Why GPA is important?

Though GPA is a standard measure, it can differ slightly between institutions. It's widely used by academic institutions and employers to assess and compare student performance. GPA plays a crucial role in: Scholarship awards and merit-based financial aid. Graduation honors and awards. Job interviews and admission decisions.

How to calculate a GPA?

GPA is typically calculated using a formula that involves converting grades to numerical values and then averaging them. Here's a simplified version of the process: Convert Grades: Each grade is converted to its numerical equivalent based on the grading scale used. Multiply Grades by Credits: Multiply each numerical grade by the number of credits or units for the corresponding course. Calculate Total Grade Points: Sum up all the grade points earned across all courses. Divide by Total Credits: Divide the total grade points by the total number of credits to get the GPA.

Where can I find a GPA calculator?

There are several online GPA calculators available that can help you quickly determine your GPA based on the grades you've earned in your courses. For example, our online GPA calculator.

How does the GPA calculator work?

The GPA calculator allows users to input their course grades and credits, supporting both letter and percentage grades. It then calculates the final GPA and can also compute weighted GPAs for letter grades and cumulative GPAs based on previous GPAs and credits.

Where can I learn more about different grading systems and GPA conversion?

For information on different grading systems and GPA conversions, you can refer to educational resources, including: Your school's academic guidelines and policies. Online resources like educational websites and forums. GPA conversion charts provided by academic institutions.

Now, to understand how this calculator calculates GPA (letter (both weighted & unweighted), percentage, cumulative) read the following section, where each of the GPA types is described & calculated with some practical data:

What Are the Types of GPA?

There are various types of GPAs, some of them are discussed below:

Weighted GPA: Factors in the difficulty of courses by assigning higher weights to harder classes.
Unweighted GPA: Treats all classes equally regardless of difficulty.
Cumulative GPA: The GPA considering all courses taken throughout one"s academic career.
Semester GPA: The GPA for a specific academic term or semester.
Overall GPA: The GPA considering all courses taken, including those outside the major.

Different Grading Systems

There are several grading systems commonly used in education:

1. Letter Grade

A grading system using letters (e.g., A, B, C, D, F) to represent the quality of a student's work. It is a fundamental method for assessing student performance. Students receive letter grades corresponding to their performance ranges, which also relate to GPA values on a 4.0 scale:

A (90-100%, GPA 4.0): Excellent
B (80-89%, GPA 3.0 - 3.9): Good
C (70-79%, GPA 2.0 - 2.9): Satisfactory
D (60-69%, GPA 1.0 - 1.9): Needs Improvement
F (0-59%, GPA 0.0): Fail

Anyway, the specific ranges and values can vary by institution. Understanding your institution's grading scale is important for accurately interpreting academic performance.

A. Unweighted Letter Grade

The unweighted letter grade system is a standard method for assessing student performance, where each course contributes equally to the overall GPA regardless of its difficulty.

How does it work? Well, in the unweighted grading system, all courses are graded on the same 4.0 scale, without considering the course level (regular, honors, AP, etc.).

How to Calculate Unweighted Letter Grade GPA?
To calculate your unweighted letter grade GPA, use the following formula:

GPA_{Letter-unweighted} = ^{(G1 × C1 + G2 × C2 + G3 × C3)} ⁄ _{(C1 + C2 + C3)}

Here,

Grades = G1, G2, G3
Credits = C1, C2, C3

Steps to Calculate Unweighted Letter Grades GPA

Multiply each grade by its corresponding credit.
Sum the results from step 1.
Sum the credits.
Divide the sum from step 2 by the sum from step 3.

Practical Example to Calculate Unweighted Letter Grades GPA

For example, to find the GPA for these courses:

Course	Credits	Grade
Maths	4	A
Chemistry	3	A+
Physics	3	B+
Biology	2	B-

First, convert grades to the 4.0 scale point values:

Maths: A = 4.0
Chemistry: A+ = 4.0
Physics: B+ = 3.3
Biology: B- = 2.7

Then, multiply grades by credits and sum them up:

[ (4 × 4.0) + (3 × 4.0) + (3 × 3.3) + (2 × 2.7) = 40.3]

Next, apply the formula:

GPA_{Letter-unweighted} = ^40.3 ⁄ _{(4 + 3 + 3 + 2)} =^40.3 ⁄ ₁₂ ≈ 3.358

B. Weighted Letter Grade

The weighted letter grade system takes into account the difficulty of the courses, offering a more nuanced measure of student performance by adding extra points for more challenging classes.

