GPA Calculator
This GPA calculator computes your weighted or unweighted grade point average from courses, letter grades, and credit hours. Visual scale included.
About GPA Calculator
Tracking your grade point average is important for academic planning, scholarship applications, and graduate school admissions. This GPA calculator lets you add individual courses with their letter grades and credit hours to compute a semester GPA instantly.
Weighted and Unweighted Modes
Switch between weighted and unweighted calculation modes. Weighted mode multiplies each grade by its credit hours, giving higher-credit courses more influence on the final GPA. Unweighted mode treats every course equally, computing a simple average of grade point values regardless of credits.
Dynamic Course Entry
Start with four empty course rows and add or remove courses as needed. For each course, enter an optional course name, select a letter grade from A+ through F, and specify the credit hours. The calculator updates in real time as you make changes.
Visual GPA Scale
A color-coded scale from 0.0 to 4.0 shows exactly where your GPA falls. The visual indicator makes it easy to see your standing at a glance, with color bands ranging from red (below 1.0) through yellow (2.0 range) to green (3.5 and above).
Cumulative GPA Calculation
If you already have a cumulative GPA from prior semesters, enable the optional cumulative GPA section. Enter your existing GPA and total credit hours, and the calculator will merge them with your current courses to produce an updated cumulative figure. This is especially useful for mid-semester planning to see how current grades will affect your overall standing.
Privacy
All grade data stays in your browser. Nothing is saved or sent to any server, so you can freely experiment with hypothetical grades without concern. If you need to work out percentages for individual assignments, the Percentage Calculator is a quick companion tool.
Frequently Asked Questions
How is the weighted GPA calculated?
Each course grade is converted to its grade point value (for example A is 4.0 and B+ is 3.3), then multiplied by that course's credit hours. The weighted GPA is the sum of all quality points divided by the total credit hours. This gives courses with more credits a proportionally larger impact on your GPA.
What is the difference between weighted and unweighted GPA?
A weighted GPA multiplies each grade's point value by the course's credit hours, so a 4-credit A counts more than a 1-credit A. An unweighted GPA treats every course equally regardless of credit hours, simply averaging the grade point values.
What grade scale does this calculator use?
The calculator uses the standard US 4.0 scale with plus and minus modifiers: A+ and 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, and F = 0.0.
Can I calculate my cumulative GPA across multiple semesters?
Yes. Use the optional cumulative GPA section to enter your existing GPA and total credit hours from previous semesters. The calculator will combine those with the current courses to show your updated cumulative GPA.
Does this calculator support A+ grades?
Yes. The calculator includes A+ in the grade dropdown. On the standard 4.0 scale, A+ is treated as 4.0, the same as A. Some institutions award 4.3 for A+, so check with your school if your scale differs.
