It really depends on what kind of college Course you are looking for, how many years, and if you get scholarships
The first step to figure out how much it will cost you it to figure out what you want to go to college for.
College courses can go anywhere from 1 year to 13 years or even more depending on what you want to do.
The more the school and classes the more it will cost.
So your biggest bet is to talk to a guidance counselor if you haven’t graduated or to take a college tour to a college you may be interested in.
Scholarships are very helpful or financial aid. Talk to someone who has experience in the field you are looking for.
When you do all that, it will help you determine the costs.
Lastly, college is not cheap most of the time so I would of course start saving.
I hope this helps point you to finding good answers.
