms
By using this site you accept the terms below. They are intentionally short and written to be readable.
Results are estimates
The calculators are provided for general information and education. Results depend entirely on the values you enter and on stated assumptions, and they may not reflect your actual situation, local rules, taxes, or fees.
Nothing on this site is financial, medical, legal, tax, or other professional advice, and no relationship of that kind is created by using it.
No warranty and limitation of liability
We work hard to keep every formula correct and test them automatically, but the site is provided “as is” without warranties of any kind. We do not accept liability for any loss arising from decisions made on the basis of a result shown here.
Always verify important figures independently before acting on them.
Acceptable use and content
You may use the calculators freely for personal and commercial purposes. Please do not attempt to disrupt the service or misrepresent results as professional advice from us.
The text, design, and code of this site remain the property of their authors. These terms may be updated, and the current version always applies.
