How to calculate unweighted GPA
Understanding How to calculate unweighted GPA is essential for every student. Your Grade Point Average (GPA) is calculated by dividing total grade points earned by total credit hours attempted. Use our free calculator below to compute your GPA instantly, or read our step-by-step guide.

What Is the Method for Calculating Unweighted GPA?
Calculating unweighted GPA means applying the standard 4.0 scale to every course regardless of difficulty level, so AP and honors courses receive the same grade point values as regular courses in the average.
- Uses the 4.0 maximum scale with no bonus for AP, honors, or IB courses
- All courses at the same letter grade contribute equal grade point value
- The most widely reported GPA for college applications and transcripts
- Calculated using the standard quality-points formula divided by credit units
- Allows fair academic comparison across students in different course tracks
Unweighted GPA reflects raw academic performance without adjusting for course rigor. While a weighted GPA may better reflect the difficulty of a student's schedule, the unweighted GPA provides a clean, comparable measure that most US colleges use as the baseline for admissions evaluation. Students taking challenging courses will have a lower unweighted GPA than their weighted GPA reflects, which is why course rigor is evaluated alongside the GPA in selective admissions.
How to Calculate Unweighted GPA?
List all courses without course-type labels
Treat every course - regular, honors, AP, IB - identically. No tier labels needed for unweighted calculation.
Apply the standard 4.0 grade point values
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=1.0, F=0.0. No bonus additions.
Multiply grade points by credit units
Compute quality points using the base grade point values only, without adding any honors or AP bonus.
Sum quality points and credit units
Total all quality points. Total all credit units.
Divide for unweighted GPA
Divide total quality points by total credit units. The result cannot exceed 4.0.
Worked Example
AP Calc A (4.0×1), Honors English A- (3.7×1), Regular Bio B+ (3.3×1). Unweighted = 11.0 ÷ 3 = 3.67. No bonus added.
Unweighted GPA Grade Point Values (4.0 Scale)
| Letter Grade | Unweighted Points | Note |
|---|---|---|
| A+ / A | 4.0 | Maximum on unweighted scale - applies to ALL course types |
| A- | 3.7 | Same value for Regular, Honors, AP, and IB courses |
| B+ | 3.3 | No bonus for AP/honors course difficulty |
| B | 3.0 | Same value regardless of course rigor |
| B- | 2.7 | Unweighted scale treats course difficulty as equal |
| C | 2.0 | Performance in AP C still earns only 2.0 on unweighted scale |
| F | 0.0 | Failing grade has no credit-hour contribution to GPA |
How to calculate unweighted GPA - Step-by-Step Guide
Calculating GPA follows the same straightforward formula used by every high school and college in the United States. Two pieces of information are required for each course: the letter grade (converted to grade points) and the credit hours assigned to that course.
The GPA Formula
GPA = Σ(Grade Points × Credit Hours) ÷ Σ(Credit Hours)
Where Σ means "sum of all courses"
Step-by-Step Calculation
List all courses
Write down each course, its credit hours, and the final letter grade.
Convert grades to grade points
Use the standard 4.0 scale to convert each letter grade to a number.
Multiply grade points by credit hours
For each course, multiply the grade point value by credit hours to get quality points.
Sum quality points and credit hours
Add all quality points and all credit hours separately.
Divide to get GPA
Divide total quality points by total credit hours.
Grade Point Reference
| Grade | GPA Points | Percentage | Description |
|---|---|---|---|
| A+ | 4.0 | 97–100% | Exceptional |
| A | 4.0 | 93–96% | Excellent |
| A− | 3.7 | 90–92% | Near Excellent |
| B+ | 3.3 | 87–89% | Above Average |
| B | 3.0 | 83–86% | Average |
| B− | 2.7 | 80–82% | Below Average |
| C+ | 2.3 | 77–79% | Satisfactory |
| C | 2.0 | 73–76% | Passing |
| C− | 1.7 | 70–72% | Near Passing |
| D+ | 1.3 | 67–69% | Below Passing |
| D | 1.0 | 63–66% | Minimal Pass |
| D− | 0.7 | 60–62% | Poor |
| F | 0.0 | 0–59% | Failing |
Grade point values per the standard US grading scale. Some institutions use A+ = 4.3 or omit plus/minus grades.
GPA Scale Variations by Institution Type
| Purpose | Minimum GPA | Notes |
|---|---|---|
| Standard US Scale | 0.0 – 4.0 | Most US high schools and colleges. A = 4.0, F = 0.0. Plus/minus grades use intermediate values. |
| 4.3 Scale (A+ = 4.3) | 0.0 – 4.3 | Some schools award 4.3 for A+. The denominator in the GPA formula stays the same; only the A+ value changes. |
| Weighted Scale (AP/IB) | 0.0 – 5.0 | AP courses add +1.0, Honors add +0.5 to base grade point values. The scale exceeds 4.0. |
| Pass/Fail Courses | Excluded | P/F courses earn no grade points and are excluded from all GPA calculations. |
| Incomplete (I) Grade | Excluded | Incompletes are temporarily excluded from GPA. The grade converts once coursework is submitted. |
Common Mistakes When Calculating GPA
Calculating a simple average instead of credit-weighted average
Problem: Adding all letter grade point values and dividing by the number of courses treats a 1-credit PE class the same as a 4-credit Chemistry course.
Fix: Multiply each grade point by the course's credit hours first. Divide the sum of quality points by the sum of credit hours - not by the number of courses.
Using wrong point values for plus/minus grades
Problem: Assigning 3.0 to a B+ or 4.0 to an A− produces an inaccurate GPA. Plus/minus grades have specific intermediate values.
Fix: Use: A+ = 4.0, 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, D− = 0.7, F = 0.0.
Including P/F courses in the GPA calculation
Problem: Pass/Fail courses do not carry grade points. Adding them to the numerator or denominator distorts the GPA.
Fix: Exclude P/F courses from the GPA formula entirely. They count toward total credits attempted for financial aid but not for GPA.
Using the wrong scale (4.0 vs. 4.3)
Problem: Calculating on a 4.3 scale when the school uses 4.0 (or vice versa) makes A+ worth 4.3 when it should be 4.0.
Fix: Confirm the institution's specific grading scale before calculating. Most US schools cap at 4.0 even for A+.
