The calculators, converters and written content on CalculatorSphere.com (the “Website”) are provided free of charge for general informational and educational purposes only. Every result the Website produces is an estimate. It is not professional advice, and it is not tailored to your personal circumstances.

General use
- You use the calculators at your sole discretion and at your own risk.
- We build every tool on standard, widely published formulas and test each one against hand-worked examples, but we do not warrant that results are accurate, complete, current, or suitable for any particular purpose.
- We are not liable for any loss or damage, direct or indirect, arising from use of the Website, its tools, or its content.
- The Website links to external resources. We do not control and are not responsible for their content, accuracy, or privacy practices.
Financial calculators
Our loan, EMI, interest, investment, tax, salary, valuation and business calculators are illustrative tools, not financial, investment, tax, accounting or legal advice. We are not certified financial advisors, accountants or tax practitioners, and no result from this Website creates an advisory relationship.
- Assumptions matter. Each financial calculator states the formula and assumptions it uses. Real lenders, tax authorities and institutions apply additional fees, rounding conventions, eligibility rules and day-count methods that our estimates cannot capture.
- Rules change. Tax slabs, statutory rates, contribution limits and price caps are revised periodically. We review rate-dependent calculators when the underlying rules change, but there may be a gap between an official change and our update. Always confirm current figures with the relevant authority before acting.
- Jurisdiction matters. Where a calculator is built for a specific country, that country is named on the page. Do not apply a country-specific tool to another jurisdiction.
- Market values fluctuate. Where a tool asks you to enter a price or rate (for example a gold rate), the accuracy of the result depends entirely on the figure you supply.
Consult a qualified professional before making any financial decision.
Health and fitness calculators
Our health-related tools (including BMI, body composition, hydration, calorie and sleep calculators) are general wellness estimates and not medical advice, diagnosis or treatment. They use population-level formulas that cannot account for your medical history, medication, body composition, pregnancy or any existing condition.
Never disregard professional medical advice or delay seeking it because of something you read or calculated here. If you have a health concern, speak to a doctor or qualified healthcare provider. In an emergency, contact your local emergency services immediately.
Reporting an error
We take formula accuracy seriously. If you believe a calculator returns an incorrect result, please tell us through our Contact page or at support@calculatorsphere.com, including the inputs you used and the result you expected. We investigate every report, correct confirmed errors (typically within a few days), and update the review date on the affected page.
