I'm hooked on coffee flavored milk at the moment. Anyhow it seems so much more expensive than plain old milk. Considering I was bored I decided to work out how much it costs to make coffee milk yourself by the use of coffee milk additives in plain milk.
I did not shop around for the best prices
Metric System used for measurements
No naming of the brands concerned
A 600ml bottle of flavoring costs $6.75 and the serving suggestion of 2 teaspoons (10ml) meaning you get 60 doses of flavoring from it. before you run out (or have a spill)
2 Liters of milk costs $2 and you get 8 250ml serves.
8 goes into 60 7.5 times, meaning if you were to want to make one big batch of coffee flavored milk using the whole bottle of flavoring in one go you would need 15L of milk for it to mix in.
If you were to do this you would need to buy 8 2 liter bottles of milk and have 1 liter left over.
COST OF THE PRODUCT AS MADE
Upfront cost of coffee flavor + 2 liter milk was $8.75 (8 serves), or 1.09375 per serve...but remember you'll still have left over coffee flavor; enough in fact for another 13 Liters of milk.
The pre-made coffee milk cost $5.28 for 2 liters (8 serves), or 66c per serve...once it's gone, it's all gone.
The total cost for 60 home mixed servings + 1 spare liter of milk $22.75
The total cost for 60 pre-made coffee servings $39.60
