Turn weight, activity, and goal into a daily protein target
Protein needs vary by body size, training load, and objective. This page uses a simple grams per kg approach, then applies a goal adjustment.
You get a daily gram target plus charts, compare, copy, and a printable PDF layout.

How to use the Protein Intake Calculator
1
Enter your weight
Type your weight and choose kilograms or pounds.
2
Select activity level
Choose from sedentary to very active to set a starting grams per kg value.
3
Select your goal
Maintenance keeps the baseline. Muscle gain and fat loss apply a small adjustment within common ranges.
4
Calculate and compare
Press Calculate to see the daily grams target, charts, scenario compare, and a PDF export layout.

What this tool does
The Protein Intake Calculator estimates daily protein needs from your weight, activity level, and fitness goal.
It converts pounds to kilograms when needed, selects a grams per kg target, then multiplies by body weight to produce a daily grams value.
Protein rich foods can help you meet daily targets
Baseline and ranges
A widely cited baseline for many sedentary adults is 0.8 grams per kilogram of body weight per day.
Practical targets often go higher depending on training and objective.
Baseline: 0.8 g per kg
Common training range: roughly 1.2 to 2.0 g per kg
This page uses a simple max reference of 2.2 g per kg for chart comparison
Activity based needs
More activity can increase protein turnover and repair demand.
Sedentary: 0.8 g per kg
Light: 1.0 g per kg
Moderate: 1.2 g per kg
Active: 1.6 g per kg
Very active: 2.0 g per kg
Goal adjustments
Goals can shift targets slightly. This calculator keeps adjustments conservative and bounded:
Maintenance: uses the activity baseline
Muscle gain: ensures at least 1.6 g per kg, then adds a small bump up to 2.2 g per kg
Fat loss: ensures at least 1.2 g per kg, then adds a small bump up to 1.6 g per kg
Factors that can change your needs
Body size and composition
Heavier bodies generally require more total grams.
For athletes, lean mass can be a useful refinement, but this tool uses total weight for simplicity.
Training type
Strength training often uses higher targets than casual activity.
Endurance training can also raise needs depending on volume.
Age and health context
Older adults and medical conditions can change recommended intake.
If you have kidney disease or other conditions, use professional guidance.
Protein sources
Animal sources
Meat, poultry, fish: roughly 20 to 30 g per 100 g
Eggs: about 6 to 8 g per egg
Dairy: varies by product and serving size
Plant sources
Legumes: roughly 7 to 10 g per 100 g cooked, varies by type
Nuts and seeds: roughly 5 to 7 g per 30 g
Whole grains: modest amounts that add up over a day
Practical tips
Use a consistent weight measurement, especially if comparing scenarios.
Spread protein across meals to make targets easier to hit.
Use the chart view to sanity check how aggressive the per kg target is.
Use the PDF export for a clean shareable summary.
Results are estimates and may differ based on individual metabolism, diet quality, and medical context.
