GPA Calculator
Your GPA is the average of your grade points, weighted by how many credits each course is worth. Add your courses to get this term's GPA, combine it with your previous GPA for your cumulative GPA, switch on weighting for honors and AP classes, or find the GPA you need to reach a goal.
A 4-credit class counts more than a 1-credit class
Letter Grades to Grade Points
The standard 4.0 scale. Some colleges give an A+ 4.33; switch the scale in the calculator if yours does.
| Grade | Points | Honors | AP / IB |
|---|---|---|---|
| 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 |
Only have a percent? The Grade Calculator turns it into a letter grade first. An F usually earns no extra weighting.
A Semester, Step by Step
Multiply each grade's points by the course credits, add the results, and divide by the total credits.
| Course | Grade | Points × credits | Quality points |
|---|---|---|---|
| Math | A | 4.0 × 4 | 16.0 |
| English | B+ | 3.3 × 3 | 9.9 |
| Biology | A− | 3.7 × 4 | 14.8 |
| History | B | 3.0 × 3 | 9.0 |
| Total | 14 credits | 49.7 → 3.55 |
Extra Points for Harder Classes
High schools often weight honors and AP classes so a B in AP isn't worth less than an A in a regular class.
Unweighted
Every class on the same 4.0 scale. This is what most colleges report.
Honors
Half a point extra on top of the usual grade points.
AP / IB
A full point extra, so a weighted GPA can go above 4.0.
Combine Terms by Credits
Your cumulative GPA covers every credit you've taken. Weight each term by its credits; never average two GPAs directly.

Rebuild Your Old Points
A 3.2 GPA over 60 credits is 3.2 × 60 = 192 quality points.
-
Add This Term
This semester added 49.7 quality points over 14 credits: 241.7 points over 74 credits in all.
-
Divide
241.7 ÷ 74 = 3.27. A great term moves a GPA with many credits only a little.

Frequently Asked Questions
How do you calculate GPA?
Turn each grade into points, multiply by the course's credits, add them up, and divide by the total credits. A (4 credits), B+ (3), A− (4) and B (3) give 49.7 ÷ 14 = 3.55.
What is the difference between weighted and unweighted GPA?
Unweighted uses the same 4.0 scale for every class; weighted adds points for harder ones, usually +0.5 for honors and +1.0 for AP or IB, so an AP A counts as 5.0. Colleges often recalculate GPAs their own way.
How do you calculate cumulative GPA?
Weight each term by its credits. A 3.2 over 60 credits plus a 3.55 term over 14 credits is (192 + 49.7) ÷ 74 = 3.27. Averaging 3.2 and 3.55 directly would wrongly give 3.38.
What GPA do I need to raise my cumulative GPA?
Needed = (target × total credits − current GPA × current credits) ÷ new credits. With a 2.8 over 90 credits, reaching 3.0 needs a 4.2 in a 15-credit term (impossible), but a 3.6 over the next 30 credits.
Do pass/fail classes count toward GPA?
Usually not. A pass earns credit but no grade points, so leave those classes out. Whether a failed pass/fail class counts as an F depends on your school.
Is a 3.5 GPA good?
Yes, for most purposes. A 3.5 is a B+ to A− average, above the typical US college average of about 3.0 to 3.2, and it meets many honors and scholarship cut-offs.
