Terms of Use

The calculators are informational

Everything on this site is provided for general information and planning. It is not professional advice and should not be treated as a substitute for it.

• Financial tools are not financial, investment, tax, or legal advice. Real loan and investment products carry fees, taxes, and terms that these calculators do not model. Always confirm figures with your lender or a qualified adviser before committing.
• Health tools are not medical advice, diagnosis, or treatment. BMI, body fat, calorie, and pregnancy figures are population estimates that may be wrong for you specifically. Consult a qualified healthcare professional before making health decisions.
• Projected returns are illustrations based on the rate you enter, not predictions. Past performance does not indicate future results, and investments can lose value.

Accuracy

We take accuracy seriously and each calculator states the formula it uses. Even so, the site is provided “as is” without warranties of any kind. We do not guarantee that results are free of error, and we are not liable for any loss arising from reliance on them. Verify anything that matters.

If you find an error, please report it — corrections are made quickly.

Acceptable use

You may use the calculators freely for personal and commercial purposes. You may not scrape the site at a rate that degrades it for others, republish its content wholesale as your own, or attempt to compromise its security.

Intellectual property

The mathematical formulas used here are standard, public, and belong to no one. The site design, written explanations, and code are ours. Quote short passages with attribution and a link; do not copy pages wholesale.

Availability

We aim to keep the site online but do not guarantee uninterrupted availability. Calculators may be added, changed, or removed at any time.

Changes to these terms

These terms may be updated. Continuing to use the site after a change means you accept the revised terms. The date at the top of this page shows when it was last revised.
