Almonds vs. Walnuts vs. Pecans: Nutrients Per Dollar, Ranked

Every number in this article comes from two places, and we want you to be able to check both.

Composition came from USDA FoodData Central, using the SR Legacy records for raw, unsalted nuts wherever they exist. We pulled energy, protein, total fat, alpha-linolenic acid, vitamin E as alpha-tocopherol, magnesium, calcium, potassium and fiber per 100 grams, then converted to a one-ounce serving of 28.35 grams. If you want to follow along, the underlying records live at fdc.nal.usda.gov and each one carries the ID we used.

Two nuts needed a substitution, and we would rather name them than bury them. Pistachios and cashews are overwhelmingly sold roasted, so we used the dry-roasted, unsalted records for both rather than pretending a raw bag was on the shelf. Roasting drives off a little moisture, which nudges every per-weight figure up slightly, and the cashew we actually priced was salted while the record we used was not. Salt affects sodium, which we do not rank here, so the four ranked columns are unaffected.

Where the prices came from

Prices were captured on September 10, 2026, from live product pages at Target and Walmart — not from search results, and not from search-engine snippets. That distinction turned out to matter enormously. On the same afternoon, Target's own search page showed its raw whole almonds at $5.79 when the product page said $7.99, and Walmart's category listing showed its pecan halves at $7.14 against a live price of $4.74. That is a 51 percent overstatement on a page the retailer publishes itself. Every figure below was read off a product page for that reason, and every one is dated and store-named, because target.com and its competitors reprice constantly.

We used the most common everyday package size, generally 8 to 16 ounces, rather than club-store or bulk sizing. Two exceptions are flagged in the tables where they appear.

What we could not check

We wanted a third anchor. The brief called for cross-checking the category price level against USDA Economic Research Service data, and the ERS Fruit and Tree Nuts retail-price page returned a server error on the day of capture. There is also no Bureau of Labor Statistics average-price series covering shelled tree nuts. So the price side of this article rests on a two-retailer, same-day capture and nothing else. It is real, it is checkable, and it is a snapshot — nut prices are volatile and regional, and yours will differ.

One more disclosure, because it nearly derailed the whole piece. FoodData Central stores alpha-linolenic acid in two different fields, and the ALA-specific one is simply missing from the walnut, pecan, cashew, hazelnut, macadamia and peanut records. Asking for it alone returns no omega-3 value for six of our ten nuts, including the two this comparison turns on. Read carelessly, that absence looks exactly like a zero, and it would have ranked the highest-omega-3 nut in the field as having none. We used the general 18:3 field for those six and the ALA-specific field for the other four, and where both exist they occasionally disagree by a few hundredths of a gram.

Here is the column where the spread is so wide it stops feeling like a ranking and starts feeling like a category error.

Walnuts are 8.3 times cheaper than pecans on this axis. Against almonds they are cheaper by a factor of roughly two thousand, and that figure is arithmetically real rather than a typo — raw almonds carry 0.003 grams of ALA per 100 grams, which rounds to essentially nothing per serving. The honest way to read the almond row is not as an expensive price but as a signal that almonds are not an omega-3 purchase at all.

A single ounce of walnuts carries about 2.6 grams of ALA. For context on scale rather than as any kind of recommendation, the National Institutes of Health sets an Adequate Intake for omega-3 as ALA at 1.6 grams a day for adult men and 1.1 grams for adult women, figures you can read in the ods.od.nih.gov fact sheet. One ounce of walnuts is comfortably more than either. At 24 cents a gram, that day's worth costs somewhere around 30 to 40 cents.

Two caveats belong here, and neither is small. The first is that ALA is not the same molecule as the EPA and DHA in oily fish, and the human body converts one to the other only to a limited extent — a plant omega-3 and a marine omega-3 are related, not interchangeable. If marine omega-3 is what you are after, that is a different shopping trip, and we ran the same arithmetic on it in Canned Fish Ranked: Omega-3s Per Dollar, Mercury Per Serving.

The second is that walnut prices barely moved between the two stores we checked — $9.99 a pound at one, $9.96 at the other. That three-cent agreement is why we are comfortable calling roughly 24 cents a gram a national figure rather than one store's promotion.

Now run the same exercise on vitamin E and watch the podium invert almost perfectly.

Almonds are roughly 54 times cheaper than walnuts here, using the lower of the two almond prices we found. The nut that was nearly empty of omega-3 turns out to be the single most efficient way to buy vitamin E in the entire ten-nut field, and it is not close.

Put in those terms, 15 milligrams of vitamin E works out to roughly 87 cents from the cheaper almonds and about $1.57 from the pricier ones. The same quantity sourced from walnuts would run something like $47. Nobody buys walnuts for vitamin E, of course — but that is precisely the point. The bundle you are buying is not the bundle you might assume, and the reference values the ods.od.nih.gov fact sheet publishes make the gap easy to size.

If you find this way of thinking useful, it is the same method we applied to dairy in Cottage Cheese vs. Greek Yogurt vs. Skyr: A Full Nutritional + Price Showdown.

Almonds take the magnesium column and the protein column too, which briefly makes them look like the overall winner among the headline three.

Then you widen the field by one row and the picture changes. Peanuts — which are a legume, not a tree nut, and which we included as a benchmark rather than a contender — deliver protein at about 2.2 cents a gram. That is 3.2 times cheaper than almonds, the best tree nut on the list. They also take magnesium at roughly a third of a cent per milligram, and they place second on vitamin E behind almonds alone.

