GPA Calculator

See the average before the transcript does

A semester GPA is not the mean of letter grades. Credits weight the result, and plus/minus steps change the points. This GPA calculator lets you add each course, pick a letter, set credit hours, and read a 4.0-scale average as you go. It is the same quality-point method U.S. registrars use, with a published plus/minus chart so there are no hidden mappings.

Use it to test “what if I get a B in chemistry” before drop deadlines. Because the math is local, you can sit in a library and scenario-plan without pasting a transcript into a random form.

The quality-point formula

GPA = Σ (points × credits) ÷ Σ credits. An A in a 4-credit course contributes 16 quality points. A B in a 3-credit course contributes 9. Those two courses together are 25 points over 7 credits, which is a 3.57 GPA—not a 3.5 that you would get by averaging 4.0 and 3.0 and ignoring credits.

The letter chart on this page is a widely used 4.0 plus/minus scale. Some schools make A+ a 4.3, some cap every A at 4.0, and some weight AP or honors with an extra point. If your handbook disagrees, the calculator cannot override the handbook. Use it as a close estimate and confirm with the registrar’s tool when the number is for probation, Latin honors, or a graduate application.

How to use it

Add a row per course. Credits are usually 1, 3, or 4; labs may be 1. Delete a row if you dropped the class. The GPA at the top is live. Empty lists show a dash instead of a fake 0.00, because zero credits is not a GPA.

For a cumulative figure, enter prior courses too, or combine last term’s official GPA with this term by converting the old GPA back into quality points: old GPA × old credits, then add this term and divide by all credits. This page does not fetch your campus SIS.

Examples

A (3 credits) and B (3 credits) is (12 + 9) / 6 = 3.50. A (4), C (3), B (3) is (16 + 6 + 9) / 10 = 3.10. Three equal-credit A− grades are 3.70. One F in a 4-credit course next to three 3-credit A’s is (0 + 36) / 13 ≈ 2.77—the credit weight of the F is the whole story.

If your syllabus gives percentages, convert to a letter with your syllabus scale first. A 91% might be an A− on one campus and an A on another. The percentage calculator can do the raw percent; it cannot invent your department’s cutoffs.

What GPA is for—and what it is not

GPA is a registrar statistic. Employers and labs often care more about the last two years, the major GPA, or the work itself. Do not let a tenth of a point become the only story you tell about a term that also included a job or a family problem.

Repeated courses, withdrawals, and incomplete grades follow campus policy. This tool only averages the rows you add.

Frequently asked questions

How is weighted GPA calculated?

Convert each letter to points, multiply by credit hours, add those quality points, and divide by total credits. A 4-credit A counts more than a 1-credit A.

What letter-to-point scale does this use?

A 4.0, A− 3.7, B+ 3.3, B 3.0, B− 2.7, C+ 2.3, C 2.0, C− 1.7, D+ 1.3, D 1.0, D− 0.7, F 0.0. Your campus may differ by a tenth.

Can I calculate cumulative GPA across terms?

Add every course you want in the average, including older terms. For a true cumulative number you must include all graded credits, not only this semester.

Do pass/fail courses count?

Usually they do not enter the GPA. Leave them off this list unless your school assigns points for them.

Are my grades stored?

No. The list lives in the page until you close it.
