Weighted GPA calculator
This weighted GPA calculator computes both your weighted and unweighted grade point averages from the same course list. Select Regular, Honors, AP, or IB for each course, then enter credit hours and letter grade. The tool instantly shows weighted GPA on the 5.0 scale and unweighted GPA on the 4.0 scale side by side.
Weighted GPA
AP/IB +1.0 · Honors +0.5
Unweighted GPA
Standard 4.0 scale · No bonuses

What Is a Weighted GPA Calculator?
A weighted GPA calculator computes grade point average using a scale above 4.0 by awarding bonus grade points for advanced courses such as AP, IB, and honors, reflecting course difficulty alongside letter grades.
- Adds 0.5–1.0 bonus grade points for honors, AP, and IB courses
- Supports a 5.0 maximum scale for AP-level courses
- Calculates both weighted and unweighted GPA from the same course list
- Distinguishes regular, honors, and AP course tiers for accurate weighting
- Helps students understand how advanced coursework boosts GPA
Weighted GPA was designed to reward students who take more rigorous courses by awarding extra grade points for advanced coursework. The College Board notes that AP courses are weighted differently by each high school, with most granting 1.0 additional point for an A in an AP course on a 5.0 scale. Many colleges recalculate applicant GPAs using their own unweighted scale during admissions review.
How Do You Calculate a Weighted GPA?
Identify course tier for each class
Categorize each course as Regular (no bonus), Honors (+0.5), or AP/IB (+1.0) based on your school's policy.
Assign the weighted grade point value
Add the tier bonus to the base grade point value: an A in AP = 4.0+1.0 = 5.0; a B in Honors = 3.0+0.5 = 3.5.
Multiply by credit units
Multiply the weighted grade point by the course credit hours to get weighted quality points.
Sum weighted quality points and credits
Add all weighted quality points together. Add all credit units together.
Divide for weighted GPA
Divide total weighted quality points by total credit units. The result is the weighted GPA on the 5.0 scale.
Worked Example
AP Calc A (5.0×1cr), Honors English A- (4.2×1cr), Regular History B (3.0×1cr). Total: 12.2 ÷ 3 = 4.07 weighted GPA.
Weighted GPA Scale by Course Type
| Letter Grade | Regular (4.0 scale) | Honors (+0.5) | AP / IB (+1.0) |
|---|---|---|---|
| A (4.0) | 4.0 | 4.5 | 5.0 |
| A- (3.7) | 3.7 | 4.2 | 4.7 |
| B+ (3.3) | 3.3 | 3.8 | 4.3 |
| B (3.0) | 3.0 | 3.5 | 4.0 |
| B- (2.7) | 2.7 | 3.2 | 3.7 |
| C (2.0) | 2.0 | 2.5 | 3.0 |
Weighted GPA calculator - Weighted GPA Explained
A weighted GPA rewards students who take more rigorous courses by adding extra grade points for Honors, AP (Advanced Placement), and IB (International Baccalaureate) classes. Instead of the standard 4.0 maximum, weighted GPAs can exceed 4.0 - most commonly reaching a 5.0 ceiling for AP/IB courses.
The goal of weighting is to reflect that earning a B in AP Calculus represents a higher level of academic achievement than earning a B in a standard math course.
Weighted Grade Point Scale
| Grade | Regular | Honors (+0.5) | AP / IB (+1.0) |
|---|---|---|---|
| A | 4.0 | 4.5 | 5.0 |
| A− | 3.7 | 4.2 | 4.7 |
| B+ | 3.3 | 3.8 | 4.3 |
| B | 3.0 | 3.5 | 4.0 |
| B− | 2.7 | 3.2 | 3.7 |
| C+ | 2.3 | 2.8 | 3.3 |
| C | 2.0 | 2.5 | 3.0 |
| D | 1.0 | 1.5 | 2.0 |
| F | 0.0 | 0.0 | 0.0 |
AP/IB weighting per College Board and IBO standards. Exact bonus values vary by school district.
How Colleges View Weighted GPA
Important: Most colleges recalculate GPA on their own scale when reviewing applications. Many top universities standardize to an unweighted 4.0 scale to compare applicants from different schools fairly.
Even when recalculated, course rigor remains visible on the transcript. Admissions officers see the AP/IB courses taken, which signals intellectual preparation regardless of GPA weighting.
Unweighted GPA Conversion
To convert a weighted GPA to an unweighted equivalent, substitute standard (unweighted) grade point values and recalculate using the same formula:
Weighted GPA Context and Benchmarks
| Purpose | Minimum GPA | Notes |
|---|---|---|
| UC System Honors Cap | N/A | The University of California caps honors bonus points at 8 semesters of approved Honors/AP/IB courses. |
| AP Course Bonus (standard) | +1.0 per grade | College Board defines AP courses as adding 1.0 to the grade point value (A in AP = 5.0, B in AP = 4.0). |
| Honors Course Bonus (standard) | +0.5 per grade | Honors courses typically add 0.5 to the grade point (A in Honors = 4.5). Exact bonus varies by school. |
| IB Diploma Bonus | +1.0 per grade | IB Higher Level and Standard Level courses receive the same weighting as AP courses at most US high schools. |
| College Admission Recalculation | Unweighted 4.0 | Most selective colleges recalculate all applicants on an unweighted 4.0 scale for equal comparison. |
Common Mistakes When Calculating Weighted GPA
Applying weighted GPA values when colleges request unweighted
Problem: Submitting a 4.4 weighted GPA on an application that asks specifically for unweighted GPA on a 4.0 scale overstates academic performance.
Fix: Calculate both versions. Use this calculator with standard (unweighted) grade point values for the unweighted GPA, and apply Honors/AP bonuses for the weighted version.
Using the wrong bonus amount for Honors vs. AP courses
Problem: Some schools add 0.5 for both Honors and AP. Others add 0.5 for Honors and 1.0 for AP. Applying the wrong bonus produces an incorrect GPA.
Fix: Confirm the school's specific weighting policy. Consult the course catalog or registrar. Enter the exact credit and grade point values this calculator accepts.
Counting an F in an AP course as 0.0 on unweighted scale but expecting bonus
Problem: Students assume the AP designation adds value to a failing grade. An F earns 0.0 points on both weighted and unweighted scales.
Fix: An F in any course - regular, Honors, or AP - earns 0.0 grade points. The bonus only applies to passing grades (D and above at most schools).
Not checking whether the GPA calculator applies weighting automatically
Problem: Using a basic GPA calculator that does not account for course level overstates or understates the weighted GPA.
Fix: This calculator accepts the actual grade point value per course. Enter 5.0 for an A in AP, 4.5 for an A in Honors, or 4.0 for an A in regular courses.
