Is MyFitnessPal Accurate? TDEE Calculator vs MyFitnessPal
MyFitnessPal is a food-logging app that also sets a calorie goal; a TDEE calculator only sets the target, but shows how it is built. The two answer different questions: how much to eat, and how much was eaten. This page compares them on that split.
8 criteria. Published Apr 2, 2026. Updated Oct 19, 2026. By AI Fit Hub.
A purpose-built calculator that runs several BMR equations, shows the spread between them and turns the result into goal-specific targets with the math visible.
Pros
- Runs multiple formulas (Mifflin-St Jeor, Harris-Benedict, Katch-McArdle, WHO/FAO) and shows all results
- Shows the confidence range so you know how certain the estimate is
- Goal-specific outputs (cut/maintain/bulk) with direct macro calculator integration
- Weekly training/rest day breakdown for variable schedules
- 100% transparent — you see every formula and can verify the math
Cons
- Only calculates the target — doesn't track food intake
- Requires manual entry of the target into a tracking app
- No food database or barcode scanning
Setting an accurate calorie target before you start tracking, recalibrating every 4-6 weeks, understanding the math behind your numbers
A food-logging app with a large food database and barcode scanning, plus its own calorie goal from your profile and activity level.
Pros
- Integrated food logging with a large food database
- Barcode scanner for packaged foods
- Social features and recipe logging
- Exercise calorie integration (syncs with wearables)
Cons
- The calorie goal's inputs are shown, but the app is built for logging rather than for comparing estimation methods
- Broad activity levels, like any multiplier-based estimate
- Exercise calorie additions often cause people to 'eat back' burned calories, stalling progress
- A fixed weekly-loss setting does not adapt to how your weight actually responds
- Some features sit behind a paid subscription
Daily food logging, meal planning, barcode scanning convenience — once you have a validated calorie target from a dedicated calculator
Decision table
See the tradeoffs side by side
| Criterion | Dedicated TDEE Calculator (AI Fit Hub) | MyFitnessPal Built-in Goal |
|---|---|---|
| Formula transparency | Full — shows all formulas used | Calorie goal shown; method details less prominent |
| Number of formulas | 3-4 with range | One goal |
| Food tracking | No | Yes |
| Barcode scanning | No | Yes |
| Goal targets | Cut/maintain/bulk with custom deficit | A chosen weekly loss rate |
| Training day adjustment | Yes (weekly breakdown) | Only via exercise logging |
| Price | Free | Free tier plus a paid subscription |
| Privacy | No account, no data sent | Account required, data stored on servers |
Verdict
Use both — they solve different problems. Calculate your TDEE with a dedicated calculator to get an accurate, transparent calorie target. Then use MyFitnessPal (or Cronometer, MacroFactor, etc.) to track whether you are hitting that target. Don't rely on MFP's built-in calorie goal as your source of truth — it's a convenience feature, not a calibrated estimate.

Questions people ask next
Why does MyFitnessPal give me a different calorie target than the TDEE calculator?
Calculators and apps can differ in the BMR equation, the activity multipliers and how exercise is counted. A TDEE calculator folds your training into the activity level; a logging app may set a lower base goal and add logged exercise on top. Either way, check the target against two to three weeks of weight change and adjust.
Should I eat back exercise calories in MFP?
If your target already includes your training through the activity level, no: the calories are already counted. If the app's base goal assumes little activity and you log workouts separately, eating back only part of them is a cautious choice, because device estimates of exercise energy are often well off (Shcherbina 2017).
Are there better alternatives to MyFitnessPal for food tracking?
Cronometer is more accurate for micronutrient tracking and uses verified database entries. MacroFactor uses an adaptive TDEE algorithm that learns from your weight trend data. Both pair well with a dedicated TDEE calculator for setting your initial target.
