Estimating living costs for studying in the US: feedback welcome

Good morning, good evening, good afternoon?

I want to talk about living costs. They always seem to hold people back when applying to study abroad
Today I want to break it down step by step and talk about how to estimate living costs! (Tuition not included!)

Bottom line first: 25400USD (details depend on your personal habits). I think one person's spending roughly splits into food, clothing, housing, transportation, education and fun. Here's the breakdown for each section:

Food: 6000USD
Food costs vary from student to student, depending on eating habits and lifestyle. Monthly food spending usually runs between $300 and $600. Call it 500, so that's $6,000 a year. I'm not counting the case where you don't cook for yourself… if you can eat out for every meal, I guess you don't care much about your cost of living anyway haha

Clothing: 200USD
Clothing is usually a fairly small expense. Buying some clothes locally in the US, about $200 a year is enough.

Housing: 15000USD
Housing is the biggest expense, and it depends on where you choose to live. Here are rough estimates:

• School dorms: university dorms are usually cheaper, about $8,000 to $12,000 a year. The exact price varies by school and region. For example, a UCLA dorm costs $1,500 a month…

• Apartment rent: if you rent an apartment, rent depends on the area. Big cities like New York or San Francisco are more expensive, and smaller cities are relatively cheaper. In general, rent runs about $15,000 a year.

• Subletting or sharing: you can share a place with others to save on rent, about $12,000 a year

Transportation (no car): 1200USD
One Uber/rental car trip to Costco a month, $100 each = 1200

Entertainment: 1200USD
$100 a month for entertainment: house parties, drinking, socializing and so on

Trips: 3000USD
1000USD per trip (rough estimate) for travel within the US, three times a year

Feel free to comment and discuss whether my assumptions are reasonable enough… that's close to NT$760,000… so scary, so scary
