Part of my strategy for eating real food on a budget (which is the EXACT same strategy I teach in Grocery Budget Bootcamp) is to make foods from scratch, when it counts.
Have you ever wondered if cooking dry beans cost less than buying canned beans?
I’ve wondered that myself, and today I’m crunching number to see which is cheaper.
Before we dig in, let’s set some basic ground rules.
1. What store do we use to compare prices?
I want to use prices that are comparable across the country. That way, this exercise applies no matter where you live in the States.
I’m choosing Walmart because it’s a national chain and the prices don’t vary too much from region to region. To account for any variation there might be, I’m using online prices, since they’re available to everyone.
2. What type of beans do we use?
By default, some beans cost less (like pinto beans) and some beans cost more (like cranberry beans). For this post, I’m comparing four of the most popular types of beans:
- black beans
- garbanzo beans (a.k.a. chickpeas)
- pinto beans
- great northern beans
3. What quality of beans do we use?
The price of beans will depend largely on the brand and whether or not you choose organic (or non-GMO or BPA-free cans, etc.). Since I’m wanting to eliminate as many variables as possible that would skew the basic comparison of dry beans versus canned beans, I’m using generic-brand beans. Not organic and nothing fancy. Just plain beans.
Every bean cooks up differently, depending on its size, but the typical yield seems to be that beans triple in volume and/or weight when cooked.
On average, the typical pound of dry beans yields anywhere from 5 to 7 cups of cooked beans. When possible, I’ve noted a better dry to cook yield for each bean and the source. If I could not find a source, I went with the average of 6 cups.
One serving of cooked beans – whether they are from a can or you make them from scratch – is ½ cup.
One 15 oz can of beans is equivalent to 1.75 cups cooked beans and there are 3.5 servings in one can, regardless of the type of bean.
Note that some cans contain exactly 15 oz, some contain 15.25 oz and some contain 15.5 oz. I don’t know for sure, but my best guess in the slight variation in the can size is due to the variation of the bean size.
Okay, the ground rules are set. Let’s see which is cheaper, dry beans or canned beans!

Cooked Garbanzo Beans

Which is cheaper: dry pinto beans or canned pinto beans?
Dry Pinto Beans
Walmart.com offers dry pinto beans in two different sizes, 32 oz (2 lbs) and 64 oz (4 lbs). We know that we can save my by buying in bulk, but let’s see how much and compare both of these sizes to canned pinto beans.
- According to Serious Eats, one pound of dry pinto beans will yield 7 cups of cooked pinto beans.
- One pound of dry pinto beans will yield 14 servings.
- If you buy a 2 lb bag, one pound of dry pinto beans costs $1.04.

Note: Walmart.com had dry pinto beans in larger sizes as well, including an 8 lb bag and a 20 lb bag. However, the price per ounce of the beans were 7¢ and 6.2¢ respectively. To put this in perspective, the 2 lb bag was 6.5¢ per ounce and the 4 lb bag was 5.8¢ per ounce. A perfect example of how buying in bulk CAN save, but that it’s always best to check prices. In this case, the 4 lb bag was the best deal. You would have paid more per ounce (and in turn, per pound) if you bought the 8 lb or 20 lb bags.

Recipes Using Great Northern Beans
Across the board, it’s cheaper to by dry beans and cook them yourself than it is to buy canned beans.
The one thing I didn’t take into consideration in this cost comparison was the actual cost of cooking. The price of electricity and gas varies, as does the cooking method (i.e. whether you cook on the stove, in a slow cooker or in an instant pot), which makes it difficult to draw a clear cut answer.
If you’re interested in including these numbers as well, this article is a good place to start with a simple, breakdown of the cost to use a slow cooker.
Many people complain that beans give them gas, and therefore don’t eat them. If that’s you, I encourage you to de-gas your beans by soaking them using this method.
As the temperatures warm up this summer, cook your beans in a slow cooker to keep the house cool.
One last thing to consider is the additives and preservatives added to canned beans.
In the four beans mentioned above, I found calcium chloride and disodium edta. Compare against the only ingredient needed to cook beans at home: water.
