Protein Intake Calculator
Estimate daily protein from grams per kilogram, average protein per feeding, protein-associated energy, and the signed gap from current intake. The dedicated meal distribution view shows how the target could be divided without implying that every meal must be identical.

Daily protein target and meal distribution
Daily protein target and meal distributionCurrent intake is compared with the weight-based target, then the target is divided into the entered number of equal meal references.
Exact scenario comparisonProtein target (g/kg/day) changes while all other entered assumptions remain constant.

How to use Protein Intake Calculator
- Enter current body weight and a protein rate appropriate to the purpose and any professional guidance.
- Enter the number of regular meals or feedings to obtain a simple average distribution reference.
- Compare current intake with the target and adjust food choices gradually while considering total energy, tolerance, kidney health, and overall diet quality.
Calculator guide
Understanding Protein Intake Calculator
Protein targets are commonly expressed relative to body weight, then translated into a daily total and a practical amount per meal. This calculator keeps the target, current intake, and meal distribution separate.
Calculation method
How the calculation works
Multiply body weight by the entered grams-per-kilogram target and distribute the result across the selected number of meals. Multiply body weight by the entered grams-per-kilogram rate for the daily target, divide by number of feedings for an even-distribution reference, multiply grams by 4 kcal/g, and subtract current intake from target.
Food planning
Closing a protein gap without losing diet quality
The target is most useful when it can be met with foods that fit the full eating pattern.
Worked situations
Practical examples
- At 72 kg and 1.6 g/kg/day, the calculated daily protein target is 115.2 g.
- Across four feedings, an even-distribution reference is 28.8 g per feeding.
- If current intake is 95 g, the displayed gap is +20.2 g/day and the target represents about 461 kcal.
Better inputs
Useful tips
- Use a rate chosen for the actual context—general nutrition, aging, calorie restriction, endurance, or resistance training can differ.
- Treat per-meal protein as a distribution aid, not a hard absorption ceiling.
- Consider protein source quality, digestibility, allergies, preferences, and total food pattern rather than grams alone.
Before relying on the result
Limitations and common mistakes
- The calculator does not diagnose deficiency or choose a safe target for kidney, liver, metabolic, pregnancy, or other medical conditions.
- Using total body weight may overstate or understate needs in some body-composition contexts.
- Even division across meals is a convenience; meal timing and dose-response depend on age, training, energy intake, and individual factors.
Reference
Key terms
- g/kg/day
- Daily protein grams assigned for each kilogram of entered body weight.
- Feeding
- Meal or eating occasion used to distribute the daily protein target.
- Protein gap
- Calculated target minus entered current daily intake.
- Protein quality
- Digestibility and essential-amino-acid characteristics of a protein source.

Frequently asked questions
Is more protein always better?
No. Benefit depends on context, and excessive intake can displace other nutrients or be inappropriate for some medical conditions.
Can the body absorb more than the per-meal number?
The body can digest and absorb larger amounts. The displayed value is only an even distribution reference.
Should I use goal weight instead of current weight?
That depends on the chosen guideline and individual context; obtain professional guidance when body composition or medical conditions make the basis important.
Does the calorie result mean protein adds extra calories?
It shows energy represented by the target. Those calories are part of the total diet, not automatically additional.
