Macro Calculator
This free, easy-to-use macro calculator gives you your optimal macronutrients and calories. It serves as a weight loss or muscle gain calculator for both women and men.
Combine with macro counting, flexible dieting, or IIFYM to reach your goals faster.
How to calculate your macros for fat loss
The foods we eat are made up of three macros (macronutrients). These are carbohydrates (carbs), protein, and fat.
Chicken is high in protein but has no carbs; rice is high in carbs but has very little fat or protein.
The three macronutrients provide the body with energy and raw materials for growth and repair.
By calculating the appropriate daily calorie amount for you, we can then break this down into the best macronutrient ratios to achieve weight loss.
The calculator is based on sound science, combined with data from years of coaching hundreds of successful clients.
What is a good macro ratio for fat loss or muscle gain?
Your macros should be based on your Total Daily Energy Expenditure (TDEE) and your goals.
The calculator defaults at the best macro ratio proven to work for most people.
This ratio is:
- 30% fat
- Protein is 0.65 grams per pound of body weight,
- The remainder is carbs.
Depending on your goal, this will be either a calorie deficit or a surplus.
You can go further and make more adjustments: Perhaps you’re an extreme endomorph and do better with fewer carbs. Or perhaps you have one kidney and need to eat less protein.
You can fine-tune your results for you with a bit of math. See how to change your macros here.

- Individually tailored to your body composition.
What is a good protein ratio?
Rather than a percentage, proteins are based on your body weight.
Our calculator has three settings:
- Moderate adjusts the ratio to 0.65 grams per pound of body weight.
This is appropriate for sedentary individuals or people with higher body fat percentages. - High is for active people with moderate strength training and an average body fat percentage.
- Maximum will set the ratio to 1 gram per pound.
This amount is good for bodybuilding and gaining muscle mass. You must be doing intense training.

Fat macro ratio
Set fat at 30% of daily energy expenditure.
Most people do very well with this amount of fat. See more about choosing the best macro fats. Because of high-fat diets like keto, many people are now eating more fat than they need to.
Carbohydrate macro ratio
Once you’ve calculated protein and fat, the remainder of your daily calories should be from carbohydrates.
Carbs fuel your body and workouts and are the body’s preferred energy source.
If you are coming from a low-carb background, this may seem high. However, according to respected nutritional research, this is a moderate amount of carbs.
If you are eating according to your TDEE, the notion that carbs cause weight gain or stop fat loss is incorrect.
Using as a Calorie Deficit Calculator
As a weight loss calculator, this tool establishes a safe calorie deficit only.
The Lose option puts you in a 20% calorie deficit, promoting safe, steady weight loss.
The best macro ratio for body recomposition
If you want to recompose your body (lose fat and gain muscle simultaneously), then use the body recomposition calculator.
Macro ratio for maintenance
The Maintain button shows you the macro levels to maintain your current weight.
This is great if you have lost weight and don’t want to gain it back.
Macro ratio for muscle gain
The Gain button puts you in a 20% calorie surplus.
The macro breakdown is designed to build muscle fast in conjunction and must be combined with a comprehensive weight training program.
It can also be used by people who are underweight.
TIP: Try starting with the maintenance goal and then gradually increase calories from there if you want lean muscle gains.
Calculating macros using your body fat percentage
The calculator uses your body weight to determine calories and macros.
However, you can obtain superior results by using your body fat percentage. The calculator allows you to choose which method; Normal for body weight, Lean Mass for fat percentage.
When to choose the Lean Mass Formula
If you are lean (have a low body fat percentage), choose the Lean Mass formula, and enter your body fat %.
If you are classified as obese and have a lot of weight to lose, the lean mass formula is superior. You can read more about macro counting and obesity.

Why the difference? Muscle cells burn more calories than fat cells, so the more accurately we measure this, the better your results will be.
How to calculate macros per meal
Once you’ve calculated your daily macros in the calculator, you can break this down into meals.
