Caltech vs Harvard: Acceptance Rates

When you’re deciding between Caltech and Harvard, their admissions selectivity is one of the first factors to look at.

Here’s how the admissions landscape looks for the Class of 2029:

Here’s how selectivity has shifted at both schools over the past few years:

• Caltech’s acceptance rate was 3.1% for the Class of 2027, tightened to 2.6% for the Class of 2028, and then rose to 3.8% for the Class of 2029. Even with this increase, Caltech continues to admit fewer than 4 out of every 100 applicants, underscoring its position as one of the most selective colleges in the country.
• Harvard’s acceptance rate has remained highly competitive across recent admissions cycles, with a gradual upward shift. It stood at 3.4% for the Class of 2027, increased to 3.6% for the Class of 2028, and rose again to 4.2% for the Class of 2029. Even with this increase, Harvard also continues to accept only about 4 out of every 100 applicants.

Neither school is easier to get into. Caltech’s challenge lies in its extreme selectivity and small scale, while Harvard’s comes from global demand across many fields.

Caltech vs Harvard: Rankings

Rankings are helpful when you’re comparing two schools like Caltech and Harvard, especially if you care about academic reputation, research influence, and what doors a degree might open later on.

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

Let’s break down what these rankings say about Caltech and Harvard.

U.S. News (National Universities)

• Caltech: #11
• Harvard: #3

U.S. News (National Universities) places significant weight on outcomes such as graduation rates, first-year retention, faculty resources, and overall institutional support.

Under this framework, Harvard ranks #3 nationally. Harvard reports a graduation rate of about 97% and a first-year retention rate of roughly 99%. These figures align with U.S. News’ emphasis on long-term student success across a wide range of disciplines.

Caltech ranks #11 nationally and also reports strong outcomes, particularly given its small size and academic intensity. Caltech’s first-year retention rate is approximately 98%, and its six-year graduation rate is around 94%. While slightly lower than Harvard’s on paper, these numbers remain exceptionally high, especially for a STEM-only institution with a demanding core curriculum.

Caltech’s narrower academic scope and smaller undergraduate population can limit its performance on rankings that reward institutional scale and breadth, even though student persistence remains strong.

Takeaway: U.S. News favors Harvard’s scale, funding, and across-the-board outcomes, giving it a higher overall ranking. Caltech still delivers elite graduation and retention results, but rankings that prioritize breadth and institutional resources tend to advantage Harvard.

Caltech performs especially well on QS metrics tied to academic reputation within technical fields, even though its smaller size limits its reach across non-STEM industries.

Takeaway: QS favors Harvard’s global brand, cross-industry employer recognition, and international footprint, giving it the higher ranking. Caltech remains a top-tier institution, but its QS strength is concentrated in STEM and research-heavy careers rather than broad global visibility across fields.

Caltech vs Harvard: Academics

Caltech and Harvard are both academic powerhouses, but the way you learn at each school feels very different. To see which environment fits you better, it helps to look closely at how their academic models compare.

Let’s start by looking at their academic profiles:

Both Caltech and Harvard admit students with extremely strong academic profiles. Caltech doesn’t report an average GPA, so GPA cannot be directly compared across both schools. Despite that, since Caltech is a selective school, we can expect competitive applicants to have an unweighted GPA of 3.9 or higher.

Harvard’s SAT score range of 1510-1580 places it among the most academically competitive schools in the U.S. Caltech uses a bucket system that groups section scores into performance ranges.

Caltech academics

Caltech’s academic programs are best suited to students seeking a highly technical, STEM-focused education. It offers 28 undergraduate majors, most of them centered on science, engineering, and math—although there are a few humanities and social sciences courses, such as English, History, and Philosophy. Every student completes a rigorous core in math, physics, chemistry, and computation, giving everyone a strong shared academic foundation.

Caltech’s popular academic areas include:

• Computer Science
• Mechanical Engineering
• Physics, General
• Electrical and Electronics Engineering
• Computational Mathematics

With a 3:1 student-to-faculty ratio and fewer than 1,000 undergraduates, classes at Caltech are small and usually taught by senior professors. The school’s narrow focus is intentional, with research built into everyday academic life. Through programs like SURF (Summer Undergraduate Research Fellowships), students can start working on funded faculty research as early as their first year.

Harvard academics

Harvard academics follow a classic liberal arts model. You complete general education requirements across multiple disciplines before declaring a concentration. Most students take four courses per semester and graduate after completing 128 credits.

Harvard’s popular majors include:

• Social Sciences
• Biological and Biomedical Sciences
• Mathematics and Statistics
• Computer Science
• History

Harvard’s student-to-faculty ratio is 7:1, and most classes enroll fewer than 20 students. Expect discussion-based courses, regular interaction with professors, and flexibility to explore multiple fields before narrowing your focus.

Caltech vs Harvard: Campus Life

When comparing Caltech and Harvard, the biggest differences come down to campus size, location, and the pace of daily life. These factors shape everything from social opportunities to how you balance academics with downtime.

Here’s a quick look at how the two campuses compare:

Caltech is located in Pasadena, California, offering a compact, suburban campus near Los Angeles, while Harvard is based in Cambridge, Massachusetts, with an urban campus that is closely integrated with the city of Boston.