How does it work? Well, in a weighted grading system, different types of courses have different impacts on GPA. Typically, advanced courses such as Honors, Advanced Placement (AP), International Baccalaureate (IB), and College Prep courses add extra points to the GPA:

Regular Courses: Standard grading scale.
Honors Courses: Usually add 0.5 points to the grade.
AP/IB/College Prep Courses: Typically add 1 point to the grade.

How to Calculate Weighted Letter Grade GPA?
To calculate your weighted letter grade GPA, use the following formula:

GPA_{Letter-weighted} = ^{(G1 × C1 + G2 × C2 + G3 × C3)}⁄ _{(C1 + C2 + C3)}

Here,

Weighted Grades = G1, G2, G3
Credits = C1, C2, C3

Weights refer to the relative importance or contribution of each assignment or exam toward the overall grade in the course.

Steps to Calculate Weighted Letter Grades GPA

Convert Letter Grades to Grade Points. Use the standard scale (e.g., A = 4.0, B = 3.0, etc.).
Add Weight for Advanced Courses:
- Honors courses: Add 0.5 points.
- AP/IB courses: Add 1.0 points.
Multiply Grade Points by Course Credits.

Weighted Grade Points = Grade Points × Course Credits

Add all the weighted grade points from each course.
Sum the Course Credits.
Finally, calculate the Weighted GPA.

Practical Example to Calculate Weighted Letter Grades GPA

Suppose you received the following grades:

Course	Grade	Course Type	Weighted Grade Point	Credits
Maths	A	Honors (+0.5)	4.5 (4.0 + 0.5)	3
Biology	C+	Regular	2.3	3
History	B	Regular	3.0	4
English	A-	AP (+1)	4.7 (3.7 + 1)	5

Now, apply the formula:

GPA_{Letter-weighted} = ^{(4.5 × 3) + (2.3 × 3) + (3.0 × 4) + (4.7 × 5)} ⁄ _{(3 + 3 + 4 + 5)} =^55.9 ⁄ ₁₅ ≈ 3.72

Finally, translating 3.72 back to a letter grade, we get an A-.

2. Percentage Grade

A percentage grading system is a common method to assess student performance by measuring the percentage of correct answers, completed assignments, or overall performance relative to the total possible score. Here are typical percentage ranges and corresponding letter grades:

90 − 100% (A 4.0)
80 − 89% (B 3.0)
70 − 79% (C 2.0)
60 − 69% (D 1.0)

How to Calculate Percentage Grade GPA?
To calculate your percentage grade GPA, use the following formula:

GPA_Percentage = ^{(G1 × C1 + G2 × C2 + G3 × C3)} ⁄ _{(C1 + C2 + C3)}

Here,

G represents the percentage grade for each assignment or exam.
C represents the number of credits for each assignment or exam.

Steps to Calculate Percentage Grades GPA

Convert grades from percentages to decimals. (if they are not already in decimal form).
Multiply each grade by its corresponding credit.
Sum the results from step 2.
Sum the credits.
Divide the sum from step 3 by the sum from step 4.

Practical Example to Calculate Percentage Grades GPA

Assume you're finishing a course with the following grades:

Assessment	Percentage	Credits
Essay	93%	3
Midterm Exam	92%	4
Final Exam	87%	3

Now, apply the formula:

GPA_Percentage = ^{((93 / 100) × 3 + (92 / 100) × 4 + (87 / 100) × 3)} ⁄ _{( 3 + 4 + 3)} = ^9.08⁄_1.00= 9.08

So, the final grade is 90.8%, which corresponds to an A- in a letter grade.

How to Convert to GPA from Different Grading Systems?

In the US, most schools use a 4.0 GPA scale. Here's a typical letter & percentage grade to GPA conversion:

Letter Grade	Percentage Range	GPA 4.0 Scale
A+	97-100%	4.0
A	93-96%	4.0
A-	90-92%	3.7
B+	87-89%	3.3
B	83-86%	3.0
B-	80-82%	2.7
C+	77-79%	2.3
C	73-76%	2.0
C-	70-72%	1.7
D+	67-69%	1.3
D	63-66%	1.0
D-	60-62%	0.7
F	0-59%	0.0

Some schools award 4.3 for an A+, allowing for a GPA higher than 4.0. The percentages and scales may vary, so check your school's guidelines.

How to Calculate GPA?

To calculate the GPA, you would:

Convert each grade into its numerical equivalent.
Multiply each grade by the number of credits (or weight) of the course.
Sum these values.
Divide by the total number of credits (or weights).

So, to calculate your GPA, use this formula:

GPA = ^{(g1 × c1) + (g2 × c2) + (g3 × c3) + ...}⁄ _{(c1 + c2 + c3 + ...)}

Here,

Grades = g1, g2, g3…
Credits = c1, c2, c3...

