Coffee at my new work is undrinkable garbage so I have to make my own now so this has become an expense. Tried to do some calcs for cost of making coffee with different methods for my own benefit, but figured some might be interested, and have input/corrections. It's not exact as I took input from different sources. I did not weigh it myself. I especially need to double-check how much goes into my coffee maker (I use 1 scoop per cup of water. Five scoops yields ~two mugs). I'm surprised there are such large differences, almost 3x as much.
I buy
fancy coffee (on sale), so $6 per 12 oz bag. A mug is 1.5 cups/354 ml.
| Beans | Brewed | $/mug |
Aeropress | 28 g | 354 ml | $0.51* |
French press | 20 g | 355 ml | $0.35 |
Cold brew | 290 g | 2100 ml | $0.86 |
Coffee maker | 17.5 g | 354 ml | $0.31 |
Nescafe Instant | 2.3 g (1 tsp) | 354 ml | $0.06 |
Percolator | 14 g (~2 tbsp) | 354 ml | $0.25 |
Pour-over | 30 | 354 ml | $0.58* |

Notes:
Oxo cold brew device. Letting the cold brew sit longer will increase strength, yielding more finished coffee. This is using a 2:1 ratio.
Nescafe instant is $0.76/oz on amazon
Percolator amount is just rough estimate from online instructions. Need to measure.
Pour-over recipe just from 1st google hit, "blue bottle coffee". No experience with this method. $11 for 200 filters
edit: found aeropres recipes calling for less coffee, between 1 "scoop" and 18 grams. That would bring it about even with drip coffee maker.
edit: looked up/recalculated french press recipe
