Terms of Service

Effective Date: December 27, 2025

Welcome to Qwerty Calculators. These Terms of Service ("Terms") govern your use of our website and calculator tools. By accessing or using Qwerty Calculators, you agree to be bound by these Terms.

We've written these Terms to be clear and readable — not to hide anything in legal jargon.

Qwerty Calculators offers free online calculator tools for various purposes:

• Financial calculations — Percentages, compound interest, tips, and more
• Health and fitness — BMI, calorie estimates, and related tools
• Date and time — Age calculations, countdowns, time conversions
• General utilities — Random number generation and other helpful tools

All our calculators use standard, well-documented formulas. We explain the methodology on each calculator's page so you can understand and verify how results are calculated.

This is the most important section of these Terms. Please read it carefully.

Our calculators are provided for informational and educational purposes only. They are designed to help you with quick estimates, general planning, and understanding how different calculations work.

Not Financial Advice — Our financial calculators are not a substitute for professional financial advice. Do not rely solely on our tools for investment decisions, tax planning, loan decisions, or retirement planning. Consult a qualified financial advisor for advice specific to your situation.

Not Medical Advice — Our health-related calculators provide general estimates based on population-level formulas. They do not account for your individual health conditions, medical history, or body composition. Always consult a qualified healthcare professional before making health-related decisions.

Not Legal or Tax Advice — If any calculation has legal, regulatory, or tax implications, verify the results with appropriate professionals.

Your Responsibility — You are solely responsible for how you use the results from our calculators. Use our tools as a starting point, not the final word.

Our Commitment

• Using standard, well-documented formulas
• Clearly explaining our methodology
• Regularly reviewing and updating our tools
• Welcoming error reports from users

Our Limitations

• No calculator is perfect. Errors may occur.
• Formulas are based on general assumptions that may not apply to your situation.
• Results are only as accurate as the information you input.
• Some calculations involve inherent limitations (e.g., BMI doesn't account for muscle mass).

If You Find an Error — Contact us at qwertycalculators@gmail.com. We take accuracy seriously and will investigate promptly.
