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

Couldn't get it to work
It didn’t work for me. All fields were filled in and I even changed out 5’7” to total inches. I put 125 lbs and then took out lbs and it still stated “please fill in all fields”. Suggestions?
You need to put your height in inches only, so for you it would be (5 x 12) + 7 = 67 inches. Also only put numbers in the fields, not letter like "lbs"
Worked perfectly fine for me.
I put in everything and my height I did in cm
It worked for me. The only thing I changed was instead of putting down 5’7 as my height , I only wrote down 57 . I’m not sure if that works for everyone but it’s near to my TDEE using a different calculation
Hope this helps
you have to put your height in inches. for you thats 67
This is bogus you’re right it don’t work
Only enter the number for age, height, and weight
I filled in every section and received absolutely nothing to tell me about my calorie intake or my metabolic rate. Please get this right as I see that I am not the only one who was disappointed.
Must do better.
Only use numbers for weight, height, and age.

Same as Clarke (below). Been getting this message for several weeks. Just figured it doesn't work.
Actually the calculation is fairly spot on. My calorie consumption reads just under 3200. When I have previously set a daily target of 2800 , I managed to loose about half a pound a week. Does not sound much, but starting in February I found that I had shed about 10 pounds come mid June. Not a huge amount but I was only 14 stone to start with and I found that I had cut down to a healthy look. Didn’t feel hungry and it disciplined me to eat properly so I didn’t use up my allowance on ‘empty ‘ calories. Ultimately this works as long as you are honest with how you rate your activity.
can you please tell me what your meal looks like on an average day? thanks
I keep getting a message saying I need to fill in all fields. I have field in all fields. I am not sure what I am doing wrong.
I just tried it in Lb's and it worked fine
Works fine for me too. Compared to the Naval Biometrics Test I just had done, it's a little under 100kcal difference. That's totally acceptable x
It usually mean I filled something in wrong. Ex: when I accidentally fill out my height as 6’3, instead of 75
Change your keyboard language to English. The numbers must be Like this "123". This problem occurs when I write the numbers in Arabic like this ١٢٣.
Enter your height in inches if using US in example if you are 6 feet 2 inches tall enter 74 for the number that should be your problem
انا عمري 28سنة ووزني 52 kg و طولي 163cm
انا عمري 21 سنة ووزني 45 مع العلم طولي 1.69 انا اريد الزيادة في وزني لاني اعاني من النحافة
You have to take your number and add about 500 calories to it.
Hit the gym and increase your protein intake such as meats eggs fish and chicken
5’6”, 220lb male. BMR given is 2801. Picked the lowest amount of exercise listed. Jogging 3-4 days a week, Muay Thai 1 or 2, lifting 1-2. Most workouts are about 45 minutes each across the board. A different app gave me a goal of 1850 cal/day to lose weight, hasn’t been working. Am I having issues dropping weight because I’m eating too little?
Weight loss is not always a straight downward path. Sometimes, it halts, other times you gain a little, and loose back next week.
In my case I have managed to shave off a lot of extra weight by doing intermittent fasting and eating mostly healthy meals, no fast food, no juices, no deep fried foods and less processed sugar & meats. I do allow myself 1 day / week to cheat-eat a little unhealthy and higher calorie mean (but I don’t go overboard). In my opinion Cheat days are important because you don’t stress your body with low calories everyday and your metabolism will stay “sharp”.
Try counting your calories, but I would say 2800 kal / day is a lot. Try to figure out how many calories you burn daily without workouts and substract 500 (to loose weight). In my experience, loosing weight is food, not exercising. Exercise helps you, but really 90% is the food we eat.
You mean kilocalories, right? With 4 kcal a day, I'd die of hunger.

After doing the calculator obviously it already has the activity level calculation in it so you dont need to multiply anything more...correct
YOUR DAILY CALORIE REQUIREMENTS ARE:3084 CALORIES PER DAY. I never can reach this mount of calories per day, the max that I_ had is under 2000 ca. Is that a problem?
I noticed it said walking for Cardio. Can I jog/run on treadmill, do elliptical, or even concept 2 rower. I am currently 169lbs and trying to get to 155lbs in around 8 weeks.
Hi. I'm 35, female, 155 pounds, 5 feet 3 inches. The calculator is telling me my BMR is 2002 calories. I have used a BMR calculator in the past and it said my BMR was closer to 1475, so I'm not sure what to think. I lift weights 4 days/week for about 75-90 minutes, followed by 30 minutes of cardio. I have been limiting my calories to about 1300/day. I really need more information on how much protein, calories, etc I need to be consuming in order to gain lean muscle and lose body fat. Everything I read tells me something different. I have lost about 10 pounds and I've been following this routine for almost 2 months. Any help is appreciated. Thanks!
I think this calculates TDEE and not BMR since it asks for your activity level, and BMR (if I'm not mistaken) does not take into account your daily activities/workouts. I'd say just based off of what your stats are, you're probably eating too little if you're consistently as active as you say. I'm 5'4" 120lbs and my bmr/rmr is 1350 and eating 1600 calories while working out 6 days a week is still a pretty significant deficit for me. Try comparing your results on other TDEE sites and maybe average it out?
Agreed. And extra points for the name used.
1300 cal day is WAY too little. You need to be eating muchmore, esp proteins and good fats, veggies. If you're in gym 2 hrs 4x a week you are not fueling for building muscle by eating so little. Up that to 1800, of which is proteins and good fats.
For maximum protein intake, I follow the words of Arnold Schwarzenegger, 1gram of protein per body weigh (LB), should be your daily protein intake. At 155lbs you could be consuming a maximum of 155grams of protein daily. I too have been working on building lean muscle while burning fat. I have learned, through my experience and research, that hitting your macros and working out consistently are vital to my progress. I am struggling now to find exact macros target which will maximize my growth. Hope this helps
What does the resulting answer mean?
My calories are 3150
And I want to increase my weight ten kilo how?
Hi Maddi,
The result provides your maintenance calories. To increase your weight, you'll want to add calories to that number. My recommended added calorie amount would be ~250-500 calories on top of your results.
Thanks alot joshengland
Add 500 onto your nb to add 1lb a week same for losing but minus 500 off the number
This is a tdee calculator (bmr + activity) so just add or minus 500 of the number if wanting to gain or lose ,recalculate every 2 weeks
Another factor here is the job calories isn't inc only bmr and activity, if your a grafter like a scaffolder compared to office job these calories vary I would add 1000 cals if labour work and 200 if casual onto the total
I am 26 years old and 1.80 years tall and weigh 63 kg and very thin
I'm 24 years old , female , 44 kg ,156 cm, my body is like a ruler . l want make shape for my glutes to become bigger . l'm soo.. sad because the shape of my body . please help me.
I have watched ‘florina fitness’ on YouTube that has helpful tips on developing curves!!! I just found her a few days ago.
this calcualtor is buggy. depending if you use inches or cm gives you an amount that is wildy different.
I disagree. I put in my accurate information for both because I saw your post and there was a 4 calorie difference. I would suggest checking the math on your conversions to make sure they are accurate. There is nothing wrong with this calculator.
The calculations are different but not wildly different..... Make sure you changed weight to lbs as well
Yes,with cm 3150cal men with insh2000cal
For the Sam person
