General information only
The calculators, results, and written material on Plain Calculators (the “Site”) are provided for general informational and educational purposes only. They are offered on an “as is” and “as available” basis, without warranties of any kind, express or implied, including but not limited to accuracy, completeness, fitness for a particular purpose, or non-infringement.
No professional advice
Nothing on this Site constitutes professional advice, and no calculator is a substitute for a qualified professional:
- Financial tools (such as the Dividend Calculator) are not financial, investment, tax, or accounting advice. Projections are illustrations based on the assumptions you enter and do not predict actual returns. Consult a licensed financial professional before making money decisions.
- Health tools (such as the A1C Calculator) are not medical advice, diagnosis, or treatment. Estimated figures are educational and can differ from laboratory results. Always consult a qualified healthcare provider about your health and before making any medical decision.
- Academic and payroll tools (such as the Weighted Grade and Hour Calculators) provide estimates only; defer to your institution’s or employer’s official figures and policies.
Accuracy and errors
While we make every reasonable effort to keep formulas and results correct, we do not guarantee that the Site is free of errors, and figures may be affected by rounding, input mistakes, or software issues. Always double-check important results independently before relying on them.
Limitation of liability
To the fullest extent permitted by law, Plain Calculators and its operators shall not be liable for any loss or damage — including, without limitation, direct, indirect, incidental, or consequential loss — arising from your use of, or reliance on, the Site or any result it produces.
External links
The Site may link to third-party websites for convenience. We do not control and are not responsible for their content, accuracy, or practices.
