Going from TDEE to macros means splitting your daily calories into protein, carbs, and fats. This tool is free with no sign-up and no ads. First you find your calorie target, then you divide it into grams. That gives a plan you can actually shop for and follow.
Your TDEE is the total energy you burn across a day. A macro calculator turns that number into three daily gram targets. Protein carbs fats each carry a set number of calories per gram. Knowing those values makes the split straightforward.
This page shows the tdee to macros steps in plain words. It is free with no account and no ads. You can adjust the split to suit your goal. A good tdee calculator makes the whole process quick and clear.
Setting protein
Protein comes first because it protects your muscle. A common target is 1.6 to 2.2 grams per kilogram of body weight. Active people and dieters sit at the higher end of that range. Setting this first anchors the rest of the plan. It is the most important macro to hit.
For an 80 kg person, that is roughly 128 to 176 grams a day. These figures are illustrative only. Your own weight and goal set the real number. A leaner target suits a fat loss phase. A steady one suits maintenance.
Turning grams into calories
Each gram of protein holds about 4 calories. So 160 grams supplies around 640 calories. That block comes off your total before you set the rest. Knowing the calorie cost keeps the split accurate. It stops the numbers from drifting.
Protein also keeps you feeling full, which helps in a deficit. Spreading it across your meals supports muscle repair. This is exactly why the tdee to macros process starts here. A steady protein intake steadies your appetite too. That makes any diet easier to hold.
Building up to the target
If a target feels high at first, build up slowly. Add a portion at each meal until you reach the range. Consistency matters far more than a perfect daily figure. Hitting the range most days is enough. Do not stress over a single low day.
Where to get your protein
Good protein sources make the target easier to reach. Lean meat, fish, eggs, dairy, and beans all help. Spreading them across meals keeps intake steady. It also improves fullness through the day. Variety keeps meals interesting too.
Protein needs can rise a little when you train hard. More muscle work means more repair. The upper end of the range then makes sense. So lean toward it during heavy phases. That supports recovery and growth.

Carbs & fats split
After protein, you split the remaining calories between carbs and fats. Both are useful, so balance beats cutting either to zero. Preference and performance guide the mix. There is no single correct ratio. You choose what suits your training and taste.
Why fat has a floor
Fat should not drop too low, as it supports your hormones. A floor near 0.6 to 0.8 grams per kilogram is sensible. Each gram of fat holds about 9 calories. That higher calorie density means fat adds up fast. A small amount covers a lot of energy.
Carbs fuel training and fill the rest of your budget. Each gram of carbohydrate holds about 4 calories. Active people often place more of the total here. Carbs support harder sessions and recovery. They are not the enemy many fear.
Say 700 calories remain after protein and a fat floor. Putting that into carbs gives about 175 grams. This is how protein carbs fats fit into one total. Each macro simply claims its share of the calories. The three targets then add up to your TDEE.
There is no single perfect split for everyone. A macro calculator lets you test options quickly. Pick the mix you can follow on most days. Adherence beats an ideal ratio you cannot sustain. The best split is the one you actually keep to.
Do not forget fibre
Fibre deserves a mention within your carbs. Whole grains, fruit, and vegetables keep you full. They also support steady energy and digestion. So favour quality carb sources where you can. Your appetite and health both benefit.
Fats can come from oils, nuts, and oily fish. These bring useful nutrients alongside energy. Keeping a mix of sources is sensible. It supports hormones and general health. Balance across the day works best.
Example
Take a TDEE of 2,400 calories for maintenance. We will divide it into protein carbs fats. This example uses round numbers for clarity. Your own figures will differ. The steps stay exactly the same.
Set protein at 160 grams, which is 640 calories. Set fat at 70 grams, which is 630 calories. Together they use 1,270 calories of the total. That leaves the remainder for carbohydrate. The split is already taking shape.
That leaves 1,130 calories for carbs. Dividing by 4 gives about 282 grams of carbohydrate. Your daily plan is now three clear targets. You can shop and cook against those numbers. That is far easier than counting calories alone.
For fat loss, drop the total first, then resplit. A tdee calculator paired with a macro calculator makes that easy. Protein usually stays high while carbs fall. Fat holds near its floor to protect hormones. The plan adjusts cleanly to the new total.
Treat these grams as targets, not exact rules. Hitting them most days is what really counts. Adjust as your weight and energy respond over time. A short run of data tells you if the split works. Then you fine-tune from there.
Adjusting for a bulk
For a bulk, add the surplus mostly to carbs. Extra carbs fuel bigger training sessions. Protein stays high to build muscle. Fat holds around its usual share. The same three-step method still applies.
You can also shift carbs toward training days. More on hard days, fewer on rest days works well for some. The weekly total stays the same either way. This is optional, not required. Simplicity is fine if you prefer it.

Frequently Asked Questions
How do I turn TDEE into macros? Set protein first, then a fat floor, and fill the rest with carbs. Protein and carbs hold about 4 calories per gram, and fat about 9.
How much protein should I aim for? A common range is 1.6 to 2.2 grams per kilogram of body weight. Dieters and active people usually sit at the higher end of it.
Is there one perfect macro split? No. Once protein and a fat floor are set, the carb and fat balance is flexible. Choose a mix you can follow on most days.
Are these macro targets exact? No. They are estimates from your calorie total. Hit them most days, then adjust as your weight and energy respond over time.
