The average cost of college tuition per credit hour is $456.
Four-year private nonprofit colleges charge the highest tuition at almost $1,200 per credit hour.Footnote 
Two-year public schools, or community colleges, charge the least at just under $120 per credit hour.Footnote 
Online colleges may charge less money per credit hour compared to all schools.
College classes are typically three credit hours for students on a semester system, but this varies.
A college credit typically equals three weekly hours of students' time in class or completing coursework outside of class.
The average college tuition is close to $19,000 a year for full-time students at four-year colleges. But what if you're a part-time student or just taking a few classes? That's when it's important to know your school's cost per credit hour.
Credit hours correspond to how much work you're expected to do for a college course per week. One credit hour typically equals one hour of class time and two hours of work outside of class, such as homework, lab work, or a student internship.
Colleges and universities often have thresholds for when students pay tuition by the credit hour versus paying a flat rate. A part-time student might pay by credit hour. Meanwhile, a full-time student might pay the same flat rate once they reach a certain number of credits regardless of whether they take extra classes to graduate early.
It's helpful to know your school's policy because it can make getting your degree more affordable. Keep reading to find the average cost colleges charge for credit hours, so you can better balance your course load and your budget.

Average Cost Per Credit Hour
Below, we've calculated the average cost per credit hour based on the average cost of college in the U.S. with a couple of assumptions:
- Most schools use semesters versus quarters. Semester-system schools have two 15-week terms, one in the fall/winter and one in the spring. Quarter-system schools have four 10-week terms, including an optional summer term. If you're in a semester system, you need fewer credits to earn your degree (120 for bachelor's) compared to students in the quarter system (180).
- Students complete 30 credits per year. Most accrediting bodies require students to complete 120 credits for a bachelor's degree, which typically takes four years. Associate degree programs require at least 60 credits and last about two years.
Tuition Per Credit Hour
Across all school types, the average college cost per credit is $456. However, credit hours are priced differently across institution types.Footnote 
- At four-year institutions, the average cost of tuition and fees per credit hour is $554.
- Credit hours are over $400 cheaper at two-year schools, where the average tuition per credit hour is $126.
- The most affordable college credits are at community colleges. The most expensive are at four-year private nonprofit schools. Credits at these schools cost over 10 times more than at two-year public schools.

Total Cost Per Credit Hour
College students encounter expenses beyond the cost of tuition alone. Textbooks, transportation, and room and board add up. To find the all-in cost of college per credit hour, we divided the average total cost of one year of college by 30.
- The average total cost of college per credit hour for students living on campus at four-year colleges is $1,185.
- The average cost per credit hour at all two-year schools is about half that of four-year schools, assuming similar living situations.
- Across school types, students save the most money when they can offset dorm expenses or rent by living with family.
Net Cost Per Credit Hour
Many college students receive financial aid in the form of scholarships or grants. Their net cost of college equals their total college price tag minus the amount of aid they receive.
In 2019-2020, the average net price of college per credit hour was $621 at four-year institutions and $303 at two-year institutions.
The net cost of college credit hours varies across institution types, as seen in the graph below. It also depends on students' income level. Lower incomes typically correspond to more financial aid.Footnote 
Historical Tuition Per Credit Hour
Fifty years ago, the average cost of college tuition per credit hour was about $147 — ranging from $42 at two-year public schools to $349 at four-year private schools.
Tuition per credit hour has grown over the years. Across all schools, the average cost of one credit hour has tripled since 1970. Two-year schools, including private schools and community colleges, have remained the most affordable option.
Cost of Online College Per Credit Hour
Students may try to save money by earning credit hours online, and sometimes they can. Thirty-three distance-learning-only institutions report their net price in the National Center for Education Statistics College Navigator database. Their average net price for a credit hour was $516. That's about $100 cheaper than the average for all schools in 2019-2020.
When comparing costs for online college credit hours, the type of school makes a difference. Online college credit hours are the most affordable at public institutions. Private for-profit schools charge the most.

Frequently Asked Questions About College Credit Hours
What does "per credit hour" mean in college?
When colleges list tuition costs "per credit hour," the amount students pay depends on how many college credits they enroll in for a given term. Usually, once a student is enrolled in a certain number of credits that's considered a full-time load, they pay a flat fee.
How many credits is one college class?
On a semester system, it's typical for college classes to equal about three credits. That way students can take an average of five courses per term to earn an associate degree (60 credits) in two years or a bachelor's (120 credits) in four.
That said, the amount of credits you earn for one college class varies. It depends on how much work you're expected to do for the class. One credit hour equals at least three hours of work per week, including class and out-of-class time.Footnote 
How much do college classes cost?
The cost of taking one college class usually depends on how many credits it's worth. On average, one college credit costs about $600 — that's $1,800 for your typical three-credit course. However, there is a massive difference in costs between college types.
Four-year private nonprofit universities might charge $1,200 or more per credit hour. In comparison, community colleges charge around $120 per credit hour, on average. That's $360 for a class.
