The basal metabolic rate (BMR) and calorie calculator is an excellent tool for estimating how many calories your body needs on a daily basis depending on the amount and intensity of your exercise regime.

BMR + Daily Calorie Calculator

Measurement Units:
Bodyweight:
Lbs
Kgs
Height:
Ft
In
Cm
Age:
Gender:
Activity Level:

This BMR calculator tool works on a proven formula and is very accurate. The calculator uses two formulas to calculate your body's daily calorie requirements.

  1. Basal Metabolic Rate (BMR) Formula
    The basal metabolic rate formula takes several variables like height, weight, age and gender to calculate your calorie needs as if you did not do any exercise.
  2. Harris Benedict Formula
    The Harris Benedict Formula takes the number produced by the BMR formula and multiplies it depending on your activity level.

The only factor it omits is lean body mass and thus the ratio of muscle-to-fat a body has. Remember, leaner bodies need more calories than less leaner ones. Therefore, this equation will be very accurate in all but the very muscular (will underestimate calorie needs) and the very overweight (will over-estimate calorie needs).

I’ve recently started lifting weights and I’ve noticed that I have gained a little fat in the midsection. I haven’t increased my calories drastically, but, I’m trying to build muscle. I am very lean after losing 120lbs. Is this normal?

Hi, Dane. First, congrats on that weight loss! Yes, it is normal for someone in your position to notice fat gain. Slightly cut back on the number of calories you're taking in, or add more cardiovascular training to your program. This will help keep the focus on building muscle.

Hello! I am 25 years old and about 83kg and 191cm. I usually do bodyweight strength exercises for 60-90 minutes 3 times a week and 10-30km of jogging at 11-15km/h 3 times a week. Should I then select very active or moderately active?

Thank you,

Hey there! I am a 63 y.o. white old man. I've been working out most of my adult live and have struggled losing even 1 pound.... I'm 6'1" 217lbs and want to really lean out before I got into "the home" where I will eat apple sauce, drink Ensure, and get my diaper changed daily. I currently work out 4 to 5 times a week/ cardio about 4 times a week. The BMR calculator shows mean consuming 2971 cals- WHAT? So.... is that for real and if so, what would my calorie deficit go to? Please advise and thank you for you time.

I lift 4 days a week for roughly 45-50 mins and then do 12 mins of walking at an incline as a warm up and cool down. Outside of that I’m not all to activate in my day to day so would I put that down as lightly active.

Hey Jonathan - you can go with lightly active and follow those calories for 4ish weeks and if you're not making the progress you want, you can up your calories.

Hey there!
First things first, this is one of the best articles I've ever read on fitness & lifestyle sphere. I want few suggestions from you to make my journey to building muscle a lot more fun & efficient.
I'm 20 years old,6''1', and my body weight is 163 pounds. The calculator says to take 2910 calories per day to maintain body weight. I want to do a 12 weeks muscle building training by training 5days/week. I have researched your website and have come to know about the right workout routine, diet options, and supplements for me.
The challenging part for me is I don't know how to fix the exact amount of a certain nutrient in my diet and which nutrient source to select for the right nourishment. I could really use some help in integrating a muscle build diet according to my profile, if you provide any help in such cases. Looking forward to hearing back from you.
Your avid reader,
Kumar

It did this for me too, its because i was filling out height as 5'4, not by inches or CM as it says. once i put in 64 for inches it showed my results.

Hey Stephanie - is the 1728 lower than what you're currently eating? When you start the 21 day shredding workout, you'll want to change your 'activity level' in the BMR calculator to fit the activity level of that workout.

Anthony

So I put in your measurements and it came out as 2,112 calories per day.

Lawrence
Posted on: Sat, 07/31/2021 - 10:52

Hi Noah,
Your height should be input in Feet and inches. You are 5 foot 2 inches being 62 inches tall. I also put your age as 16 since 14 wasn’t available. 2,273 calories was the calculated amount you need to maintain your current weight. You are an appropriate weight for your height according to the Body Mass Index. As a young person you should focus on eating nutritious food and not be concerned about calories as you are not overweight. You must increase your calories should you wish to gain weight but focus on whole foods to support your body as your body is still growing.
Eat quality meats, vegetables and fruit. Avoid fast food and sweets having them as the occasional treat.
Hope this helps
Lawrence

Hey Tracy - 1400 calories is low, even for weight loss. I also think you may have entered an incorrect piece of information into the calculator. When I plug my numbers (130 lbs, 62 inches, 23 years, female, moderately active), I get 2100 calories.

Hello!

I am 5'1 (61 inches) and around 135lbs. My daily calorie requirements are 1934 calories per day. My goal is to lose weight. So I would subtract 500 from that number for a total of 1434 calories per day. I still feel like that's too many calories. I'm planning on doing the Fast&Furious workout plan because I'm going on a trip that I would like to tone up for. Would you recommend I stay at 1434 calories per day?
