25 Foods Ranked by Calcium Per Dollar, With Calories Per 300 mg as the Guardrail

The price sources, the nutrient records and the guardrail

Every row starts with a USDA nutrient record for calcium and calories per 100 grams, taken from USDA FoodData Central. For the fortified foods, where the amount of calcium depends on the manufacturer, we used the leading brand's current label record in FoodData Central's branded database rather than an older generic value. Each food's price was then converted to the same 100-gram basis, so every comparison is apples to apples.

Prices come from two federal sources. Five foods have a live national shelf price: whole milk, lower-fat milk, yogurt, natural cheddar and dried beans are all tracked monthly in the Bureau of Labor Statistics average price series, and the August 2026 figure is used for each, including the BLS gallon price for low-fat, reduced-fat and skim milk of $3.715.

The other 20 foods have no current national price series, so they are priced from the USDA Economic Research Service's Purchase to Plate national average prices, which record the price per 100 edible grams of thousands of foods from 2017/2018 retail scanner data. Only rows linked directly to scanner data were used. Each 2017/2018 price was then carried forward to 2026 dollars using the Consumer Price Index for that food's own aisle, so canned fish rises with canned fish prices and fresh greens with fresh vegetable prices.

Three numbers come out of that math. Milligrams of calcium per dollar is the ranking metric. Cost per 300 mg translates it into a single, familiar dose. Calories per 300 mg is the guardrail, and the cutoff of 200 calories is 10% of the 2,000-calorie reference diet used on every Nutrition Facts label under the federal labeling rule in 21 CFR 101.9, which also sets the Daily Value for calcium at 1,300 mg.

A useful property of both ratios: they do not change when a food is cooked. Boiling kale or soaking beans changes the weight, but calcium and calories stay together, so an as-purchased record gives the same answer as a cooked one.

This ranking measures calcium on the label, not what happens after you eat it, and it makes no claim about bone outcomes. If that evidence is what you are after, our look at why calcium and vitamin D barely moved fracture risk across 69 trials covers it.

The full ranking at a glance

The vegetable that trips the calorie guardrail

Broccoli shows up on nearly every calcium list, which makes its last-place finish here the first surprise. Raw broccoli carries 47 mg of calcium per 100 grams, a modest amount, and at a modeled 2026 price of about $4.06 a pound, a dollar buys just 52 mg.

The calorie side is where it really stumbles. Broccoli is a low-calorie food, but because its calcium is so dilute, you would need about 638 grams, roughly seven cups chopped, to reach 300 mg. That brings 217 calories with it, just over the 200-calorie guardrail. It is the only green vegetable on this list to cross the line.

None of this makes broccoli a poor food. It simply means that if calcium per dollar is the goal, broccoli is carrying other nutrients to the table rather than this one. Broccoli is also priced from the Purchase to Plate data because the Bureau of Labor Statistics stopped publishing a national broccoli price after March 2020.

Calcium per dollar: 52 mg. Cost per 300 mg: $5.71. Calories per 300 mg: 217, over the guardrail.

A sesame reputation that depends on the seed coat

Sesame has a reputation as a calcium-rich food, and tahini inherits it. The label tells a more complicated story. USDA's record for tahini made from an unspecified type of kernel reads 141 mg per 100 grams, while tahini ground from whole, roasted kernels reads 426 mg. Much of the calcium sits in the seed coat, and many supermarket tahinis are made from hulled seeds.

Ranked on the more typical 141 mg, tahini lands at 64 mg of calcium per dollar, with 300 mg costing $4.66. The calorie cost is the steepest on the list: 1,260 calories, because tahini is mostly fat. Even at the higher whole-seed value, it would still cost about 419 calories per 300 mg.

Tahini brings a lot to a dressing or a bowl of hummus. As a calcium buy, it is one of the most expensive options here in both dollars and calories.

Calcium per dollar: 64 mg. Cost per 300 mg: $4.66. Calories per 300 mg: 1,260, over the guardrail.

Low in calories, high in price, and a special case on absorption

Spinach is light enough to pass the guardrail easily at 70 calories per 300 mg. The problem is price. Raw spinach delivers 99 mg of calcium per 100 grams and costs about $5.42 a pound in 2026 dollars, so a dollar buys only 83 mg. Reaching 300 mg takes about 303 grams, around ten loosely packed cups of raw leaves.

