Having just graduated from medical school 2 years ago...

Applying for med school is your first cost; figure roughly $50 per school for the primary application, another $100ish for a secondary if she gets it, then whatever travel/housing if she gets an interview. Applications are done through AACOMAS, AMCAS, or if you're looking at Texas, they have their own "we're special" application service. Depending how good/bad her grades are, she may be applying more than on year. If she hasn't taken her MCAT yet, there's another cost.

Most US public in-state tuitions range from 15K-30K annually. Figure another 2-3K for books and supplies, plus whatever living costs she's going to have (close to 1500/mo in a city, 500 in a rural area). Private schools go from about 30-60K annually; I think Tufts in Boston has the highest tuition of any private school, at about $66K/year. So, you're figuring, ballpark somewhere between $40-60K/year total for a decent school.

No idea on UK.

Yes, out of country schools are cheaper. I can't comment on quality of education, but several Caribbean schools send their students back to the US for their third and fourth years, so if she's looking at those options, it's something to consider (as well as moving costs!).

However, there's also a lot more hoops to go through when you graduate from a foreign medical school (FMS) if you want to practice in the US. She'll need to do her homework on that - even if she goes to a first world country like Canada or the UK.

Boards are also pricey. You can look up prices, but don't be suprised to pay about $1K for step 1, another $1-2K for step 2 (it includes a real-life portion), both of which are required for graduation.

Then of course, she'll have to start paying loans off once she's an intern, making around $30k/year for her residency period. After, of course, applying through ERAS and their chunk of change...

Seeing a trend yet?
