Daily protein requirement calculator
NNWA's protein calculator turns your weight and goal into a daily protein range in grams. It uses the Indian Council of Medical Research's National Institute of Nutrition (ICMR-NIN) allowance of about 0.83 grams per kilogram for general health, and sports-nutrition ranges of 1.2 to 1.6 and 1.6 to 2.2 grams per kilogram for regular exercise and muscle gain.
Enter your weight in kilograms, choose your goal, and this calculator gives you a daily protein range in grams. It offers a range rather than a single number because that is how the evidence actually reads. For general health, the anchor is the recommended dietary allowance from the ICMR-NIN Dietary Guidelines for Indians: about 0.83 g of protein per kilogram of body weight each day. If you train regularly or lift weights, your range shifts upwards.
The Indian context matters because a typical plate here leans on cereals (rice, roti), which supply energy generously and protein modestly. It is easy to eat a full day's meals and still fall short of even the baseline allowance. Knowing your number is the first step; the second is meeting it from foods already in your kitchen: dal, chana, rajma, paneer, curd, eggs, fish, soya and groundnuts.
Daily protein: grams per kilogram
Daily protein
77 to 102g
1.2 to 1.6 g per kg. The range for recreationally active adults.
Everyday Indian sources: dal, chana, rajma, paneer, curd, eggs, fish, soya and groundnuts. Cereal-heavy plates usually need one of these added deliberately at each meal.
These ranges are for healthy adults. Anyone with a kidney condition, or advised to restrict protein, should set intake with their doctor. More is not better past the range that suits the goal.

The calculator multiplies your body weight in kilograms by a range matched to your goal. For general health, it uses 0.8 to 1.0 g of protein per kg of body weight, a band built around the ICMR-NIN recommended dietary allowance for Indian adults, which is about 0.83 g per kg per day. For people who exercise regularly, it uses 1.2 to 1.6 g per kg. For strength training and muscle gain, it uses 1.6 to 2.2 g per kg, the consensus range in sports-nutrition practice.
Worked through, a 60 kg adult aiming at general health lands between 48 and 60 g of protein a day; the same adult training seriously for muscle would be looking at 96 to 132 g. The output is deliberately a range, not a point. Where you sit within it depends on age, training load and the rest of your diet.
02Why Indian plates often under-deliver
The everyday Indian plate is anchored by cereal (rice, roti, or both), with everything else arranged around it. Cereals carry some protein, but a diet that draws most of its calories from them tends to under-deliver, which is why many people who feel they eat well still sit below their calculated range. The correction rarely requires anything exotic. Dal, chana and rajma bring plant protein; paneer and curd add dairy protein; eggs and fish offer some of the most complete protein available; soya is unusually dense for a plant food; and groundnuts make a useful snack. Pairing a cereal with a pulse (dal with rice, for instance) also improves the overall quality of the protein you absorb.
03Read it alongside your other numbers
A protein target is one number in a larger picture. If you are managing your weight, start with energy: the calorie calculator estimates your daily needs, and the TDEE calculator shows how activity moves them. With calories and protein both settled, the macro calculator divides what remains between carbohydrate and fat. That order (energy first, protein second, the rest third) is close to how a working nutrition coach actually builds a plan.
04What this calculator cannot tell you
The calculator knows two things about you: your weight and your goal. It does not know your age, whether you are pregnant or breastfeeding, how much of your weight is muscle, or whether a medical condition changes the arithmetic. If you carry a significant amount of excess weight, a per-kilogram formula applied to your current weight can overstate your needs. And one caution outweighs the rest: anyone with a kidney condition or reduced kidney function should not push protein towards the higher ranges without medical guidance. Protein in kidney disease is a specialised subject (NNWA's renal nutrition programme exists for exactly this territory), and it is one place where a calculator must give way to a doctor.
05What a practitioner does with these numbers
A calculator hands you a range; a practitioner turns it into meals. That means translating grams into servings of dal, paneer and eggs, spreading protein across the day rather than crowding it into dinner, adjusting for a vegetarian kitchen or a modest food budget, and revising the target as training, age and health change. For anyone working with athletes or serious gym-goers (the territory of the 1.6 to 2.2 g per kg range), NNWA's sports nutrition programme goes into the depth a calculator cannot: how much, when, and from which foods. The broader craft of assessing a client and building a complete plan sits in the diploma programme. Both are skill-enhancement certificate programmes: they prepare you to plan diets and coach clients, not to practise clinical dietetics or claim dietitian registration.
This calculator gives a screening figure for healthy adults: a starting point, not a diagnosis or a prescription. It cannot account for pregnancy, breastfeeding, kidney disease, diabetes or other medical conditions. If any of these apply to you, or if you are planning a major change in diet, consult a doctor or a qualified nutrition professional first.
What people ask about the protein calculator
Expand any question to read the answer in full.
How much protein does an Indian adult need per day?
The ICMR-NIN Dietary Guidelines for Indians set the recommended dietary allowance at about 0.83 g of protein per kilogram of body weight per day for adults. For general health, a practical band is 0.8 to 1.0 g per kg. People who exercise regularly need more (roughly 1.2 to 1.6 g per kg), and strength trainees more still.
Can vegetarians meet their protein needs on an Indian diet?
Yes, though it takes deliberate planning. Dal, chana, rajma, soya, paneer, curd and groundnuts are all substantial vegetarian sources, and pairing a cereal with a pulse (rice with dal, roti with chana) improves protein quality. The common problem is portion size: a small bowl of dal beside a large plate of rice supplies far less protein than most people assume.
Is too much protein harmful for the kidneys?
For healthy adults, intakes within the ranges this calculator produces are generally considered safe. The caution applies to people with an existing kidney condition or reduced kidney function, for whom high protein intakes can add strain. They should set protein targets only with medical guidance. If you have any kidney diagnosis, speak to your doctor before increasing protein.
Why does the calculator give a range instead of one number?
Because the underlying evidence gives ranges. Protein needs vary with training load, age, body composition and the rest of the diet, so honest guidance sets a band: 0.8 to 1.0 g per kg for general health, up to 1.6 to 2.2 g per kg for muscle gain. Start near the lower end of your band and adjust based on how you recover and progress.
Do I need protein supplements to reach my target?
Usually not. Most daily targets can be met from ordinary foods (eggs, fish, dal, chana, rajma, paneer, curd, soya and groundnuts) spread across meals. Supplements are a convenience, not a requirement: they matter mainly when appetite, time or a very high training target makes food alone impractical. Get the food pattern right first, then decide whether a supplement adds anything.
Should I enter my current weight or my target weight?
Use your current weight. The ranges are expressed per kilogram of actual body weight, and the calculator applies them that way. The one caveat: if you carry a lot of excess weight, the result may overstate your needs, because fat tissue needs less protein than muscle, a reason to treat the figure as a starting point rather than a prescription.
