What is the BMR Calculator?

Our Basal Metabolic Rate (BMR) Calculator helps you estimate the number of calories your body needs daily based on your age, height, weight, and activity level. Whether you want to lose weight, gain muscle, or maintain your current physique, knowing your BMR is the first step to managing your nutrition effectively.

How Does the BMR Calculator Work?

1. Basal Metabolic Rate (BMR) Formula

The BMR formula calculates the number of calories your body burns at rest—the energy required for essential functions like breathing, circulation, and cell production.

2. Harris-Benedict Formula

To get a more accurate estimate of your total daily calorie needs, we apply the Harris-Benedict Formula. This method multiplies your BMR by your activity level to determine your Total Daily Energy Expenditure (TDEE)—the number of calories you need based on how active you are.

Why is BMR Important?

✔️ Helps with weight management – Understand how many calories you need to lose, gain, or maintain weight.

✔️ Supports fitness goals – Tailor your diet and workout plan based on your caloric needs.

✔️ Accurate & science-backed – Uses proven formulas to calculate energy expenditure.

Who Should Use the BMR Calculator?

✅ Individuals tracking their daily calorie intake

✅ Athletes and fitness enthusiasts optimizing nutrition and performance

✅ Anyone planning a weight loss or muscle gain journey

Important Notes

🔹 The calculator does not account for lean body mass (muscle vs. fat ratio), so results may be slightly off for very muscular individuals (underestimated) or those with high body fat (overestimated).

🔹 Use this as a starting point, and adjust based on your progress and body’s response.
