You enter each course, select a letter grade, and enter the number of credit hours. The calculator multiplies the grade points by the credit hours for each course, adds them all up, and divides by the total credit hours. The result is your weighted GPA on a 4.0 scale.

No. All calculations happen locally in your browser. Nothing you enter is sent to any server or stored anywhere. Once you close or refresh the page, the data is gone.

The calculator uses the standard US 4.0 grade scale, which is the most common. If your school uses a different scale (for example, some schools give A+ a value of 4.3), the result may differ slightly from your official GPA. Always check with your school's registrar for your official GPA.

A 4-credit course has more weight than a 1-credit course. If you get an A in a 4-credit class, it affects your GPA much more than an A in a 1-credit class. Weighting by credit hours gives a more accurate picture of your overall academic performance.