There is a second wrinkle that no price table can capture. According to the NIH Office of Dietary Supplements, calcium absorption from spinach is only about 5%, compared with about 27% for milk, because spinach's oxalic acid binds much of its calcium.

This ranking does not model absorption, and spinach is ranked on the calcium it contains. Our companion ranking of non-dairy calcium sources by how much your body actually absorbs picks up where this one stops.

Calcium per dollar: 83 mg. Cost per 300 mg: $3.62. Calories per 300 mg: 70.

An inexpensive staple that just isn't a calcium food

Chickpeas are a budget hero for protein and fiber, and at about $2.21 a pound for the drained beans in 2026 dollars, they are one of the cheaper foods in this ranking by weight. Calcium is not their strength, though. Canned, drained chickpeas carry 45 mg per 100 grams.

That puts calcium per dollar at 92 mg and the calorie cost at 927 calories per 300 mg, the second-highest on the list. You would need about 667 grams of drained chickpeas, the contents of two and a half to three standard cans, to reach 300 mg.

It is a useful reminder that a food can be good value overall and poor value for one particular nutrient.

Calcium per dollar: 92 mg. Cost per 300 mg: $3.25. Calories per 300 mg: 927, over the guardrail.

The dairy food that loses most of its calcium on the way to the tub

Plenty of people assume every dairy food is a calcium powerhouse. Cottage cheese is the exception. Low-fat cottage cheese carries just 61 mg of calcium per 100 grams, a fraction of milk or yogurt, because much of the calcium leaves with the whey when the curds are formed.

At a modeled price of about $2.51 a pound, a dollar buys 110 mg, and 300 mg costs $2.72. It takes nearly 500 grams, a little over two cups, to get there, and that portion carries 354 calories.

Cottage cheese has its own strengths, protein chief among them. As a calcium source, it lands close to almonds, one of the priciest foods on this list.

Calcium per dollar: 110 mg. Cost per 300 mg: $2.72. Calories per 300 mg: 354, over the guardrail.

Calcium-rich by weight, expensive by the dollar and by the calorie

Ounce for ounce, almonds are one of the more calcium-dense foods here, at 269 mg per 100 grams. Price and calories are what hold them back. At a modeled 2026 price of about $10.98 a pound, a dollar buys 111 mg of calcium.

Getting to 300 mg takes about 112 grams, or roughly 90 almonds, and that handful carries 646 calories. That is the kind of trade that shows up in the guardrail column immediately.

If you are curious how almonds stack up against other nuts on price and nutrients more broadly, our almonds, walnuts and pecans cost comparison runs the full numbers.

Calcium per dollar: 111 mg. Cost per 300 mg: $2.70. Calories per 300 mg: 646, over the guardrail.

The calcium is in the bones, so the can you pick matters

Canned salmon earns its calcium reputation almost entirely from its soft, edible bones. USDA's record for canned pink salmon, drained, with bones, reads 283 mg per 100 grams. The same fish without skin and bones reads just 60 mg. Skinless, boneless cans lose almost 80% of the calcium.

With bones in, a dollar buys 134 mg, and 300 mg costs $2.24. The calorie cost is a reasonable 146 calories, comfortably under the guardrail, for about 106 grams of fish, a little less than a four-ounce serving.

Canned salmon is one of the pricier foods on this list per pound. It comes with protein and omega-3s, so it is often bought for more than its calcium.

Calcium per dollar: 134 mg. Cost per 300 mg: $2.24. Calories per 300 mg: 146.

Among the lightest calcium on the list, at a middling price

Bok choy is one of the lightest foods in this ranking. At 105 mg of calcium and only 13 calories per 100 grams, 300 mg costs just 37 calories. It is also a relatively inexpensive vegetable, modeled at about $2.34 a pound in 2026 dollars.

The catch is volume. You would need about 286 grams, around four cups shredded, to reach 300 mg, and that pulls calcium per dollar down to 204 mg. It is a better buy than spinach or broccoli, but well behind collards and kale.

One note on the price: the national price record groups bok choy with other Chinese cabbages, including napa, so the modeled price is a blend.

Calcium per dollar: 204 mg. Cost per 300 mg: $1.47. Calories per 300 mg: 37.

Dense, portable and priced like a treat

Sardines are one of the most calcium-dense foods in the grocery store. Atlantic sardines canned in oil, drained with their bones, carry 382 mg of calcium per 100 grams, so about 79 grams, most of a standard tin, delivers 300 mg.

