First, there's the cost of the machine. Recently, marketing professor Eric Anderson at Northwestern University's Kellogg School of Management noted that in 2002, the average coffee maker cost $35. Today it's still easy to find a basic coffee maker for that price, or even $20 or $25. By 2013, however, the average coffee maker purchase price hit around $90, partly due to the spread of pricey single-pod brewers from Keurig (the K in K-Cups), Nespresso, and others.

As awesome as that sounds, the convenience of the Keurig comes with a price. Keurig coffeemakers cost more money to purchase upfront and to operate over their life. Initially, a Keurig 2.0 K350 brewer retails for $149.99 while a typical brew coffeemaker can be purchased for less than twenty dollars. Making matters worse, Keurig machines are also more expensive when it comes to brewing coffee.

To compare costs, I went to a local grocery store and priced out coffee and coffee filters: 1  $7.99 for a box of 12 Folgers K-Cups ($0.66 per cup) 2  $7.99 for a 28.8 ounce tub of Folgers coffee ($0.04 per 8 ounce cup) 3  $3.37 for 200 coffee filters (less than $0.02 per filter)

A reusable coffee filter is available for some Keurig models so that you can use your own ground coffee. This will make the price per cup almost equal between the two coffee making systems, but still, you have to pay a much higher price for the initial cost of the Keurig.

On average, the Keurig branded coffee makers will cost anywhere from $79 to as much as $250. This will depend on the features the maker has and the model. One with a grinder can cost anywhere from $80 to $150. This brewing system will use the K-cups and grind coffee grounds.

Probably the largest cost of the Keurig coffee maker are the Keurig single-serve coffee cups. These can cost $0.50 to $1 per K-cup, depending on the brand and flavors. Most of these will have to be purchased in boxes of 10 or more. The Keurig brand has hundreds of flavors.

Prices will vary between brand and retailer, but they typically cost between 50 and 80 cents each. This is high compared to making a pot of coffee. Assuming that tap water is used and using the above prices, making a 12-cup pot of coffee will cost about 50 cents, which is less than a 66 cent cup of Keurig coffee.