A 16-ounce jar of dry-roasted unsalted peanuts came to $2.58 at walmart.com on the day we checked, less than half the price per pound of the next cheapest item in the field. Peanuts lose exactly one column, omega-3, where they are as close to empty as almonds are.

That is worth sitting with for a moment. If your reason for buying nuts is protein or magnesium, the cheapest thing on the shelf is also the strongest performer, and it costs a third of what the premium option does. Something similar showed up when we ranked protein sources across the whole grocery store in The Best Protein Per Dollar: 25 Foods Ranked.

The fifth metric is the least glamorous and the most revealing about how fragile any per-dollar ranking really is.

Because the calorie spread across nuts is narrow — 161 per ounce at the low end, 204 at the high end, a range of about 27 percent — calories per dollar is driven almost entirely by price rather than by energy density. Which means it moves whenever prices move.

At one retailer, pecans took the column at 349 calories per dollar, ahead of walnuts at 297 and almonds at 216. At the other, almonds took it at 392, ahead of pecans at 331 and walnuts at 298. Same three nuts, same afternoon, opposite winner. Nothing about the nuts changed; the shelf did. Pecan halves at target.com were the cheapest of the three headline nuts there, and pecans are in fact the only one of the three that cost less at Target than at Walmart.

The lesson is not that one of those two answers is wrong. It is that a per-dollar ranking is only ever as stable as the prices underneath it, which is why we date and name every one.

This was the finding we did not expect, and it is probably the most useful thing in the article.

The same commodity almond cost $6.71 a pound at one national retailer and $12.18 at the other, on the same day. That is an 82 percent premium for changing nothing except which parking lot you pull into. Some of the gap is package size — the cheaper bag was larger — but not most of it.

Set that against the gap between the nuts themselves. Across the three headline nuts, the price spread ran from $8.99 to $12.18 a pound. The spread on almonds alone, between two stores, was wider than that. You can agonize over walnuts versus pecans and be swamped by a decision you made without thinking about it when you chose where to shop.

It also has real consequences downstream. Buying the cheaper almonds cuts the cost of that 15-milligram vitamin E reference from about $1.57 to about 87 cents, and it is the single change that flips the calories-per-dollar winner. Whole-natural almonds at walmart.com came in a 25-ounce bag, which sits above the everyday size band we used elsewhere, and we are flagging that rather than hiding it.

If you want to go further down this road, we looked at the retailer question directly in Which Grocery Stores Offer the Best Nutrition Per Dollar?

Here is the full field, with the headline three in place. Prices are the best verified everyday price we found at either retailer on September 10, 2026, with the store named. The bottom four are marked because they are not sold as everyday store-brand bags at either retailer — they exist only as third-party marketplace listings, which is itself part of why they price the way they do.

Dashes mark nuts whose ALA content is too close to zero for a cost-per-gram figure to mean anything. And the per-ounce composition behind all of it, straight from the FoodData Central records:

One row in that table quietly makes the case for the whole method. Brazil nuts are the most magnesium-dense nut in the field at 107 milligrams an ounce, comfortably ahead of everything else — and they finish sixth of ten on cost per milligram of magnesium, because they cost $26.94 a pound. Density and value are simply different questions, and only one of them is answered by a nutrition label.

Almonds also lead the field on calcium, at about 76 milligrams an ounce against pine nuts' 5, which puts them among the more useful non-dairy sources we ranked in Top 15 Sources of Calcium that Aren't Dairy.

Pulling all of that together, here is how we would summarize what each nut is genuinely dense in relative to what it costs.

Walnuts are the omega-3 buy, and nothing else on the shelf is close. They are mid-priced, they barely move between stores, and one ounce clears a day's reference intake of ALA several times over. They are a poor way to buy vitamin E and an unremarkable way to buy protein, and neither of those facts matters much if omega-3 is why you reached for them.

Almonds are the vitamin E buy, and also the best tree nut on this list for magnesium, protein, fiber and calcium. They are the most versatile bundle of the three by a wide margin. The one thing they are not is a source of omega-3 — the nut most people think of as the heart-healthy default is essentially empty on that particular axis.

Pecans sit in an awkward middle. They are second on omega-3, roughly eight times more expensive than walnuts for it, and they finish last of the three on protein and magnesium per dollar. What they do offer is the lowest price per pound of the headline three at one of the two stores, and the highest calorie density, which makes them a reasonable choice when flavor and energy are what you actually want.

Peanuts deserve the mention they rarely get. They are not a tree nut, and on this evidence they are the most efficient purchase in the aisle for protein, magnesium and calories, at a third of the price of the nearest tree nut.

Pistachios lose every ranked column here, but they lead the entire field on potassium at 286 milligrams an ounce and place second on fiber — a reminder that four cost columns are not the only axes that exist.

Brazil nuts, macadamias, hazelnuts and pine nuts are, at everyday US retail prices, specialty purchases. Macadamias in particular finish last or near-last on three of the five metrics while costing the second most per pound. If you buy them, buy them because you like them.

None of which means the expensive options are bad food — only that the price you pay and the nutrients you get are two separate facts that a bag rarely lets you see at once. That gap between reputation and contents shows up all over the snack aisle, and we picked through more of it in 10 Underrated Snack Foods Nutritionists Swear By.
