How To Calculate Your Unweighted GPA Guide

Understanding What an Unweighted GPA Is

Your Grade Point Average, or GPA, is a number that represents your overall academic performance. It combines all the grades you've earned into a single score. An unweighted GPA treats all courses equally, regardless of their difficulty level. This means that getting an A in a regular English class counts the same as getting an A in an honors or Advanced Placement class.

The unweighted GPA system uses a standard 4.0 scale in most U.S. schools. Each letter grade corresponds to a specific numerical value. An A typically equals 4.0, a B equals 3.0, a C equals 2.0, a D equals 1.0, and an F equals 0.0. Some schools use plus and minus grades, which add small decimal adjustments. For example, an A-minus might be 3.7, and a B-plus might be 3.3.

Unweighted GPAs are different from weighted GPAs. Many high schools calculate both types. A weighted GPA gives extra point value to advanced courses like honors or AP classes, typically adding 0.5 or 1.0 additional points to those grades. Unweighted GPAs ignore this distinction entirely. If you earned a 4.0 unweighted GPA, it means you got all A's across every class you took, whether those classes were basic or advanced level.

Most colleges and universities focus on your unweighted GPA when making admission decisions, though many also review your course rigor. Understanding your unweighted GPA helps you see your baseline academic performance without the boost that advanced courses provide. This gives a clearer picture of your actual grade performance across all subjects.

Practical Takeaway: Your unweighted GPA shows your pure academic performance on a level playing field. Calculate it to understand your true grades before any adjustments for course difficulty.

Locating Your Grade Information and Grade Scale

Before you can calculate your unweighted GPA, you need to gather all your grades. Your school's grading system determines how you'll convert letter grades to numerical values. Start by checking your report cards or transcript. Most high schools provide transcripts that list every course you've taken and the grade you received. You can usually request a copy from your school's registrar office or download it through your school's online portal if one exists.

Next, you need to identify your school's specific grade scale. Not all schools use exactly the same conversion system. The most common scale is: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. However, some schools use different scales. Some schools might use A = 4.0, B = 3.5, C = 3.0, D = 2.0, F = 0.0. Others use a 100-point scale where 90-100 is an A, 80-89 is a B, and so on. Your school's website, student handbook, or registrar office can provide the exact scale your school uses.

If your school uses plus and minus grades, you'll need those specific values too. Common conversions include: A+ = 4.0 or 4.3, A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, and so on. Some schools don't use A+ or may cap it at 4.0. Call your school's registrar or check your student handbook to confirm.

Make a list of every class you want to include in your calculation. For an unweighted GPA, you typically include all courses except electives like PE or study hall, though this varies by school. Some schools include everything; others exclude certain non-academic courses. Your transcript usually makes this clear by showing which courses "count" toward your GPA.

Practical Takeaway: Collect your transcript and verify your school's exact grade scale and conversion values before starting any calculations. This ensures accuracy.

Converting Letter Grades to Numerical Values

Once you have your grades and your school's grade scale, convert each letter grade to its numerical equivalent. This is the foundation of your calculation. Write down each course name and its corresponding letter grade in one column. In the next column, write the numerical value for that grade according to your school's scale.

For example, imagine a student with these grades in a typical 4.0 scale school: English A, History B, Mathematics A, Science B, Spanish C. Using the standard scale (A = 4.0, B = 3.0, C = 2.0), the conversions are: English 4.0, History 3.0, Mathematics 4.0, Science 3.0, Spanish 2.0.

If your school uses plus and minus grades, be precise with these conversions. A student who received an A- in one class and an A in another should record different values. Using a scale where A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, the student would record the correct decimals for each.

Pay special attention to failing grades. An F equals 0.0 on the standard scale, regardless of plus or minus variations. This significantly impacts your overall GPA because it brings down your average considerably. For instance, one F among several A's and B's will noticeably lower your unweighted GPA.

Some students take courses multiple times if they initially received a low grade. Policies about which grade counts vary by school. Some schools use only the most recent grade; others average all attempts; others keep all grades on the transcript but only count the highest. Check with your registrar about your school's policy. Only include the grades that officially count toward your GPA according to your school's policy.

Practical Takeaway: Create a clear chart listing each course and its corresponding numerical grade value. Double-check conversions, especially for plus and minus grades.

Performing the GPA Calculation

Calculating your unweighted GPA involves a straightforward mathematical process. Add together all your converted numerical grades, then divide by the number of courses. The formula is: Total of all grade points ÷ Number of courses = Unweighted GPA.

Let's work through a detailed example. Suppose a student completed nine courses with these grades: English A (4.0), History B (3.0), Mathematics A (4.0), Science B (3.0), Spanish C (2.0), Art A (4.0), Physical Education A (4.0), Elective B (3.0), and Foreign Language B (3.0). First, add all the numerical values: 4.0 + 3.0 + 4.0 + 3.0 + 2.0 + 4.0 + 4.0 + 3.0 + 3.0 = 30.0. Next, count the total number of courses: 9 courses. Finally, divide: 30.0 ÷ 9 = 3.33. This student's unweighted GPA is 3.33.

It's important to include every course that your school counts toward GPA. Some students wonder whether to include PE, art, or other non-traditional classes. If your school's official GPA calculation includes these courses, you must include them in your calculation. If your school excludes certain courses, exclude them too. Your transcript or registrar can clarify which courses count.

Use a calculator to avoid arithmetic errors, especially if you have many courses. Even small errors compound across calculations. Round your final answer to two decimal places, which is the standard format schools use. A GPA of 3.333 would round to 3.33.

Keep in mind that this calculation gives you a snapshot of your GPA at a particular point in time. As you earn new grades, your GPA changes. If you take additional courses next semester, you'll recalculate by adding those new grades to your total and dividing by the new total number of courses. Your GPA is not fixed; it fluctuates with every new grade.

Practical Takeaway: Add all numerical grade values together, divide by the total number of courses, and round to
