About this GPA Calculator

GPA calculator: semester and cumulative GPA from courses, credits and grades It is one of the Work and School on ToolUstad, and like every tool here it runs entirely in your browser: nothing you type, paste or open is uploaded to a server, and there is no sign-up or usage limit.

What is a GPA calculator?

GPA stands for grade point average, the single number that summarises a student's grades. In the United States it runs from 0 to 4.0 on the standard scale, with A worth 4 points, B worth 3, C worth 2, D worth 1 and F worth 0. Each course is weighted by its credits, so a 4-credit course moves the GPA more than a 1-credit course. The result is the number colleges, scholarship committees and employers ask for, and it is the number that decides honours lists, academic probation and graduation.

The complication is that not every school grades the same way. Some use a 4.3 scale where A+ counts for 4.3. Some weight harder courses, giving Honors an extra half point and AP a full extra point, so an A in AP Calculus can be worth 5.0 on a 5.0 scale. And semester GPA is not the same as cumulative GPA: the first covers one term, the second covers everything, weighted by credits. This calculator handles all three scales, weighted and unweighted modes, and prior credits, so the number it gives is the one your school would give.

How does GPA maths work?

Each grade converts to points, the points are multiplied by the course credits to give quality points, the quality points are added up, and the total is divided by the total credits. With Biology at A (4.0 times 3 credits is 12 quality points), English at B+ (3.3 times 3 is 9.9), Calculus at A- in Honors (3.7 plus 0.5 is 4.2, times 4 credits is 16.8) and History at B (3.0 times 3 is 9), the total is 47.7 quality points over 13 credits, a GPA of 3.67. The planner works backwards from a target: it figures out what average grade next term would lift the cumulative GPA to the target, given the credits already banked.

When and why to use a GPA calculator

At the end of a term: check the semester GPA before grades are finalised, while there is still time to ask about a grade.
Before choosing courses: see how a hard AP course and an easy elective each move the cumulative GPA.
College applications: most applications ask for cumulative GPA, and a wrong number here is an avoidable mistake.

Best practices

Enter credits exactly as the transcript shows them: a 4-credit lab counts more than a 3-credit lecture, and guessing the credits is the commonest error.
Use the same scale your school uses. A 3.67 on a 4.0 scale is not the same achievement as a 3.67 on a 5.0 scale.

Common mistakes to avoid

Averaging letter grades directly: a B in a 4-credit course and an A in a 1-credit course do not average to an A-minus, because the credits weight them.
Forgetting that a failed course still counts its credits in the denominator until it is retaken and replaced, if your school allows replacement.
Mixing weighted and unweighted figures in one calculation: pick one mode and stay in it.

Who is the GPA calculator for?

High school and college students, their parents, and teachers and counsellors who advise them. It is also used by adult learners returning to study, who need to know where they stand before committing to a full course load. The tool is an estimator: your school's official transcript is the final word, especially where repeated courses, pass-fail grades and transfer credits are involved.

Learn: how to use the GPA Calculator

Add one row per course: the course name, its credits, and the grade you earned or expect.
Pick your scale and whether Honors and AP courses carry extra weight, then add any prior GPA and credits for a cumulative figure.
Read the semester and cumulative GPA, then set a target GPA to see the average grade you need next term.

Worked example

Biology (3 credits, A), English (3 credits, B+), Calculus (4 credits, A-, Honors) and History (3 credits, B): 13 credits, 45.7 quality points, semester GPA 3.52. Switch on weighted grades and the Honors Calculus A- earns 4.2 points instead of 3.7, lifting the total to 47.7 points and the GPA to 3.67.

Frequently asked questions

How is GPA calculated?

Each grade is worth points (A is 4.0, B is 3.0, C is 2.0, D is 1.0, F is 0). Points are multiplied by the course credits to get quality points, the quality points are added up, and the total is divided by total credits.

What is a weighted GPA?

Weighted GPA gives extra points for harder courses: usually +0.5 for Honors and +1.0 for AP. An A in an AP course can then be worth 5.0 on a 5.0 scale, while the same A in a regular course is 4.0.

What is the difference between semester and cumulative GPA?

Semester GPA covers one term only. Cumulative GPA covers every term, weighting each by its credits. One strong term moves a cumulative GPA slowly once you have many prior credits.

Can I use percent grades?

Yes. Switch grade entry to percent and the tool converts each percent to the standard 4.0 points: 93 to 100 is 4.0, 90 to 92 is 3.7, 87 to 89 is 3.3, and so on down to 0 for anything below 65.

What is a good GPA?

On a 4.0 scale, 3.5 and above is strong for most colleges, 3.0 is the common scholarship cutoff, and 2.0 is usually the minimum to stay in good standing. Competitive universities often expect 3.7 or higher from applicants.

Do colleges look at weighted or unweighted GPA?

Both, but they usually recalculate it themselves on their own scale, because high schools weight differently. The unweighted GPA is the safer number to quote, with weighted GPA as extra context.

Can I raise my GPA quickly?

Slowly, once you have many credits banked, because each new term is a small share of the total. The planner shows the maths: with 60 credits at 3.0, even a perfect 4.0 term of 15 credits only lifts the cumulative GPA to 3.2.

What grades do I need next term to reach my target GPA?
