All in, at the end of my wife's training, we would have been $1M ahead if she had simply worked a normal career. That's huge in your 20's and 30's when your trying to establish a house/family/etc.
As a baseline, university education in Finland costs about €10k/year on the average. Medical education is more expensive than the average, probably between €15k and €20k a year. Universities in the US are generally better funded than those in Finland, which allows them to provide more personal attention to the students. And university salaries are higher in the US than in Finland.
Overall, I would estimate something like $20k/year for the undergraduate degree and $30k to $40k/year for the medical school, for a total of $200k to $240k. And that's just for the education, not including costs of living as a student.
There are a handful of state medical schools near the $40k/r, but they are on the much cheaper end
