Protein Calculator
A protein calculator helps you estimate daily protein intake by using body weight and training goal assumptions such as maintain, build, or cut.

Quick answer
The estimate uses weight-based gram-per-kilogram multipliers.
What this tells you
- •The estimate uses weight-based gram-per-kilogram multipliers.
- •Goal selection changes target protein range.
- •Protein needs vary by health status and clinical context.
How to Use
- 1Enter body weight and choose weight unit.
- 2Select your primary goal (maintain, build, cut).
- 3Calculate to view estimated daily grams and a planning range.
How It Works
Formula
Protein target = body weight (kg) x goal multiplierThis model applies simple weight-based multipliers and returns an estimated target with a practical range.
Calculation note: values are processed in the order shown above, using the current input units.

Higher training goals usually use higher protein multipliers.
Common mistakes
- Assuming one fixed protein number works for everyone
- Ignoring medical or renal considerations
- Treating estimate as a substitute for professional nutrition care
Limitations
This estimate uses generalized multipliers and does not include medical history, kidney conditions, pregnancy, or individualized nutrition protocols.
Frequently Asked Questions
No. It provides an estimate range based on goal and body weight assumptions.
Yes. The calculator converts pounds to kilograms before applying the multiplier.
Use it as a planning estimate. Medical conditions require professional guidance.
