Frequently Asked Questions

Are the financial calculators accurate?
Yes, our financial calculators use industry-standard formulas and mathematical models that are accurate for general financial planning and decision-making. They are based on the same formulas used by banks, financial advisors, and accounting professionals. However, for major financial decisions like mortgages, investments, or tax planning, we always recommend consulting with a qualified financial professional who can consider your specific circumstances, local regulations, and personalized advice.
Is the BMI calculator medically accurate?
The BMI calculator uses the standard BMI formula (weight in kg / height in m²) recognized by the WHO, CDC, and other major health organizations worldwide. However, BMI is just one health metric and has limitations - it doesn't account for muscle mass, bone density, age, or sex differences. Athletes and muscular individuals may have high BMI despite being healthy. For comprehensive health assessment, consult healthcare professionals who can evaluate multiple factors including body composition, fitness level, and medical history.
Do I need to create an account?
No account, registration, or sign-up needed! All calculators are completely free to use without providing any personal information. We don't require email addresses, phone numbers, or create user profiles. Simply visit the calculator, enter your values, get instant results, and leave - no strings attached. Your privacy is important to us, which is why we keep everything anonymous and hassle-free.
Can I save my calculations?
Currently, calculations are not automatically saved to protect your privacy and keep the tools simple to use. We recommend copying important results to your notes app, taking screenshots, or writing down the values you need. For financial calculations, many users keep a spreadsheet of results over time. This approach ensures your financial data stays completely private and under your control rather than stored on external servers.
Which calculator is most used?
The Percentage Calculator is our most popular tool, used for everything from calculating discounts to determining grade percentages. The Loan Calculator and Compound Interest Calculator are also extremely popular among people planning mortgages or investments. The BMI Calculator, Date Difference Calculator, and Tip Calculator round out our top tools, each serving thousands of users daily across different use cases from health tracking to everyday math.
