Maintenance Calorie Calculator
Use this maintenance calorie calculator to estimate your BMR and TDEE, then turn that into a realistic daily maintenance calorie target. The tool uses the Mifflin-St Jeor equation and a standard activity multiplier table.
This is a planning estimate, not a medical recommendation. Real maintenance calories can vary based on muscle mass, metabolism, training volume, and how accurately activity level reflects your week.

Review before using this maintenance calorie calculator result
- Use an activity level that reflects your normal week, not your best week.
- Track your body weight trend for 2 to 3 weeks and adjust if the estimate is off.
- Maintenance calories for athletes, very lean users, or high-step jobs can differ from formula-only estimates.
How this maintenance calorie calculator works
- The calculator estimates BMR with the Mifflin-St Jeor equation.
- It multiplies that number by the selected activity level to estimate TDEE.
- Your TDEE is used as the maintenance calorie estimate.
- The page then shows simple cut and lean-gain targets around maintenance.
A maintenance calorie calculator is useful when you want a starting target for body recomposition, weight stability, slow fat loss, or a small lean-gain phase. It is not a guarantee of what your body will do every day, but it is a practical first estimate.
Why maintenance calories and TDEE are closely linked
Maintenance calories are the calories that roughly keep your body weight stable over time. TDEE, or total daily energy expenditure, is the model most people use to estimate that number. A maintenance calorie calculator does not measure your metabolism directly. Instead, it uses body stats plus an activity multiplier to estimate the calories you are likely burning in an average day.
This is why a maintenance calorie calculator is best used with a short real-world check. If body weight trends up for two weeks, your real maintenance calories may be lower than the estimate. If body weight trends down, maintenance may be higher.
Activity level reference
| Level | Multiplier | Use this when |
|---|---|---|
| Sedentary | 1.2 | Little structured exercise and mostly seated work. |
| Lightly active | 1.375 | Some walking plus 1 to 3 workouts each week. |
| Moderately active | 1.55 | Regular training or a consistently active routine. |
| Very active | 1.725 | Hard training most days or a physical job plus workouts. |
Examples
When this maintenance calorie calculator is useful
Body-weight maintenance
If you want to hold your current body weight while training or recovering from a cut, a maintenance calorie calculator gives you a starting calorie target you can monitor and fine-tune with scale trends.
Slow fat-loss setup
Many users first estimate maintenance calories, then choose a light or moderate cut target instead of guessing an intake that is too aggressive to sustain.
Lean-gain planning
When a user wants to add muscle without a large surplus, maintenance calories are the reference point for a smaller lean-gain target rather than a random bulk number.
Macro planning
Coaches and self-directed lifters often use a maintenance calorie calculator before deciding protein, carbohydrate, and fat splits because daily calories set the frame for those macro targets.
Limitations and review notes
- This maintenance calorie calculator estimates calories from a formula, not a lab measurement.
- Activity multipliers are broad categories, so users often need a 2 to 3 week adjustment period.
- High-muscle, endurance, or shift-work users may see a bigger gap between the estimate and real maintenance calories.
- Medical, recovery, and nutrition decisions should be reviewed with a qualified professional when needed.
Privacy and processing notes
This maintenance calorie calculator runs in the browser. Your inputs are used to compute the estimate on the page and are not uploaded for account creation or meal-plan storage.
FAQ
Common maintenance calorie calculator questions
Maintenance calories are the calories that roughly keep body weight stable over time, assuming average food logging and average weekly activity.
Almost always, yes. A maintenance calorie calculator usually estimates TDEE, then uses that TDEE number as your maintenance calorie target.
Choose the level that matches your normal week, including steps, job demands, and regular training. Overstating activity is one of the most common reasons maintenance calories look too high.
Formulas simplify metabolism. Sleep, stress, diet adherence, training volume, muscle mass, and the accuracy of your weight trend can all shift the real maintenance calorie number.
Not necessarily. Many people use the maintenance calorie calculator result as a weekly average target and allow some day-to-day variation.
No. The tool is for planning and education. If calorie intake is tied to a medical condition, eating disorder history, or supervised nutrition plan, use professional guidance.
