What Is the ProteinPrice Value Score?
Direct answer: Value Score is a 0-100 number we publish on every product page. It combines four inputs: cost per gram of protein (50% weight), retailer reliability (15%), third-party label testing (20%), and customer flavor and mixability data (15%). Above 90 = excellent value. The score recomputes every time a tracked retailer changes a price.
Most "best protein" rankings online are either sponsored or based on a single dimension (usually price). That produces misleading top picks. A $20 tub that nobody finishes is not a deal. A $60 tub with perfect taste, third-party label verification, and stable retailer pricing might actually be the better value. Value Score is the formula we use to balance all of that into one comparable number.
The Four Inputs
1. Cost per gram of protein (50% weight)
The largest component. We calculate total grams of protein in the container (servings x grams per scoop) divided by the live price at the cheapest tracked retailer. A 5 lb tub with 60 servings at 25g of protein delivers 1,500g of protein. At $33, that is $0.022 per gram. At $50 the same tub is $0.033 per gram. The cheaper the protein per gram, the more points contributed to this slice.
The cheapest legitimate whey in our catalog (currently Nutricost Whey Concentrate 5lb at around $33) sets the ceiling. Products that match it earn full points on this dimension. Products that cost 2x more earn proportionally less.
2. Retailer reliability (15%)
A product is only valuable if you can actually buy it. Retailer reliability scores in our system reward products available at multiple tracked retailers and penalize ones that go out of stock often or only sell direct-from-brand with long shipping times.
Products available at Amazon, Walmart, and Costco score highest here. Direct-only brands with 5+ day shipping score lower.
3. Third-party label testing (20%)
The biggest cheating opportunity in supplements is overstating protein content on the label. Independent testing (Labdoor, NSF Certified for Sport, Informed Sport, ConsumerLab) compares lab-measured protein content against the label claim. Brands that publish results and consistently hit within 5% of label earn full points. Brands with multiple historical label discrepancies lose points heavily. Brands with no published testing earn the median score.
This is the slice that often surprises people. Some inexpensive brands (Body Fortress, certain warehouse-club private labels) have been caught with under-label protein content. They drop in Value Score even when their sticker price is low.
4. Customer flavor and mixability data (15%)
Aggregated from millions of product reviews across all 12 tracked retailers, weighted toward more recent and verified-purchase reviews. The dimensions we extract: flavor average, mixability, mouthfeel, settling at the bottom, and tub-arrived-broken complaints. Products with consistent praise across years and retailers earn full points.
This slice exists because the cheapest tub is not actually cheap if you cannot stomach it past day 3. We see this play out in our return-rate analysis: products with bottom-quartile flavor scores have above-average open-tub return rates.
How the Score Is Calculated
Each input is normalized to a 0-100 sub-score, then combined using the weights above:
- Cost-per-gram sub-score: 50% weight
- Retailer reliability sub-score: 15% weight
- Label testing sub-score: 20% weight
- Flavor / mixability sub-score: 15% weight
The final Value Score is the weighted sum, rounded to the nearest whole number. Score 100 is theoretically possible but never seen in practice because no product has the cheapest price and perfect labeling and perfect flavor scores.
How to Read the Score
- 95-100: Best in class. Genuinely hard to beat on overall value.
- 85-94: Excellent value. Most users will be very happy.
- 75-84: Solid value. Usually means one dimension is weak (often flavor or price) but the others are strong.
- 65-74: Acceptable. Often a premium product with strong flavor but weak cost-per-gram, or a budget pick with weak flavor.
- Below 65: Avoid unless you have a specific reason. Usually means at least two of the four inputs are below average.
Why Sticker Price Is Misleading
The classic example: a $19 Walmart tub of 2 lb whey looks "cheap" against a $33 Amazon tub of 5 lb whey. By sticker price, the small tub wins. By cost per gram of protein, the 5 lb tub is 35% cheaper. By Value Score, the 5 lb tub usually wins by a wide margin because it scores well on price-per-gram, while the smaller tub often loses points on flavor reviews and label-claim testing.
Live example from our catalog: Nutricost Whey Concentrate 5lb at $33 on Amazon scores 98. Optimum Nutrition Gold Standard 5lb at $55 scores 94 (better flavor and label testing, worse price-per-gram). Dymatize ISO100 5lb at $80 scores 89 (excellent flavor and label, premium price). All three are good purchases. The one that wins depends on which dimension matters most to you.

Common Questions About the Score
Does ProteinPrice get paid more for higher-scoring products?
No. The Value Score formula does not include affiliate revenue or partnership status. The scraper reads prices, the testing data comes from public third-party reports, and the flavor data comes from retailer reviews. We do earn commissions on some retailer outbound clicks; that is disclosed on our disclosure page, and it does not affect the score.
Does a higher Value Score guarantee I will like the product?
No. The score is a probability bet, not a promise. It correctly identifies products that score well across the dimensions most buyers care about. Individual taste preferences (you hate chocolate, you cannot tolerate sucralose) will always trump aggregate data.
Why does the score sometimes go down on the same product?
Because a competitor's price dropped, or a new third-party test came out, or aggregate reviews shifted. Value Score is relative. A product scoring 90 today might score 87 next month if cheaper, equally well-tested products enter the catalog.
How We Use It on Each Product Page
On every product page (e.g., browse all products), the Value Score appears prominently with a breakdown of the four sub-scores. You can see exactly why a product earned what it did. This transparency is the entire point: nothing is hidden inside the algorithm.
