Common Questions
How accurate are your TDEE and calorie calculators? ▾
All calculators use peer-reviewed equations — the Mifflin-St Jeor formula for TDEE, the Katch-McArdle formula for lean-body-mass TDEE, and the US Navy method for body fat. Accuracy varies ±5–10% for individuals; for clinical use, consult a registered dietitian.
Is my data private? Do you store my inputs? ▾
All calculations happen 100% in your browser. We do not transmit, store, or sell any biometric data you enter. Your stats persist only in your browser's localStorage and are never sent to our servers.
Can I suggest a new calculator or feature? ▾
Absolutely — select "Feature Request" in the form above. We genuinely read every submission. Many tools in TDEEmacro (like the GLP-1 and Postpartum calculators) came from user suggestions.
