Use the grade-point scale required by your school.
GPA = Σ(Grade points × Course credits) ÷ Σ(Course credits)The calculator applies the formula shown below and rounds the displayed answer for readability. Institutional grading rules, date conventions or required decimal precision may differ, so users should follow the rule used by their school, employer or form.
A GPA Calculator converts your course grades (and potentially credit hours) into a Grade Point Average (GPA). The process takes letter grades, converts them into grade points, sums the weight of your quality points by total credits for each course, and then divides this summed quality point value by the total credit hours in which you attempted the course(s).
Using the normal unweighted U.S. 4.0 GPA scale: An A grade is valued as 4.0 grade points, a B grade is valued as 3.0 grade points, C grade is valued as 2.0 grade points, D grade is valued as 1.0 grade points, and an F grade is valued as 0 grade points. Grading scales can be altered, and most colleges may use plus and minus as well as weighted GPAs, so go with the specific guidelines for grade point scale at your school if those options are given.
GPA is an average of grade points weighted by credit hours. So a higher number of credits has a more influence than lower number ofcredits.
Example: A 4.0 in a 3-credit hour course is equal to 12 quality points. This same 4.0 in a 1-credit hour course only accounts for 4 quality points.
When the number of credits for each course is similar, theGPA would just be the simple arithmetic mean of each grade’s value. If the numbers of credits in each course varied, use a weighted average.
The standard weighted GPA formula is:
GPA = Total Quality Points ÷ Total Credit Hours
Equivalently:
GPA = (G1C1 + G2C2 + ... + GnCn) ÷ (C1 + C2 + ... + Cn)
Where:
On a common 4.0 scale, a simplified grade-point table is:
| Letter Grade | Typical Grade Points |
|---|---|
| A | 4.0 |
| B | 3.0 |
| C | 2.0 |
| D | 1.0 |
| F | 0.0 |
Several U.S. Schools, colleges and universities differ in their GPA assignments for grade such as: A- ,B+ , B-, and C+ . An example could be 3.7 for A- , 3.3 for B+ and 2.7 for B- . Since academic policies of assignment will vary, your grade-point assignments should match those at the school or university you are attending.
Suppose a student completes four courses with the following grades and credit hours:
| Course | Grade | Grade Points | Credits | Quality Points |
|---|---|---|---|---|
| Course 1 | A | 4.0 | 3 | 12.0 |
| Course 2 | B | 3.0 | 4 | 12.0 |
| Course 3 | A | 4.0 | 3 | 12.0 |
| Course 4 | C | 2.0 | 2 | 4.0 |
Step 1: Calculate quality points for each course.
Course 1: 4.0 × 3 = 12.0
Course 2: 3.0 × 4 = 12.0
Course 3: 4.0 × 3 = 12.0
Course 4: 2.0 × 2 = 4.0
Step 2: Add the quality points.
12.0 + 12.0 + 12.0 + 4.0 = 40.0 quality points
Step 3: Add the credit hours.
3 + 4 + 3 + 2 = 12 credit hours
Step 4: Divide total quality points by total credits.
GPA = 40.0 ÷ 12 = 3.333...
GPA ≈ 3.33
Using the stated 4.0 scale and rounding to two decimal places, the student's GPA is 3.33.
If all courses have the same number of credits, the calculation is simpler. Suppose a student receives A, B, B, and C, with each course worth the same number of credits.
The grade points are 4.0, 3.0, 3.0, and 2.0.
GPA = (4.0 + 3.0 + 3.0 + 2.0) ÷ 4
GPA = 12.0 ÷ 4
GPA = 3.00
Because all courses have equal credit weight, a simple average produces the same result as a credit-weighted calculation.
GPA's are numeric values derived from grade points and not a percentage. GPA of 3.50 on a 4.00 scale means that the student's weighted grade points average at 3.50.
The displayed GPA may contain decimals because the result is an average. For example, 40 quality points divided by 12 credits produces 3.333..., which may be displayed as 3.33 when rounded to two decimal places.
It's very important to respect rounding. Your calculator may say 3.33, for instance, but the actual value may actually be 3.333333.... For all official academic purposes, stick with the GPA calculated by your institution and substitute it, rather than recalculating rounded value.
Weighted and unweighted GPA are different. An unweighted GPA generally evaluates grades on a standard scale, while a weighted GPA may give additional grade points for advanced, honors, AP, IB, or other designated courses. The exact rules depend on the institution.
Students can use a GPA Calculator to get an approximate semester GPA, test the impact of certain grades, create an academic plan or see the impact of credit hours.
