What is the cheapest plant protein powder?
Micro Ingredients Pea Protein Powder, Unflavored (5 lb) is the cheapest plant protein we track at $0.612 per 25 g of protein, before delivery. The most expensive is $8.72, a 14.2× spread for the same amount of protein.
Every figure is per 25 g of protein, computed from each product's own panel: protein per serving, times servings per container, against the price. Scoops are not the same size from one brand to the next, so a price per scoop or per tub compares nothing. Bare Performance Nutrition Vegan Protein, Thorne Plant Protein and Momentous 100% Plant Protein are priced in more than one flavor, a row for each; every other line here is priced in one.
The cheapest is not the pick. The plant protein page leads with Optimum Nutrition Gold Standard 100% Plant Protein, Rich Chocolate Fudge (1.76 lb), because a pick has to clear bars this table does not apply. Micro Ingredients Pea Protein Powder, Unflavored (5 lb) is cheaper but is not the pick: no independent verification we could locate; delivery cost is not published. A price with no published delivery rate can cost an unknown amount at checkout, so it can lead a table of shelf prices and still not be the pick.

What this table does not tell you
8 of these 23 products are certified at the exact package sold. The rest are not marked as failing anything. Which certifier database each was searched in, and what was found, is on which plant protein brands are third party tested.
It says nothing about protein quality, amino acids, digestion or taste, and it does not compare pea against a blend on anything but price. It is the price of a fixed amount of protein as each label states it, and nothing more.
Products that are out of stock today carry no price and drop out of this ranking; they are still listed on the plant protein page with their label read.
Where to buy: the plant protein shortlist
The pick is the cheapest certified product, at the exact package sold where the certifier names packages, with no adverse finding on record, a price its retailer let us read recently, and no more than a year’s supply at the label’s serving; per delivered dose where the retailer publishes a delivery rate. Where none does, it is the cheapest such product before delivery, and it says how far the order is from free delivery. It is the same pick the category page shows. Any answer shown beside it is the cheapest under a different rule and says so on its own line; answers that cost more than the pick fold under one line until you ask for them.
How these lines are chosen
Among 27 products and 27 retailer listings we track; Amazon and Walmart are not included. A month is thirty doses of the size in the heading, priced the same way as the per-dose figure beside it. “Delivery known” ranks only products whose retailer publishes a delivery rate; a cheaper product with an unpublished rate is on its own line, or in the full list below.

What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
