GPA Calculator
Add your classes, credits and letter grades to calculate your GPA on the 4.0 scale, with optional honors/AP weighting and cumulative GPA.
| Class | Credits | Grade | Type | Remove |
|---|---|---|---|---|
A common convention is +0.5 for honors and +1.0 for AP/IB on top of the 4.0 points. Change the bonus to match your school; an F always stays 0.Weighting for honors and AP/IB (schools vary)
Cumulative GPA (optional)
How to calculate your GPA
GPA (grade point average) summarizes your grades as one number. Each letter grade has a point value, and classes with more credits count more. To calculate it, multiply each class's grade points by its credits, add those up, and divide by the total number of credits.
Weighted GPA rewards harder coursework. This calculator adds 0.5 to the grade points of honors classes and 1.0 to AP/IB classes (an F stays 0). Cumulative GPA combines this term with your previous record: (prior GPA × prior credits + this term's grade points) ÷ (prior credits + this term's credits).
Percent to GPA converter
Enter a percentage to see the letter grade and 4.0 GPA points.
This uses a common US conversion from percentages to letter grades and 4.0 grade points. Grading scales vary by school and even by teacher: some use 90–100 for every A, some use a 7-point scale, and some award 4.3 for an A+. Use your school's published scale if it differs.
| Percent | Letter | GPA |
|---|---|---|
| 97–100 | A+ | 4.0 |
| 93–96 | A | 4.0 |
| 90–92 | A- | 3.7 |
| 87–89 | B+ | 3.3 |
| 83–86 | B | 3.0 |
| 80–82 | B- | 2.7 |
| 77–79 | C+ | 2.3 |
| 73–76 | C | 2.0 |
| 70–72 | C- | 1.7 |
| 67–69 | D+ | 1.3 |
| 65–66 | D | 1.0 |
| Below 65 | F | 0.0 |
Percentages are rounded down to a whole number before lookup, so 89.6% counts as 89 (B+). Many teachers round up instead, so check how your school handles decimals.
Target GPA calculator
Enter your current GPA, credits completed and target GPA.
The grade needed is (target × total credits − current GPA × credits completed) ÷ next-term credits. For example, with a 3.0 GPA over 30 credits and a 3.2 target, you need a 3.60 average across your next 15 credits. The credits figure shows how many credits of 4.0 grades it would take to reach the target, which shows how much harder it becomes to move a GPA once many credits are on record. It uses unweighted grades.
Weighted vs unweighted GPA
Unweighted GPA treats every class the same on the 4.0 scale, so an A is 4.0 whether the class is regular, honors or AP. Weighted GPA adds a bonus for harder classes, so it can go above 4.0. This calculator uses the common +0.5 (honors) and +1.0 (AP/IB) convention by default, and you can edit both bonuses above. Many high schools report both numbers; colleges often recalculate GPA with their own rules.
Example (four 1-credit classes): A in AP, B in honors, B in a regular class and A− in a regular class. Unweighted: (4.0 + 3.0 + 3.0 + 3.7) ÷ 4 = 3.43. Weighted: (5.0 + 3.5 + 3.0 + 3.7) ÷ 4 = 3.80.
High school vs college GPA
High schools often give each class the same weight and may add honors/AP bonuses. Colleges usually weight each course by its credit hours and rarely add bonuses, so college GPA is normally unweighted. Pass/fail and withdrawn (W) courses usually do not count toward GPA. See weighted vs unweighted GPA and how to calculate college GPA for more.
How to raise your GPA
- Focus on high-credit classes. A grade in a 4-credit class moves your GPA more than the same grade in a 1-credit class, so put extra effort where the credits are.
- Act early in the term. Early quizzes and assignments are easier to recover from than a low final exam. Use the percent converter to see which letter your current average maps to and how close you are to the next one.
- Ask about retakes and grade replacement. Some schools replace or average a failed or low grade when you retake the class. Policies differ, so check with your counselor or registrar.
- Use weighted courses carefully. Honors and AP/IB classes can raise a weighted GPA, but only if you can keep your grade up; they usually do not change an unweighted GPA.
- Set a realistic target. Use the target GPA calculator to see the average you need next term. Raising a GPA is fastest early on, while you have fewer credits on record.
- Get help when you need it. Office hours, tutoring centers and study groups are often free and can make the difference between grade levels.
4.0 grade scale used
| Letter grade | Grade points |
|---|---|
| A+ | 4.0 |
| A | 4.0 |
| A- | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B- | 2.7 |

| C | 2.0 |
| C- | 1.7 |

Pass/fail classes usually do not count toward GPA, so leave them out.
Frequently asked questions
What is the difference between weighted and unweighted GPA?
Unweighted GPA uses the standard 4.0 scale for every class. Weighted GPA adds a bonus for harder classes — in this calculator 0.5 points for honors and 1.0 point for AP or IB — so it can go above 4.0. Schools use different weights, so check your school's policy.
How is GPA calculated?
Each grade is converted to grade points, multiplied by the class credits, and the totals are added. That sum is divided by the total credits. Example: an A (4.0) in a 3-credit class and a B (3.0) in a 4-credit class give (12 + 12) ÷ 7 = 3.43.
How do I calculate my cumulative GPA?
Enter your current cumulative GPA and the credits it covers in the cumulative section. The calculator multiplies them to get your prior grade points, adds this term's grade points and credits, and divides again.
Does an A+ count as 4.3?
On this calculator an A+ counts as 4.0, which is the most common practice in US high schools and colleges. A few schools award 4.3; adjust your expectations if yours does.
How many credits should I enter for a high school class?
Many high schools count a full-year class as 1 credit and a semester class as 0.5. Colleges usually use the credit hours listed in the course catalog, often 3 or 4.
Is 80% what GPA?
On the common scale used here, 80% is a B-, which is 2.7 on the 4.0 scale. Schools that count 80–89 as a plain B would give 3.0, so check your school's scale.
Is a 3.4 GPA good?
A 3.4 is a little above a B+ (3.3) average on the 4.0 scale, between a B+ and an A- (3.7). Whether it is good for you depends on your goals: colleges and programs have different expectations, and many look at course difficulty and the rest of your application too. Check the published admission information of the schools you are interested in.
What is 70% in GPA?
On the common scale used here, 70% is a C-, which is 1.7 on the 4.0 scale. On a plain 10-point scale where 70–79 is a C, it would be 2.0.
How do I figure out my GPA?
Convert each grade to grade points (A = 4.0, B = 3.0 and so on), multiply by the class credits, add the results, and divide by the total credits. Enter your classes in the calculator at the top of this page to do it automatically, or use the percent converter if your grades are percentages.
What GPA do I need next term to reach my target?
Use the target GPA calculator: enter your current GPA, credits completed, target and next term's credits. It shows the average you need, or tells you if the target is above 4.0 and not reachable in one term.
