Weighted vs Unweighted GPA
Two ways of summarising your grades — one rewards course difficulty, the other does not. Here is how to tell which is which.
What the two GPAs actually measure
An unweighted GPA treats every course the same. An A is worth 4.0 grade points whether it came from a Regular English class, an Honors chemistry class, or an AP calculus class. A weighted GPA adds bonus points to the harder courses. The most common US convention adds 0.5 for Honors and 1.0 for AP or IB, so an A in AP calculus is worth 5.0, an A in Honors English is worth 4.5, and an A in a regular elective stays at 4.0.
The two numbers serve different purposes. Unweighted GPA gives a clean comparison of raw performance across students. Weighted GPA rewards taking on harder coursework, which can be more representative of academic effort. Many transcripts show both, and most colleges look at both alongside the courses you actually took.
How Regular, Honors, AP, IB, and college courses are usually weighted
The exact bonus depends on your school. The table below shows the most common convention in US high schools, but you should always confirm with your school's policy because some districts use different bonuses (for example +1.0 for Honors), restrict weighting to certain subjects, or only weight courses that appear on an approved list.
| Course type | Notes |
|---|---|
| Regular | Standard 4.0 scale, no bonus |
| Honors | +0.5 bonus is common (some schools use +1.0) |
| AP / IB | +1.0 bonus is common, capping an A at 5.0 |
| Dual-enrollment / College | Varies — sometimes treated as AP, sometimes Honors, sometimes Regular |
A useful sanity check: if your school's policy talks about a weighted maximum higher than 4.0 — for example 4.5 or 5.0 — your weighted GPA is using bonuses. If the maximum is 4.0, your school is reporting an unweighted GPA even if the underlying transcript mixes Regular and AP courses.
When each version matters
Class rank and honors lists at your school are usually based on the weighted GPA. College admissions, on the other hand, often recalculate using their own scale — some only count core academic subjects, some drop the weighting entirely, some apply a different bonus. That is why students from different schools can present very different GPAs and still be compared fairly.
When you are setting personal goals, decide which version you care about. If you want to track raw performance, use unweighted GPA. If you want to capture the difficulty of your schedule too, use weighted. Many students track both side by side so they can see whether a tough term still moved their underlying performance forward.
FAQ
- Which GPA do colleges care about more?
- Most US colleges look at both, then often recalculate using their own scale and the courses you took. The grades themselves and the rigor of your schedule typically matter more than which number you quote.
- Can my weighted GPA be higher than 4.0?
- Yes, on the common scale a weighted GPA can reach 5.0 with all AP or IB A grades. Schools with different conventions may use different maximums.
- Are middle school grades weighted?
- Usually middle school courses do not appear on the high school GPA, so weighting does not apply. Some districts make exceptions for high-school-level courses taken in middle school.
- What if my school does not weight at all?
- Then your unweighted GPA is your official GPA. Colleges will still see the AP and IB designations on your transcript even without a numeric bonus.
