Disclaimer

The calculators and articles on Reliable Calculator are designed to help you understand numbers and explore scenarios. Please keep the following in mind.

Financial calculators

Loan, mortgage, savings and investment results are estimates. Lenders may calculate interest differently, round payments, or include fees and insurance that our tools do not know about. Investment returns are never guaranteed, and past performance does not predict future results. Speak to a licensed financial adviser before making investment or borrowing decisions.

Health calculators

BMI, calorie, body fat, heart rate and pregnancy tools use population-based formulas that may not reflect your individual body. They are not a diagnosis and are not a substitute for medical advice. Talk to your doctor, midwife or a registered dietitian about your health, especially if you are pregnant, have a medical condition or take medication.

Other tools

Date, conversion and math tools are tested carefully but may contain errors. For legal deadlines, engineering, medicine dosing and other critical uses, verify results independently.
