What is GPA?
GPA, or Grade Point Average, is a single number that summarises academic performance across all courses, weighted by credit hours. On the standard US 4.0 scale, each letter grade maps to a fixed number of grade points. A semester GPA covers one term. A cumulative GPA averages every term across your degree.
Universities, scholarship boards, and employers use GPA as a quick measure of academic performance. A 3.5 usually qualifies for the dean's list. A 3.0 is a common floor for graduate program eligibility, and 2.0 is the minimum for good academic standing at most US institutions.
Understanding your result
Your semester GPA is a number between 0.0 and 4.0. Here is what the common ranges generally mean at most US colleges and universities:
| GPA range | What it typically means |
|---|---|
| 3.7 to 4.0 | Dean's list and summa cum laude territory |
| 3.5 to 3.6 | Strong, competitive for most graduate programs |
| 3.0 to 3.4 | Solid standing, meets most scholarship floors |
| 2.5 to 2.9 | Satisfactory; check if your major sets a higher minimum |
| 2.0 to 2.4 | Minimum good standing at most schools |
| Below 2.0 | Academic probation risk; check your institution's policy |
Grade requirements vary by institution, department, and program. Always confirm thresholds with your registrar or academic advisor.
How is GPA calculated?
GPA is calculated by multiplying each course's credit hours by the grade points earned, adding those products together, then dividing by the total number of credit hours.
Formula: GPA = Σ(Credit Hours × Grade Points) ÷ Σ(Credit Hours)
Step-by-step example
Three courses, one semester:
| Course | Credits | Grade | Grade points | Quality points |
|---|---|---|---|---|
| English Literature | 3 | A | 4.0 | 12.0 |
| Calculus | 4 | B+ | 3.3 | 13.2 |
| Modern History | 3 | A− | 3.7 | 11.1 |
| Total | 10 | 36.3 |
GPA = 36.3 ÷ 10 = 3.63. The 4-credit Calculus course carries more weight than the 3-credit courses. A B+ in a 4-credit class pulls the average further than the same grade in a 2-credit elective would.
How to use this calculator
- Choose your input mode (letter grade or percentage) using the toggle above the table.
- Enter the credit hours for each course in the Credits column.
- Select your letter grade from the dropdown, or type your percentage score.
- Click + Add course for every additional class.
- Your GPA updates live in the result box below the table.
Course names are optional. They help you keep track, but the calculation does not need them.
When to use this calculator
Use it at the end of a semester to check your GPA before grades officially post. Use it mid-semester to see your current standing and work out whether you can still hit a target. If you can, the Final Exam Calculator will tell you the score you need on each remaining exam. When you are preparing a graduate school application, run it to verify the GPA you plan to report. For GPA across multiple semesters, use the Cumulative GPA Calculator.
Common mistakes
Entering raw marks instead of letter grades. The calculator needs a letter grade or percentage, not a score like 72/100. Convert first, or switch to percentage input mode.
Confusing credit hours with contact hours. A 3-credit course that meets four times a week still counts as 3 credits. Use the credit value from your transcript or course registration page, not the number of weekly sessions.
Leaving out failed courses. An F is worth 0.0 grade points but the credit hours still count in the denominator. Excluding them makes your GPA look higher than it is.
Mixing scales. This calculator uses the US 4.0 scale. If your university uses a 5.0 or 10.0 scale, results will not be accurate. For CGPA on a 10.0 scale, use the CGPA to GPA converter.
GPA vs CGPA vs percentage
GPA on a 4.0 scale is the standard at US colleges and universities. CGPA is more common in India and Pakistan and may be on a 4.0, 5.0, or 10.0 scale depending on the institution. To convert a CGPA to a percentage, use the CGPA to Percentage tool. To convert an Indian or Pakistani CGPA to a US 4.0 GPA for a foreign application, use the CGPA to GPA calculator.
