This GPA calculator averages four grade-point numbers on an equal-weight, unweighted scale. Add the four numbers and divide by four. A 4.0, a 3.0, a 3.7, and a 3.3 produce 3.5, which the calculator shows as 3.5 GPA.
It does not multiply by credit hours, drop a lowest grade, apply honors or AP weights, or convert letters for you. Schools do not all use the same points for A− and B+. The table on this page is a common US undergraduate scale so you can type a number, not a promise that your registrar uses it. If your courses have different credits, the equal average is the wrong official GPA even when the arithmetic is right.
How to use this calculator
- Convert each course to grade points yourself, using your school's scale. A common A is 4.0.
- Enter the four grade-point numbers. The sample is 4, 3, 3.7, and 3.3.
- Press Calculate. The headline is the sum divided by 4, with at most two decimal places.
- If you have a different number of courses, do not invent grades to fill the extra boxes. Average the real courses by hand, or see the note below about repeating values.
How an unweighted four-course GPA is averaged
Every field has the same weight. The calculator does not ask for credits, and it always divides by 4, not by the number of classes you wish you had entered. The sample sum is 4 + 3 + 3.7 + 3.3 = 14, and 14 / 4 = 3.5 exactly, shown as 3.5 GPA.
The display keeps at most two decimal places. A sum of 10.7 divided by 4 is 2.675, which displays as 2.68 GPA. Trailing zeros are not forced, so a perfect average displays as 4 GPA rather than 4.00, and a zero average displays as 0 GPA.
Nothing clamps the inputs to the range 0 through 4. A school that awards 4.3 for an A+ will be averaged as typed. A number typed by mistake, such as 40 instead of 4.0, will also be averaged as typed. The form does not know the difference.
Formula
Unweighted GPA = (grade 1 + grade 2 + grade 3 + grade 4) / 4 Credit-weighted GPA, which this form does not compute: (sum of grade points × credits) / (sum of credits)
Equal weights match a credit-weighted GPA only when every course has the same number of credits. A 4.0 on a 1-credit lab and a 2.0 on a 3-credit course have a weighted average of (4×1 + 2×3) / 4 = 2.5. The unweighted mean of 4 and 2 is 3.0. Those are different numbers, and this calculator can only produce the unweighted kind.
If you truly have two courses of equal credit, entering each grade twice (4, 2, 4, 2) still averages to 3.0, which matches the two-course unweighted mean. If you have three courses, duplicating only one of them to fill the fourth box changes the weight. Don't do that. Add the three grades and divide by 3 yourself.
Worked unweighted GPA examples
4.0, 3.0, 3.7, and 3.3
Sum = 4 + 3 + 3.7 + 3.3 = 14. Average = 14 / 4 = 3.5. The calculator shows 3.5 GPA, and the detail line says the result is an unweighted average on a 4.0 scale.
On the common letter scale below, those points are an A, a B, an A−, and a B+. Your campus might assign A− a 3.67 instead of 3.7. If it does, type 3.67. The calculator will not translate the letters A− and B+ on its own.
All A grades, and a failing slate
Enter 4, 4, 4, and 4. The average is 4, and the calculator shows 4 GPA. Enter 0, 0, 0, and 0. The calculator shows 0 GPA. Both are exact. The display does not pad them to two decimal places.
A student with a 4.0 in three classes and a blank fourth class should not type 0 unless that fourth class is actually an F. A typed 0 is a grade point of zero and pulls the average down to 3 if the other three are 4.0: (4 + 4 + 4 + 0) / 4 = 3.
A 2.68 average, and a credit-weighted contrast
Enter 3, 3, 2, and 2.7. The sum is 10.7. Divided by 4, that is 2.675, and the calculator shows 2.68 GPA. The third decimal was 5, so the displayed hundredths place rounds up.
Those four numbers ignore credits. Suppose instead the grades were a 4.0 worth 1 credit and a 2.0 worth 3 credits, and you only had those two courses. The credit-weighted GPA is (4×1 + 2×3) / (1 + 3) = 10 / 4 = 2.5. An equal average of 4 and 2 is 3. This tool cannot accept the credit column, so it cannot show 2.5 for that pair. Use the weighted formula when credits differ.
A common US 4.0 letter scale
| Letter | Points often typed | Letter | Points often typed |
|---|---|---|---|
| A | 4.0 | C | 2.0 |
| A− | 3.7 | C− | 1.7 |
| B+ | 3.3 | D+ | 1.3 |
| B | 3.0 | D | 1.0 |
| B− | 2.7 | F | 0.0 |
| C+ | 2.3 | A+ (some schools) | 4.0 or 4.3 |
What an equal average of four numbers misses
Official GPAs are usually credit-weighted, term by term and cumulatively. Repeating a course may replace the old grade or average with it, depending on the school. Honors, AP, and IB courses are sometimes weighted to 4.5 or 5.0. None of those rules are in this form.
Plus and minus cutoffs differ. A 90% might be an A at one college and an A− at another, and an A− might be 3.7, 3.67, or 4.0. Convert using the scale on your transcript legend, then type the points.
The box count is four. Five courses cannot be averaged here without changing their weights. One course cannot be averaged by typing it once and filling the rest with zeros. Zeros are grades.
Frequently asked questions
Does this GPA calculator weight courses by credit hours?
No. It adds four grade-point numbers and divides by four. A 4.0 worth one credit and a 2.0 worth three credits have a credit-weighted average of 2.5, while the unweighted mean of 4 and 2 is 3. Use the weighted formula when credits differ.
What if I have fewer or more than four courses?
This form always divides by four. Two equal-credit courses can be entered twice each without changing an unweighted mean. Three courses should be added and divided by three yourself. Do not fill empty boxes with 0 unless the grade is actually zero.
Which letter grades match 4.0, 3.7, and 3.3?
On a common US scale, A is 4.0, A− is 3.7, and B+ is 3.3. Schools differ, especially on A− (sometimes 3.67) and A+ (sometimes 4.3). Type the points from your own scale. The calculator does not read letters.
Can I enter a grade above 4.0?
Yes. The average is not capped. If your campus awards 4.3 for A+, enter 4.3 and it will be included in the sum. A typo such as 40 is also included, so check the four boxes before you read the headline.
Will this match the GPA on my transcript?
Only if the transcript average is an unweighted mean of these same four numbers. Credit hours, repeated courses, pass/fail grades, and weighted honors points are all reasons a registrar total will differ. The result line says the figure is an unweighted average on a 4.0 scale.
