* Coffee consumption habits: Some students drink multiple cups a day, while others rarely buy coffee.
* Location: Coffee prices vary widely by region and even within a city. A student in a major city will likely pay more than one in a small town.
* Coffee choices: A daily latte from a specialty coffee shop is far more expensive than instant coffee at home.
* Financial resources: Students with more disposable income will spend more.
However, anecdotal evidence and various online discussions suggest that a reasonable estimate for *some* college students might range from $5 to $20 per week. Many students likely fall somewhere in this range. Some spend significantly less (perhaps $0 if they make their own coffee), and some spend considerably more if they frequently visit expensive coffee shops.
It's impossible to give a truly "average" figure without a comprehensive study specifically targeting college student coffee spending.
