GPA Calculator on a 4.0 Scale
Grade Point Average summarises academic performance across courses that may carry different credit weights. This GPA calculator lets you enter each course’s credit hours and letter grade, converts letters to the standard 4.0 scale, and computes the term GPA as a credit-weighted average. It is built for students who want a clear number before official transcripts are released or while planning next semester’s load.
Please enter valid credits (>0) for at least one course.
How to Use the GPA Calculator
- Add a row for each course: enter credit hours and select the letter grade.
- Remove any row that was added by mistake so it does not skew the average.
- Calculate to see term GPA based on the weighted average of grade points.
- For a cumulative GPA, add the courses from every term as rows. The tool does not save results.
GPA Calculator Formula Explained
Each letter grade maps to a point value (A = 4.0, A− = 3.7, B+ = 3.3, down to F = 0). Quality points for a course equal points times credit hours. Term GPA equals the sum of quality points divided by the sum of credit hours. Courses with more credits influence the average more than light electives. Pass/fail courses are usually excluded from the GPA calculation unless your school policy says otherwise.
The calculator multiplies each course’s credits by the points for its grade, adds those quality points up and divides by the total credits. The result is shown to two decimal places. The grades are 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 and F 0. There is no A+ or D−. Every row needs credits above zero and a grade, or an error appears.
GPA Calculator Example Calculation
Three courses: 6 credits at A (4.0), 6 credits at B+ (3.3) and 3 credits at B (3.0) produce a credit-weighted term GPA that reflects the heavier modules more than the light one. Always match letter-to-point mappings to your institution’s scale.
Worked example: enter 6 credits with grade A, 6 credits with B+ and 3 credits with B. Quality points are 24 + 19.8 + 9 = 52.8 over 15 credits, so the GPA is 3.52. Enter 4 credits with A−, 3 credits with B− and 3 credits with C+, and the GPA is 2.98.
When to use this tool
Use this for semester planning, exchange applications, and checking progress toward graduation requirements where a 4.0-style scale is used or required for conversion.

GPA Calculator — FAQs
How are plus and minus grades handled?
Standard 4.0 scales assign intermediate values such as A− = 3.7 and B+ = 3.3. Confirm your school’s exact mapping if it differs.
Do repeated courses replace the old grade?
Policy varies. Some schools replace; others average both attempts. This calculator uses only the grades you enter.
Is a 4.0 always the maximum?
Most US-style scales cap at 4.0. A few institutions allow A+ above 4.0; adjust manually if that applies to you.
Can I calculate cumulative GPA?
Yes by including all courses across terms, or by combining prior quality points and credits with the new term’s results.