Another example is when you are reviewing calculated semester and cumulative GPAs and would like to see how you compare your one to your semester gpa. One thing that an institutional cumulative calculation is privy to, but a general calculator does not know, is institutional stipulations surrounding transfer grades, repeated classes, withdrawals, the presence of pass/fail classes, and more.
GPA, in the context of colleges and schools means the Grade Point Average. Grade Point Average means the average value of the grade points of a student's courses calculated in the GPA.
Each course's credit points times it's credit hours equals and added to give the quality points, then divide by total credits:
The standard U.S. Unweighted GPA scale runs from 0.0 to 4.0, with a maximum of 4.0 for an A, and a minimum of 0.0 for an F. GPA scales vary from one institution to the next, and some schools incorporate plus and minus ratings as well.
The 3.5 GPA stands for the weighted average of your relevant grade points. What particular grade combination results in a 3.5 is dependent on your individual class credits and rating scale.
Yes. Weighted when using credit hours, meaning a 4 credit course at a C will contribute 4 times that of a 2 credit course with the same GPA.
An unweighted GPA normally adheres to a standard 4-point grade-point scale, whereas a weighted GPA could add extra points for advanced courses that the school has deemed "weighted".
Enter a simple known case first to confirm the expected result, then calculate the real values. Keep the same units and avoid rounding intermediate values when precision matters.
A semester GPA reflect the grades earned in a single semester. All other GPA are calculated on the cumulative GPA which include selected courses for selected semesters. Since your cumulative grade is dependent on all the previous work you completed (both credit and grade point), a new semester can change your GPA but still leaves you with your GPA from a prior semester.
Quality hours on your record. In calculating an overall GPA, sum your quality points for all courses included in your overall GPA computation and divide by the total grade point hours earned on your record that may have been included in the calculation.
Cumulative GPA = Total Cumulative Quality Points ÷ Total Cumulative GPA Credits
For example, if a student has 90 quality points from 30 GPA credits, the cumulative GPA is:
90 ÷ 30 = 3.00
A new semester's effect depends on your new GPA and the amount of credits you've done. A new GPA above the existing cumulativeGPA usually pushes it up, and a new GPA below it usually pulls it down.
For example, if the student currently has a cumulative GPA of 3.00 for 60 credit hours and earns a 3.50 for an additional 15 credit hours ...
Previous quality points = 3.00 × 60 = 180
New semester quality points = 3.50 × 15 = 52.5
Total quality points = 180 + 52.5 = 232.5
Total credits = 60 + 15 = 75
New cumulative GPA = 232.5 ÷ 75 = 3.10
Calculate a target GPA by using the weighted average formula to find out the required number of future credits with specific GPA.
If a student currently has a GPA of Gc over Cc credits and expects to earn Gn over Cn future credits, the projected GPA is:
Projected GPA = (GcCc + GnCn) ÷ (Cc + Cn)
This can be helpful for an academic plan, but what will likely happen might differ for schools with special circumstances around repeated coursework, disregarded courses or courses without grade reports.
GPA is an average that is affected by the different number of credits a class or classes carry. Your grade in a class worth more credits will carry more quality points than if it was received in a low credit class.
So an A (4.0) in a four-credit hour course earns sixteen quality points while an A in a one-credit hour course earns 4 quality points.
No, there is no mathematical equivalent for converting GPA to percentage. You should not assume that a 4.0 GPA translates to a 100% and a 3.0 GPA is equal to 75% based on the above formula.
GPA and percentage are not really the same concept. If an organization ( or school) requires a GPA to percentage conversion use there conversion method ( since there isnt one standard one. )
Any assigned letter grade may be converted based on its corresponding grading system before calculation to get a student's overallGPA (GradePoint Average), with a typically Used4.0scaleassign different value to an A+, an A, an A-, a B+, a B, and a B-.
If a school gave 4.0 as its maximum value, and the school awarded an A- of 3.7. If one instead used 4.0 the final GPA will thus vary accordingly. Take the school as it provides the grade points values of the letter given by the institution.
Weighted calculation is necessary for varied credit values. This is because the addition of grade points and division by the number of subjects can create a wrong GPA calculation.
For example, consider a 4.0 grade in a 4-credit course and a 2.0 grade in a 1-credit course:
Quality points = (4.0 × 4) + (2.0 × 1) = 18
Total credits = 4 + 1 = 5
GPA = 18 ÷ 5 = 3.60
The simple average of 4.0 and 2.0 would be 3.00, demonstrating why credit weighting matters.
Suppose the exact calculation produces a GPA of 3.166666.... If the result is displayed to two decimal places, it becomes 3.17.
However, many often keep the unrounded values and simply display the final average GPA. Some official transcript systems also have their own rounding and reporting criteria for calculated GPAs.
