Is Keurig coffee per cup that much more expensive than regular brewed coffee per cup?

K cup averages about 6 times (varies from 2 to 10 times) more expensive than drip brewed coffee.

The medium size cup of Kerug coffee is one cup (8 oz).

One cup of k-cup coffee costs about 35 to 70 cents.

One cup of drip coffee costs about 7 to 20 cents.

Lowest cost drip coffee - My Braun drip coffee maker makes a cup for about 7 cents. That is a 24 oz pot of coffee (4 * 6 oz) using 22g of coffee grounds per pot. My coffee grounds costs $4 per pound (454g) and tastes great. You need to shop around to get good low cost coffee grounds.
