The Price-per-20g-Protein League Table (2026)

The Price-per-20g-Protein League Table (2026)

Protein products are priced to be hard to compare. Different serving sizes, different scoop weights, different grams per scoop — the label math is deliberately apples-to-oranges. This league table fixes that with one honest unit: dollars per 20 grams of protein. Same yardstick for every product, no marketing in the way.

How the unit works

Two steps, and you can run it on anything:

1. Cost per serving = price ÷ servings per container.
2. Cost per 20 g protein = (cost per serving ÷ grams of protein per serving) × 20.

Twenty grams is just a convenient, real-world "chunk" of protein — roughly what's in a scoop or a small meal. Normalizing to it lets a 28 g isolate and a 22 g isolate sit honestly in the same column. (If you want the full walkthrough, it's in how to read a nutrition panel.)

The 2026 league table (verified prices)

These are the products whose prices and panels we've verified at authoring. Everything is calculated from the published label and the current direct price.

A few honest observations before you read too much into the ranking.

The meal shake isn't really in the same race. Huel Black Edition tops the table on pure $/20 g, but it's a complete meal — that $2.65 buys 40 g protein plus a meal's worth of carbs, fats, fiber, and micronutrients. A whey isolate buys protein and almost nothing else. So Huel looks cheapest per gram of protein precisely because protein is only part of what you're paying for. If you want just protein, the isolates are the real comparison; if you want to replace a meal, Huel's number is the fair one. We keep that straight in the Huel Black Edition review.

Among the pure isolates, Transparent Labs wins on price-per-gram. Transparent Labs lands at $1.43 versus Legion at $1.82 — at the same $2.00 per serving — simply because its scoop carries 28 g to Legion's 22 g. That's not a quality verdict; both are legitimate. It's arithmetic: more grams per identical-priced scoop means fewer dollars per gram. Where they do differ on substance is testing — Transparent Labs carries an Informed Sport batch certification; Legion publishes its own lab COAs. Which matters more is your call, and we lay it out in Legion vs Transparent Labs.

Reading the table like an adult

The cheapest row isn't automatically "the answer." The table hands you the price axis; you supply the others:

• Testing tier. A drug-tested athlete may rationally pay more for the Informed Sport row and ignore a cheaper one. See third-party testing, explained.
• Format. Meal shake vs isolate vs RTD are different products doing different jobs. Compare within a format first.
• Sweetener and taste. Not on this table, and entirely personal. The cheapest tub you won't drink is infinitely expensive.

Add your own product in 30 seconds

The table's real value is the method. Holding a tub the table doesn't list? Run it:

• Price $39.99, 30 servings, 24 g/scoop → $1.33/serving → ($1.33 ÷ 24) × 20 = $1.11 per 20 g. Cheaper than everything above — now go check its testing disclosure before you celebrate.
• Price $2.50 per RTD bottle, 30 g → ($2.50 ÷ 30) × 20 = $1.67 per 20 g — mid-table, and you're paying for the bottle.

Two numbers off the label and you know exactly where anything slots in. That's the point of a league table: not to memorize our rows, but to price the shelf in front of you.

Where RTD shakes and bars land

Two formats people always ask about, and why they're not on the verified table above: we price them the same way, but their numbers move with sales and pack size, so treat these as the shape of the answer rather than fixed rows.

Ready-to-drink shakes almost always cost more per gram than powder, because you're buying the water, the bottle, and the convenience. A 30 g shake at $2.00–$2.80 apiece works out to roughly $1.33–$1.87 per 20 g — competitive with a premium isolate on paper, but you're paying isolate-level prices for a pre-mixed drink. Fine for travel; expensive as a daily base.

Protein bars are pricier still per gram, because you're also paying for the "food" experience — the coating, the texture, the shelf life. A 20 g bar at $2.00–$2.50 is $2.00–$2.50 per 20 g, near the top of any honest table. Bars earn their place as convenient snacks, not as your cheapest grams.

The pattern holds everywhere: the more a product does for you — pre-mixing, portability, flavor engineering — the more you pay per gram of the protein underneath. Powder is cheap because you do the mixing.

The value line for 2026

Verified, a premium third-party-tested isolate runs about $1.40–1.85 per 20 g, a complete-meal shake about $1.30–1.80 (remember: you're buying a meal), and a well-chosen store brand can dip under a dollar. Anchor on those and you'll spot an overpriced tub instantly.

One closing caveat, since targets come up: how many grams you need is general information here, not medical advice — confirm your target with your clinician, especially on an appetite-suppressing medication. The league table prices the protein; only you and your clinician set the number of grams.