Price is what keeps them in the middle of the pack. At a modeled cost of about $7.69 a pound of drained fish, a dollar buys 225 mg, and 300 mg costs $1.33. The calorie cost of 163 calories sits under the guardrail, helped by how little fish it takes.

Compared with canned salmon, sardines deliver about 70% more calcium per dollar. Both depend on the bones, so boneless versions tell a very different story.

Calcium per dollar: 225 mg. Cost per 300 mg: $1.33. Calories per 300 mg: 163.

Generic molasses ranks here; blackstrap would climb much higher

Molasses is on this list because blackstrap molasses is often mentioned as a plant source of calcium. The national price data, however, only tracks molasses in general, and USDA's generic record reads 205 mg of calcium per 100 grams. On that basis, a dollar buys 233 mg, and 300 mg costs 424 calories, well over the guardrail.

Blackstrap is a different product. Labels such as Plantation Organic Blackstrap Molasses read 690 mg per 100 grams, and six blackstrap labels in USDA's branded database span 600 to 910 mg. Without a national blackstrap price, it cannot be ranked fairly here.

Either way, the calorie guardrail is the limiting factor. Even blackstrap carries about 124 calories per 300 mg of calcium, and it is a sweetener most people use by the spoonful.

Calcium per dollar: 233 mg. Cost per 300 mg: $1.29. Calories per 300 mg: 424, over the guardrail.

Solid value, and a reason regular yogurt beats Greek on calcium

Plain low-fat yogurt carries 183 mg of calcium per 100 grams. Using the BLS national yogurt price of $1.584 per 8 ounces in August 2026, a dollar buys 262 mg, and 300 mg costs $1.15. At 103 calories per 300 mg, it is comfortably under the guardrail.

That price series covers yogurt of all types, not plain alone, so it is a reasonable national average rather than the price of one tub.

Greek yogurt is not ranked because it has no directly measured national price, but the nutrient records point to something worth knowing. USDA's plain nonfat Greek yogurt carries 110 mg of calcium per 100 grams, roughly 40% less than regular plain low-fat yogurt. Straining removes whey, and calcium leaves with it. Thicker and higher in protein, Greek yogurt is the lower-calcium choice.

Calcium per dollar: 262 mg. Cost per 300 mg: $1.15. Calories per 300 mg: 103.

An inexpensive green with calcium that behaves like milk's

Kale delivers 254 mg of calcium per 100 grams raw with only 35 calories, so 300 mg costs just 41 calories. At a modeled 2026 price of about $3.73 a pound, a dollar buys 309 mg.

About 118 grams of raw kale reaches 300 mg. That is a generous bunch, closer to five or six cups chopped raw, though it cooks down to a much smaller pile. Because the ratio holds whether kale is raw or cooked, the math does not change in the pan.

Kale also sits on the other side of spinach's absorption problem. The NIH notes that calcium from kale, broccoli and cabbage is absorbed at rates similar to milk.

Calcium per dollar: 309 mg. Cost per 300 mg: $0.97. Calories per 300 mg: 41.

A fortified cereal that clears the price bar, not the calorie bar

Cheerios is the fortified cereal in this lineup, and its current label record in USDA's branded food database reads 333 mg of calcium and 367 calories per 100 grams. At a modeled price of about $4.36 a pound, a dollar buys 346 mg.

The guardrail is where cereal falls down. Reaching 300 mg takes about 90 grams, more than two standard servings, and 331 calories before any milk goes in. Of course, most people add milk, and the milk is the better calcium buy of the two.

Interestingly, Total, the cereal many readers remember as the calcium-fortified choice, reads only 100 mg per 100 grams in its 2026 record. It is not ranked here because it has no national price. For a wider look at cereal economics, our ranking of 20 "healthy" cereals by fiber per dollar uses the same price data.

Calcium per dollar: 346 mg. Cost per 300 mg: $0.87. Calories per 300 mg: 331, over the guardrail.

The best-value leafy green on the list

Collard greens are the leafy green winner. Raw collards carry 232 mg of calcium per 100 grams with only 32 calories, and at a modeled price of about $2.91 a pound, they are cheaper than kale. A dollar buys 361 mg of calcium, and 300 mg costs 83 cents and 41 calories.

About 129 grams of raw collards, three or four cups chopped, reaches 300 mg. Like kale, collards cook down dramatically, so a cooked portion looks much smaller on the plate.

For anyone looking for calcium outside the dairy case, collards offer one of the strongest combinations of price and calories in the ranking.