Choose from 2 to 6 meals per day to see the macro ratio you can track for each meal. For some people, this is easier, but for others, this is too much detail.
Do what works for you.
Meal Plans
See a 5-day macro-based meal plan. It includes three meals and two snacks per day.
Macro calculator activity level settings
A higher activity level means a higher daily calorie goal.
For example – if you maintain your weight at 2,000 calories per day, adding vigorous daily exercise means you need more calories to maintain your weight.
If you are sedentary and trying to lose weight, adding exercise will increase your daily calorie goal.
The idea seems counter-intuitive, but more energy is required to fuel your workouts. More workouts lead to increasing metabolism; therefore, more fat is burned!
Undereating is one of the leading causes of the weight loss plateau.
So many of our clients previously “hit the wall” with dieting. They would continually reduce calories, stop losing fat and gain weight when they eat a little more.
Macro counting defeats this by prescribing the right food and calorie levels.
Which activity level do I choose?
- Sedentary: Just regular everyday activity like a bit of walking, a couple of flights of stairs, eating, etc.
- Light: Any activity that burns an additional 200-400 calories (females) or 250-500 calories (males) over your sedentary amount.
- Moderate: Any activity that burns an additional 400-650 calories (females) or 500-800 calories (males) more than your sedentary amount.
- Extreme: Any activity that burns more than 650 calories (females) or more than 800 calories (males) in addition to your sedentary amount.
Other options for determining your calorie burn
- Use our calories burned calculator – it accurately assesses over 380 activities.
- Use a fitness tracker – like a Fitbit or Apple Watch (note that they can overestimate calorie burn).
- Use a suitable app – like MapMyFitness
Why should I eat more when I exercise more?
High physical activity not fueled with enough calories will lead to muscle catabolism (breakdown of muscle fiber).
This lack of nutrition could stall your weight loss, so eat up if you love to exercise!
I’ve got my macros – now what?
Once you’ve identified your target daily macros, you must determine the macros in all the foods you eat.
By tracking them daily, you can reach your recommended macro targets that encourage fat loss, muscle gain, or whatever your goal may be.
You can learn more about the macro counting system and the flexible dieting philosophy. Many people use an app like Myfitnesspal to track macros.
For more specifics on what to eat – see a sample macro meal plan or a list of macros for familiar foods.

So is the goal to stay under your macros or hit that exact amount? I.e is the macros listed the maximum amount you should be getting or are they the daily aim
Hi DJ, You goal is to hit your targets as closely as possible. We encourage people to try to be within 5 grams of your macro targets.
Hi Ted,
So as per your suggestion I was looking to readjust my macros in MFP after losing 10lbs. However, i soon realized that since i don’t have the premium version it doesn’t let me adjust my macros at 1% increment and therefore i need to round it of to the nearest 5% increment. By doing so my macros are still the same (40C,30P,30F) as before when I was 10lbs heavier. Is there a better way to adjust or represent it? If not, how do i ensure i continue losing weight?
Hi Nania, with 10 pounds lost you won’t see that much difference in your macros. About 2-3 grams lower in carbs and protein and 1 gram lower in fat. Therefore, don’t stress over it and continue as is. Great job on the 10 pounds, that’s awesome!
Thank you! 😊👏😊
What if my activity varies day to day? 3 days I run 10km-20km (road and trail) 3 days I do strength work, and 1 or 2 days, I rest. so is it moderate? light?
For people who have varying degrees of activity, often it’s a good strategy to use your sedentary TDEE as your base and then add in the calories burned by various exercises. This way you are eating better in tune with what your body needs on a given day. We show you how to set this up in MyFitnessPal here.
