Frequently Asked Questions

How is price per gram of protein calculated?▼

We divide the total product price by the total grams of protein in the container (servings multiplied by protein per serving). This gives you a fair apples-to-apples comparison regardless of container size or brand.

How often are the prices updated?▼

Prices are updated daily using Amazon's Product Advertising API. However, Amazon prices can change multiple times per day, so always check the current price by clicking through to the product page.

Why is price per gram better than price per serving?▼

Serving sizes vary wildly between brands. One brand might list 20g of protein per scoop while another lists 30g. Price per gram of protein normalizes this so you can see which product actually gives you the most protein for your money.

Do you include protein bars as well as powders?▼

Yes. You can switch between protein powders and protein bars using the product type toggle at the top of the comparison table. Both are ranked by price per gram of protein.

Which countries are supported?▼

We currently support the USA (Amazon.com) and Canada (Amazon.ca) with prices in USD and CAD respectively. Use the store selector to switch between regions.

How We Compare Protein Powders

Instantly compare protein powders by price per gram of protein, serving size, and total cost. Find the cheapest, most cost-effective protein powder for your needs—whether you're looking for whey, plant-based, or vegan options. Our data is updated regularly and sourced directly from Amazon for accuracy.

We calculate price per gram of protein for every product using the formula:

Price per Gram = Total Price ÷ (Number of Servings × Protein per Serving)

This lets you see which protein powder gives you the most protein for your money, regardless of container size or marketing claims. We only use real, up-to-date prices and product info from Amazon to ensure fair comparisons. Learn more about our calculations.
