The real cost will be different for you
The numbers above are medians from the U.S. Bureau of Labor Statistics. The price you actually pay depends on financial aid, scholarships, family help, state residency, and which schools accept you. A "$250k" private university is often $60k to $120k after aid. A "cheap" community college can still be out of reach without a plan. Use these as a starting point, then get real quotes from the specific schools you're considering.
Location matters

Read, listen, watch
The cheapest way to find out whether you actually like a field is to read what people in it read.
- 'The Pragmatic Programmer' by Hunt & Thomas (habits of good engineers)
- 'Soul of a New Machine' by Tracy Kidder (how computers actually get built)
- Hacker News daily (news.ycombinator.com) and Lenny's Newsletter
- The Changelog and Lex Fridman podcasts
None of this is required. It's just the lowest-friction way to find out if you actually like this kind of work before you commit money or time.
