Weighted vs Unweighted GPA: What's the Difference?
How weighted and unweighted GPA are calculated, which one colleges actually look at, and when each one matters for your applications.
Quick Answer
An unweighted GPA measures grades on a 4.0 scale regardless of course difficulty. A weighted GPA gives extra points for AP, IB, and honours courses, often reaching above 4.0. Most colleges recalculate both on their own scale during admissions review.
The short answer
An unweighted GPA uses a straight 4.0 scale and treats every course identically — an A is always a 4.0 whether you earned it in a regular English class or an Advanced Placement one. A weighted GPA rewards course difficulty by adding extra grade points for AP, IB, or honours classes, allowing the scale to go above 4.0. Both numbers can appear on the same transcript, and both are used differently depending on context.
Important context: Not all high schools offer weighted GPA, and those that do use different scales. The information below describes the most common U.S. high school conventions. College and graduate school GPAs are almost always unweighted 4.0-scale GPAs as reported on the official transcript. Always verify the grading policy of your institution.
What is unweighted GPA?
An unweighted GPA is calculated on a fixed 4.0 scale where each letter grade has the same point value regardless of the course level. The scale is straightforward:
| Letter Grade | Percentage Range | Unweighted Grade Points |
|---|---|---|
| A / A+ | 90–100% | 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 |
| D | 60–69% | 1.0 |
| F | Below 60% | 0.0 |
How unweighted GPA is calculated
To calculate your unweighted GPA, assign each grade its grade point value, multiply it by the number of credit hours the course carries, add all those products together, then divide by the total number of credit hours attempted. For example: an A (4.0) in a 3-credit course contributes 12.0 quality points. A B (3.0) in a 3-credit course contributes 9.0 quality points. Total 21.0 quality points ÷ 6 credit hours = 3.5 unweighted GPA.

What is weighted GPA?
A weighted GPA uses a scale that exceeds 4.0 for advanced courses. The most common weighted scales give additional grade points to AP and IB courses (typically +1.0) and to honours courses (typically +0.5). A student who earns an A in an AP course receives 5.0 grade points rather than the standard 4.0 — reflecting both the grade and the course difficulty.
How AP, IB, and honours courses affect weighted GPA
The bonus applies only when the grade is passing. Earning a D or F in an AP course does not earn a 5.0 — it earns 2.0 or 0.0, same as any other course at that grade. Here is how the most common weighted scale works across course types:
| Letter Grade | Regular Course | Honours Course (+0.5) | AP / IB Course (+1.0) |
|---|---|---|---|
| A | 4.0 | 4.5 | 5.0 |
| B | 3.0 | 3.5 | 4.0 |
| C | 2.0 | 2.5 | 3.0 |
| D | 1.0 | 1.5 | 2.0 |
| F | 0.0 | 0.0 | 0.0 |
How weighted GPA is calculated — step by step
- List all courses with their grade, credit hours, and course type (regular, honours, AP/IB).
- Assign weighted grade points using the scale above — AP A = 5.0, honours A = 4.5, regular A = 4.0.
- Multiply each course's weighted grade point by its credit hours to get quality points.
- Sum all quality points, then sum all credit hours.
- Divide total quality points by total credit hours. The result is your weighted GPA.

Can your weighted GPA exceed 4.0?
Yes — and this is one of the most common points of confusion. Because AP and IB courses assign up to 5.0 for an A, a student who earns strong grades in those courses will have a weighted GPA above 4.0. This is intentional: the scale is designed to reward both high grades and rigorous course selection simultaneously.
The theoretical maximum on a standard weighted scale (AP/IB +1.0, honours +0.5) is 5.0 — achieved only by earning an A in every AP or IB course with no regular or honours classes. In practice, most students take a mix of course types, so weighted GPAs above 4.5 are uncommon but not rare among students who pursue a heavy AP schedule with high grades.
A weighted GPA above 4.0 does not mean a student has "more than perfect" grades in any absolute sense — it means they combined solid grades with demanding coursework. A 4.8 weighted GPA with all APs is a very different academic record from a 4.8 weighted GPA with a mix of honours and a few regular courses.

