Cumulative GPA Calculator

How credit hours change the GPA

This cumulative GPA calculator multiplies each letter by the credit hours for that course, adds those quality points, and divides by the total credits. An A in a 3-credit English class is 4.0 times 3, which is 12 quality points. A B in a 4-credit algebra class is 3.0 times 4, which is another 12. Together that is 24 quality points over 7 credits, so the term GPA is 24 divided by 7, or 3.43. Averaging 4.0 and 3.0 would give 3.50, and that figure is too high because algebra is worth more credit.

The course name can stay blank. Pick a letter from A through F, including plus and minus, and type the credits. A row with no letter, or with credits of 0, is skipped, so you can list next term before those grades exist. Add course puts another row on the list, and the trash icon removes one. The last row stays, so the table is never empty. An F is 0 points, and its credits still count: an A and an F, each worth 3 credits, is 12 quality points over 6 credits, which is a 2.00.

The term GPA, the credits, and the quality points update as you type. There is no calculate button. The line under the results shows the division, rounded to two decimal places.

Add the GPA already on your transcript

Under the course list, two optional boxes take the cumulative GPA you already have and the credits behind it. The new cumulative GPA is previous GPA times previous credits, plus this term's quality points, divided by previous credits plus this term's credits. A 3.20 on 45 credits, plus the 24 quality points and 7 credits from the example above, is (3.20 times 45 + 24) divided by (45 + 7), which is 168 divided by 52, or 3.23.

Combine the quality points. Two term GPAs match a straight average only when both terms have the same number of credits. A 3.80 on 12 credits and a 3.20 on 18 credits average to 3.50 if you treat the terms as equal, but the credit-weighted result is (3.80 times 12 + 3.20 times 18) divided by 30, which is 3.44. A strong 15-credit semester moves a 90-credit record less than it moves a 15-credit one.

Use credits that actually earn quality points. Pass/fail courses, audited classes, and many transfer credits sit on a transcript without them. If the school left them out, leave them out of the previous credits and out of the new rows. High school transcripts usually print a cumulative GPA and the credits behind it. Those two numbers go in the previous boxes, so the same form works as an HS GPA calculator when the school assigns credits. A previous GPA above 4.0 is allowed, because some transcripts are already weighted. New rows on this page still use the unweighted chart.

Unweighted GPA calculator for middle school and junior high

The Unweighted tab averages letter grades and ignores credit hours. Each class counts once. A, B+, A-, B, A, C+, and B is 4.0 + 3.3 + 3.7 + 3.0 + 4.0 + 2.3 + 3.0, which is 23.3. Divide by 7 classes and the GPA is 3.33. Art and PE count the same as math and English.

That is the usual middle school GPA calculator, and it is the jr high GPA calculator path as well. Most junior highs do not assign credits. If yours does, use the Credit-weighted tab and type those credits. An honors or gifted bump, such as an extra 0.5, is not added on this tab.

To fold in an earlier report card, enter the previous cumulative GPA and the number of classes behind it. A 3.10 across 12 classes is 37.2 points. Six new classes of A, B+, B, A-, A, and B+ are 4.0 + 3.3 + 3.0 + 3.7 + 4.0 + 3.3, which is 21.3 points. The new cumulative GPA is (37.2 + 21.3) divided by 18, or 3.25. Counting classes matters when one term has more classes than the other.

GPA converter to the 4.0 scale

The 4.0 converter tab turns one letter, or one percent, into grade points. The letters are 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, and F 0. There is no separate A+. On this scale an A is already the top, at 4.0.

A percent uses a common set of cutoffs: 93 to 100 is an A, 90 to 92 an A-, 87 to 89 a B+, 83 to 86 a B, 80 to 82 a B-, 77 to 79 a C+, 73 to 76 a C, 70 to 72 a C-, 67 to 69 a D+, 63 to 66 a D, 60 to 62 a D-, and anything under 60 an F. So 87% is a B+ and 3.3. A score of 92.5 is still an A-, because the A band starts at 93. A score of 89.5 is a B+.

Schools vary. Some start an A at 90 with no plus or minus, some give an A+ a 4.3, and some high schools put AP or honors on a 5.0 scale. An A in an AP class is 4.0 here. The points are the common unweighted scale, not a college's official scale, and not a weighted high school scale. If the handbook prints a different chart, use that chart.

Reading the number on a transcript

The result is a planning figure. A college registrar, a high school counselor, and a middle school report card can each use a different rule for repeated courses, withdrawals, and rounded decimals. If a course was retaken and the transcript replaced the first grade, count only the attempt the transcript counts. Quality points for each course are kept to two decimals, then the final division is rounded to two decimals for the GPA you see, so 24 divided by 7 shows as 3.43.

Nothing is uploaded or saved. The math runs in the browser, and refreshing the page clears the rows. If you are tracking a year, write down the cumulative GPA and the credit or class total before you leave. Those two numbers are enough to continue next term.
