Use this maintenance calorie calculator to estimate how many calories you need each day to maintain your current weight. Enter your age, sex, height, weight, and activity level to get a practical calorie maintenance starting point you can refine from your real-world weight trend.
Use your normal routine, not your best day or your most disciplined week. A maintenance calorie calculator works best when the inputs reflect your real life.
This maintenance calorie calculator is designed for adults and gives an estimate, not a medical prescription.
You will see your estimated maintenance calories, resting calories, and simple starting targets for fat loss and muscle gain.
This quick chart helps you see how a moderate fat-loss target, maintenance calories, and a mild muscle-gain target relate to each other.
Use this table to see how each daily calorie target changes from maintenance calories and what each target is generally best for.
| Goal | Daily calories | Change vs maintenance | Best for |
|---|---|---|---|
| Fat loss target | -- | About 15% below | A moderate deficit when you want a more sustainable fat-loss starting point. |
| Maintenance calories | -- | Baseline | Holding your current body weight while you monitor your real-world trend. |
| Muscle gain target | -- | About 10% above | A mild surplus when training is consistent and you want controlled gain. |
Your maintenance calories should be treated as a starting estimate and then adjusted from your real trend.
Maintenance calories are best used as a starting point. Your true calorie maintenance may differ with routine changes, hidden intake, and day-to-day activity variation.
This page answers the core question first: how many calories should you eat to maintain your weight right now.
The calculator uses a Mifflin-St Jeor style resting calorie estimate and then applies your selected activity multiplier.
You also get practical starting targets for fat loss and muscle gain so your maintenance calories become easier to use.
Use your maintenance calories to sanity-check everyday meals.
Simple meals are usually easier to compare against your target.
A maintenance calorie calculator helps you spot when one meal swings high.
A strong maintenance calorie calculator should do more than throw out a number. It should explain where that number comes from, what affects it, and why your calorie maintenance can shift with life changes. In practical terms, maintenance calories are your best estimate of the calories you need to keep your body weight stable. That estimate usually begins with resting needs and then layers daily movement on top.
The first step in a maintenance calorie calculator is estimating how much energy your body uses at rest. This is often described as BMR or resting calorie needs. Larger bodies usually burn more at rest than smaller bodies, while age and sex can also change the estimate. That is why your height, weight, age, and sex belong in the calculator before activity is added.
Once resting calories are estimated, the calculator applies an activity multiplier. This is where maintenance calories become more personal. A desk worker who trains lightly a few times per week will usually need fewer calories than someone who stands all day, walks often, and trains hard. A good maintenance calorie calculator makes this step visible because activity level is one of the biggest reasons estimates differ.
Even the best maintenance calorie calculator is still a starting point. Real life adds noise: restaurant portions, weekends, hidden oils, seasonal routine changes, and differences in non-exercise movement. If your average scale trend rises or falls over a few weeks, your real maintenance calories are probably a little higher or lower than the estimate. That is why the number works best when paired with consistent tracking and calm adjustments.
For adults, this page uses a Mifflin-St Jeor style resting calorie estimate and then multiplies it by the selected activity level. That gives you a practical TDEE-style maintenance calorie estimate.
Different websites may use different formulas, rounding rules, or activity definitions. That is why two maintenance calorie calculator results can be close but not identical.
If people get a maintenance calorie calculator result wrong, activity level is often the reason. Pick the option that describes your full week, not just your hardest workout day.
Mostly sitting with very little intentional exercise.
Choose inactive if you spend most of the day seated and do not add much purposeful movement beyond normal daily tasks. This setting generally fits people whose work is desk-based and whose exercise is rare or inconsistent.
Example: Office work, driving, and only occasional short walks.
Some walking or light exercise during the week.
Choose low active if you move more than the average desk worker but still spend a lot of time sitting. This often fits people who walk daily, train lightly, or include a few moderate sessions per week without a highly active job.
Example: Several thousand steps per day plus 2 to 3 moderate workouts.
Consistent training and a fairly active routine.
