Educational Use Only

The calculators, content, and explanatory text on MSO Calc are provided for educational and informational purposes only. They are not a substitute for professional financial, tax, legal, medical, fitness, or other expert advice tailored to your specific situation. Always consult a qualified professional — financial advisor, tax preparer, attorney, doctor, etc. — before acting on any number or recommendation produced here.

Calculator Results May Contain Errors

We work carefully to implement standard formulas correctly and test the calculators against known reference values. However, results may still contain errors due to:

• Software bugs we haven't found yet
• Rounding and floating-point precision limits inherent to JavaScript
• Simplifications of complex real-world formulas (e.g. tax brackets that change, regional variations we don't model)
• Inputs that are mistakenly entered, mis-keyed, or copied incorrectly
• Browser-specific bugs or extensions interfering with execution

Always sanity-check important numbers using an alternative source (another calculator, a spreadsheet, a professional). Treat MSO Calc results as a quick estimate or learning tool — not as a definitive figure.

Not Legally Binding

No result on this site is a legally binding figure. Mortgage payment estimates are not loan offers. Tax estimates are not tax returns. Investment projections are not promises of return. Pregnancy due dates are not medical diagnoses. The numbers are useful starting points for planning; they are not contracts, prescriptions, or guarantees of any kind.

Past Performance / Assumptions

Financial calculators that project growth (compound interest, retirement, investment return) rely on assumptions you provide about future returns, inflation rates and contribution levels. Past performance does not guarantee future results. Markets, tax laws, inflation rates and personal circumstances change. A projection is one possible scenario, not a forecast.

Health and Fitness Disclaimer

BMI, BMR, calorie, body-fat and similar calculators provide rough population-level estimates. They cannot replace personalized advice from a doctor or registered dietitian. If you are pregnant, elderly, very lean, very muscular, have any medical condition, or are starting a new diet or exercise program, consult a healthcare professional first.

Currency Rates

The currency converter uses live rates from a third-party API. Real exchange rates available at banks, ATMs and currency exchanges will differ (typically by 1-4%) due to spreads and fees. Do not use figures from this site to commit to a financial transaction.

No Liability

By using MSO Calc, you agree that we, the site operators, are not liable for any losses, damages, decisions or consequences arising from your use of (or inability to use) the calculators or content. The site is provided "as is" with no warranties of any kind. See our Terms of Use for the full legal language.

Report Errors

If you spot a math error, a misleading explanation, or a bug in any calculator, please report it via the contact page. We take corrections seriously and prioritize math errors.
