What it does – The Daily Calorie Needs Calculator estimates how many kilocalories you must consume each day to keep your current weight, based on gender, weight, height, age, and activity level. Why it matters – Knowing your maintenance calories lets you set a realistic target for weight loss, gain, or maintenance without guesswork. How to read the result – The number shown is the total calories your body uses on an average day. If you want to lose weight, subtract 500 kcal for a safe weekly loss; to gain, add 250‑500 kcal. The calculator applies the standard activity‑factor multipliers (1.2, 1.375, 1.55, 1.725, 1.9) to your basal estimate, then returns the daily total instantly and for free. Use the figure to portion meals, schedule snacks, and track progress in any nutrition app.
Pro tips
- Round the result to the nearest 50 kcal for easier meal planning.
- If you’re very active, choose the activity factor that matches your typical weekly workouts.
- Use the same units (kg, cm) each time to keep results consistent.
- Avoid adjusting the number for short‑term diet tricks; stick to the baseline for accurate tracking.
