Weekly Protein Calculator
This calculator converts a body-weight-based protein target into daily and weekly amounts, then compares that target with seven entered intake values. It is useful for meal planning and checking consistency across the week.
The grams-per-kilogram factor is user controlled because appropriate intake depends on age, training, energy intake, health, and professional advice.

Daily target = body weight × protein factor
Weekly target = daily target × 7
Difference = logged total − weekly target
What the result means
The main result is the planned seven-day protein amount based on the chosen factor.
People with kidney disease or other medical conditions should obtain individualized advice.
Given: 75 kg and 1.6 g/kg/day.
Calculation: 75 × 1.6 = 120 g/day; 120 × 7 = 840 g/week.
Result: Weekly target is 840 g.
Should I use current or goal weight?
Use the basis recommended for your plan; current weight is the simplest default.
Is plant protein counted differently?
Count grams as listed, while recognizing protein quality and meal composition can differ.
Do I need the same amount every day?
The weekly total can allow variation, though distribution across meals may also matter.
Can the factor be too high?
Yes. More is not automatically beneficial and may be inappropriate for some people.
Why compare weekly intake?
A weekly view shows consistency and reduces focus on one unusual day.
