How to use GPA Calculator

- Review the settings and the format notes before continuing.
- Select Calculate, then inspect or copy the result.
Weight each course by its credits
Add a course name, a positive credit value and either a supported letter grade or numeric grade points. The calculator multiplies each grade point value by its credits, sums those quality points and divides by the total credits. This produces a credit-weighted GPA rather than a simple average of letter labels. The editable table lets you add or remove courses without preparing a spreadsheet or writing code.
Use the mapping that fits your institution
The built-in mapping uses A as four, B as three, C as two and common plus/minus increments. A-plus is four or four-point-three according to your setting. Numeric inputs must fit that scale. Institutional policies can treat repeats, withdrawals, pass/fail courses and rounding differently, so include only the courses that should contribute to this calculation. The result is a planning aid rather than an official transcript, and it does not infer transfer-credit rules.
