GPA Calculator

Understand Your Academic Standing in Seconds

Your Grade Point Average is more than a number on a transcript. It is a snapshot of your academic performance that colleges, scholarship committees, graduate schools, and even some employers use to screen applicants quickly. A small change in one class can move your cumulative GPA more than you expect, especially when credit hours and course weighting are involved. This free GPA calculator makes it easy to see exactly where you stand and what it will take to reach your target average.

What Is GPA?

GPA stands for Grade Point Average. It converts letter grades into a numerical score, usually on a 4.0 scale, and averages those scores based on the number of credits each course is worth. On the most common scale, an A equals 4.0, a B equals 3.0, a C equals 2.0, a D equals 1.0, and an F equals 0. Plus and minus modifiers adjust the value by roughly 0.33, so a B+ becomes 3.33 and a B- becomes 2.67.

Weighted GPA goes a step further by adding extra points for advanced coursework. An A in a regular class is typically 4.0, but the same grade in an honors course might be 4.5, and an A in an Advanced Placement or International Baccalaureate course might be 5.0. This system rewards students who challenge themselves with harder classes while keeping an unweighted measure available for direct comparison.

How to Use This Calculator

1. Add each course you want to include in your GPA calculation.
2. Select the letter grade you earned, including plus or minus variants.
3. Enter the credit hours for the course. A full-year class is usually 1.0 credit, while a semester class is often 0.5.
4. Choose the course type: regular, honors, or AP/IB. The calculator applies the appropriate weight automatically.
5. Read your results. The tool displays your unweighted GPA, weighted GPA, and total credits instantly as you make changes.

Common Use Cases

• College applications: calculate the GPA you will report or compare it against admitted-student averages for your target schools.
• Scholarship eligibility: many merit awards require a minimum GPA, often between 3.0 and 3.7, and some require full-time enrollment.
• Semester planning: estimate how future grades will affect your cumulative average before you register for classes.
• Academic standing: check whether you meet probation, honors list, dean's list, or graduation requirements.
• Resume building: list an accurate major or overall GPA when applying for internships, fellowships, and entry-level jobs.

Worked Example

Imagine a student taking four courses: English (A, 4 credits, regular), Math (B+, 4 credits, honors), Science (A-, 4 credits, AP), and History (B, 3 credits, regular). The unweighted calculation is (4.0 × 4) + (3.33 × 4) + (3.67 × 4) + (3.0 × 3) = 53.0 quality points, divided by 15 total credits, giving an unweighted GPA of 3.53. For the weighted calculation, honors adds 0.5 and AP adds 1.0: (4.0 × 4) + (3.83 × 4) + (4.67 × 4) + (3.0 × 3) = 59.0 quality points, divided by 15 credits, giving a weighted GPA of 3.93.

Tips for Accurate GPA Calculation

• Use your official transcript rather than memory to avoid mistakes with plus and minus grades.
• Check your school's weighting policy, because not all districts add the same bonus points or use the same scale.
• Exclude pass/fail courses unless your school specifically includes them in the GPA formula.
• Calculate both weighted and unweighted GPAs so you are ready for any application requirement.
• Update your GPA each semester to catch trends early and adjust your study plan before finals.
