Terms of Use

By using Calculators you accept these terms. They are short because the site does little: it computes numbers from values you provide and explains them.

Educational information only. Every calculator, result, explanation, status and recommendation on this site is general information. Nothing here is financial, investment, legal, tax, insurance, immigration or medical advice, and nothing here creates a professional relationship of any kind.

Estimates, not quotes. Results are estimates produced by applying the stated formulas to the values you enter. Real costs, rates, taxes, fees and prices differ by country, provider and date. Verify anything important with an official source or a qualified professional before acting on it.

Your responsibility. You are responsible for the values you enter and for the decisions you take. We are not liable for any loss arising from reliance on a result, including lost savings, missed deadlines or costs incurred.

Availability. The site is provided as it is, without warranty that it will be available without interruption or free of error. Calculators and pages may be changed, added or withdrawn at any time.

Embedding. You may embed a calculator using the snippet provided on its embed page, including on a commercial site, provided the attribution link back to this site is kept intact and visible. You may not rehost, resell or present the calculators as your own work.

Acceptable use. Automated access that degrades the service for other visitors, attempts to extract the catalog in bulk, and any attempt to interfere with the site or its security are prohibited.

Intellectual property. The calculators, their explanations and the written guides are the property of this site. The formulas themselves are standard public mathematics and are not claimed.
