Protein Powder Scoop Calculator

About this calculator

Protein powder scoop sizing is a simple division: number of scoops = target protein (grams) divided by protein per scoop (grams). Most whey and casein powders deliver roughly 20-25g of protein per standard scoop, but the exact figure varies by brand and formula, so it’s worth checking the label rather than assuming a round number.

Athletes and gym-goers use this to hit a specific per-shake protein target — say, 30g after a workout — without eyeballing scoops, especially when stacking protein powder with other sources across the day to reach a total daily intake goal (commonly cited around 1.6-2.2g per kg of body weight for people training regularly). It also matters for cost and calorie tracking, since scooping ’a bit extra’ adds up in both grams of protein and total macros over weeks of use.

This calculator takes your target protein amount and the protein content per scoop from your product’s label and tells you exactly how many scoops to use.
