This calculator computes your GPA (Grade Point Average) on the standard 4.0 scale, using the credit-hour-weighted formula colleges and universities actually use. Enter a grade and credit-hour value for each course, and add your previous cumulative GPA and credits if you want a true running total instead of just this semester.
GPA is a weighted average, not a simple average of your grades: a 4-credit course affects your GPA twice as much as a 2-credit course, since more credit hours mean more quality points are riding on that grade. This is also why a single low grade matters less against a large total credit count than it does early in your academic record.
Below you will find the exact formula with a worked example, the difference between weighted and unweighted GPA, a full GPA scale reference table, and guidance on tracking your cumulative GPA across multiple semesters.
How GPA is calculated
Multiply each course grade (on a 4.0 scale) by its credit hours to get quality points. Add up the quality points for every course, then divide by the total credit hours. This weighted average is your GPA.
For example, an A (4.0) in a 3-credit course earns 12.0 quality points. A B+ (3.3) in a 4-credit course earns 13.2 quality points. Add those together (25.2) and divide by the total credit hours (7) to get a 3.60 GPA.
Weighted vs unweighted GPA
Unweighted GPA scores every course on the same 4.0 scale regardless of difficulty. Weighted GPA gives extra points for harder courses like AP, IB, or honors classes, often on a 5.0 scale, since an A in a harder course reflects more effort than an A in a standard one. If your school uses a percentage or a different scale entirely, convert it first with the International Grade Converter.
GPA scale reference table
This table shows the standard letter-grade-to-GPA conversion used across most US high schools and colleges:
| Letter Grade | GPA Points |
|---|---|
| A | 4.0 |
| A- | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B- | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| C- | 1.7 |
| D+ | 1.3 |
| D | 1.0 |
| F | 0.0 |
Tracking your cumulative GPA across semesters
Semester GPA only counts the courses from one term. Cumulative GPA factors in every credit hour and grade you have ever earned, including prior semesters, which is what most transcripts and graduate school applications actually report.
To calculate a true cumulative GPA, enter your previous cumulative GPA and total credits earned so far, along with this semester's new grades and credits. The calculator combines both into one running total.
Many colleges also require a minimum cumulative GPA to keep a scholarship, so it is worth checking that requirement directly with the Scholarship Savings Calculator if that applies to you. Need your final grade in just one class instead of your overall GPA? Use the Grade Calculator instead.
Frequently Asked Questions
How is GPA calculated?
Multiply each course grade (on a 4.0 scale) by its credit hours to get quality points. Sum all quality points and divide by total credit hours. This gives your weighted GPA.
What is the difference between weighted and unweighted GPA?
Unweighted GPA treats all courses equally on a 4.0 scale. Weighted GPA gives extra points for harder courses (AP, IB, honors), often on a 5.0 scale. Most college admissions offices recalculate GPAs using their own system.
What is the difference between semester GPA and cumulative GPA?
Semester GPA only counts courses from one term. Cumulative GPA includes every credit hour and grade you have ever earned across all semesters, which is what transcripts and graduate school applications typically report.
How do I calculate my cumulative GPA if I already have credits from a previous semester?
Enter your previous cumulative GPA and total credits earned so far, along with this semester's new grades and credits. The calculator combines both into one true cumulative GPA.
What GPA do I need for graduate school?
Most graduate programs require a minimum 3.0 GPA. Top programs (Ivy League, top-10 MBA, medical school) typically want 3.5 to 3.9 or higher. A strong upward trend in later years can help offset a lower early GPA.
What if my school uses a percentage or a different grading scale?
Convert your grades to the standard US 4.0 scale first, then enter the converted values here.
Does a low grade in one class ruin my GPA?
It depends on how many credit hours that class carries relative to your total. A single 3-credit F has much less impact on a 60-credit cumulative GPA than on a 12-credit semester GPA, since it is averaged across far more total credits.
