How to Calculate TDEE for Women: 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 women, find your BMR with the female Mifflin-St Jeor equation, (10 x weight in kg) + (6.25 x height in cm) - (5 x age) - 161, then multiply it by your activity factor (1.2 to 1.9). For most women this works out to between 1,600 and 2,400 calories per day, which is the number you burn and the amount you would eat to maintain your current weight.

The reason a generic calculator often feels wrong for women comes down to two things most of them gloss over: the female version of the formula uses a different constant (that −161 at the end), and a woman's calorie needs shift across the menstrual cycle in a way men's simply don't. Get those two details right and your TDEE estimate becomes a number you can actually plan around.

Key Takeaways

Female TDEE = female BMR x activity factor - the women's Mifflin-St Jeor equation ends in −161, versus +5 for men
Most women land between 1,600 and 2,400 calories - sedentary women average 1,600-1,900, moderately active women 2,000-2,400
Female TDEE runs roughly 8-15% lower than male TDEE at the same weight, because women carry more essential fat and slightly less lean mass
Your TDEE rises about 100-300 calories per day in the luteal phase (the week or so before your period), so cravings then are partly real biology
Never set your target below your BMR - 1,200 calories is at or under BMR for the average woman

What Is TDEE for Women?

TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a full day, including everything from keeping your organs running to walking, exercising, and digesting food. For women, it typically falls between 1,600 and 2,400 calories, though it can be lower for petite, older, or sedentary women and higher 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 structured workouts to fidgeting and walking around, 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. It is the single number every calorie target, from a fat-loss deficit to a lean bulk, is built on top of.

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

Calculating a woman's TDEE is a two-step process: estimate BMR with the female 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 150 lb, 5'5" woman is 68 kg and 165 cm.)
Calculate BMR with the female Mifflin-St Jeor equation - BMR = (10 x weight in kg) + (6.25 x height in cm) - (5 x age) - 161. The −161 constant is what makes this the women's version; the men's formula adds 5 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 30-year-old woman who weighs 150 lbs (68 kg), is 5'5" (165 cm), and works out 3 times a week:

Step 1 - BMR: (10 x 68) + (6.25 x 165) - (5 x 30) - 161 = 680 + 1,031 - 150 - 161 = 1,400 calories

Step 2 - Activity factor: Works out 3x/week plus a desk job = "Lightly to Moderately Active" = 1.55

Step 3 - TDEE: 1,400 x 1.55 = ~2,170 calories per day

What Activity Multiplier Should a Woman Use?

The activity multiplier is the biggest source of error in any TDEE estimate. Research shows people overestimate their physical activity by roughly 50%, which can inflate your TDEE by 300-400 calories and quietly erase a deficit. Choose carefully:

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, with 12,000+ steps daily.
Extremely Active (1.9): Twice-daily training or competitive athletics. Very few women truly belong here.

What Is the Average TDEE for a Woman?

The average adult woman has a TDEE somewhere between 1,600 and 2,400 calories per day. To make that concrete, here is how the number shifts by activity level for an average 35-year-old woman who is 5'4" (163 cm) and 160 lbs (73 kg), with a BMR of about 1,410:

Sedentary (1.2): ~1,690 calories/day
Lightly Active (1.375): ~1,940 calories/day
Moderately Active (1.55): ~2,185 calories/day
Very Active (1.725): ~2,430 calories/day
Extremely Active (1.9): ~2,680 calories/day

Your own number will move up or down with your height, weight, and especially your age, since BMR slowly declines over time. But the pattern holds: a single jump in activity level is worth 200-300 calories a day, which is why being honest about how much you actually move matters more than nailing the formula to the decimal.

Why Is Female TDEE Lower Than Male TDEE?

At the same body weight, women have a TDEE roughly 8-15% lower than men. The main reason is body composition: women carry more essential fat and slightly less lean muscle, and muscle burns more calories at rest than fat does. That difference is exactly why the formula subtracts 161 for women instead of adding 5 for men.

