Estimate your daily calorie burn at rest with our BMR calculator.
| Activity Level | Calorie |
|---|---|
| Sedentary: little or no exercise | |
| Exercise 1-3 times/week | |
| Exercise 4-5 times/week | |
| Daily exercise or intense exercise 3-4 times/week | |
| Intense exercise 6-7 times/week | |
| Very intense exercise daily, or physical job |
Simply put in your age, gender, height, and weight, select your preferred unit of measure (metric or imperial) and click calculate to get your basal metabolic rate which displays the calories burnt.
BMR is the minimum calories your body needs to function. Factors like increased muscle mass from weightlifting can raise it, while age or inactivity may lower it. Other influences include diet (e.g., caffeine), pregnancy, frequent small meals, or extreme temperatures. Malnourishment can reduce BMR by up to 30%. These affect your daily energy needs.
Estimate resting calorie needs for weight management.
Integrate with our TDEE Calculator for daily calorie planning.
Track changes in BMR with regular weight or muscle updates.
BMR calculator is a tool which measures the basal metabolic rate or calories burned while your body is at rest. It calculates using age, weight, height, and gender so that it meets your BMR needs for planning weight loss or fitness goals.
To lose weight effectively, it is important to create a caloric deficit, consume lower calories than your BMR and activity levels. To achieve that step, input your details into our tool and the result shows your resting calorie burn.
Mifflin St Jeor is arguably the best-known Basal Metabolic Rate calculating equation. It uses weight, height, age, and even gender to provide the most accurate MBR estimate you can possibly get, enabling tailored fitness plans.
Just like our BMR Calculator , a resting metabolic rate calculator calculated all of the calories burned while on rest. You just have to input your details, and it utilizes the Mifflin St Jeor formula to estimate your daily caloric needs.
The BMR Calculator uses the Mifflin-St Jeor Equation to determine your Basal Metabolic Rate (BMR) considering age, weight, height, and gender. This formula is the most accurate for estimating these parameters and is specifically designed for metabolic research guaranteeing results when planning daily energy expenditure at rest. Its accuracy has been validated by the National Institutes of Health (NIH) through clinical research.
Weight loss usually decreases BMR (because there is less body mass), and muscle gain typically increases BMR (due to more body mass). When you sustain or experience a significant change in weight (such as every 10–15 lb), recalculate your BMR and adjust your caloric needs. You can get a full 24-hour caloric estimate by using our TDEE Calculator.
Yes, BMR represents the number of calories you use at rest. If you want to maintain your weight, add calories on top of your BMR for daily activities (as determined by our TDEE Calculator) and consume that caloric total. Depending on your lifestyle changes, you will need to adjust your caloric intake, while also monitoring your weight regularly to find the right balance.