Calcium per dollar: 361 mg. Cost per 300 mg: $0.83. Calories per 300 mg: 41.

Calcium-dense by the spoonful, but over the calorie line

Chia seeds are one of the most calcium-dense foods here, with 631 mg per 100 grams. About 48 grams, roughly four to five tablespoons, delivers 300 mg. At a modeled price of about $7.12 a pound, a dollar buys 402 mg.

The guardrail catches them. That portion carries 231 calories, a little over the 200-calorie line, because chia is rich in fat. That is a smaller miss than almonds or tahini, and many people use chia a spoonful at a time, which keeps both the calcium and the calories modest.

Calcium per dollar: 402 mg. Cost per 300 mg: $0.75. Calories per 300 mg: 231, over the guardrail.

Cheap calcium, but it arrives with a full meal's calories

Dried beans are one of the few foods here with a live national price. The BLS price for dried beans was $1.630 a pound in August 2026, and USDA's record for raw navy beans reads 147 mg of calcium per 100 grams. That combination buys 409 mg of calcium per dollar.

The trade-off is calories. Beans are an energy-dense staple, and reaching 300 mg takes about 204 grams of dry beans, roughly a cup before cooking, which becomes two to three cups cooked. That portion carries 688 calories.

Navy beans were chosen as the most common white bean. The price series covers dried beans of any type, so this is an average bean price paired with a white bean's calcium.

Calcium per dollar: 409 mg. Cost per 300 mg: $0.73. Calories per 300 mg: 688, over the guardrail.

One of the best buys on the list, if the label says calcium sulfate

Tofu made with calcium sulfate as the coagulant is one of the standout values. USDA's record for regular tofu set with calcium sulfate reads 350 mg per 100 grams and only 76 calories. At a modeled price of about $3.64 a pound, a dollar buys 436 mg, and 300 mg costs 65 calories, one of the lowest calorie costs here.

The label matters enormously. USDA's firm tofu set with calcium sulfate reads 683 mg per 100 grams, while Nasoya Organic Firm tofu's label record reads 118 mg. That is roughly a sixfold spread within one shelf category. This ranking uses the middle, more conservative calcium sulfate value.

Calcium per dollar: 436 mg. Cost per 300 mg: $0.69. Calories per 300 mg: 65.

A live shelf price and a small portion

Natural cheddar has a live national price, and the BLS cheddar series put it at $5.983 a pound in August 2026. With 710 mg of calcium per 100 grams, a dollar buys 538 mg, and 300 mg costs 56 cents.

Only about 42 grams of cheddar, around an ounce and a half, is needed to reach 300 mg. That portion carries 170 calories, under the guardrail but the highest calorie cost of any dairy food that passes it.

If you are comparing cheeses on other measures too, our ranking of 20 cheeses by protein per calorie adds sodium to the picture.

Calcium per dollar: 538 mg. Cost per 300 mg: $0.56. Calories per 300 mg: 170.

Strong numbers, with an estimated price

Calcium-fortified orange juice is labeled at 146 mg of calcium and 46 calories per 100 grams across the three national brands, including Tropicana's calcium and vitamin D line. About 205 grams, a little under a cup, reaches 300 mg for 95 calories.

The price comes with an asterisk. The national price data has no separately measured price for calcium-added juice; its entry simply copies the price of regular carton orange juice. So this row uses the regular carton price, about $1.11 a pound in 2026 dollars, and should be read as an estimate. On that basis, a dollar buys 596 mg of calcium.

If fortified juice carries a premium where you shop, it would slip a place or two, but it would likely stay in the top half.

Calcium per dollar: 596 mg (estimate). Cost per 300 mg: $0.50 (estimate). Calories per 300 mg: 95.

The best-value cheese, and one of the best-value foods overall

Part-skim mozzarella is the quiet overachiever of this ranking. It carries 782 mg of calcium per 100 grams, more than cheddar, and only 254 calories. About 38 grams, a little over an ounce or roughly one string cheese and a bit, delivers 300 mg for 97 calories.

At a modeled price of about $5.45 a pound, a dollar buys 651 mg of calcium, and 300 mg costs 46 cents. That makes it the cheapest calcium on the list outside the milk and plant-milk aisle.

Mozzarella also shows up well on protein, which our best protein per dollar ranking explores in more detail.

Calcium per dollar: 651 mg. Cost per 300 mg: $0.46. Calories per 300 mg: 97.

