Example Calculation with the Active Metabolic Rate Calculator (TDEE)

Imagine that your Basal Metabolic Rate is 1,700 kcal and your activity level is moderate (factor 1.55).
📐 Applied formula: TDEE = 1.700 × 1.55
📊 Result: 2,635 kcal per day
This means you need to consume approximately 2,635 calories a day to maintain your current weight with your activity level.
📢 Adjust your diet or exercise plan based on this key information.

How Does Our Active Metabolic Rate Calculator Work?

Our calculator follows a simple three-step process:

1️⃣ Data Entry
BMR 📊 Your basal metabolic rate, previously calculated or estimated by another tool.
Activity level 💪 Choose between sedentary, light, moderate, intense, or very intense.

Why is it important?
This data accurately determines your actual daily energy expenditure, allowing you to make better nutritional and fitness decisions.

2️⃣ Automatic Calculation
We use the formula:
📐 TDEE = BMR × Activity Factor
The result will give you the estimated number of calories needed to maintain your weight with your current activity level.

3️⃣ Results and Recommendations
🔹 If the result is high, you can adjust your diet to lose weight.
🔹 If the result is low, you can increase your intake if you want to gain muscle mass.

Do you need to know the TMB beforehand?
Yes, you can calculate it with our TMB calculator or enter the value directly.

What happens if I underestimate my physical activity?
You will get a lower TDEE, which can lead to an insufficient diet.

What happens if I overestimate my physical activity?
You could consume more calories than necessary and gain weight.

Is it useful for increasing muscle mass?
Yes, you can establish a caloric surplus based on your TDEE.

Should I recalculate my TDEE if I lose weight?