Choose active if you exercise regularly and your weekly movement is clearly above average. This level fits many people who combine gym sessions, sports, or cardio with a generally mobile lifestyle and do not spend every day almost completely sedentary.
Example: Structured exercise most days plus a moderate-to-high daily step count.
Hard training, physical work, or both.
Choose very active if you combine demanding workouts with a highly mobile or physically demanding routine. This is usually not the average user. If you are unsure whether you qualify, start one level lower and adjust from your weight trend rather than overestimating maintenance calories.
Example: Manual labor, high daily movement, and frequent intense training.
Use your maintenance calorie calculator result as a starting intake target, not a final truth. Aim for a repeatable routine for at least 2 weeks so you can see whether your average weight is stable, rising, or falling.
Water retention, sodium, digestion, and menstrual cycle changes can move the scale day to day. Maintenance calories should be judged from a weekly average trend. That is the only way to know whether your calorie maintenance estimate is truly close.
If your weight is trending up, trim your daily calories slightly. If your weight is trending down, add a little more. Small adjustments of about 100 to 200 calories are usually easier to evaluate than dramatic changes.
One reason people search for a maintenance calorie calculator is that maintenance calories sit in the middle of every other goal. Once you know roughly where maintenance lives, it becomes easier to plan a deficit for fat loss or a surplus for muscle gain without guessing from scratch every week.
If your goal is to hold your current body weight, start near your maintenance calorie calculator result and stay consistent. This is useful after dieting, during a performance phase, or anytime you want a clearer read on your real appetite and routine.
Best use: A stable routine where you want to keep progress without pushing hard in either direction.
Once you know calorie maintenance, fat loss becomes more practical. Most people do better with a moderate deficit than an aggressive one because energy, training quality, and hunger stay more manageable. That is why this page shows a moderate fat loss starting point instead of promising a crash-diet number.
Best use: When you want a realistic calorie target that still leaves room for adherence.
A muscle-gain phase usually starts just above maintenance calories, not massively above them. A mild surplus can help support training and recovery while keeping weight gain more controlled. For many people, a maintenance calorie calculator makes bulking calmer because the surplus starts from a logical baseline.
Best use: When training is consistent and you want a more measured gain phase.
This page helps you estimate your daily target. The next step is checking real meals against that number. Use the main AI food tool to upload a meal photo, estimate calories, and see whether your intake looks close to your maintenance range.

Maintenance calories are the estimated calories you need each day to keep your current body weight roughly stable. In practical terms, they represent your estimated daily energy expenditure after resting needs and activity are both considered.
Usually, yes. In everyday nutrition content, maintenance calories and TDEE are used almost interchangeably. Both describe the calories you likely need to maintain your current weight before you intentionally move into a deficit or surplus.
A maintenance calorie calculator is best understood as a starting estimate. It can be very useful for planning, but your true calorie maintenance may be a little different because of muscle mass, daily movement, hidden food intake, and week-to-week routine changes.
Different tools may use different equations, activity multipliers, or rounding rules. Even when two calculators both estimate maintenance calories, small formula differences can change the result by a modest amount. That is why your real trend matters more than comparing one number against every site online.
Choose the activity level that reflects your normal week, not your best day. If you are torn between two options, start with the lower one and adjust from your weight trend over the next 2 to 4 weeks. That approach is usually safer than overestimating maintenance calories right away.
If your average body weight stays roughly stable for a few weeks while your intake is consistent, your maintenance calories are probably close. If your average trend rises, your real maintenance is likely a bit lower than estimated. If your average trend falls, it is likely a bit higher.
Not necessarily. Many people maintain weight just fine with small day-to-day variation as long as their weekly average intake stays close to maintenance calories. Consistency matters more than perfection. The goal is to stay close enough that your overall trend remains stable.
This maintenance calorie calculator is designed for adults and general planning. It should not replace individualized medical guidance for pregnancy, breastfeeding, younger users, eating-disorder recovery, or health conditions that significantly affect metabolism or nutrition needs.
