The calories to maintain weight equal your TDEE, the total you burn in a day. This tool is free with no sign-up and no ads. Eat that amount and your weight tends to hold steady over time. It is the anchor point for any nutrition plan you build.
Your maintenance calories come from your BMR times an activity multiplier. That product is your total daily energy expenditure. Knowing this number keeps you from guessing at portions. It gives a clear centre point for losing, gaining, or holding steady.
This page explains how to find and use the figure. It is free with no account and no ads. You can test different activity levels in seconds. A good tdee calculator turns the whole calculation into one quick answer.
What maintenance means
Maintenance is the calorie level where intake matches output. Eat this amount and your weight stays roughly flat. It sits at the centre of the fat loss and muscle gain scale. Everything else is simply a step above or below it. That is why finding it first makes sense.
These maintenance calories equal your TDEE exactly. Eat below it and you tend to lose weight over time. Eat above it and you tend to gain. Maintenance is the balance point between those two directions. Understanding this makes every goal clearer.
Why the scale still bounces
Your body is not a perfect ledger, though. Water, food weight, and hormones cause daily swings. So judge whether you maintain weight over weeks, not single days. A one-day jump on the scale rarely means real change. The trend is what matters.
The figure is personal to you and your body. Two people of the same weight can differ by hundreds of calories. Activity level and muscle mass explain most of that gap. This is why a personal estimate beats a generic table. It reflects how you actually live.
Treat it as a starting point
Because it is an estimate, expect to fine-tune it. The formula gives a strong starting point, not a final answer. Real weight trends then confirm or adjust the number. Give any target a few weeks before judging it. Then let your data guide the next step.
Using it between diet phases
Maintenance is also useful between diet phases. Eating at it gives your body a steady break. That can make the next push easier to sustain. It is not wasted time at all. A planned hold has real value.
Knowing your maintenance also curbs guesswork at meals. You stop wondering if a portion is too much. The number gives a clear reference point. Meals become decisions, not gambles. That alone reduces a lot of stress.

Finding your number
Start with your BMR from the Mifflin-St Jeor formula. It uses your height, weight, age, and sex. This is your resting burn before any movement is added. It forms the base of the whole calculation. Everything builds on top of it.
Applying the multiplier
Next, choose an activity multiplier from 1.2 to 1.9. Multiply your BMR by that chosen value. The result is your TDEE, which equals your calories to maintain weight. Picking the honest level here is what makes the figure fit. An inflated level throws the estimate off.
For example, a BMR of 1,500 at a 1.4 multiplier gives about 2,100. That figure is illustrative only. Your own inputs will produce a different total. The example simply shows the two-step method. In practice the tool handles both steps for you.
A tdee calculator does this in a single step. You enter your details, pick a level, and read the number. There is no need to work the formula by hand. That saves time and avoids simple arithmetic slips. The result appears the moment you finish.
Round the result to a tidy figure to make tracking simple. An estimate near 2,100 is easier to follow than an exact decimal. Precision beyond that adds very little value. Your day-to-day intake naturally varies anyway. A clean round number keeps the plan practical.
Compare it against a normal week
It helps to log a normal week of eating too. Compare your usual intake against the estimate. If your weight is steady, your true maintenance is close. That real-world check strengthens the number. It grounds the formula in your actual habits.
Do not stress over hitting the figure exactly each day. Aim for the weekly average instead. Some days will run high and some low. That is completely normal. The average is what shapes your weight.
Adjusting over time
Your maintenance calories are not fixed for life. They shift as your weight, muscle, and activity change. A number that fit last year may be off today. This is normal and expected. A quick refresh keeps the target accurate.
Track your weight across two or three weeks. If it holds steady, your estimate is right. If it climbs or falls, adjust intake by 100 to 200 calories. Small changes are usually enough to correct the drift. Big swings are rarely needed.
Use a weekly average rather than a single reading. Daily weight bounces around for many reasons. The trend line is what really matters here. Water and food weight can mask true progress. Averaging smooths out the noise.
Recalculate after a big change in weight or routine. A new job or training block can move your maintenance calories. A quick refresh keeps the target honest and current. It only takes a moment with the tool. Then you can carry on with confidence.
Treat every figure as a guide, not a promise. Bodies vary, and formulas rely on averages. Real results always win over a calculation alone. Let your weight trend have the final say. That habit keeps the plan grounded in reality.
Seasons and stress can move the number too. A busy summer may raise your activity. A quiet winter may lower it. Checking in now and then catches these shifts. It keeps you eating for your current life.
It falls as you lose weight
As you lose weight, expect maintenance to fall. A smaller body needs fewer calories to run. So refresh the figure after real progress. This prevents an unexpected stall. It keeps results moving in the right direction.

Frequently Asked Questions
How many calories maintain my weight? Your calories to maintain weight equal your TDEE. Multiply your BMR by an activity level from 1.2 to 1.9 to find the figure.
Are maintenance calories the same as TDEE? Yes. Maintenance calories and TDEE describe the same figure, the total you burn in a day. Eating that amount tends to hold your weight steady.
Why is my number different from a friend's? Activity, muscle mass, height, and age all differ. Two people of the same weight can have maintenance calories that vary by several hundred.
How often should I recalculate? Refresh the number after a notable weight change or a new routine. Otherwise, a check every month or two keeps it accurate enough.
