Maintenance Calorie Calculator | Find Your Daily Calorie Level
Use this free maintenance calorie calculator to find the exact number of calories you need each day to hold your body weight steady. Built on the Mifflin-St Jeor formula with a 14-day verification protocol to confirm your real maintenance level.

What Are Maintenance Calories?
Your maintenance calories are the number of calories you need to eat each day to keep your body weight stable. They are the same as your Total Daily Energy Expenditure. Eating at maintenance is the foundation of long-term body composition management, a sane relationship with food, and sustainable performance in and out of the gym.
Most adults land between 1,800 and 3,200 calories at maintenance depending on size, age, sex, and how much they move each day. The number the calculator gives you is a starting estimate. Your real maintenance is confirmed by tracking your weight average over 14 days at that calorie level. Use the BMR Calculator to see the resting metabolic component of your maintenance number before the activity multiplier is applied.
Most adult women maintain body weight between 1,800 and 2,400 calories per day, depending on height, age, muscle mass, and daily activity level.
Most adult men maintain body weight between 2,200 and 3,200 calories per day, with the higher end reflecting greater lean mass and higher activity.
Eating at maintenance for 1 to 2 weeks after a cut resets hunger hormones, restores NEAT, and rebuilds training quality before the next fat loss phase.
Maintenance is a sustainable long-term eating pattern for people who have reached their goal weight and want to hold it without tracking a strict deficit or surplus.
How Does the Maintenance Calorie Calculator Work?
The calculator uses your body stats and activity level to estimate TDEE, then returns that number as your maintenance target with a built-in verification method.

What Factors Shape Your Maintenance Calories?
Maintenance is not a fixed number. These are the variables that move it up or down through different phases of life and training.
Body Weight and Lean Mass
Larger bodies contain more cells to fuel, so maintenance calories scale directly with body weight. Lean muscle mass raises the resting metabolic rate above what total weight alone predicts, which is why two people at the same weight can have maintenance levels that differ by 300 to 500 calories per day.
Daily Steps and NEAT
Non-Exercise Activity Thermogenesis covers all movement outside structured workouts: walking, standing, fidgeting, and household activity. NEAT can vary by 1,500 to 2,000 calories per day between sedentary and active people of the same size, making it the most powerful variable for raising or lowering your maintenance level.
Training Volume and Frequency
Structured exercise adds 5 to 15 percent to TDEE depending on weekly volume and intensity. Adding training raises maintenance. Reducing or stopping training drops it within 2 to 4 weeks. People who track maintenance during an injury or off-season often find it falls faster than expected without their regular sessions.
Protein Intake and Thermic Effect
Protein costs roughly 25 percent of its own calories to digest and process, compared to 5 to 10 percent for carbohydrates and 2 to 3 percent for fat. Eating more protein slightly raises your maintenance level through this thermic effect and also preserves the lean mass that keeps your metabolic rate from dropping over time.
Diet History and Metabolic Adaptation
Extended periods of aggressive dieting can lower TDEE by 10 to 20 percent through adaptive thermogenesis, where the body reduces resting metabolism to conserve energy. People with a long history of crash dieting often find their real maintenance is well below the formula prediction until they spend time eating at higher calories to restore it.
Sleep Quality and Stress
Poor sleep reduces NEAT the following day and suppresses thyroid function, both of which lower maintenance calorie needs without any change in body weight or muscle mass. Chronic psychological stress elevates cortisol, which promotes fat storage and reduces the metabolic rate at which your body processes food.
How Do You Use Your Maintenance Calories?
Maintenance is a flexible tool. It functions as a steady state, a recovery phase, or a bridge between more aggressive diet blocks.
Hold Your Weight Steady
Eating at your maintenance calorie level keeps body weight stable over weeks and months. This is the foundation of long-term body composition management. Verify your real number with a 14-day tracking test: eat at the calculated level, monitor your 7-day weight average, and adjust by 100 to 150 calories if it is moving. Use the TDEE Calculator to get the most accurate starting estimate based on your current stats.
Use Maintenance as a Diet Break
After 8 to 12 weeks of a calorie deficit, spending 1 to 2 weeks at maintenance resets leptin and ghrelin, restores NEAT, and rebuilds training performance before the next cut. Diet breaks prevent the metabolic adaptation that makes long, uninterrupted deficits progressively less effective. Calculate your deficit with the Calorie Deficit Calculator so you know the exact gap between your maintenance and your cut.
Bridge Between Bulk and Cut
Returning to maintenance between a bulk and a cut allows your body to stabilize at its new weight, reassess body composition, and plan the next phase without carrying extra water retention or metabolic suppression from either extreme. Split your maintenance calories into the right protein, carbohydrate, and fat targets with the Macro Calculator to make the most of the bridging phase.
What Are the Best Tips for Eating at Maintenance?
Six habits that make maintenance practical and sustainable rather than a guessing game.
- 1
Run the 14-day verification test before trusting the formula
because individual variation means the calculated number can be off by 100 to 300 calories, and confirming it with real data prevents months of incorrect tracking
- 2
Track your 7-day weight average instead of daily weight
because daily scale readings bounce 1 to 3 kilograms from water, sodium, and food volume, while the weekly average reveals whether your weight is actually stable
- 3
Hit your protein target every day even at maintenance
at 1.6 to 2.2 grams per kilogram of body weight, because adequate protein preserves lean mass and keeps metabolic rate from drifting downward over time
- 4
Keep training consistently during maintenance phases
because stopping exercise during a maintenance phase drops TDEE within weeks and turns what should be a stable weight phase into an unintended surplus
- 5
Use maintenance between diet phases rather than jumping straight to the next cut or bulk
because the 4 to 8 week break resets hunger, performance, and motivation so the next phase starts from a stronger position
- 6
Recalculate every 4 to 6 weeks if your training or lifestyle changes significantly
because a new job, a new training program, or a 3 to 5 kilogram weight shift all move your real maintenance number enough to matter
Frequently Asked Questions About Maintenance Calories
Quick answers to the questions people ask most.
Your maintenance calories are the number of calories you need to eat each day to keep your body weight stable over time. They are the same as your Total Daily Energy Expenditure. Eat at maintenance and your 7-day average weight holds steady. Eat below it and you lose weight. Eat above it and you gain.