Which GPA do colleges look at for admissions?
The honest answer is: most colleges look at both — and neither one exclusively. U.S. colleges receive the full high school transcript alongside the GPA, so admissions officers can see the courses you took, the grades you earned, and any grade trends. Many selective institutions recalculate GPA on their own internal scale to make fair comparisons across thousands of applicants from different school districts with different grading policies.
How colleges use each GPA type
In practice, the unweighted GPA is often the more standardised figure because it does not vary by school policy — every school's A earns a 4.0. The weighted GPA is used as a signal of course rigor but cannot be compared directly across schools because weighting policies differ. A 4.7 weighted GPA from one school district may reflect very different course choices than a 4.7 from another.
Some colleges publish their average admitted GPA as an unweighted figure; others publish both. Always check the current class profile and admissions requirements for each institution rather than relying on general benchmarks.
To explore how your current GPA compares to typical ranges for admission, see the GPA Scale Explained guide for a breakdown of how grades and grade points work across systems.
Which GPA do grad schools use?
Graduate schools in the United States evaluate your undergraduate college GPA — not your high school GPA. Your college transcript reports a cumulative GPA on a 4.0 scale, and that is what graduate programs use. High school weighted GPA is irrelevant at this stage.
Graduate programs have their own minimum GPA thresholds and entering-class averages, which vary by program type and institution. A master's program might publish a minimum of 3.0, while a competitive PhD or professional program may have entering classes with GPAs well above that figure. Check each program's current requirements and class profile rather than relying on general rules.
Which GPA to report on college applications and resumes
College applications
For high school students applying to college: report the GPA that appears on your official high school transcript. If your school provides both weighted and unweighted, the Common App and most applications will ask for the GPA as it appears on your transcript. Do not inflate or convert your GPA to a different scale for the application — colleges verify against the transcript.
Job resumes
For college students or graduates applying for jobs: use your cumulative college GPA as it appears on your college transcript — this is an unweighted 4.0-scale GPA. Do not use your high school weighted GPA on a professional resume. As a general guideline, only include GPA on a resume if it is strong enough to help your application — many career advisors suggest including it if it is 3.5 or above, and omitting it once you have substantial work experience.
How to convert between weighted and unweighted GPA
If you need to approximate your unweighted GPA from a weighted one, you can work backwards by removing the bonus points added for each advanced course. For each AP or IB course, subtract 1.0 from that course's grade point before recalculating. For each honours course, subtract 0.5. Then recalculate the GPA using the standard formula.
Keep in mind this is an approximation — the exact result depends on your school's specific weighting policy, the number of credit hours per course, and whether your school uses plus/minus grades. For an accurate conversion, use the GPA Calculator and enter your courses with the standard 4.0 grade points for each grade.
Quick note on GPA scales: Some schools use a 4.3 scale (where an A+ = 4.3), a 5.0 scale, or other variations. Always check your school's official grading policy before comparing or converting your GPA to another system.
Frequently asked questions
Is a 4.5 weighted GPA good?
A 4.5 weighted GPA is generally very strong and indicates a combination of high grades and a rigorous course load — typically multiple AP or IB classes. Its competitiveness depends on your school's scale, your class rank, and the specific programs you are applying to. In context of your school and transcript, it is usually a positive signal.
Does a weighted GPA hurt college applications?
No — a high weighted GPA combined with rigorous courses is generally positive. The concern arises only if a student inflates their course list beyond their abilities and earns poor grades. A 4.2 weighted GPA earned with genuine effort in difficult courses is more compelling than a 4.0 unweighted GPA with all regular classes, all else being equal.
What if my school doesn't offer AP or IB courses?
Colleges understand that course availability varies by school. If your school does not offer AP or IB courses, admissions reviewers typically evaluate your record in the context of what was available to you. Taking the most rigorous courses your school offers — even if they are not weighted — is what matters.
Do all colleges recalculate GPA?
Not all colleges recalculate GPA, but many selective institutions do — particularly to standardise comparisons across different high schools and districts. Some colleges publish their own recalculation policy; others do not. When in doubt, the full transcript is what matters most.
What is the difference between weighted and unweighted GPA?
An unweighted GPA uses a standard 4.0 scale and treats all courses equally — an A is a 4.0 regardless of whether it is in a regular or advanced class. A weighted GPA gives additional grade points for more demanding courses such as AP, IB, or honours classes, allowing the scale to exceed 4.0. Both measure academic performance but reflect different aspects of a student's record.
Which GPA do colleges look at — weighted or unweighted?
Most U.S. colleges consider both, but many recalculate GPA on their own scale during the admissions review. Colleges typically review the full transcript alongside GPA, so the courses taken and grade trends matter as much as the single number. Always check each institution's published admissions information.
Can a weighted GPA be higher than 4.0?
Yes. On a common weighted scale, AP and IB courses assign up to 5.0 for an A, and honours courses assign up to 4.5 for an A. A student who earns strong grades in those courses can have a weighted GPA above 4.0 — sometimes reaching 4.5 or higher. The maximum depends on the scale your school uses.
How is a weighted GPA calculated for AP courses?
On a common weighted scale, an A in an AP course earns 5.0 grade points instead of the standard 4.0, a B earns 4.0 instead of 3.0, and a C earns 3.0 instead of 2.0. The weighted GPA is then computed the same way as an unweighted GPA: multiply each course's grade points by its credit hours, sum the totals, and divide by total credit hours.
How do AP, IB, and honours courses affect weighted GPA?
AP and IB courses typically receive a 1.0 bonus on the grade point (so an A becomes 5.0 instead of 4.0), while honours courses often receive a 0.5 bonus (so an A becomes 4.5). The bonus only applies if you earn a passing grade — a D or F in an AP course does not become a strong grade just because of the weight. Policies vary by school district.
What GPA do grad schools use — weighted or unweighted?
Graduate schools in the U.S. generally evaluate undergraduate GPA, which is typically an unweighted cumulative GPA on a 4.0 scale as reported on the college transcript. High school weighted GPA is not relevant for graduate admissions. Requirements vary by program, so check each program's current official criteria.
Which GPA should I put on my resume — weighted or unweighted?
For college applications, report whichever GPA your school officially provides on your transcript — usually your school's own weighted or unweighted GPA. For job applications, report your cumulative college GPA as shown on your official transcript, which is typically an unweighted 4.0-scale GPA. Only include GPA if it is strong enough to help rather than hurt your application.
How do I convert my weighted GPA to unweighted?
To approximate your unweighted GPA from a weighted one, subtract the bonus points added for advanced courses and recalculate using the standard 4.0 scale for all grades. For AP courses, subtract 1.0 from the grade point; for honours courses, subtract 0.5. Then recalculate your GPA using those adjusted values. Use a GPA calculator or converter for an accurate result.
