How GPA Is Calculated

GPA is the credit-weighted average of your grade points. Each letter grade maps to a number on a 4.0 scale (A = 4.0, B = 3.0, etc.). Multiply each grade point by the course's credit hours, sum those products and divide by the total credit hours. This gives you a single number that represents your overall academic performance across different courses and credit loads.

Using the GPA Calculator

1
Add your courses

Create a row for each course you are including in the calculation.

2
Enter the credit hours

Type the number of credits each course is worth, typically between 1 and 5.

3
Select your letter grade

Choose the letter grade you earned or expect to earn in each course (A, A-, B+, etc.).

4
View your GPA

The tool instantly computes your semester GPA. Add prior cumulative data to see your overall GPA.

Semester vs. Cumulative GPA

A semester GPA covers only the courses taken in a single term. A cumulative GPA includes every course across all completed terms. To compute cumulative GPA, enter your prior GPA and total credits in the cumulative section, then add the current semester's courses. The calculator combines both sets of data to give you an up-to-date cumulative average.

Common GPA Scales

  • 4.0 scale (standard US): A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0
  • 4.0 scale with plus/minus: A+ = 4.0, A = 4.0, A- = 3.7, B+ = 3.3 and so on
  • Percentage-based systems can be converted by mapping ranges to letter grades
  • Some institutions use a 5.0 or 10.0 scale; convert to 4.0 before using this tool

Frequently Asked Questions

Does this calculator support plus and minus grades?
Yes. You can select A+, A, A-, B+, B, B- and so on. Each grade maps to its standard value on the 4.0 scale (for example, B+ = 3.3, B- = 2.7).
How do I calculate cumulative GPA with transfer credits?
Enter your transfer GPA and transfer credit hours in the cumulative section. The calculator will combine them with your current semester courses to produce an updated cumulative GPA.
Can I use this for graduate-level courses?
Absolutely. The GPA formula is the same regardless of level. Just make sure the credit hours match what your institution assigns to each graduate course.
