## All calculators

- [BMI Calculator with Body Fat Estimate (kg and lbs)](https://www.recompai.com/tools/bmi): Calculate your BMI from height and weight in seconds. See your category, the formula in kg and lbs, and what the number actually says about body composition.
- [BMR Calculator: Basal Metabolic Rate and Calories](https://www.recompai.com/tools/bmr): BMR calculator with the Mifflin-St Jeor equation (men +5, women -161) and Katch-McArdle from body fat. Use it to set your calorie floor for a cut or recomp.
- [Body Fat Percentage Calculator (Navy, Skinfold, Visual)](https://www.recompai.com/tools/bodyfat): Calculate body fat percentage with Navy tape, skinfolds, or a visual estimate, then use it to guide a cut, bulk, or recomposition plan.
- [Lean Body Mass Calculator: LBM from Body Fat %](https://www.recompai.com/tools/lbm): Calculate lean body mass from weight and body fat percentage. Use LBM to set protein, compare BMR estimates, and follow your lean-mass estimate through a cut.
- [Macro Calculator: Calories, Protein, Fat and Carbs](https://www.recompai.com/tools/macros): Calculate daily calories, protein, fat, and carbs from your goal, activity, and body composition.
- [Protein Intake Calculator: Grams per Day (g/kg)](https://www.recompai.com/tools/protein): Calculate daily protein grams from weight, body fat, goal, activity, and experience. See per-meal targets and where your number sits in the research range.
- [TDEE Calculator: Total Daily Energy Expenditure and Maintenance Calories](https://www.recompai.com/tools/tdee): Calculate TDEE from weight, height, age, sex, and activity level. Your maintenance calorie anchor for fat loss, recomposition, and lean muscle gain.
- [Waist-to-Height Ratio Calculator + Chart (WHtR)](https://www.recompai.com/tools/waist-height-ratio): Calculate waist-to-height ratio, read the 0.5 cutoff, and see how WHtR tracks abdominal fat and metabolic risk better than BMI alone.
- [Waist-to-Hip Ratio Calculator: Visceral Fat and Risk](https://www.recompai.com/tools/waist-hip-ratio): Calculate your waist-to-hip ratio and see where fat distribution, not just body weight, puts your cardiometabolic risk. Sex-specific WHO thresholds, a pooled mortality curve, and a waist reference based on your hip measurement.
- [Water Intake Calculator: Daily Water Intake](https://www.recompai.com/tools/water-intake): Calculate daily water intake from weight, sex, activity, and climate. Get liters per day, a drinking schedule, and hydration checks for training.
- [Weight Loss Calculator: Calorie Deficit, 7,700 kcal per kg](https://www.recompai.com/tools/weight-loss): Plan a calorie deficit with the 7,700 kcal per kg rule: daily calorie target, pace and timeline, and where the NIH Body Weight Planner diverges on long cuts.
