Credit Hour Calculator
Planning your path to graduation is easier when you know exactly how many credit hours you still need and how long it will take at different course loads. This credit hour calculator asks for three numbers: the credits you have already completed and counted toward your degree, the credits you are currently enrolled in this term, and the total credits required for graduation in your program. The calculator subtracts completed and in-progress credits to show you the remaining credits needed after this semester, then estimates how many additional semesters you need at three common full-time credit loads: 12 credits per semester (the minimum for full-time status), 15 credits per semester (the standard pace for a four-year degree), and 18 credits per semester (an accelerated pace). Semester estimates are rounded up because you cannot attend a fraction of a semester. This tool is most useful for academic planning conversations with your advisor. Your official degree audit, available through your institution's student portal, is the authoritative source for graduation requirements.
Remaining credits needed: --
How remaining credits are calculated
Remaining = Required credits - (Completed + In-progress credits)
Semesters = Ceiling(Remaining / credits per semester)
After this semester, remaining credits will equal the required total minus all completed credits (including those currently in progress, assuming you pass them all).
Frequently asked questions
How many credit hours does a bachelor's degree require?
Most US bachelor's degree programs require between 120 and 128 credit hours. Some programs, particularly in engineering, architecture, nursing, or education, may require 130 or more. Check your institution's degree requirements, published in the academic catalog, for the exact credit hour total for your specific program and major.
What is the difference between a credit hour and a semester hour?
A credit hour and a semester hour refer to the same thing at most US institutions: one unit of academic credit typically earned by attending one 50-minute class session per week for a 15-week semester. Quarter-system schools use quarter credits, which convert at roughly 1.5 quarter credits per semester credit.
How many credit hours is full-time enrollment?
The US Department of Education defines full-time undergraduate enrollment as 12 or more credit hours per semester. However, to graduate in four years with a 120-credit degree, students typically need to complete 15 credits per semester. Many students take 15 to 18 credits per term to stay on track or graduate early.
Do credits in progress count toward graduation?
Credits currently being attempted count toward graduation only after they are successfully completed with a passing grade. Transfer credits, AP credits, dual-enrollment credits, and CLEP exam credits may also count toward your degree total, subject to your institution's policies.
Can I graduate early by taking more credits per semester?
Yes. Taking 18 credits per semester instead of 15 can reduce a standard 120-credit degree from eight semesters to fewer than seven. However, most institutions require a minimum GPA or departmental approval to enroll above a set credit cap (often 18 credits). Summer sessions can also accelerate graduation.
