How to Calculate TDEE for Men: Formula and Examples

This article is for educational purposes only and is not medical advice. Talk with a qualified healthcare professional before making major nutrition, weight loss, or medication-related changes.

To calculate TDEE for men, find your BMR with the male Mifflin-St Jeor equation, (10 x weight in kg) + (6.25 x height in cm) - (5 x age) + 5, then multiply it by your activity factor (1.2 to 1.9). For most men this works out to between 2,200 and 3,000 calories per day, which is the number you burn and the amount you would eat to maintain your current weight.

Two details trip men up with generic calculators: the male version of the formula ends in +5 (the female version subtracts 161), and the activity multiplier you pick swings the result by 500 calories or more. Get those two things right and your TDEE goes from a random internet number to something you can actually build a cut or a bulk around.

Key Takeaways

Male TDEE = male BMR x activity factor - the men's Mifflin-St Jeor equation ends in +5, versus −161 for women
Most men land between 2,200 and 3,000 calories - sedentary men average 2,000-2,400, moderately active men 2,600-3,000
Male TDEE runs about 20% (roughly 580 calories) higher than female TDEE on average, mostly because men carry more lean muscle mass
Your real TDEE is probably lower than the calculator says - most men overestimate their activity level by at least one tier
Very muscular men should use Katch-McArdle instead - Mifflin-St Jeor can underestimate BMR by 100-200 calories if you carry well above average muscle

What Is TDEE for Men?

TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a full day, from keeping your heart beating to lifting, walking, and digesting food. For men, it typically falls between 2,200 and 3,000 calories, with the full range running from about 2,000 for smaller sedentary men to 3,200+ for tall or very active ones.

Your TDEE is built from three parts. Your basal metabolic rate (BMR) is the 60-75% you burn at complete rest. The thermic effect of food is the roughly 10% used to digest meals. Activity, from gym sessions to walking and fidgeting, makes up the remaining 15-30% and is the piece you control most.

TDEE matters because it is your maintenance line. Eat above it and you gain weight, eat below it and you lose. Every calorie target worth following, whether a fat-loss cut or a lean bulk, starts from this number.

How Do You Calculate TDEE for a Man Step by Step?

Calculating a man's TDEE is a two-step process: estimate BMR with the male formula, then multiply by an honest activity factor. Here is exactly how to do it:

Convert your weight and height to metric - Divide your weight in pounds by 2.205 to get kilograms, and multiply your height in inches by 2.54 to get centimeters. (A 190 lb, 5'10" man is 86 kg and 178 cm.)
Calculate BMR with the male Mifflin-St Jeor equation - BMR = (10 x weight in kg) + (6.25 x height in cm) - (5 x age) + 5. The +5 constant is what makes this the men's version; the women's formula subtracts 161 instead.
Pick your activity level honestly - This is where most estimates go wrong. Choose from the multiplier table below, and when you are between two levels, round down.
Multiply BMR by your activity factor - BMR x activity multiplier = your estimated TDEE.
Track for 2-3 weeks and adjust - The formula is a starting point. Log your food and weight, and if the scale isn't moving the way the math predicts, nudge your target by 100-200 calories.

Worked Example

Take a 35-year-old man who weighs 190 lbs (86 kg), is 5'10" (178 cm), and lifts 3 times a week:

Step 1 - BMR: (10 x 86) + (6.25 x 178) - (5 x 35) + 5 = 860 + 1,113 - 175 + 5 = ~1,800 calories

Step 2 - Activity factor: Lifts 3x/week plus a desk job = "Moderately Active" = 1.55

Step 3 - TDEE: 1,800 x 1.55 = ~2,790 calories per day

What Activity Multiplier Should a Man Use?

The activity multiplier is the biggest source of error in any TDEE estimate, and men are especially prone to picking one tier too high. Three hard gym sessions a week feels like a lot, but if you sit the other 95% of your waking hours, you are closer to lightly active than very active. One tier too high inflates your TDEE by 300-450 calories, enough to erase a planned deficit entirely:

Sedentary (1.2): Desk job, little walking, no structured exercise. This is most office workers, even ones who feel "kind of active."
Lightly Active (1.375): Light exercise 1-3 days a week, or a job with some walking. Roughly 4,000-7,000 steps a day.
Moderately Active (1.55): Intentional exercise 3-5 days a week plus 7,000-10,000 daily steps.
Very Active (1.725): Hard exercise 6-7 days a week or a physical job like construction, with 12,000+ steps daily.
Extremely Active (1.9): Twice-daily training or competitive athletics. Very few men truly belong here.

One more trap: the multiplier already includes your workouts. If you pick 1.55 because you train 4 days a week and then also add your watch's "500 calories burned" on top, you are counting the same exercise twice. Our guide on whether you should eat back exercise calories breaks down why that double counting stalls so many cuts.

