TDEE Calculator is a collection of small tools for understanding everyday calorie and nutrition estimates.
What we care about
A useful result should be quick to find, easy to understand and honest about what it cannot tell you. That means visible formulas, clear assumptions, realistic limitations and no account requirement.
A toolkit that works together
Start with daily energy, explore your calorie and protein targets, compare resting-energy equations, and use your journal to observe changes over time. Calculator details are saved only when you opt in, and journal entries stay in your browser.
Health information, with context
These tools are for general information. They do not diagnose health conditions or replace a clinician or registered dietitian. We do not claim medical review or invent expert credentials. The methodology page lists our equations, planning rules and references.