Caltech campus life

Caltech’s campus life is small and very focused. With about 1,000 undergraduates, it’s easy to know people, and the community feels centered on academics rather than a traditional college scene. The campus sits in Pasadena, a quiet area just outside Los Angeles.

Most students live on campus all four years, which helps create a close-knit environment. Student life revolves around the House System, where students are placed into one of eight houses, such as Ricketts, Dabney, Fleming, and Blacker, that serve as both residential and social communities.

Caltech has fewer student organizations than large universities, but the clubs are active and closely tied to STEM and specialized interests. Groups include the Caltech Robotics Team, Caltech Coding Club, Women in STEM, the Society of Women Engineers, and ASCIT-supported cultural and identity-based organizations. Athletics compete at the Division III level, but school spirit shows up more through house traditions and shared academic intensity than through big sporting events.

Harvard campus life

Harvard offers a larger, more varied social environment. First-year students live in dorms around Harvard Yard, forming built-in communities right away. Upperclassmen live in one of Harvard’s 12 residential Houses, such as Kirkland, Eliot, Leverett, Winthrop, and Quincy, each with its own dining hall, social events, academic advisers, and intramural sports teams that shape daily community life.

Student culture is driven by long-standing traditions like Housing Day and a wide range of organizations. Campus media groups such as The Harvard Crimson and The Harvard Lampoon are highly visible, alongside performance groups like the Harvard-Radcliffe Dramatic Club. Cultural and identity-based organizations are also active, including the Harvard Black Students Association, Harvard Asian American Association, Latino Men’s Collective, and Harvard College Women’s Center–affiliated groups.

Caltech vs Harvard: Cost of Attendance

Cost matters when you’re choosing between two private universities, even ones with massive endowments.

Here’s what a single year at each school typically costs before financial aid:

On sticker price alone, Caltech comes in higher than Harvard. Caltech’s total cost of attendance ranges from about $93,900 to $97,400 per year, while Harvard’s sits at roughly $86,900. That puts Caltech around $7,000–$10,000 more expensive each year. 

Over four years, that gap can grow quickly, especially if you’re relying on loans or family contributions. If cost is a deciding factor for you, Harvard has the lower upfront price.

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 driven mainly by housing choices. Tuition is $65,622, along with $2,586 in required fees. On-campus housing is estimated at $12,105, while off-campus housing increases to about $15,219. Meal costs average $8,886 for students living on campus and roughly $7,533 for those off campus.

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

Caltech lists a third housing category, which is living with parents. However, since the most common options for students are living on campus and off campus, those are the expenses we discussed above.

Cost of attendance at Harvard

Harvard’s estimated total cost of attendance is $86,926 per year. This includes $59,320 for tuition, $1,800 for health services, $13,532 for housing, $8,598 for meals, and $3,676 in student services and related fees.

Caltech vs. Harvard: Financial Aid and Scholarships

Financial aid can completely change your college decision, especially when comparing schools like Caltech and Harvard. Both come with high sticker prices, but they aim to cover 100% of demonstrated financial need. A big difference is Harvard’s massive endowment, which enables it to offer some of the most generous aid in the country.

Caltech financial aid and scholarships

Caltech’s financial aid covers 100% of demonstrated financial need for admitted U.S. citizens and permanent residents without considering their ability to pay.  For the fall 2024 class, the average grant award was just under $73,000.

All financial aid is need-based, since the school does not offer merit scholarships. Aid packages rely mostly on grants that don’t need to be repaid, with minimal use of work-study or loans. For many students from families earning under $100,000 per year with typical assets, aid often covers tuition, fees, housing, and meals through a no-loan package.

Harvard financial aid and scholarships

Harvard is need-blind in admissions and commits to meeting 100% of each admitted student’s demonstrated financial need. More than 55% of undergraduates receive need-based scholarships, and many families pay far less than the published cost, with recent aid recipients paying an average of about $15,700 per year.

Harvard has expanded its aid policy so that students from families earning $200,000 or less now qualify for free tuition. Meanwhile, families earning under $100,000 typically receive full coverage for tuition, room, board, and other billed expenses. All aid is need-based rather than merit-based, so many students graduate with little or no debt.

Final Verdict: Caltech vs Harvard

Both Caltech and Harvard are elite institutions with competitive admissions and rigorous academics, opening doors to many opportunities. However, which school you choose comes down to the academics and undergraduate life you want to experience.

Choose Caltech if you want a very small, STEM-only environment with fewer than 1,000 undergraduates and a 3:1 student-to-faculty ratio. The academic culture is intense and centered on math, physics, engineering, and computation across all majors, with research built into the undergraduate experience and funded opportunities often available as early as your first year.

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

Choose Harvard if you want a liberal arts education that gives you time to explore multiple fields before committing to a concentration. The university offers strong programs across STEM, the humanities, and the social sciences, along with clear pathways into areas like government, economics, and public service. Academically, you’ll find a mix of small, discussion-based classes and a wide range of course options supported by extensive campus resources.

Outside the classroom, Harvard offers a large and varied campus life with hundreds of student organizations and global opportunities. It also has one of the most generous financial aid programs in the country, allowing most students to graduate debt-free.

If you want depth and focus on science, Caltech may be the better fit. If you want flexibility, breadth, and a wider range of academic and extracurricular options, Harvard may make more sense. The best choice is the one that matches how you learn, what you want to study, and how you want to spend the next four years.
