GPA Calculator
Enter the letter grade and credits for each class to find your GPA on the standard 4.0 scale. Turn on the weighted option to add the Honors and AP/IB bonus some high schools use, and add your previous GPA to see your new cumulative GPA. A table shows the grade points and quality points behind every course.

How to use the GPA calculator
- Pick a grade for each course. Rows left on “—” are ignored. Up to 10 courses fit.
- Enter the credits. Use the credit hours from your transcript or course catalog. If every class counts the same, enter 1 for each.
- Choose what an A+ is worth. Some schools count it as 4.0, others as 4.3.
- Weighted GPA (optional): check the box and set each course to Regular, Honors or AP/IB. You then see both the weighted and the unweighted GPA.
- Cumulative GPA (optional, under Advanced options): enter your GPA so far and the credits it covers.
How your GPA is calculated
Each letter grade is converted to grade points on this scale, the one published by registrars such as Indiana University Indianapolis:
| Grade | Points | Grade | Points |
|---|---|---|---|
| A+ / A | 4.0 | C+ | 2.3 |
| A− | 3.7 | C | 2.0 |
| B+ | 3.3 | C− | 1.7 |
| B | 3.0 | D+ / D / D− | 1.3 / 1.0 / 0.7 |
| B− | 2.7 | F | 0.0 |
With the 4.3 option, an A+ earns 4.3, as at Cornell's ILR School. Then:
quality points = grade points × creditsGPA = total quality points ÷ total credits
Weighted option: Honors courses add 0.5 and AP/IB courses add 1.0, but only for grades of C− or better; a D or F gets no bonus. This mirrors one district's published policy (Allegany County Public Schools, Maryland: AP A = 5, Honors A = 4.5, D = 1 at every level). Weighting policies vary a lot by school. Broward County, Florida, for example, adds 1 point for Honors and 2 for AP, IB, AICE and dual enrollment (with conditions), so an AP A there can be worth 6.0. Check your school profile or handbook.
Cumulative GPA = (previous GPA × previous credits + this term's quality points) ÷ (previous credits + this term's credits).
Examples
1. A college semester
A (3 credits), B+ (4), A− (3) and B (3): 12 + 13.2 + 11.1 + 9 = 45.3 quality points over 13 credits, a 3.48 GPA. If the A were an A+ at a school that awards 4.3, the GPA would be 3.55.
2. Adding the semester to your record
With a previous 3.20 GPA over 45 credits, the same semester brings your cumulative GPA to 3.26 over 58 credits.
3. A high-school schedule with Honors and AP
Six one-credit classes: A in AP, B+ in Honors, A− regular, B in AP, A regular and D in AP.
| Grade | Level | Weighted points |
|---|---|---|
| A | AP | 5.0 |
| B+ | Honors | 3.8 |
| A− | Regular | 3.7 |
| B | AP | 4.0 |
| A | Regular | 4.0 |
| D | AP | 1.0 |
That is 21.5 quality points over 6 credits: a 3.58 weighted GPA against a 3.17 unweighted GPA. Notice that the D in AP stays at 1.0.
Reading your result
An unweighted GPA tops out at 4.0 (or 4.3 if your school rewards A+). A weighted GPA can go higher, so a 4.2 at one school and a 3.9 at another may describe similar transcripts. That is why you should always say which one you mean. The College Board notes that colleges may recalculate your GPA with their own criteria, for example by adjusting or removing Honors/AP weighting or dropping non-core courses.
Frequently asked questions
What is the difference between a weighted and an unweighted GPA?
An unweighted GPA treats every class the same: an A is 4.0 whether it is regular or AP. A weighted GPA gives extra points for harder courses. In this calculator that means +0.5 for Honors and +1.0 for AP/IB, so an A in AP becomes 5.0.
Do pass/fail classes and withdrawals count toward my GPA?
That depends on your school. Hobart and William Smith Colleges, for example, divide quality points only by graded credits, so pass/fail, W and incomplete notations are left out. Simply don't enter those courses. Check your own school's rules for repeated courses, which this calculator doesn't model.
Is an A+ worth 4.0 or 4.3?
It depends on the school. Indiana University Indianapolis counts A+ as 4.0, while Cornell's ILR School counts it as 4.3. Use the A+ switch to match your transcript.
How do I enter my previous GPA for a cumulative result?
Open Advanced options and enter both your GPA so far and the credits it covers; one without the other gives an error. Use the same basis as the courses you entered: a weighted previous GPA with the weighted option, an unweighted one without it.
What credits should I use for high-school classes?
Use the credit value on your report card or transcript. If your school gives the same credit to every class, entering 1 for each gives the same GPA as any equal number.
Why does my school report a different GPA?
Schools differ in bonus points, A+ values, which courses count and how they round. Your official GPA is the one on your transcript; use this tool to check the math and plan ahead.
