Is it Cheaper to make or buy Mashed Potatoes?

Mashed potatoes are the ultimate comfort food. Whether you serve them plain, top with gravy, or add some cheese and bacon to them, mashed potatoes are just a super tasty side dish!

Most people make mash potatoes from scratch, from instant potatoes, or buy premade mashed potatoes from the grocery store. This made me wonder which option was the most cost effective (aka cheaper.)

Let’s breakdown the costs of homemade mashed potatoes, using instant mashed potatoes, and buying premade mashed potatoes.

How much does homemade mashed potatoes cost?

Mashed potatoes at their basic form are really just potatoes, milk, and butter. For this cost breakdown we will use this basic form and skip any additional seasonings because those are usually based on personal preference.

Total Cost of Homemade Mashed Potatoes=$2.07 (4 servings)	51.7 cents per serving

The average cost to make homemade mashed potatoes is about $2.07 which is 51.7 cents per serving.

My local Walmart has the cheapest prices for basic items, so I used them for the pricing of each ingredient.

Instant mashed potatoes are the ultimate quick and easy side dish. You literally boil water with butter and add the potato flakes. Let’s look at how much instant mashed potatoes they cost per serving.

To save even more money, skip the small packs of instant potatoes that only make 4 servings and get the bigger size. The bigger sized boxes came out much cheaper per serving!

How much is store bought mashed potatoes?

I have to admit, I was a little surprised that instant mashed potatoes came out cheaper than homemade mash potatoes. So now let’s price out the premade mashed potatoes at the grocery store!

Buying premade mashed potatoes will average out to about $0.89 per serving. This was way higher than homemade or instant potatoes.

Skip the premade mash potatoes and purchase instant mash potatoes. They are so easy to prepare, and most can be made in the microwave too!

Are homemade mashed potatoes worth it?

Mashed Potatoes are so easy to make at home and you can add so many things like cheese, bacon, and sour cream to make then super tasty.

Unfortunately, if you are trying to save money, buying instant mashed potatoes are the most cost effective if you buy a bigger sized box.

Now if you already have potatoes on hand and are wanting to use them up, then making homemade mash potatoes are definitely worth it.
