How this calculator works
Set daily protein grams from body weight and training goal. Estimates only—not a diagnosis or prescription. Protein (g) = bodyweight kg × g/kg target (often 1.6–2.2). Example: 180 lb (82 kg) at 2.0 g/kg → ~164 g protein/day.
Protein (g) = bodyweight kg × g/kg target (often 1.6–2.2).
Example: 180 lb (82 kg) at 2.0 g/kg → ~164 g protein/day.
When to use this Protein Intake
Common use cases
- Set daily protein grams from body weight and training goal.
- Sanity-check with this case: 180 lb (82 kg) at 2.0 g/kg → ~164 g protein/day.
- The relationship is: Protein (g) = bodyweight kg × g/kg target (often 1.6–2.2).
Localized examples
- Health, Fitness & Wellness: the example on this page uses the same formula as the widget.
What you get
- Fields: Weight (lbs), Protein (g/kg)
- Protein (g) = bodyweight kg × g/kg target (often 1.6–2.2).
- Example on the page: 180 lb (82 kg) at 2.0 g/kg → ~164 g protein/day.
How to Calculate Protein Intake Step-by-Step
- 1Enter Weight (lbs), Protein (g/kg). Use the values you have, not a catalog average, unless that is all you know.
- 2Protein (g) = bodyweight kg × g/kg target (often 1.6–2.2).
- 3Worked case: 180 lb (82 kg) at 2.0 g/kg → ~164 g protein/day.
- 4If this number would change a drug, a diet, or a return-to-play call, take it to a clinician. The page never examined you.
Governing formula
Protein (g) = bodyweight kg × g/kg target (often 1.6–2.2).
180 lb (82 kg) at 2.0 g/kg → ~164 g protein/day.
Example: set Weight (lbs) = 180, Protein (g/kg) = 2, then read the result.

Practical guide
Using the Protein Intake Calculator well
Who this is for
Lifters and dieters setting a daily protein target from body weight and goal.
Worked example
At 75 kg with a hypertrophy focus, targets often land near 120–165 g/day depending on the guideline you follow—then distribute across meals you can actually eat.
Hit the target with food you like
The best protein number is one you can repeat. Use the calculator for a range, then build meals you will not abandon in week two.
Common pitfalls
- Setting a target you cannot hit with your food preferences
- Ignoring total calories while only tracking protein

Very usable on mobile. Would love a save/export option later, but the math feels solid.
