Enter age, sex, height, weight, and activity level to estimate calories needed to maintain weight.
Maintenance calories are the estimated calories needed to keep your current weight stable at your current activity level.
Maintenance calories guide
What maintenance calories are
Maintenance calories are the estimated calories needed to keep your current weight roughly stable. They are not a perfect daily number, but they are the most practical reference point for diet planning.
Energy balance
Calories in vs calories out
Weight changes when intake and energy use are not in balance over time. Maintenance calories sit near the middle point, while a deficit or surplus moves you away from that baseline.
Activity
How activity level affects calories
Two people with the same height and weight can need very different calorie intakes if one is sedentary and the other trains or moves a lot. Activity level is the reason maintenance estimates can change so much.
Goals
Maintenance vs deficit vs surplus
Maintenance keeps weight broadly stable, a deficit is used for weight loss, and a surplus is used for weight gain or muscle-building goals. Knowing the maintenance number makes those decisions much clearer.
Planning
How to use maintenance calories day to day
You can use the estimate as a starting point, then compare it with real-world weight trends and how you feel. If weight changes faster or slower than expected, the maintenance estimate may need a small adjustment.
Comparisons
Why maintenance is different from calorie calculator results
A general calorie calculator may show maintenance alongside fat-loss and muscle-gain targets. This page focuses on the maintenance baseline so the result is easier to use when you only want to hold weight steady.
Limitations
When to adjust the estimate
Changes in training, job activity, sleep, body composition, and routine can all move maintenance over time. That is why a good estimate should be checked again when your lifestyle changes.
Examples
Real-life maintenance examples
A person who trains lightly and works at a desk may need fewer calories than someone with the same body size who is on their feet all day. That is why the maintenance calories calculator is a better baseline than guessing from body size alone.
Common mistakes
Common mistakes when planning maintenance
A common mistake is using the first estimate forever without checking it against weight trend and routine changes. Another is confusing maintenance with a weight-loss target, which can make the plan feel unnecessarily restrictive.
