What is the cheapest pea protein powder?
Micro Ingredients Pea Protein Powder, Unflavored (5 lb) is the cheapest pea protein we track at $0.612 per 25 g of protein, before delivery, among 11 packages from 3 brands whose panel names pea and nothing else. 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. A serving is not the same size from one bag to the next, and 5 of these print tablespoons rather than a scoop, so a price per serving or per bag compares nothing. 12 more packages name pea beside other sources on the panel; they are on the plant protein ranking and not here.
What this table does not tell you
Nothing here is certified at the exact package sold. Which certifier databases each was searched in, and what was found, is on which plant protein brands are third party tested. Absence from a database is not a failed test.
It says nothing about protein quality, amino acids, digestion or taste. 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; they are still 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 “Delivery known” ranks only products whose retailer publishes a delivery rate; a cheaper product with an unpublished rate is on its own line, or in the full list below.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.
