Caltech vs UC Berkeley: Acceptance Rates

When you’re comparing Caltech against UC Berkeley, one of the deciding factors you need to look at is how competitive admissions are at each school. Acceptance rates give you a quick look at just how selective these two institutions are and how different the odds can be depending on where you apply.

Here’s a look at the admissions trends for the Class of 2029:

Here’s how acceptance rates have shifted over the past three years:

• Caltech’s acceptance rate was 3.1% for the Class of 2027, tightened to 2.3% for the Class of 2028, and then rose to 3.8% for the Class of 2029. Even with this year-to-year movement, Caltech continues to admit well under 4 out of every 100 applicants, reinforcing its position as one of the most selective colleges in the country.
• UC Berkeley’s acceptance rate was 11.7% for the Class of 2027, then dipped to 11.0% for the Class of 2028, where it remained for the Class of 2029. While Berkeley’s acceptance rate is higher than Caltech’s, the sheer size of its applicant pool still makes admission highly competitive.

Both Caltech and UC Berkeley are tough to get into, but for different reasons. Caltech’s challenge comes from its tiny class size and extreme selectivity, while Berkeley’s comes from massive demand.

Caltech vs UC Berkeley: Rankings

While rankings shouldn’t be the only factor for choosing a college, they’re still useful when comparing Caltech and UC Berkeley, especially if you care about academic reputation, research output, and long-term outcomes after graduation.

Here’s how both schools stack up across major ranking systems:

Let’s break down what each ranking actually says about Caltech and UC Berkeley.

U.S. News (National Universities)

• Caltech: #11
• UC Berkeley: #15

U.S. News places significant weight on measures like graduation rates, first-year retention, faculty resources, and overall student success—all of which Caltech scores highly in.

Caltech’s freshman retention rate of roughly 97–98% signals that students are well supported and academically matched to the institution, a key indicator of educational quality in the rankings. Its six-year graduation rate of about 93–94% further reinforces consistent student persistence, even within an academically intense, STEM-heavy environment.

While Caltech’s four-year graduation rate is slightly lower at around 79–80%, this is common for highly rigorous programs and does little to diminish its overall standing given the strength of its long-term outcomes.

UC Berkeley also performs well on the outcome measures emphasized by U.S. News, especially for a large public research university. With a freshman retention rate near 97%, Berkeley demonstrates strong first-year student engagement and institutional support, both of which are heavily weighted in rankings methodology.

Its six-year graduation rate of approximately 93% places it on par with top private universities. A four-year graduation rate of around 80% is particularly notable given Berkeley’s size and academic breadth. Together, these metrics support Berkeley’s consistently high national rankings, demonstrating that scale does not come at the expense of student success.

Takeaway: If national rankings and institutional resources matter most to you, Caltech comes out ahead.

Times Higher Education (World University Rankings)

Caltech vs UC Berkeley: Campus Life

Campus life shapes how you spend your time outside the classroom and how connected you feel to your school.

Here’s a quick look at how the Caltech and UC Berkeley campuses differ:

Caltech campus life

Caltech’s campus experience is tight-knit and academically focused. With roughly 1,000 undergraduates, the community is small enough, and campus life revolves more around shared coursework and research than a traditional college social scene. The school is located in Pasadena, a residential city just outside Los Angeles.

Most students live on campus for all four years, and student life is organized around Caltech’s House System, where undergraduates are placed into one of eight residential houses, including Ricketts, Dabney, Fleming, and Blacker. These houses serve as the center of social life, peer support, and campus traditions.

Student organizations are fewer in number compared to large universities, but they are active and highly specialized. Many reflect Caltech’s technical culture, with groups like the Caltech Robotics Team, Caltech Coding Club, Women in STEM, and the Society of Women Engineers, alongside ASCIT-supported cultural and identity-based organizations. Athletics compete at the Division III level.

UC Berkeley campus life

UC Berkeley’s campus life is large and full of entry points, especially if you live on campus your first year. New students typically start in residence halls like Unit 1, Unit 2, Unit 3, or Foothill, and you can also apply to one of eight Theme Programs that group you with students around shared academic interests, cultural identities, or personal goals.

These communities often connect students to related organizations and initiatives across campus, such as the Public Service Center, Berkeley Global, and identity-based student groups supported by the Multicultural Community Center.

Student support and wellness are centralized through the Tang Center, which provides medical care, counseling, and preventive services, all covered under the Berkeley Student Health Insurance Plan, including mental health, dental, and vision care.

Berkeley also offers family student housing for those with partners or children, with access to childcare services and family-focused community spaces. After the first year, many students move off campus, and the university supports that transition through the Off-Campus Rental Service, which helps students find housing, connect with roommates, and navigate leases and budgeting.

Caltech vs UC Berkeley: Cost of Attendance

Paying for college is a major consideration, especially when you’re comparing a private institution like Caltech with a public university like UC Berkeley. The price difference can be significant.

Here’s what one year at each school might cost you:

California Institute of Technology is the more expensive option overall. With an estimated annual cost of $93,912–$97,455, Caltech costs roughly $46,500 to $51,000 more per year than University of California, Berkeley for a California resident.

Even compared to Berkeley’s nonresident cost ($85,758–$86,658), Caltech is still about $7,300 to $11,700 more per year.

