Our GPA Calculator makes it simple to convert your course grades and credits into a clear, accurate grade point average. Whether you’re tracking semester progress, planning scholarship applications, or checking graduation eligibility, this tool helps you see both unweighted and weighted GPA in seconds.
What the GPA Calculator does
The GPA Calculator totals your grade points based on the letter grades you earn and the credits assigned to each class. For unweighted GPA, grades are converted on a 4.0 scale (A = 4.0, B = 3.0, and so on). If you choose weighted mode, the calculator adds a bump for advanced courses — typically +0.5 for Honors and +1.0 for AP/IB — to reflect increased rigor. The result is a quick snapshot of your academic standing you can use for academic planning and applications.
How to use the GPA Calculator
- Select Unweighted (4.0) or Weighted mode depending on your school’s policy.
- Choose the number of decimal places you prefer for the result.
- Enter each course name, the number of credits, and your letter grade.
- If using weighted mode, select Honors or AP/IB for qualifying courses.
- Leave unused rows blank — only filled courses with credits and grades are counted.
- Click Calculate GPA to instantly see your results.
Weighted vs. unweighted GPA: what’s the difference?
An unweighted GPA treats all courses the same and caps at 4.0. A weighted GPA recognizes course difficulty by adding a small bonus to the underlying 4.0 grade points for advanced classes. For example, an A in AP Physics might be worth 5.0 on a 5-point weighted scale, while an A in a regular course remains 4.0. Some schools report both; others only report one. Our GPA Calculator can show unweighted and weighted results to help you understand both views.
Why credits matter
Credits reflect how much a course counts toward your overall GPA. A 4-credit course influences your GPA more than a 1-credit elective. The calculator multiplies each grade’s point value by the course credits to find total grade points, sums them across all classes, and divides by total attempted credits. Be sure to enter the correct credit value used by your school (for example, 3.0 for many college lecture courses or 1.0 for a high school class).
Common grade-to-point conversions (4.0 scale)
- 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
- F = 0.0
Tips to raise your GPA
- Prioritize high-credit courses: small improvements in these classes can have a big impact.
- Target borderline grades: moving from B+ to A- can noticeably boost GPA.
- Use office hours and tutoring: focused help often turns challenging topics into strengths.
- Plan balance: don’t overload on advanced courses at the expense of grades.
- Track progress: recalculate after each exam or assignment to stay on course.
When to use a weighted result
If you’re applying to schools or programs that review course rigor, weighted GPA can tell a more complete story. Many admissions offices consider both your unweighted performance and the difficulty of your schedule. Use the weighted option when your school gives explicit bumps for Honors or AP/IB classes; otherwise, stick with unweighted.
Make data-driven academic decisions
With immediate, transparent calculations, the GPA Calculator helps you forecast outcomes: What happens if you raise a B to an A- in a 4-credit course? How does adding an AP class affect your weighted GPA? Experiment with scenarios, plan your course load, and set realistic goals grounded in the numbers. Whether you’re aiming for dean’s list, athletic eligibility, or scholarship thresholds, our calculator gives you the clarity to succeed.
