Plan Snapshot

Why this calculator?

  • Uses Mifflin-St Jeor (most accurate in 2026 studies)
  • Activity multipliers updated for hybrid work schedules
  • Goal slider applies realistic surplus/deficit percentages
  • Protein defaults to 2 g/kg — adjustable per training style

What if I track in pounds?

Multiply weight in pounds by 0.453 to convert to kg, or use 1 kg ≈ 2.205 lb.

Protein too high?

Most lifters thrive between 1.6-2.4 g/kg. Reduce the slider if digestion or budget suffers.

How often should I recalc?

Every 4 weeks or after a 5+ lb body change. Activity or job shifts also matter.

Fasting or OMAD?

Split macros into fewer meals — the calculator still shows total daily targets.

Frequently Asked Questions

What is a TDEE calculator?

TDEE (Total Daily Energy Expenditure) is your maintenance calorie level. It equals your BMR multiplied by an activity factor ranging from 1.2 (sedentary) to 1.9 (very active).

What is a calorie calculator?

To lose 1 lb/week, eat 500 fewer calories per day than your TDEE. To gain 1 lb/week, eat 500 more. Our calculator personalizes targets for your body and goal.

What is a protein calculator?

For muscle building, aim for 0.7–1g of protein per pound of bodyweight. For weight loss, higher protein (0.8–1g/lb) preserves muscle while cutting calories.