So what should my initial goal be if I am skinny fat (skinny arms and large layer of fat surrounding abdomen). I want to gain some lean muscle( increase size of arms, chest, etc) but also reduce fat around my abdomen. Should I look to lose 10%, cut or gain/bulk first for a skinny fat person aiming for a lean & shredded look
Hi Shanny, If you have less than 10 pounds to lose, you should go with “lose 10” and high protein in conjunction with a comprehensive weight lifting program.
Hi James,
I am unsure about the carbs. I want to cut a bit from 86 kg to about 80 kg in the next 2-3 weeks. The carbs seems a bit high at 249 grams? Then again, I don’t want to lose any muscle mass while cutting either so just want to confirm if I should stick to 249 g carbs and if so – what foods do you suggest?
Hi Duan, If you’re extremely active that level of carbs is what you want. Carbs do not make you can weight or keep you from losing weight when you are in a calorie deficit. You want most of your carbs to come from whole food sources like vegetables, fruit, and whole grains.
Hi my name is TJ. I’m 62 years old 5’2”105 pounds and I’m looking to gain weight. I burn about 1100 cal a day. When I put all my information in the calculator and I chose “gain” it only said I needed to eat 793 cal. Currently I eat approximately 1000 cal a day and it’s still difficult for me to maintain or gain weight. So can you tell me why the calculator is only giving me 793 cal a day when I’m eating to gain weight not lose it?
TJ I input your stats, and with an activity level of Extreme, it shows 2394 calories/day.
Hello! My name is Adi , and I was wondering how can I get more carbs , what I need to eat?
Thanks!
Adi, please see our list of best carbs here: https://healthyeater.com/carb-protein-fat-rich-foods
Hi Adrian, Here’s a good article on carb food sources.
Does the fat contain saturated fat?
Hi Song, The fat macro includes all types of fats. It’s your “total fat” for the day.
Hi Ted,
I just wanted to shout out and thank you for all your advise in this macro journey. I’ve been seeing some great results with this diet and I finally seem to figure it out. I started my journey with 143lbs and have come down to 136lbs. I do see some muscle gains as well 💪 I can see results from everywhere except for my belly. Is there anything additional I can do to get rid of some belly fat? My goal isn’t to have a six packs abs but I just want to reduce some fat from my belly. My current macros are P123, C165, F55. I’m 5’3” and weighed 143lbs (when I’d started)
Thanks you!!
Hi Naina, Great job and thanks for taking the time to let us know. I’m so glad I was able to help. With belly fat, keep doing what you’re doing. Around the abdomen is usually the first place fat is stored and usually the last to go. You’ll want to readjust your macros when you get down to 133 lbs.
Aha! I’ll hang in there. Thank you again 🙂
Should the carb grams I consume be net or total?
We normally advise counting total carbs (as it’s easier). This will also give you a small buffer on your carb count for the day (typically the easiest macro to overeat). For example, if you are aiming for 100g carbs a day – the actual amounts that you eat might be 90g digestible (net) carbs and 10g indigestible fiber. This means you have a small buffer of 10g if you overeat carbs (hope that makes sense).
Just wanted to shout out and say thank you! Three years ago I figured out the macro math on my own and tracked a routine in which I was training at the gym 6 days a week. I’ve always had a very lean body build, but wanted to pack on muscle for strength that made me feel accomished at the gym. I kept up with extreme training, six days a week up to two hours a day for three months. I gained 15 pounds of muscle allowing my power ratio to go from 1 to 1.75. I have struggled to figure out the math since then and loss weight due to work stress and poor eating. Now I have been craving a wicked training routine again. So thx for having this calculator it makes things a lot easier and will give me more motivation to gain that muscle back and maybe go beyond! Macros work, I wish more of my gym buddies could find this website : )
Happy to help. Please come back and let us know how you get on… we’re always trying to improve the calculator.
New to this.
Every factor I plug in never gives 100% nutritional value for each category.
Even if trying to gain weight.
Only hits at most 50% of recommendation for daily value.
?
Could you elaborate? I’m not sure I understand. What do you mean by category?
