The differences that decide what you pay and what you can do afterwards are structural, and every one of them is published.
Every figure below is from a government department or from the university that charges it.
Length
How long is a bachelor's degree in each country?
In the US, the Department of Education's own definition of a bachelor's degree is one "usually requiring at least 4 years (or equivalent) of full-time college-level study."
UK degrees are commonly shorter. Oxford's undergraduate course listing shows degrees at 3 years, at 4 years, and at "3 or 4 years" where a year abroad or an integrated master's is involved. Check the length on the course page of each university you are considering, because it is set course by course rather than nationally.
This is the difference that moves the most money, and it moves it before anyone has compared a single fee. A US degree is a year longer. At the same annual cost, that is 33% more.
It also changes what you are signing up for. A Borderless student who did two master's degrees at Oxford on a Rhodes Scholarship puts the difference this way: "The US education system offers more breadth and flexibility in choosing majors, while the UK system is more focused on a specific subject."
Tuition
What do universities charge international students?
The two countries publish different things, which is why comparisons go wrong.
UK universities publish a course fee. Oxford's published overseas fee for 2027-28 entry is between £39,620 and £66,580 a year, depending on the course, against £10,050 for a Home student. Its own page tells overseas applicants they "will not be eligible for a tuition fee loan from the UK government."
US universities publish a cost of attendance, which bundles tuition, housing, food, insurance and books. UC Berkeley's figure for a new student in 2026-27 is $54,674, and every non-resident adds the University of California's Nonresident Supplemental Tuition of $39,270, bringing a Berkeley year to $93,944.
So a UK fee and a US cost of attendance are not the same measurement. Add UK living costs to the UK number before you compare, and check whether a US figure is the in-state one, because at a public university the headline total usually is. Our guide to what US universities cost international students covers that trap in detail.
Applying
What does it cost to apply to each?
This gap is the widest of any figure on this page.
| Cost | |
|---|---|
| UCAS, up to five UK universities | £34.50 |
| Ten US universities, with CSS Profile and one SAT sitting | about $1,235 |
UCAS charges £34.50 for up to five choices for 2027 entry, in one payment. The US figure is our arithmetic on published fees: nine University of California campuses at $95 each for international applicants, one private at $100, CSS Profile at $25 plus $16 for each additional university, and an SAT taken outside the US at $111. Our post on what it costs to apply shows the full breakdown and which fee waivers reach international students.
That £34.50 covers up to five choices, so extending a UK list costs nothing until you reach the limit. A US list gets more expensive with every university you add.
Working during the degree
How many hours can you work?
Both countries allow 20 hours a week during term. The difference is where.
In the UK, the Immigration Rules allow degree-level students "20 hours per week during term-time (full-time employment permitted outside of term-time)". The work does not have to be at the university, though gov.uk excludes self-employment and some roles such as professional sport.
In the US, the Department of Homeland Security limits F-1 students to on-campus employment, where "you may not work more than 20 hours per week when school is in session." Off-campus work requires having completed "at least one full academic year" and demonstrating economic hardship under DHS emergent circumstances, then filing Form I-765 and waiting for authorisation, and you "cannot begin to work while the Form I-765 is pending."
So in the UK you can take an ordinary job off campus in your first term. In the US you cannot, in your first year, in almost all cases.
After you graduate
How long can you stay and work?
The UK Graduate visa lasts "2 years if you apply on or before 31 December 2026" and "18 months if you apply on or after 1 January 2027", with 3 years for doctoral graduates. It costs £937, plus the healthcare surcharge.
US Optional Practical Training gives up to 12 months of employment authorisation, and graduates of eligible STEM degrees can apply for "a 24-month extension" on top, which requires the employer to be enrolled in E-Verify.
The comparison depends entirely on your subject. A UK graduate gets 18 months from 2027 whatever they studied. A US graduate gets 12 months, or 36 months if their degree is on the STEM list and their employer qualifies.
Visas
What does the visa itself require and cost?
The UK. A Student visa costs £558 applying from outside the UK. The immigration health surcharge is £776 per year for students, which buys NHS access. English has to be at CEFR level B2 for degree-level study, proven by an approved test or assessed by the university itself.
The US. The I-901 SEVIS fee is $350, paid before the visa application. The harder requirement is not a fee. US law presumes every applicant intends to immigrate, and you have to satisfy a consular officer otherwise at an interview. Our post on the student visa interview and refusals covers what that involves.
The UK requirements above are things you evidence on paper. The US adds a decision made in person, by an officer who starts from a presumption against you.
Teaching and assessment
How are you graded in each country?
This is the difference students notice once they arrive, and it rarely appears in a cost comparison.
The Rhodes Scholar quoted above studied in both systems and describes the contrast directly: "In the US, students are graded on various aspects, including participation, attendance, and quizzes, providing opportunities for growth and improvement. In the UK, grades are heavily based on final exams, which can create a high-pressure environment."
The same account notes a social difference: "Campus culture is stronger in the US, with fraternities, sororities, and societies playing a significant role in student life. London universities, in particular, lack the campus vibe due to their spread-out nature within the city."
Neither is better. They suit different students, and a student who performs badly in single high-stakes exams should know that before choosing a country where the degree rests on them.
Money from the university
Which country funds international students?
This is where the US, for some students, becomes the cheaper option despite everything above.
US universities award their own institutional aid, and at the wealthiest ones the sums are large. In their Common Data Set filings, Amherst reports an average grant of $63,759 and Princeton $62,593. You apply for it through the CSS Profile, and it varies enormously by university, because federal aid is closed to F-1 students entirely.
In the UK, Oxford states the position for overseas students plainly on its fees page: no UK government tuition fee loan. Check each university's own scholarship pages for what it offers instead, because that is where UK support for overseas students is published.
The practical consequence is that the US has a wider spread. It contains both the most expensive outcome and, for a student who wins institutional aid, potentially the cheapest.
When the aid does not arrive, students move. Mary from Armenia was accepted to the University of Minnesota and describes what happened next: "I didn't receive much financial aid, so I decided to consider European universities for the following year." She applied across both continents, "received more funding in Europe", and went there.
How to choose
Start from the length. Three years against four is the one difference that applies no matter which universities you pick.
Compare like with like. A UK course fee plus living costs against a US cost of attendance. Comparing a fee to a cost of attendance will mislead you every time.
Count the applications. Five UK choices for £34.50 means a UK list costs almost nothing to extend. A US list gets more expensive with every university you add.
Check your subject against the STEM list if the years after graduation matter to you, because that single fact swings the US from 12 months to 36.
Work out whether you are a candidate for US institutional aid before ruling the US out on sticker price, and whether you are a candidate for a UK scholarship before assuming the UK is the affordable one.
Start your own journey
The honest answer is that neither country is cheaper in general. The UK is shorter, far cheaper to apply to, and more predictable. The US is longer and more expensive on paper, and institutional aid can change that number completely.
Decide which of those you can plan around, then build the list.