The practical takeaway is that women generally cannot eat the same maintenance calories as a similarly sized man and expect the same result. It also means the safe floor for a deficit is lower in absolute terms, which is why aggressive targets backfire so often for women. If you are weighing a low number, our guide on how many calories a woman should eat to lose weight breaks down what is actually safe.

Does Your Menstrual Cycle Affect TDEE?

Yes. During the luteal phase, the roughly two weeks between ovulation and your period, BMR rises by about 100-300 calories per day, averaging close to +200. Rising progesterone nudges your metabolism up and tends to bring stronger appetite and cravings along with it. In other words, that pre-period hunger is partly real physiology, not a lapse in willpower.

Here is the nuance almost no generic TDEE page mentions: the worst response to luteal-phase cravings is to crack down harder. Your maintenance genuinely is higher that week, so eating a little more is often just matching your real expenditure. What matters for weight loss is your weekly average, not daily perfection. A slightly higher intake during the luteal phase, balanced against the follicular weeks when hunger settles, still nets out to a deficit.

This is also why your weight can jump 2-4 pounds in the days before your period purely from water retention. It is not fat, and it is not your TDEE calculation failing. If sudden scale spikes throw you off, it is worth understanding how TDEE and daily energy balance actually work so a single weigh-in doesn't derail your week.

How Do You Use Your TDEE to Lose Weight?

Once you have your TDEE, setting a goal is simple subtraction. Eat below your TDEE to lose, at it to maintain, and above it to gain. For sustainable fat loss:

Lose about 1 lb per week: Eat at TDEE minus 500 calories. For a woman with a 2,170 TDEE, that is roughly 1,670 a day.
Lose about 0.5 lb per week: Eat at TDEE minus 250 calories. Gentler and easier to stick with, especially if you are already fairly lean.
Maintain: Eat right at your TDEE, useful for diet breaks or holding a goal weight.

One firm rule for women: do not set your target below your BMR. For the average woman that floor sits around 1,300-1,400 calories, which is why a blanket 1,200-calorie target leaves so little room and so often stalls. If a 500-calorie deficit would push you under your BMR, use a smaller one instead.

Frequently Asked Questions

What is the TDEE formula for females?

First calculate BMR: (10 x weight in kg) + (6.25 x height in cm) - (5 x age) - 161. Then multiply that BMR by an activity factor between 1.2 (sedentary) and 1.9 (extremely active) to get your TDEE. The −161 constant is what makes this the female version of the Mifflin-St Jeor equation.

What is a normal TDEE for a woman?

Most adult women have a TDEE between 1,600 and 2,400 calories per day. Sedentary women typically fall in the 1,600-1,900 range, while moderately to very active women land closer to 2,000-2,400. Your exact number depends on your age, height, weight, and activity level.

Should women eat more during their period?

Your metabolism is actually highest in the week before your period (the luteal phase), when BMR rises about 100-300 calories per day, not during bleeding itself. Eating slightly more during that window often just matches your real expenditure. Aim for a weekly calorie average rather than forcing the same number every single day.

Is 1,200 calories below a woman's TDEE?

Yes, well below it. The average woman's TDEE is 1,600-2,400 calories, and 1,200 is at or under her BMR, the bare minimum needed for basic functions. It can create too large a deficit, which is why many women stall or rebound on a 1,200-calorie diet.

How often should I recalculate my TDEE?

Recalculate every time you lose or gain about 10-15 pounds, or every 8-12 weeks during active dieting. A smaller body burns fewer calories, so your TDEE drops roughly 75-100 calories for every 10 pounds lost. Updating it helps you avoid stalls as you progress.

How Kalo Helps You Hit Your TDEE Target

Calculating your TDEE is the easy part. The hard part is eating against it accurately, because studies consistently show people underestimate their intake by 30-50%, which is the real reason a "perfect" number on paper still doesn't produce results.
