How to use the weighted GPA calculator
Use this weighted GPA calculator when your transcript includes advanced classes, you want to check how their extra points affect your GPA, or you are comparing possible grades for next term. You will see both GPAs from the same courses, so you can compare them without calculating twice.
- Enter each class. Select its Grade, Credits and Level. Course names are optional. Use Regular, Honors, AP, IB or Dual Enroll. as appropriate.
- Match your school’s rules. The default scale uses A = 4.0, Honors +0.5 and AP/IB/Dual Enrollment +1.0. Open Options for another base grade scale. Check the bonus rules below before treating the result as your transcript GPA.
- Add your history and read the result. Use + Add class or + Add year. The main result is weighted GPA; unweighted GPA is shown alongside it. Try sample grades loads a complete example.
Tip
If all classes count equally at your school, use the same credit value for each. If a full-year class earns 1 credit and a semester class earns 0.5, enter those values so the longer class counts twice as much.
Under Options → Add previous GPA, enter a prior weighted GPA and the credits behind it to extend your weighted cumulative total. Do not enter an unweighted prior GPA into a weighted history, and do not enter the same courses again.
Weighted GPA scale: Honors, AP and IB
Weighted GPA adds extra grade points for eligible advanced classes before averaging. Under this calculator’s default rules, an A is worth 4.0 in Regular, 4.5 in Honors and 5.0 in AP, IB or Dual Enrollment.
| Grade | Regular | Honors (+0.5) | AP / IB / Dual (+1.0) |
|---|---|---|---|
| A / 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 |
| C− | 1.7 | 2.2 | 2.7 |
| D+ | 1.3 | 1.8 | 2.3 |
| D | 1.0 | 1.5 | 2.0 |
| D− | 0.7 | 1.2 | 1.7 |
| F | 0.0 | 0.0 | 0.0 |
Check your school’s policy
Schools differ in their bonus amounts, eligible courses and minimum grades for extra points. This tool’s default boosts include D grades; some schools award bonuses only for C or better. Changing the base scale does not automatically apply a school’s honors caps or eligibility rules.
How to calculate weighted GPA
Convert the letter grade to points, add the eligible course-level bonus, then multiply by credits. Add those quality points and divide by the credits included in your GPA.
Formula
Weighted GPA = Σ[(base grade points + eligible bonus) × course credits] ÷ Σ course credits
Σ means “add them all.” Quality points are the points for a course multiplied by its credits.
Example: the same grades, two GPAs
These four one-credit classes use the same grades as Try sample grades. Regular classes receive no bonus; Honors adds 0.5 and AP adds 1.0.
| Course | Grade | Level | Weighted points | Credits | Quality points | |||
|---|---|---|---|---|---|---|---|---|
| AP Biology | A– | AP +1 | 4.7 | 1 | 4.7 | |||
| Honors English 11 | B+ | Honors +0.5 | 3.8 | 1 | 3.8 | |||
| Algebra II | B | Regular | 3.0 | 1 | 3.0 | |||
| Spanish 3 | A | Regular | 4.0 | 1 | 4.0 | |||
Total quality points 15.5 Credits counted 4 Weighted GPA 3.88 Unweighted GPA, same grades without the level boost: 14.0 ÷ 4 = 3.50 | ||||||||
Unweighted points: 3.7 + 3.3 + 3.0 + 4.0 = 14.0. Weighted points: 4.7 + 3.8 + 3.0 + 4.0 = 15.5. Divide each total by four credits: 3.50 unweighted and 3.875, displayed as 3.88 weighted.
Different credits?
If AP Biology were worth 0.5 credit instead of 1, its weighted contribution would be 4.7 × 0.5 = 2.35. The total would be 13.15 points over 3.5 credits, giving a weighted GPA of 3.76.
Weighted vs. unweighted GPA
| Question | Unweighted GPA | Weighted GPA |
|---|---|---|
| What changes the points? | Letter grade | Letter grade plus eligible course-level bonus |
| A in Regular / AP | 4.0 / 4.0 | 4.0 / 5.0 under this tool’s defaults |
| Result for the example | 3.50 | 3.88 |
| Can it exceed 4.0? | Not on a standard 4.0 base scale | Yes, when advanced-course bonuses raise the average |
Course difficulty and credits are two separate kinds of weighting. Honors/AP bonuses raise a course’s grade-point value; credits determine how much that course affects the average. A college GPA may be credit-weighted without including any Honors or AP bonus.
What is a good weighted GPA?
A weighted GPA is useful only with its scale and course rules attached. A 4.2 on one school’s system may represent a different grade mix from a 4.2 at another school. Check your unweighted GPA alongside it to understand your actual letter-grade average.
| Default-scale result | What it tells you | What to check |
|---|---|---|
| Above 4.0 | Advanced-course bonuses lift the average above the standard unweighted maximum | Your unweighted GPA and which classes receive bonuses |
| Exactly 4.0 | Could reflect all A’s in Regular classes or a different mix with advanced classes | The underlying grades and course levels |
| Below 4.0 | Your grades and bonuses combine to this average | Which individual grades you can improve |
For perspective, five equal-credit classes with three AP A’s and two Regular A’s produce (5 + 5 + 5 + 4 + 4) ÷ 5 = 4.60 weighted and 4.00 unweighted. A 5.0 average would require every included grade to earn 5.0 under these rules.
Which GPA should you report to colleges?
Report the GPA and scale requested by the application, using your official transcript when instructed. Colleges may recalculate GPA using their own eligible subjects, year ranges and honors limits, so a general weighted GPA is not automatically a college’s admissions GPA.
Quote
“UC has a specific way to calculate the grade point average (GPA) it requires for admission.”
UC Admissions, GPA requirement
UC’s calculation uses a defined course window, ignores plus/minus grades and limits honors points. This calculator does not automatically apply those restrictions. Read the official UC GPA instructions if you are applying to a UC campus.
Plan your next step
Try a realistic grade change above and compare the result. If you need a specific cumulative GPA, use the Target GPA Calculator to check the required future average. Extra course credits help only if your new grades support the goal.
Frequently asked questions
How do I calculate weighted GPA?
Add the eligible Honors, AP or IB bonus to each course’s base grade points, multiply by its credits, then divide the total quality points by the total GPA-counted credits. Use your school’s bonus rules for an official match.
Can my weighted GPA be higher than 4.0?
Yes. Under the default scale, an AP A earns 5.0 points and an Honors A earns 4.5. Those bonuses can make the weighted average exceed 4.0.
Is an A in Honors worth 4.5 or 5.0?
This calculator uses 4.5 for an Honors A and 5.0 for an AP, IB or Dual Enrollment A. Your school may use different bonus values, so check its grading policy.
Do AP exam scores affect this GPA?
Enter the letter grade earned in the AP course, not the AP exam score from 1 to 5. The course grade and exam score are different records.
Does an F in an AP class earn a bonus?
No. In this calculator an F is 0.0 points at every course level, and its credits count when the F is included in GPA. Follow your school’s rules for other low grades.
Can I convert weighted GPA to unweighted GPA by subtracting 1?
No. Your courses may have different bonuses and credits, so subtracting a fixed number is inaccurate. Recalculate from the original course grades without their bonuses.
Is this the same as UC capped weighted GPA?
No. UC uses specific courses, years and honors-point limits. A general weighted GPA does not automatically follow those admissions rules.
What if my result differs from my transcript?
Check bonus eligibility, credits, plus/minus values, repeated courses and rounding. Your transcript is the official record; this calculator is a planning and self-check tool.
