Weighted vs unweighted GPA
An unweighted GPA treats every class the same: an A is a 4.0 whether it came from AP Chemistry or from PE. A weighted GPA adds extra points for harder classes, so it can go above 4.0. The usual extras are 0.5 for an honors class and 1.0 for an AP or IB class, which makes an A in AP worth 5.0. Many schools report both, and this calculator shows both from the same list of classes.
weighted GPA = sum of ((grade points + level bonus) × credits) ÷ sum of credits
A worked example
Six year-long classes, one credit each, on the plus/minus scale:
| Class | Level | Grade | Unweighted | Weighted |
|---|---|---|---|---|
| US History | AP | A | 4.0 | 4.0 + 1.0 = 5.0 |
| English 11 | Honors | B+ | 3.3 | 3.3 + 0.5 = 3.8 |
| Algebra II | Regular | A- | 3.7 | 3.7 |
| Chemistry | Regular | B | 3.0 | 3.0 |
| Spanish IV | AP | B | 3.0 | 3.0 + 1.0 = 4.0 |
| PE | Regular | A | 4.0 | 4.0 |
Unweighted: 4.0 + 3.3 + 3.7 + 3.0 + 3.0 + 4.0 = 21.0, and 21.0 ÷ 6 = 3.50. Weighted: 5.0 + 3.8 + 3.7 + 3.0 + 4.0 + 4.0 = 23.5, and 23.5 ÷ 6 = 3.9167, which rounds to 3.92.
If one of those classes were a semester class worth 0.5 credit, it would count half as much as the others. Enter its credits as 0.5 and the calculator weights it that way.
Rules that differ by school
- How much the extra is. 0.5 and 1.0 are common, but some schools give honors a full point, give dual-enrollment college classes the AP weight, or use no weighting at all. Change the two numbers under Weighting to match your handbook.
- Which grades get it. An F never gets extra weight here. Some schools also hold it back from grades below a C. Choose “Only a C or better” if yours does.
- Plus and minus. Some high schools count an A- as 3.7; others count every A as 4.0. Pick “Letters only” for the second, or edit the points for any letter.
- Which classes count. Some schools leave PE, electives or pass/fail classes out of the GPA. Leave those classes off the list.
To include earlier years, add their classes as more rows (up to 40). If you already know your cumulative GPA and want a target, the raise GPA calculator works out what you need next semester.
What colleges see
Your transcript shows the GPA your school calculates, and your counselor usually sends a school profile that explains its scale and which classes are honors or AP. Many colleges then recalculate a GPA of their own from your transcript, often using only core academic classes. That is why the weighted number here is a guide to your school’s figure, not to every college’s. Once you are in college, the college GPA calculator handles credit hours and 4.3 scales.
Percent grades
If your report card shows percentages, convert them to letters with your school’s cutoffs first. Many schools use 90 for an A, 80 for a B, 70 for a C and 60 for a D, but others use stricter cutoffs such as 93 for an A. Your handbook or the syllabus has the right ones.
High school GPA FAQ
What is the difference between a weighted and an unweighted GPA?
An unweighted GPA counts every class on the same 4.0 scale. A weighted GPA adds extra points for honors, AP and IB classes, usually 0.5 and 1.0, so it can be higher than 4.0.
How much do honors and AP classes add to a GPA?
Commonly 0.5 for honors and 1.0 for AP or IB, so an A in an AP class counts as 5.0. Schools differ, and some do not weight at all. Edit the two numbers under Weighting to match your school.
Can a weighted GPA be higher than 4.0?
Yes. With AP worth an extra 1.0, straight A’s in AP classes give a 5.0. An unweighted GPA cannot go above the top of the scale, which is 4.0 for most schools.
Does an F in an AP class get the extra point?
Not in this calculator: an F stays at 0 whatever the level. Some schools also give no extra weight below a C; choose “Only a C or better” if yours does.
Do semester classes count less than year-long classes?
If your school gives 0.5 credit per semester, yes. Enter 0.5 for a semester class and 1 for a year-long class, and the year-long class counts twice as much.
Which GPA do colleges use?
Colleges see the GPA on your transcript along with your school’s profile, and many recalculate their own from your classes, often counting core academic classes only. Neither number here is the one every college uses.
Does this calculator send my grades anywhere?
No. The math runs in your browser. The classes and grades you type are not sent to any server and are not saved, so reloading the page clears them.
