Daily Calorie Estimates

The results show a number of daily calorie estimates that can be used as a guideline for how many calories to consume each day to maintain, lose, or gain weight at a chosen rate.

  • Maintain weight
  • Mild weight loss (0.25 kg/week)
  • Weight loss (0.5 kg/week)
  • Extreme weight loss (1 kg/week)

How to Use the Calorie Calculator?

Enter your age, weight, height, activity level, and goals into the Calorie Calculator and it will provide you with the daily calorie target you need to lose, maintain, or gain weight. You can always edit the inputs to receive different results.

Daily Calorie Needs for Health

Calorie needs vary based on age, weight, height, sex, health status, and activity level. For example, a tall, active 25-year-old man might need 2,000–3,000 calories, while women typically need 1,600–2,400. Eating too few calories (below 1,200 for women or 1,500 for men, unless supervised) can affect basic bodily functions. Adjust intake to meet your health and weight goals.

Practical Applications

  1. Plan daily meals to meet weight loss or maintenance targets.

  2. Use with our BMI Calculator to monitor progress.

  3. Experiment with different activity levels to optimize calorie needs.

FAQ

How many calories should I eat to lose weight?

If you want to lose weight, all you have to do is enter your details into the Calorie Calculator and select the weight loss goals. This will guarantee that you will get a daily target below the maintenance level which generally is around 500 to 1000 calories a day for safe weight loss.

What is a calorie deficit calculator?

This is a tool that estimates the calories you will need to eat each day to shed extra weight. In a more precise definition a calculator will determine a number lesser than what the body burns, and by consuming this between meals will help gradually shed fat.

How to calculate maintenance calories?

With the Calorie Calculator, all you have to do is plug in your age, weight, height, and activity level, and it will automatically tell you the exact amount of calories needed for maintaining your current weight without gaining or losing it.

Why use a calorie intake calculator?

Using a calorie intake calculator is helpful in meal planning by estimating you daily requirement based on individual circumstances based on your dietary goals. CalcMate's calculator provides custom results to help you stay on track with your nutrition plan to lose, gain, or maintain weight.

What formulas are used in the Calorie Calculator?

The most significant formula used in CalcMate's Calorie Calculator is the Mifflin-St Jeor Equation, which will allow us to calculate your Calorie Basal Metabolic Rate (BMR) according to your age, weight, height and gender. The BMR will subsequently be adjusted through an activity multiplier between 1.2-1.9 according to the level of physical activity, thus then producing custom Total Daily Energy Expenditure (TDEE) for you to achieve your calorie goals. This formula has been accepted by the American Dietetic Association for accuracy in nutritional counseling.

Can the Calorie Calculator assist with meal planning?

Yes, the Calorie Calculator estimates your daily calorie needs, which can be divided across meals and snacks to align with your dietary goals. For balanced nutrition, distribute calories based on protein, carbs, and fats, and consult a registered dietitian for tailored meal plans.

Does the Calorie Calculator consider medical conditions?

The Calorie Calculator is based on standard equations such as Mifflin-St Jeor and do not consider medical conditions (for example, diabetes or thyroid dysfunction). If you have calorie needs related to your health status, please talk to your health care provider or dietitian, so that you are safely and accurately planning your needs.
