What Coach Plum calculates

Coach Plum combines several useful body and energy calculations in one free tool. Enter your age, sex used by the formula, height, weight, work activity and weekly exercise. Body-fat percentage is optional, but providing it enables additional body-composition estimates.

Your results include estimated Total Daily Energy Expenditure (TDEE), Basal Metabolic Rate (BMR), Resting Metabolic Rate (RMR), Body Mass Index (BMI), body composition when body fat is supplied, energy targets, macronutrients and an estimated maximum heart rate.

Adjust your result

The results page includes a live energy-target slider from 20% below maintenance to 20% above maintenance, fixed target presets and five selectable Protein / Carbohydrate / Fat macro ratios. You can switch back to the personalised macro estimate at any time.

Calories, kcal or kJ

You can choose whether energy results are displayed as calories, kcal or kJ. Food calories and kcal use the same numerical value; kilojoules are converted at 4.184 kJ per kcal.

Privacy-friendly by design

Calculator inputs are processed in your browser. New calculations use temporary per-tab session storage to carry your inputs to the results page and do not store them in an application database.
