GPA Calculator: Weighted and Unweighted GPA

Add your courses, credits and grades. Letters (B+), percentages (88) and grade points (3.3) all work, and Honors or AP courses give you your weighted GPA at the same time.
A+ counts as
Add your GPA from earlier semesters
Grades: A−, 88 (a percentage) or 3.7 (grade points). P, NP, W and I are not counted. Type: Honors adds 0.5 and AP / IB adds 1.0 to the weighted GPA, the most common policy. ↻ Retake: tick it on the new attempt and the earlier course with the same name drops out of your GPA. Paste rows from a spreadsheet (course, credits, grade) into any course box to fill a whole semester. Everything is saved on this device only.

How to Use the GPA Calculator

  1. Pick how your school counts an A+: 4.0 (most high schools) or 4.3 (many colleges).

  2. Enter each course's credits and grade. A letter, a percentage or grade points all work; for a high school class, 1 credit per course is fine.

  3. Set the type to Honors or AP / IB where it applies. Your weighted GPA appears next to the unweighted one.

  4. Add more semesters, or your earlier cumulative GPA, to get your cumulative GPA and a semester-by-semester trend.

  5. Use the GPA Planner to see what you need next semester, then print or save a GPA report.

Weighted vs. Unweighted GPA, With a Real Example

An unweighted GPA treats every class the same: an A is 4.0 whether it's in regular English or AP Chemistry. A weighted GPA rewards harder classes, most often with +0.5 for Honors and +1.0 for AP or IB. Here is one high school semester of five 1-credit classes:

CourseTypeGradeUnweightedWeighted
English 11HonorsA−3.74.2
BiologyAPB+3.34.3
Algebra IIRegularA4.04.0
U.S. HistoryRegularB3.03.0
Spanish IIIRegularA−3.73.7
GPA3.543.84

The same report card is a 3.54 unweighted and a 3.84 weighted. Colleges often recalculate GPAs their own way, so it helps to know both numbers. To turn a weighted GPA back into the 4.0 scale, use the weighted to unweighted GPA calculator.

4.0 or 4.3: How Your School Counts an A+

Schools agree on most grade points but not on the A+. Here is the full letter-to-points table under both rules:

LetterPercent4.0 scale4.3 scale
A+97–100%4.04.3
A93–96%4.04.0
A−90–92%3.73.7
B+87–89%3.33.3
B83–86%3.03.0
B−80–82%2.72.7
C+77–79%2.32.3
C73–76%2.02.0
C−70–72%1.71.7
D+67–69%1.31.3
D63–66%1.01.0
D−60–62%0.70.7
FBelow 60%0.00.0

So four 3-credit classes graded A+, A+, A and B+ give 3.83 on a 4.0 scale but 3.98 on a 4.3 scale. Percent ranges also vary by school; the calculator converts percentages with the ranges in this table. For what each GPA level means, see the GPA scale guide, or convert in the other direction with the GPA to letter grade calculator.

How Much Can One Semester Change Your GPA?

The more credits you've already earned, the harder your GPA is to move. This table shows your new cumulative GPA after one more semester of 15 credits of straight A's (4.0), depending on where you start:

Starting GPAAfter 15 creditsAfter 30 creditsAfter 60 creditsAfter 90 credits
2.53.253.002.802.71
3.03.503.333.203.14
3.53.753.673.603.57

A freshman with a 3.0 after 15 credits can reach a 3.5 with one perfect semester. A junior with the same 3.0 after 90 credits only reaches 3.14. That's why the planner above tells you when a goal is out of reach this term and how many credits it would take instead.

Retaking a Class: Replace or Average?

Suppose you have a 2.80 GPA over 60 credits, including an F in a 3-credit course, and you retake it for a B. How much that helps depends on your school's policy:

School policyHow it's countedNew GPA
Grade replacementThe F is removed; the B counts over the same 60 credits2.95
Both attempts countThe F stays; the B adds 3 more credits (63 total)2.81

Replacement is worth more than five times as much here. In the calculator, tick ↻ on the new attempt and give it the same course name as the original to use grade replacement.

GPA Calculator FAQs

How do I calculate my GPA?
Multiply each course's grade points by its credits, add those up, and divide by your total credits. For example, an A (4.0) in a 3-credit class and a B (3.0) in a 4-credit class give (4.0×3 + 3.0×4) ÷ 7 = 3.43. The calculator above does this for every course and semester at once.
What is the difference between weighted and unweighted GPA?
An unweighted GPA uses the same 0–4.0 points for every class. A weighted GPA gives extra points for harder classes, most often +0.5 for Honors and +1.0 for AP or IB, so an A in an AP class counts as 5.0. Colleges usually see both, which is why the calculator shows them side by side.
How much do Honors and AP classes add to GPA?
The most common policy is +0.5 for Honors and +1.0 for AP, IB and dual-enrollment classes, added only to passing grades. Some schools use different values or cap the weighted GPA, so check your school's handbook if the numbers need to match your transcript exactly.
Is an A+ worth 4.0 or 4.3?
Most US high schools count an A+ as 4.0, the same as an A. Many colleges give it 4.3. Use the A+ counts as switch at the top of the calculator to match your school; only A+ grades are affected.
How do I calculate my cumulative GPA?
Open Add your GPA from earlier semesters and enter your current cumulative GPA and the credits it covers, then add this semester's courses. The calculator combines them by credits, which is how schools compute a cumulative GPA. You can also add several semesters and see the cumulative GPA after each one.
Does retaking a class replace the old grade?
It depends on the school. Many colleges replace the earlier grade with the new one; others average both attempts. Tick the ↻ box on the new attempt to replace the earlier course with the same name, or leave it unticked to count both. The example below shows how much the choice can change your GPA.
Do pass/fail classes count toward GPA?
Usually not. Grades such as P, NP, W (withdrawal) and I (incomplete) earn credits or appear on the transcript but carry no grade points, so the calculator leaves them out of your GPA.
How do I convert a percentage grade to GPA?
Type the percentage, such as 88, straight into the grade box. It is converted to a letter on the standard scale (88% is a B+) and then to grade points (3.3). For single conversions, the grade to GPA calculator is quicker.
What GPA do I need next semester to reach my goal?
Use the GPA Planner below the calculator. Enter a target and the credits you'll take next, and it shows the average you need, what that means in letter grades, and whether the target is reachable this term. With a 3.2 GPA over 45 credits, reaching 3.5 after a 15-credit semester would need a 4.4 average, which is out of reach; straight A's would bring you to 3.4.
What is a good GPA?
On a 4.0 scale, a 3.0 is a solid B average, a 3.5 is typically enough for a Dean's List, and a 3.7 or higher is competitive for selective colleges. What counts as good depends on your goals; the GPA scale guide explains each level in detail.
