| Goal | Caloric Intake | Notes |
|---|---|---|
| Weight Loss | 0 calories/day | 20% calorie deficit from TDEE |
| Mild Weight Loss | 0 calories/day | 10% calorie deficit from TDEE |
| Maintenance | 0 calories/day | Equal to your TDEE |
| Muscle Gain | 0 calories/day | 10% calorie surplus from TDEE |
These calculations provide estimates based on validated mathematical formulas. For the most accurate assessment, consult with a healthcare professional who can perform specialized tests like indirect calorimetry.
Remember that metabolism is influenced by many factors including genetics, hormonal levels, muscle mass, and age. Regular monitoring and adjustments are recommended when using these figures for nutrition planning.
Your metabolic resting rate (RMR) or basal metabolic rate (BMR) is the number of calories your body burns at rest to maintain essential functions like breathing, circulation, and cell production. Understanding your BMR helps you create an effective diet and exercise plan.
We have developed this metabolic resting rate calculator to help you easily calculate how many calories your body needs daily. Whether you want to lose weight, gain muscle, or maintain your current weight, this calculator gives you a clear idea of your body's energy requirements.
The metabolic resting rate (RMR) is similar to the basal metabolic rate (BMR) and represents the calories your body burns while at rest. This includes functions like:
Since RMR and BMR are closely related, they are often used interchangeably. Our metabolic rate calculator uses three scientifically approved formulas to calculate your BMR:
You can calculate your BMR using different formulas based on weight, height, age, and gender. Below are the equations:
Mifflin-St Jeor Equation (Most Accurate for General Population)
For Men:
BMR = (10 × Weight in kg) + (6.25 × Height in cm) − (5 × Age) + 5
For Women:
BMR = (10 × Weight in kg) + (6.25 × Height in cm) − (5 × Age) − 161
Harris-Benedict Equation (Older Model)
For Men:
BMR = 88.36 + (13.4 × Weight in kg) + (4.8 × Height in cm) − (5.68 × Age)
For Women:
BMR = 447.59 + (9.25 × Weight in kg) + (3.10 × Height in cm) − (4.33 × Age)
Katch-McArdle Equation (For People with Known Body Fat Percentage)
BMR = 370 + (21.6 × Lean Body Mass in kg)
Where Lean Body Mass (LBM) is calculated as:
LBM = Total Body Weight × (1 − Body Fat Percentage / 100)
Using our BMR calculator is simple. Follow these steps:
The table below shows the average BMR values for different age groups:
| Age | Male BMR (Calories/Day) | Female BMR (Calories/Day) |
|---|---|---|
| 18-25 | 1,800 - 2,100 | 1,500 - 1,800 |
| 26-35 | 1,700 - 2,000 | 1,400 - 1,700 |
| 36-45 | 1,600 - 1,900 | 1,300 - 1,600 |
| 46-55 | 1,500 - 1,800 | 1,200 - 1,500 |
| 56+ | 1,400 - 1,700 | 1,100 - 1,400 |
Your BMR or RMR is the foundation of your daily energy needs. If your goal is to lose weight, you should eat slightly less than your BMR while considering your daily activity level. If you want to gain muscle, you need to consume more calories than your BMR and focus on strength training.
Use our metabolic resting rate calculator to find your exact calorie needs and adjust your diet accordingly. This will help you achieve your health and fitness goals efficiently.
You can use the Mifflin-St Jeor equation based on your weight, height, and age. The formula is:
BMR = (10 × Weight in kg) + (6.25 × Height in cm) − (5 × Age) + 5 (for males) or −161 (for females)
A good RMR varies by age, gender, and body composition. On average, men have a BMR of 1,600 - 2,100 calories/day, while women have a BMR of 1,200 - 1,800 calories/day.
Yes, to lose weight, you should consume fewer calories than your total daily energy expenditure (TDEE). However, eating below your BMR for an extended period can slow down your metabolism and lead to muscle loss.
Yes, age, muscle mass, diet, and activity levels can affect your metabolism. Strength training and proper nutrition can help boost your metabolic rate.
The Mifflin-St Jeor equation is the most accurate for general use, while the Katch-McArdle formula is ideal for those who know their body fat percentage.
