FitCalc vs MyFitnessPal: Fitness Calculators Compared (2026)
FitCalc and MyFitnessPal are often mentioned in the same breath, but they do fundamentally different things. FitCalc is a calculator suite — you come in, get your TDEE, macros, or 1RM estimate, and leave with a number to work with. MyFitnessPal is a daily tracker — you log every meal, every workout, every day. Think of FitCalc as the tool that tells you your targets, and MyFitnessPal as the diary where you track whether you hit them.

The Verdict
These tools complement each other rather than compete. Use FitCalc to calculate your TDEE, set your macro targets, and figure out your training zones — then use MyFitnessPal to actually log whether you hit those targets each day. Neither replaces the other. If you only want quick calculations without creating an account, FitCalc is all you need. If daily tracking and food logging matter to you, MyFitnessPal is the better fit there.
Frequently Asked Questions
Can FitCalc replace MyFitnessPal?
For calculations, yes. For daily food logging and calorie tracking history, no. FitCalc tells you your targets; MyFitnessPal helps you track whether you hit them.
Is MyFitnessPal free?
MyFitnessPal has a free tier with core features. Their Premium plan runs $19.99/month or $79.99/year and removes ads, adds macro tracking detail, and unlocks food analysis features. FitCalc is fully free with no premium tier.
Does FitCalc store my health data?
No. All calculations happen in your browser. Your weight, height, age, and other inputs are never sent to any server. For an app like MyFitnessPal that's built around storing your food diary, data collection is inherent to the product.
Which is more accurate for TDEE?
FitCalc gives you more formula options (Mifflin-St Jeor, Harris-Benedict, Katch-McArdle) so you can pick what's most appropriate for your situation. MyFitnessPal uses a single formula. Both are estimates — TDEE calculation from any formula has roughly ±10% real-world variance.
