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)

  1. Find maintenance: Run the TDEE Calculator.
  2. Set your deficit: Use the Calorie Deficit Calculator (start with 10–20%).
  3. 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.