Now, let’s explore more in the following section how different GPAs are being calculated:

High School GPA

GPA (Grade Point Average) is a key measure of academic performance used in most U.S. high schools, typically on a 4.0 scale.

Here’s how to calculate your high school GPA:

Unweighted GPA:

The formula to calculate the unweighted grades is:

GPA_unweighted = ^{∑ GPE}⁄ _{∑ Courses}

Example Unweighted High School GPA Calculation:

Course	Grade	Grade Point Equivalent(GPE)
Maths	A	4.0
Biology	C+	2.3
History	B	3.0
English	A-	3.7

Now, let’s add the values to the formula & calculate the GPA:

GPA_unweighted = ^{(4.0 + 2.3 + 3 + 3.7)} ⁄ ₄ =¹³⁄₄ = 3.25

2. Weighted GPA:

The formula to calculate the weighted grades is:

GPA_weighted = ^{∑ GPE}⁄_{∑ Courses}

Example Weighted High School GPA Calculation:

Course	Grade	Course Type	Weighted Grade Point Equivalent (WGPE)
Maths	A	Honors (+0.5)	4.5 (4.0+0.5)
Biology	C+	Regular	2.3
History	B	Regular	3.0
English	A-	AP(+1)	4.7 (3.7+1)

Now, let’s add the values to the formula & calculate the GPA:

GPA_weighted =^{(4.0 + 2.3 + 3 + 3.7)} ⁄ ₄ = ¹³⁄₄ = 3.25

College GPA

Similar to high school, most U.S. colleges also use a 4.0 GPA scale for GPA.

Here’s how to calculate your college GPA:

To calculate your GPA use the following formula:

GPA =^{∑ (grade value × credit points)} ⁄ _{∑ credit points}

This formula is the sum of weighted grades divided by total credit points.

Example Calculation:

Suppose you have the following courses and grades:

Course	Credits	Grade	Equivalent GPA Value
Maths	3	A	4
Physics	4	B+	3.3
Biology	4	C	2
Chemistry	4	B-	2.7

Now, let’s add the values to the formula & calculate the GPA:

GPA =^{(3 × 4.0) + (4 × 3.3) + (2 × 2.0) + (2 × 2.7)} ⁄ _{(3+ 4 + 2 + 2)} = ^34.6 ⁄ ₁₁ ≈ 3.15

Thus, your GPA is approximately 3.15.

Cumulative GPA

A cumulative GPA (Grade Point Average) includes all of the grade points earned across all terms and is weighted by the number of credits each course is worth. Here’s a detailed breakdown, including a practical example using the data from the image.

Formula for Calculating Cumulative GPA:

Cumulative GPA = ^{∑ (Current Quality Points) + (Previous GPA × Previous Credits)} ⁄ _{∑ (Current Credits) + Previous Credits}

Where:

G1, G2, and G3 are the grade points for the current courses.
C1, C2, C3 are the credits for the current courses.
Gp is the previous cumulative GPA.
Cp is the previous credits.

Practical Example of Calculation of Cumulative GPA (Letter):

Let’s use the following data and the upper formula to calculate the cumulative GPA practically:

Current Course	Letter Grade	Equivalent Grade Point	Credits
E120	A	4.0	3
IPE101	A-	3.7	4
ME101	B+	3.3	3

Previous Cumulative GPA: 3.5
Previous Credits: 20

Step-by-Step Calculation:

Calculate Quality Points:

a. E120: 4.0 × 3 = 12.0
b. IPE101: 3.7 × 4 = 14.8
c. ME101: 3.3 × 3 = 9.9
d. Previous: 3.5 × 20 = 70.0

The sum of Quality Points and Credits:

a. Total Quality Points = 12.0 + 14.8 + 9.9 + 70.0 = 106.7
b. Total Credits = 3 + 4 + 3 + 20 = 30

Calculate Cumulative GPA:

Cumulative Letter GPA = 106.7 / 30 ≈ 3.56

Thus, the cumulative GPA is approximately 3.56.

Practical Example of Calculation of Cumulative GPA (Percentage):

Let’s use the following data and the upper formula to calculate the cumulative GPA practically:

Current Course	Letter Grade	Equivalent Grade Point	Credits
E120	92%	4.0	3
IPE101	90%	3.7	4
ME101	89%	3.3	3

Previous Cumulative GPA: 3.5
Previous Credits: 20

By adding these values to the formula like before:

Cumulative Percentage GPA = ^{(4.0 × 3 + 3.7 × 4 + 3.3 × 3) + (3.5 × 20)} ⁄ _{(3 + 4 + 3 + 20)} = ^106.7 ⁄₃₀ ≈ 3.56

Thus, the cumulative GPA is approximately 3.56.
