What Is My Maintenance Calories? (How to Find Your Exact Number)
Your maintenance calories are the number of calories you can eat each day without gaining or losing weight. Eat less than maintenance and you lose fat. Eat more and you gain. Everything in dieting starts from this one number.
So what is your number? The fastest estimate comes from our TDEE Calculator — your maintenance calories and your TDEE are the same thing. This guide explains what maintenance really means, the average ranges, and how to find your real number with a simple 2-week test.
Most adults maintain their weight on roughly 1,600–3,000 calories per day, depending on body size and activity. Your personal maintenance is your TDEE: your BMR multiplied by your activity level. The only way to know it exactly is to eat at a target for 2–3 weeks and watch your weight trend.
What does maintenance calories mean?
Maintenance calories are the energy balance point of your body. Through the day you burn energy on resting functions (your BMR), digesting food, daily movement, and exercise. When the calories you eat match the calories you burn, your weight stays stable — that match point is your maintenance.
It is not a fixed number forever. Maintenance changes when your weight, muscle mass, activity, or even your job changes. That is why long-term dieters sometimes find their old maintenance no longer works.
Maintenance calories vs TDEE vs BMR
BMR
What you burn at complete rest just to stay alive. Usually 60–70% of your total burn. Calculate it with our BMR Calculator.
TDEE = Maintenance
Your Total Daily Energy Expenditure — BMR plus all movement and digestion. By definition, eating at your TDEE means eating at maintenance.
Deficit
Eating below maintenance, usually 300–500 calories less, for steady fat loss that protects muscle.
Surplus
Eating above maintenance, usually 250–500 calories more, to support muscle gain with minimal fat gain.
Average maintenance calories
These ranges are rough starting points for adults. Your real number can sit outside them, especially if you are very tall, very muscular, or have a physical job.
| Person | Sedentary | Lightly active | Moderately active | Very active |
|---|---|---|---|---|
| Smaller woman | 1,600–1,800 | 1,800–2,000 | 2,000–2,300 | 2,300–2,600 |
| Average woman | 1,800–2,000 | 2,000–2,200 | 2,200–2,500 | 2,500–2,900 |
| Smaller man | 1,900–2,100 | 2,100–2,400 | 2,400–2,700 | 2,700–3,100 |
| Average man | 2,100–2,400 | 2,400–2,700 | 2,700–3,100 | 3,100–3,600 |
How to calculate your maintenance calories
The standard method: calculate BMR with the Mifflin-St Jeor formula, then multiply by your activity level.
Men: BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age + 5
Women: BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age − 161
| Activity level | Multiplier | What it usually means |
|---|---|---|
| Sedentary | 1.2 | Desk job, little or no exercise |
| Lightly active | 1.375 | Light exercise 1–3 days/week or regular walking |
| Moderately active | 1.55 | Exercise 3–5 days/week, fairly active lifestyle |
| Very active | 1.725 | Hard exercise 6–7 days/week or physical job |
| Extra active | 1.9 | Athlete training or very physical job plus workouts |
This gives you an estimate. The test below turns the estimate into your real number.
How to find your REAL maintenance calories (the 2-week test)
Calculators estimate. Your body tells the truth. Here is the simple test coaches use:
- Step 1: Take the calculator estimate as your starting target.
- Step 2: Eat as close to that target as you honestly can for 14 days. Weigh your food with a kitchen food scale — eyeballing portions is the #1 reason this test fails.
- Step 3: Weigh yourself every morning after the bathroom, before eating, and record it. A smart scale that syncs to an app makes the trend automatic.
- Step 4: Compare your average weight of week 1 vs week 2. Stable (within about 0.5 lb / 0.25 kg)? You found maintenance. Drifting up or down? Adjust by 100–200 calories and repeat.
Digital Kitchen Food Scale
The maintenance test only works if your intake data is honest. A gram-accurate digital scale removes guessing from oils, rice, snacks, and everything in between.

- Your 7-day average weight stays within a small range week to week
- Your gym performance and energy feel steady
- You are not constantly hungry or constantly full
- Your waist measurement stays the same
What to do with your maintenance number
Once you know your maintenance, every goal becomes simple arithmetic:
- Lose fat: eat 300–500 below maintenance. Split the target into protein, carbs, and fat with our Macro Calculator — and protect muscle by hitting protein daily, with food or a protein shake on busy days.
- Gain muscle: eat 250–500 above maintenance and train with progressive overload.
- Take a diet break: after 8+ weeks of dieting, 1–2 weeks at maintenance restores energy and hormones before you continue.
- Stay organised: meal prep containers make hitting any of these targets far easier during a busy week.
Whey Protein Powder
Whether you are cutting, maintaining, or bulking, protein is the macro that matters most. A whey shake is the simplest way to stay consistent when whole-food protein falls short.

If the scale creeps up at your supposed maintenance, one of three things is usually true: your intake is higher than logged (oils, bites, and liquid calories are the classic leaks), your activity dropped without you noticing, or water weight is faking a trend — judge by 3–4 week averages, not single days. Our guide on why you are not losing weight on a calorie deficit walks through each cause and fix. And if you want the full picture of daily burn, read how many calories you burn a day.
Frequently asked questions
What are maintenance calories?
Maintenance calories are the number of calories you need to eat each day to keep your current weight stable — neither gaining nor losing. They equal your TDEE, the total energy you burn in a day.
How do I find my maintenance calories?
Start with a TDEE calculator estimate, then eat at that target for 2 to 3 weeks while tracking your morning weight. If your average weight stays stable, that is your maintenance. If it drifts, adjust by 100 to 200 calories and test again.
Are maintenance calories the same as TDEE?
Yes. TDEE is the total number of calories you burn per day, so eating exactly your TDEE keeps your weight stable — which is the definition of maintenance calories.
How many calories should a woman eat to maintain weight?
Most women maintain on roughly 1,800 to 2,500 calories per day depending on size and activity. Sedentary smaller women may maintain near 1,600, while very active women can maintain above 2,900.
How many calories should a man eat to maintain weight?
Most men maintain on roughly 2,100 to 3,100 calories per day depending on size and activity. Very active men or men with physical jobs can maintain well above 3,500.
Do maintenance calories change over time?
Yes. Losing or gaining weight, building muscle, changing jobs, moving more or less, and aging all shift your maintenance. Recheck with the 2-week test whenever your weight trend changes unexpectedly.
Your maintenance calories are your TDEE — the point where food in equals energy out. Estimate it in seconds with the TDEE Calculator, then confirm it with the 2-week test. Once you own that number, fat loss, muscle gain, and diet breaks all become simple math.
