Disclaimer

All calculators and guides on Qalkulator are provided for general information and education. Results depend on the values you enter and on the assumptions stated on each page.

Financial and tax calculators

Loan, investment, retirement, salary and tax results are estimates. Lenders, banks, employers and tax authorities apply their own rules, fees and rounding, and tax law changes. Results are not an offer, a quote or financial, tax or legal advice.

Health calculators

BMI, BMR, calorie, body fat and ideal weight results come from population formulas that do not account for every individual. They are not a diagnosis or medical advice. Talk to a doctor or registered dietitian about your health, especially if you are pregnant, under 18, an athlete or managing a medical condition.

Unit conversions and dates

Conversions use exact international definitions and date calculations use the Gregorian calendar. Displayed values are rounded for readability.
