A TDEE calculator estimates the total calories your body burns in a day. This tdee calculator is free with no sign-up. It combines your resting burn with your activity level. You get a clear daily number. You can plan your diet around it.
Your total daily energy expenditure is the foundation of any calorie plan. It tells you roughly what you burn each day. To calculate tdee, the tool uses your body details and activity. That gives a personal estimate. It beats a generic guess.
The tool works in metric and imperial units. You can enter kilograms and centimetres or pounds and inches. Everything is free, with no account and no ads. This tdee calculator free of charge is ready anytime. There is nothing to sign up for.
What is TDEE
TDEE stands for total daily energy expenditure. It is the total calories you burn across a full day. That includes resting functions, daily movement, and exercise. So it captures your whole energy use. It is the number that matters for diet.
TDEE starts from your basal metabolic rate, or BMR. Your BMR is what you burn purely at rest. It powers breathing, circulation, and cell repair. TDEE then adds the energy of moving around. Activity lifts the resting figure.
The link between the two
The link is simple: TDEE equals BMR times an activity multiplier. A sedentary person uses a small multiplier. A very active person uses a large one. That single step scales rest into a daily total. It is the core of the calculation.
For BMR, the tool uses the Mifflin-St Jeor equation. For men it is 10 times weight in kg, plus 6.25 times height in cm, minus 5 times age, plus 5. For women it uses minus 161 instead of plus 5. It is a trusted formula.
Once you have BMR, the multiplier finishes the job. It scales the resting figure into a daily burn. That daily burn is your total daily energy expenditure. The tool does both steps for you. You just read the result.
Why BMR dominates the total
BMR is the largest slice of most people's burn. It runs constantly, even in your sleep. So it forms the bulk of the total. Activity adds on top of it. Together they make your TDEE.
The Mifflin-St Jeor equation is trusted for good reason. It tracks real resting burn closely. It uses only weight, height, age, and sex. Those four inputs are easy to supply. The result is reliable.
Small errors shift the result
Small input errors shift the outcome. A wrong weight or age skews the BMR. So enter your details carefully. The tool is only as good as its inputs. Accurate numbers give an accurate burn.
The Mifflin-St Jeor equation suits most healthy adults well. It is the modern standard for estimating resting burn. Older formulas exist, but this one tracks reality closely. So the tool relies on it. The result is dependable for everyday planning.
Your total daily energy expenditure is a living figure. It shifts as your weight and habits change. So it is worth rechecking now and then. A quick update keeps your calorie plan accurate. The tool makes that easy.

Activity levels
Activity multipliers turn your BMR into your TDEE. They range from about 1.2 to 1.9. A sedentary lifestyle uses roughly 1.2. A very active one uses close to 1.9. Your honest activity sets the figure.
It helps to pick your activity level honestly. Overstating it inflates your daily burn. That can quietly stall a diet plan. So when unsure, choose the lower level. An honest figure is a useful one.
Everyday movement counts more than people expect. Walking, chores, and standing all add up. This sits inside the activity multiplier. So a busy day burns more than a still one. The factor captures that difference.
What each level means
Sedentary means little exercise and a desk-based day. That maps to about 1.2 times your BMR. Light activity, with easy exercise a few days a week, is near 1.375. It lifts the multiplier a little. Movement adds up.
Moderate activity means exercise most days. It sits around 1.55. Very active means hard training or a physical job. That reaches roughly 1.725 to 1.9. Each step adds to your daily burn. The scale is steady.
Picking the right level is the most important choice. Overstating your activity inflates your TDEE. That can quietly stall a diet plan. Being honest keeps the number useful. When unsure, choose the lower level.
The tool lets you switch levels and compare. You can see how your daily burn shifts. That helps you find a realistic figure. You can calculate tdee for a few levels. Then you pick the honest one.
Movement outside training
Non-exercise movement adds up more than people think. Walking, chores, and fidgeting all count. This daily activity sits inside the multiplier. So a busy day burns more than a still one. The factor captures that.
Exercise pushes you up the activity scale. A few hard sessions a week lift the level. Daily training lifts it further. So honest training habits set the figure. Do not count workouts you rarely do.
The right level is easy to overstate. Many people pick too high a factor. That inflates the total daily energy expenditure. A padded number stalls a diet. When unsure, drop a level.
Using your number
Your TDEE is your maintenance calorie level. Eating at it should hold your weight steady. Eating below it creates a deficit for weight loss. Eating above it creates a surplus for muscle gain. It anchors every plan.
Turning it into macros
You can also split your TDEE into macros. Protein, carbohydrate, and fat targets flow from the total. That guides not just how much but what to eat. The tool gives the total. You then set the split.
Treat the number as a starting estimate, not a fixed truth. Real burn varies day to day. Track your weight for a couple of weeks. Then adjust your intake if needed. The estimate improves with feedback.
Your TDEE anchors every calorie plan. Maintenance, loss, and gain all flow from it. So it is worth getting right. A careful figure guides good choices. The tool keeps it simple.
Real burn varies from the estimate. Daily activity and metabolism shift things. So use the number as a starting point. Track your weight and adjust. Feedback sharpens the figure over time.
Metric and imperial both work here. Enter kilograms or pounds as you prefer. The tool handles either cleanly. That suits US and UK users alike. Nothing needs converting by hand.
This is an estimate for general guidance only and not medical advice; consult a doctor or a registered dietitian before big diet changes.

Frequently Asked Questions
What is TDEE? TDEE is your total daily energy expenditure, the calories you burn in a full day. It equals your BMR multiplied by an activity multiplier.
How is TDEE calculated? The tool finds your BMR with the Mifflin-St Jeor equation, then multiplies it by an activity factor from about 1.2 to 1.9.
Which activity level should I pick? Choose the one that honestly matches your week. If you are unsure, pick the lower level, since overstating activity inflates your TDEE.
Is the TDEE calculator free? Yes. This tdee calculator free of charge has no sign-up and no ads, and it works in metric and imperial units.
