GPA Calculator

Your GPA (grade point average) is one number that sums up your grades across all your classes, with each class counted by how many credits it’s worth. This calculator finds it on the standard 4.0 scale, weighted or unweighted, for one term or your whole transcript.

How to Use It

1. Keep My GPA selected. Add a row for each class: its name (optional), your letter grade and its credits.
2. For a weighted GPA, set each Honors class to Honors and each AP, IB or dual-enrollment class to AP / IB. Leave everything on Regular for an unweighted GPA.
3. For your cumulative GPA, open Add Your Previous GPA and enter the GPA and credits already on your transcript. The result then covers everything.
4. Press Calculate. After that, the result updates as you change anything.

Planning ahead? Switch to GPA I Need and enter your current GPA, the credits it covers, the GPA you want and how many credits you’ll take next. The calculator gives the average you need in those classes.

How It Works

Each letter grade has a point value: A and A+ are 4.0, A− is 3.7, B+ is 3.3, B is 3.0, and so on down to 0.0 for an F. Multiply each class’s points by its credits to get its quality points, then divide the total quality points by the total credits:

A weighted GPA adds 0.5 to an Honors class’s points and 1.0 to an AP or IB class’s (so an A in AP counts as 5.0). A previous GPA is folded in as if it were one more class: its GPA times its credits joins the quality points, and its credits join the total.

GPA I Need runs the same average backward:

Worked Example

A student takes Biology (A, 4 credits), English (B+, 3 credits) and History (A−, 3 credits):

• Biology: $4.0 \cdot 4 = 16.0$ quality points
• English: $3.3 \cdot 3 = 9.9$ quality points
• History: $3.7 \cdot 3 = 11.1$ quality points

That’s 37.0 quality points over 10 credits, a GPA of 3.70. If English is an Honors class, it counts as $3.8 \cdot 3 = 11.4$, and the weighted GPA is $38.5 \div 10 =$ 3.85.

Tips and Common Mistakes

• Use credits, not class count. A 4-credit lab class moves your GPA more than a 1-credit seminar with the same grade.
• Pass/fail and audited classes usually don’t count. Leave them out unless your school says otherwise.
• Retaken classes vary. Many schools replace the old grade instead of averaging both; enter only the grade your school counts.
• Don’t average two GPAs together. A 3.0 term and a 3.6 term only average to 3.3 if both had the same credits. Use Add Your Previous GPA instead, which weights each by its credits.
• Weighting rules differ. Some schools weight AP by 0.5, cap weighted GPAs, or don’t weight at all. Your transcript’s official GPA is the one colleges see.
