Financial & Medical Disclaimer

General Disclaimer

elCalculador provides free calculation tools covering finance, health, science and lifestyle topics. Every calculator is built on standard, published formulas and is intended purely for general informational and educational purposes. Nothing on this site is personalized advice, and no calculator result should be treated as a final, authoritative figure for a real-world decision.

You are solely responsible for verifying any result before relying on it, and for seeking qualified professional advice appropriate to your specific situation.

⚖️ Financial & Tax Disclaimer

Our mortgage, loan, VAT/tax, budget, margin and sales calculators use standard, textbook financial formulas (such as the fixed-rate amortization formula and standard cost-accounting ratios). They do not account for lender-specific fees, local regulations, promotional rates, currency fluctuations or changes in tax law.

Tax rates and thresholds referenced or implied by our tools vary by country and change over time. For an authoritative figure, consult a licensed accountant, financial advisor, mortgage broker, or your national tax authority — for example the AEAT (Agencia Tributaria) and the BOE (Boletín Oficial del Estado) in Spain, the SAT (Servicio de Administración Tributaria) in Mexico, the IRS in the United States, or HMRC in the United Kingdom. elCalculador is not affiliated with any of these bodies and does not provide tax filing or legal services.

⚕️ Medical & Health Disclaimer

Our calorie, BMR/TDEE and related health-adjacent tools use established public formulas (such as the Mifflin-St Jeor equation) to produce general estimates. They are not medical devices, do not constitute medical advice, and cannot account for your full medical history, medications, or individual physiology.

Always consult a physician, registered dietitian or other qualified healthcare provider before making decisions about diet, exercise, weight management or any health condition — particularly if you are pregnant, nursing, elderly, an athlete with specific needs, or managing a chronic illness. If you are experiencing a medical emergency, contact your local emergency services immediately.

Privacy & Data

All calculations run client-side, directly in your browser. Numbers you enter into any calculator — property prices, incomes, body measurements, or anything else — are never transmitted to or stored on our servers. See our full Privacy Policy for details on analytics and advertising cookies.

No Warranty & Limitation of Liability

elCalculador is provided "as is" without warranties of any kind, express or implied. While we manually verify our formulas (see our Editorial Methodology), we do not guarantee that results are free of errors, omissions or rounding differences. To the fullest extent permitted by law, elCalculador and its operators are not liable for any loss or damage arising from reliance on any calculator's output.
