Know your GPA in seconds
Your grade point average rolls all of your course grades into a single number that schools, scholarships and employers use to gauge academic performance. Add a row for each class, choose the grade and credit hours, and this calculator works out both your weighted and unweighted GPA on the standard 4.0 scale as you type.
Weighting for Honors and AP
Tougher courses often earn extra credit toward your GPA. Set a class to Honors for a +0.5 bonus or AP/IB for +1.0, and the weighted figure reflects the higher difficulty — an A in an AP class becomes a 5.0. The unweighted figure ignores these bonuses so you can see both views side by side.
How the math works
Each grade becomes grade points (A = 4.0, B = 3.0, and so on), multiplied by the course's credits to give quality points. Add up the quality points across every course and divide by the total credits, and you have your GPA. Because the average is credit-weighted, a strong grade in a four-credit class moves your GPA more than the same grade in a one-credit class.
Frequently asked questions
How is GPA calculated?
Each letter grade is converted to grade points on the 4.0 scale, multiplied by the course's credit hours to get quality points. Your GPA is the total quality points divided by the total credit hours — so higher-credit classes count more.
What's the difference between weighted and unweighted GPA?
Unweighted GPA treats every course the same on a 4.0 scale. Weighted GPA adds a bonus for harder courses — typically +0.5 for Honors and +1.0 for AP or IB — so an A in an AP class can be worth 5.0. This tool shows both.
What grade points does each letter use?
The standard scale: A/A+ = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, and so on down to F = 0.0. These are the values most US schools use.
How many credits should I enter?
Use whatever your school assigns — often 3 or 4 per college course, or 1.0 per year-long high-school class. If every class is worth the same, the exact number doesn't change the GPA, only the weighting between classes does.