What Is the Average TDEE for a Man?

The average adult man has a TDEE somewhere between 2,200 and 3,000 calories per day, roughly 20% (about 580 calories) higher than the average woman. To make that concrete, here is how the number shifts by activity level for a 40-year-old man who is 5'10" (178 cm) and 200 lbs (91 kg), with a BMR of about 1,830:

Sedentary (1.2): ~2,200 calories/day
Lightly Active (1.375): ~2,515 calories/day
Moderately Active (1.55): ~2,835 calories/day
Very Active (1.725): ~3,155 calories/day
Extremely Active (1.9): ~3,475 calories/day

Your own number moves with height, weight, and age, since BMR declines slowly over time, partly because men lose muscle mass each decade after 30 unless they train to keep it. But the pattern holds: a single jump in activity level is worth 300+ calories a day, which is why being honest about how much you actually move matters more than nailing the formula to the decimal.

Should Muscular Men Use a Different Formula?

Yes. If you carry well above average muscle for your weight, Mifflin-St Jeor can underestimate your BMR by 100-200 calories, and the Katch-McArdle formula is more accurate. Mifflin-St Jeor only sees your total weight, so it assumes an average body composition. Muscle burns more calories at rest than fat, which means a lean 190 lb lifter and a 190 lb sedentary man get the same Mifflin number despite genuinely different metabolisms.

Katch-McArdle works from lean mass instead: BMR = 370 + (21.6 x lean mass in kg). Our example 190 lb (86 kg) man at 15% body fat has about 73 kg of lean mass, giving a BMR near 1,950 instead of 1,800. The catch is that you need a reasonably accurate body fat percentage, so if you are guessing at that number, stick with Mifflin-St Jeor and adjust from real-world results instead.

How Do You Use Your TDEE to Cut or Bulk?

Once you have your TDEE, every goal is simple arithmetic against it. Eat below your TDEE to lose fat, at it to maintain, and slightly above it to build muscle.

Cut (lose about 1 lb per week): Eat at TDEE minus 500 calories. For a man with a 2,790 TDEE, that is roughly 2,290 a day. If you want the full breakdown by age and height, see our guide on how many calories a man should eat to lose weight.
Lean bulk (gain about 0.5 lb per week): Eat at TDEE plus 200-300 calories with adequate protein. Bigger surpluses mostly add fat, not extra muscle.
Maintain: Eat right at your TDEE, useful for diet breaks or holding a weight class.

One firm rule: do not set your target below your BMR. For most men that floor sits around 1,600-1,900 calories. Aggressive cuts under it tend to cost muscle, tank energy and testosterone, and end in rebound eating. If a 500-calorie deficit would push you under your BMR, use a smaller deficit and let the cut take a few extra weeks.

Frequently Asked Questions

What is the TDEE formula for males?

First calculate BMR: (10 x weight in kg) + (6.25 x height in cm) - (5 x age) + 5. Then multiply that BMR by an activity factor between 1.2 (sedentary) and 1.9 (extremely active) to get your TDEE. The +5 constant is what makes this the male version of the Mifflin-St Jeor equation.

What is a good TDEE for a man?

Most adult men have a TDEE between 2,200 and 3,000 calories per day. Sedentary men typically fall in the 2,000-2,400 range, while moderately to very active men land closer to 2,600-3,200. Your exact number depends on your age, height, weight, and activity level.

Is a TDEE of 2,500 calories normal for a man?

Yes. A TDEE of 2,500 sits right in the typical range for an average-sized man who is lightly to moderately active. It would mean eating about 2,000 calories a day to lose roughly 1 lb per week, or about 2,700-2,800 to lean bulk.

Why am I not losing weight eating below my calculated TDEE?

Usually one of two reasons: your activity multiplier was too generous, so your real TDEE is lower than the estimate, or you are eating more than you think, since studies show people underestimate intake by 30-50%. Tighten up your logging for 2-3 weeks before assuming the formula is broken.

How often should men recalculate TDEE?

Recalculate every time you lose or gain about 10-15 pounds, or every 8-12 weeks during a cut or bulk. TDEE drops roughly 75-100 calories for every 10 pounds lost, so updating it helps you avoid plateaus as you lean out.

How Kalo Helps You Hit Your TDEE Target

Calculating your TDEE takes two minutes. The hard part is eating against it accurately every day, because the cooking oil, the sauce, and the second helping rarely make it into a manual log, and those misses are why a "perfect" number on paper still doesn't produce results.

With Kalo's AI-powered photo tracking, you snap a picture of your plate and get an instant calorie and macro breakdown, no weighing or database searching required. Photograph a burrito bowl and Kalo identifies the rice, beans, protein, and toppings as separate items, so the total you log against your TDEE reflects what you actually ate, whether you are cutting to 2,300 or bulking at 3,000.
