Frequently Asked Questions
What is Calorique?
Calorique is a free suite of 24 health and fitness calculators that run entirely in your browser. Calculate BMI, TDEE, macros, body fat, calories burned, fitness age, and more — all using science-backed formulas like Mifflin-St Jeor and Harris-Benedict.
Are the calculators accurate?
Yes. All calculators use peer-reviewed formulas from established medical and sports science research. Results are estimates — individual metabolism varies, so consult a healthcare professional for personalized advice.
Is my health data private?
Calculator math runs client-side in your browser using JavaScript. Your weight, height, age, and other calculator inputs are not saved to a Calorique account or health-input history database. Ordinary site analytics, consent, advertising, security, and hosting signals are covered by the Privacy Policy.
Which calculator should I start with?
Start with the TDEE Calculator to find your Total Daily Energy Expenditure, then use the Macro Calculator to set protein, carb, and fat targets for your goal.
