Computer science major: Degrees, careers, and salaries
What a computer science degree involves, how much math it takes, the B.A. vs. B.S. choice, US salaries, and what the leading European programs cost.
A software developer in the US earns a median of about $130,000 a year, according to the Bureau of Labor Statistics. That figure explains why computer science draws so many applicants. It does not explain what the degree asks of a student: years of abstract logic, a lot of math, and patience with code that fails on one missing semicolon.
This guide covers who tends to enjoy CS, how much math it takes, the B.A. vs. B.S. choice, the careers and salaries, and what the leading programs cost in Europe.
Will you like computer science?
The biggest challenge comes first: abstract logic. CS is more than learning to code. It is a way of thinking: taking a large, messy problem and breaking it into small, exact steps.
You will probably enjoy CS if you like puzzles, pay attention to detail, and keep going when something breaks. One wrong semicolon will break your code. The reward is building something and watching it work.
CS is a poor fit for students who get frustrated by small setbacks, dislike abstract thinking, or are not prepared to be meticulous and patient.
The people side. The stereotype is a solo coder in a dark room. Modern software is built in teams. Engineers work in methods like Agile and Scrum, review each other's code, and explain complex ideas to managers. Communication and teamwork matter as much as coding.
The math. CS is a branch of applied mathematics. Most programs require Calculus I and II. Two other courses matter more: Discrete Mathematics, the logic behind computing, and Linear Algebra, which underpins AI and graphics.
The first choice: B.A. or B.S.
In the US, the degree type tells employers what kind of training a graduate has. European universities award a BSc in almost every case, so this choice applies mainly to US applications.
| Bachelor of Arts (B.A.) | Bachelor of Science (B.S.) |
|---|---|
| The "Connector" Degree | The "Technical" Degree |
| Provides a solid CS foundation. | A deep, math-heavy, theoretical program. |
| Fewer advanced math & theory requirements. | More required courses in advanced algorithms. |
| Gives you flexibility to double-major. | Focuses on core theory & systems programming. |
| Ideal for UX/UI, product management, or combining CS with business, design, or art. | Ideal for software engineers, AI/ML specialists, or pursuing a master's or Ph.D. |
Equedu note: A B.A. is not a lighter CS degree. Many people in product management and front-end development hold one. Check each college's course catalog to see which path fits the career you want.
How CS compares with other tech majors
- Computer Science vs. Data Science. CS builds the tools: algorithms, apps, and databases. Data science uses those tools, plus statistics, to analyze data.
- Computer Science vs. Computer Engineering. Computer engineering covers hardware and software: the chips and circuits, and the code that runs on them. CS focuses almost entirely on software and theory.
- Computer Science vs. Software Engineering. At most colleges, software engineering is a specialization within CS. CS is the theory of why computation works. Software engineering is the practice of building large, reliable applications in a team.
What a CS degree leads to
Most CS careers fall into four groups.
- Software development. The most common path. Roles include software engineer, back-end developer (servers and databases), front-end developer (the part users see), and mobile app developer.
- Data and AI. The fastest-growing group and often the best paid. Roles include data scientist, machine learning engineer, and data engineer, who builds the pipelines that move data.
- Systems and infrastructure. The people who keep everything running: cybersecurity analysts, cloud engineers working on platforms like Amazon Web Services, and network architects.
- Tech and people. Roles that connect the technical team and the user: product managers, who decide what to build next, and UX/UI designers, who decide how it looks and works.
Salary and job outlook
CS graduates are hired across industries, not only by tech companies. Median US pay for common CS roles, from the U.S. Bureau of Labor Statistics:
- Software developers: about $130,160
- Data scientists: about $120,230
- Cybersecurity analysts: about $120,360
- Product managers (usually requires experience): about $130,000 to $170,000 or more
Pay varies widely by location, company size, and experience. Silicon Valley pays more than the Midwest.
How a European CS degree compares with an American one
For Equedu's international students, many of the strongest CS programs are in continental Europe, at a fraction of US tuition.
TU Delft in the Netherlands consistently ranks in the global top 50 for computer science. Bachelor's tuition for non-EU students is about €20,000 a year. Four years total about €80,000, roughly a third of an Ivy League degree.
Technical University of Munich (TUM) is tuition-free for EU citizens and costs €6,000 a year for non-EU students. Its CS program is taught partly in English and ranks in the global top 50.
ETH Zurich ranks in the global top 10 for CS, alongside Stanford and MIT, with tuition of about CHF 1,500 a year. The hard part is getting in, not paying.
KU Leuven in Belgium and Trinity College Dublin complete the European shortlist of English-taught programs with strong industry links.
Rankings: QS World University Rankings, Computer Science.
Graduates of TU Delft, TUM, ETH, and KU Leuven start on about €55,000 to €80,000 in Northern Europe, which is competitive with US offers. Over a four-year degree, the tuition difference can exceed €200,000.
A reality check
Two challenges deserve a straight answer.
- Imposter syndrome and constant learning. Almost every CS student, and most professionals, feel at some point that they are not smart enough to belong. It is common, and persistence gets people through it. The languages and tools taught in college will change, so the most useful skill is learning how to learn.
- Belonging. Tech has well-known diversity problems. A student's background and perspective are an asset to the field, not a barrier. Products that work for everyone need builders from every background. A stereotype is a poor reason to rule out a field.
How to prepare in high school
- Math first. Take AP Calculus (AB or BC). AP Statistics helps too, especially for AI or data science.
- Take a CS class. AP Computer Science A, which teaches Java, or AP Computer Science Principles, a broader overview. Either one shows whether you enjoy coding.
- Build something. The most important step: start a personal project, however small. Try an Hour of Code on Code.org, build a club website with freeCodeCamp, or learn Python basics on Codecademy. A finished project shows interest and persistence, the two traits CS rewards most.
