Calorie / TDEE calculator
Daily calorie target
2,450kcal
Estimated BMR: 1,750 kcal/day

Calculated using the Mifflin–St Jeor equation, the formula most dietitians consider the most accurate for estimating everyday calorie needs. This is an estimate for general planning, not medical advice.

BMI calculator
Body Mass Index
24.5
Normal weight

BMI is a broad screening measure and doesn't account for muscle mass, bone density, or body composition — treat it as a starting point, not a diagnosis.

Macro calculator
Daily macro split
Protein
245g
Carbs
184g
Fat
82g

Tip: run the Calories tab first, then bring your daily target here to see it split into grams of protein, carbs, and fat.

Body fat % calculator
Estimated body fat
17.2%
Fitness range

Uses the U.S. Navy tape-measure method — measure waist at the navel, neck just below the larynx, and (for women) hips at the widest point. Less precise than DEXA or calipers, but no equipment needed.

Water intake calculator
Daily water target
2.6L
About 11 cups (250ml each)

Baseline of 35ml per kg of body weight, adjusted for exercise and climate. Includes water from food and drinks generally — needs vary by individual and medical conditions.

Race pace predictor
Predicted finish times
5K24:10
10K52:00
Half marathon1:55:30
Marathon4:00:15

Uses the Riegel formula, a standard method for predicting endurance performance across distances from one recent result. Assumes similar training and conditions for both races.

One-rep max calculator
Estimated bench press 1RM
117kg
85% · 90kg    90% · 105kg    95% · 111kg

Estimated using the Epley formula. Each lift gets its own saved weight/reps, so switching between bench, squat, and deadlift won't overwrite your numbers. Accuracy drops for sets beyond ~12 reps.