Over four years, the difference adds up fast. A California resident attending UC Berkeley could save roughly $186,000 to $204,000 compared to attending Caltech. Even a nonresident student at Berkeley would save about $29,000 to $47,000 over four years.

Cost of attendance at Caltech

The California Institute of Technology estimates an annual cost of attendance between $93,912 and $97,455, with the variation mainly driven by housing choices. Tuition is set at $65,622, along with $2,586 in required fees. On-campus housing is estimated at $12,105, while off-campus housing rises to about $15,219. Meal costs average $8,886 for students living on campus and about $7,533 for those off campus.

Students should also budget roughly $1,428 for books and course materials, plus personal expenses that range from $3,285 on campus to $5,067 off campus, accounting for the overall difference in total cost.

Cost of attendance at UC Berkeley

University of California, Berkeley estimates that California residents living on campus face a total annual cost of $47,388. This includes $15,588 in tuition, $1,800 in campus fees, $21,200 for housing and meals, $3,700 for health insurance, $1,400 for books and supplies, and about $3,700 for personal transportation and other expenses.

For California residents living off campus, the estimated total cost drops slightly to $46,488. Tuition is $54,858, campus fees remain $1,800, while housing and meals decrease to about $19,500. Books and supplies are estimated at $1,400, health insurance at $3,700, and personal and transportation expenses rise to approximately $4,500.

For nonresident students living on campus, UC Berkeley estimates a total annual cost of $86,658. This reflects $54,858 in tuition, $1,800 in campus fees, $21,200 for housing and meals, $3,700 for health insurance, $1,400 for books, and around $3,700 in personal and transportation costs.

For nonresident students living off campus, the estimated total cost is slightly lower at $85,758. Tuition and fees remain unchanged, while housing and meals decrease to $19,500. Books and supplies are again estimated at $1,400, health insurance at $3,700, and personal and transportation expenses at roughly $4,500.

Caltech vs UC Berkeley: Financial Aid and Scholarships

Financial aid plays a major role when choosing between Caltech and UC Berkeley, especially since Caltech’s sticker price is significantly higher than Berkeley’s, particularly for California residents.

Both schools offer ways to reduce the cost of attendance, but how aid is awarded, and who benefits most, differ because Caltech is privately funded while Berkeley operates within a public university system.

Caltech financial aid and scholarships

Caltech uses a need-blind admissions process for U.S. citizens and permanent residents and commits to covering 100% of demonstrated financial need for admitted students. Even though Caltech has a higher sticker price, financial need is not a factor in admissions decisions, and aid is structured to make attendance realistic once you’re accepted. For the fall 2024 class, the average grant aid was just under $73,000.

Caltech’s financial aid is designed to remove cost as a barrier for admitted students. For U.S. applicants, your ability to pay is not considered during the admissions process, and all assistance is awarded strictly based on demonstrated need rather than merit.

Aid packages are built primarily around grants, which do not need to be repaid, with only limited reliance on work-study or student loans. In practice, students from families earning under $100,000 per year, assuming typical assets, often receive no-loan packages that fully cover tuition, fees, housing, and meals.

UC Berkeley financial aid and scholarships

UC Berkeley offers financial aid to help cover tuition and living costs, with over 60% of undergraduates receiving some form of aid. Support comes from a mix of grants, scholarships, loans, and work-study, making Berkeley more affordable for many students, especially California residents.

UC Berkeley’s financial aid combines multiple sources to help students manage costs. Grants and scholarships from federal, state, and university programs form the foundation of aid packages and do not need to be repaid. If there are remaining expenses after grant aid, students may use federal student loans to help cover the difference.

Berkeley also offers work-study and campus employment opportunities, including positions in research labs, tutoring centers, and administrative offices, allowing students to earn income while enrolled. In addition, specialized programs such as Graduate Dream Act Aid provide financial support for eligible students who do not qualify for federal aid.

Final Verdict: Caltech vs UC Berkeley

Both Caltech and UC Berkeley offer top-notch academics, but they deliver very different college experiences. Looking at academic structure, campus life, and cost side by side helps clarify which environment will allow you to do your best work over the next four years.

Choose Caltech if you’re looking for a small, highly focused academic environment with fewer than 1,000 undergraduates and an ultra-low 3:1 student-to-faculty ratio. The curriculum is entirely STEM-based, with intensive math and science requirements built into every major. Research is a core part of the undergraduate experience, often starting as early as your first year, with funded opportunities available.

Campus life is shaped by a close-knit residential culture centered on the House System, where most students live on campus all four years. Caltech also offers strong need-based financial aid, does not award merit scholarships, and provides no-loan aid packages for many families earning under $100,000.

Choose UC Berkeley if you want broad academic flexibility, with more than 300 degree programs across 15 schools and colleges that let you explore fields ranging from engineering and computer science to the social sciences and humanities. Academically, you’ll experience a mix of large introductory lectures and smaller upper-division courses, with over half of Berkeley’s classes enrolling fewer than 20 students, giving you both scale and depth as you progress.

The campus offers a classic public-university environment, with access to hundreds of student organizations, major research labs, cultural events, and extensive study-abroad opportunities. Berkeley also offers a more affordable path to a top-tier education, especially for California residents, and over four years can cost nearly $200,000 less than Caltech, with significant savings even for nonresidents.

When you make your decision, focus on the environment where you’ll feel most supported and motivated. Both options can lead to strong outcomes, but the right choice comes down to the kind of college experience you want for the next four years.
