Free Calorie & Macro Calculators
Dial in your deficit, not your guesswork. Use our free, science-based calculators to estimate BMR, TDEE, a safe calorie deficit, and precise macros (protein, carbs, fats). Every tool is simple, accurate, and built for sustainable results.
Quick Start
- New here? Start with the Calorie Deficit Calculator to get your daily calories and macros.
- Already tracking? Use TDEE to confirm maintenance, then subtract a safe % to set your deficit.
- Optimizing macros? Jump to Protein, Carb, or Fat calculators to fine-tune targets.
All Calculators
1) Calorie Deficit Calculator
Estimate a sustainable calorie target and macro split based on your body stats, goal pace, and activity.
Use it when: You want a ready-to-follow plan for fat loss.
Open: /calorie-deficit-calculator/
2) TDEE Calculator (Total Daily Energy Expenditure)
Find your true maintenance calories using activity level and (optionally) body-fat % to improve accuracy.
Use it when: You need to confirm maintenance before setting a deficit.
Open: /tdee-calculator/
3) BMR Calculator (Basal Metabolic Rate)
Your resting energy needs based on Mifflin-St Jeor/HB equations; a building block for TDEE.
Use it when: You want to understand the foundation of your energy needs.
Open: /bmr-calculator/
4) Macro Calculator
Turn your calorie target into daily macro grams (protein, carbs, fats) with flexible presets or custom ratios.
Use it when: You know your calories and want an easy macro breakdown.
Open: /macro-calculator/
5) Protein Intake Calculator
Calculate optimal protein based on body weight, goal, and training volume to support satiety and lean mass.
Use it when: You’re hungry in a deficit or want better recovery.
Open: /protein-calculator/
6) Carb Calculator
Set carb ranges for training days vs rest days and manage fiber goals for appetite control.
Use it when: You want energy for workouts while losing fat.
Open: /carb-calculator/
7) Fat Intake Calculator
Establish a healthy minimum and fine-tune fats for hormones, satiety, and preference.
Use it when: You’re balancing taste, fullness, and health.
Open: /fat-calculator/
Tip: After running TDEE, re-run the Calorie Deficit tool at −10–25% depending on timeline and adherence.
How to Use These Tools (3 Steps)
- Find maintenance: Run the TDEE Calculator.
- Set your deficit: Use the Calorie Deficit Calculator (start with 10–20%).
- Lock in macros: Open the Macro Calculator, then adjust with the Protein/Carb/Fat tools.
Smart Defaults (You Can Edit Anytime)
- Deficit range: 10–25% below TDEE
- Protein: 1.6–2.2 g/kg (0.7–1.0 g/lb) body weight
- Fiber: 14+ g per 1,000 kcal
- Re-check: Recalculate after every 4–6 weeks or 2–4 kg lost
FAQs
Are these calculators medical advice?
No. They’re educational tools. If you have a medical condition, consult a professional.
Which calculator should I start with?
Run TDEE to confirm maintenance, then Calorie Deficit, then Macro.
How accurate are the results?
Equations are research-based estimates. Track weight/measurements and adjust by 50–100 kcal as needed.
How often should I update numbers?
Any time your body weight changes by ~2–3% or your activity level shifts.