Fortified, affordable and far above the old generic value

Soy milk's calcium comes from fortification, so the brand matters. Silk Original Soymilk's label record reads 196 mg of calcium and 46 calories per 100 milliliters. That is about 60% more calcium than USDA's older generic record for fortified soy milk, which reads 123 mg.

At a modeled price of about $1.02 a pound, a dollar buys 874 mg of calcium. About 153 grams, roughly two-thirds of a cup, reaches 300 mg for 70 calories.

Because fortification levels change and differ between brands, the Nutrition Facts panel on the carton is the reliable number for any specific soy milk.

Calcium per dollar: 874 mg. Cost per 300 mg: $0.34. Calories per 300 mg: 70.

The lightest calcium on the list by a wide margin

Unsweetened almond milk is the calorie champion. Silk Almondmilk Unsweetened's label record reads 196 mg of calcium and just 12 calories per 100 milliliters, so 300 mg costs only 18 calories. The next-lightest food on the list, bok choy, is twice that.

At a modeled price of about 94 cents a pound, a dollar buys 947 mg of calcium, and 300 mg costs 32 cents. That puts it just behind the three dairy milks.

Almost all of that calcium is added during manufacturing. Unfortified or sweetened versions read very differently, so the unsweetened, fortified carton is the one these numbers describe.

Calcium per dollar: 947 mg. Cost per 300 mg: $0.32. Calories per 300 mg: 18.

Still a top-three buy, with the highest calorie cost of the milks

Whole milk carries 113 mg of calcium per 100 grams, a little less than lower-fat milks. The BLS whole milk price was $4.229 a gallon in August 2026, which works out to about 49 cents a pound.

That buys 1,043 mg of calcium per dollar, with 300 mg costing 29 cents. It takes about 265 grams, just over a cup, to get there, and that portion carries 162 calories, under the guardrail but the highest of the three dairy milks.

Whole milk still delivers more calcium per dollar than any non-milk food in this ranking.

Calcium per dollar: 1,043 mg. Cost per 300 mg: $0.29. Calories per 300 mg: 162.

A near tie for first place

Reduced-fat 2% milk carries 120 mg of calcium per 100 grams and 50 calories. The national price series groups 2%, 1% and skim milk into one gallon price, $3.715 in August 2026, so 2% and skim share the same shelf price in this ranking.

A dollar of 2% milk buys 1,261 mg of calcium, about 97% of the 1,300 mg Daily Value. Reaching 300 mg takes about 250 grams, essentially a cup, for 24 cents and 125 calories.

Calcium per dollar: 1,261 mg. Cost per 300 mg: $0.24. Calories per 300 mg: 125.

The cheapest calcium in the grocery store, and one of the lightest

Skim milk takes the top spot. At 122 mg of calcium per 100 grams and a shelf price of $3.715 a gallon, a dollar buys 1,287 mg of calcium, about 99% of the Daily Value. One cup, about 245 grams, delivers roughly 300 mg for about 23 cents.

It clears the guardrail easily too, at 84 calories per 300 mg. Only almond milk, the leafy greens, tofu and soy milk are lighter, and none of them is cheaper per milligram.

Compared with the bottom of this list, the spread is striking. A dollar of skim milk buys about 25 times as much calcium as a dollar of broccoli.

Calcium per dollar: 1,287 mg. Cost per 300 mg: $0.23. Calories per 300 mg: 84.

What the numbers suggest, and where they stop

Three patterns stand out. First, the milk aisle dominates on price. The three dairy milks and the two fortified plant milks hold the top five spots, and every one of them clears the calorie guardrail.

Second, the guardrail reshuffles the picture for nuts, seeds and legumes. Chia, navy beans and almonds all look reasonable on price, but each costs between 231 and 688 calories per 300 mg. That is where the calorie column earns its place in the table.

Third, labels matter more than categories. Tofu ranges sixfold depending on its coagulant, canned salmon loses most of its calcium without its bones, and fortified plant milks now read well above the generic values most calcium charts still use.

A few limits are worth keeping in mind. Twenty of the 25 prices are 2017/2018 national averages carried forward with the Consumer Price Index, so they describe relative value rather than the exact price on your local shelf. Fortification varies by brand. And this ranking counts calcium on the label, not calcium absorbed.

How much calcium any one person needs varies by age and sex, and our guide to calcium and vitamin D needs at each decade covers those figures in depth.
