GPA Calculator

Calculate your GPA on a 4.0 scale. Add courses with grades and credit hours for an accurate cumulative GPA. Supports existing GPA for cumulative calculation.

How to Calculate GPA

GPA is calculated by dividing total quality points by total credit hours.

Formula: GPA = Total Quality Points / Total Credit Hours

Where Quality Points = Grade Value × Credit Hours for each course.

Step-by-Step Example

  1. English (A, 3 credits): 4.0 × 3 = 12.0 quality points
  2. Math (B+, 4 credits): 3.3 × 4 = 13.2 quality points
  3. History (A-, 3 credits): 3.7 × 3 = 11.1 quality points
  4. Total: 36.3 quality points / 10 credits = 3.63 GPA

Grade Point Scale

The standard 4.0 scale maps letter grades to numbers:

  • A/A+: 4.0 (Excellent)
  • A-: 3.7
  • B+: 3.3
  • B: 3.0 (Good)
  • B-: 2.7
  • C+: 2.3
  • C: 2.0 (Average)
  • D: 1.0 (Below Average)
  • F: 0.0 (Failing)

Cumulative GPA

To calculate a cumulative GPA across multiple semesters, enter your existing GPA and credit hours in the provided fields. The calculator combines your previous academic record with the new courses you add.

How to Raise Your GPA

  • Focus on high-credit courses — an A in a 4-credit course impacts GPA more than in a 1-credit course
  • Retake courses where your school allows grade replacement
  • Take summer courses to add more A-level credits
  • Use the calculator to model "what if" scenarios for target grades

Frequently Asked Questions

What is a GPA?

GPA (Grade Point Average) is a standardized measure of academic achievement on a 4.0 scale, where A=4.0, B=3.0, C=2.0, D=1.0, and F=0.0.

How do I calculate my GPA?

Multiply each course grade point by its credit hours to get quality points. Sum all quality points, then divide by total credit hours.

What is the difference between weighted and unweighted GPA?

Unweighted GPA uses the standard 4.0 scale. Weighted GPA adds extra points for AP/honors courses (e.g., A in AP = 5.0). This calculator uses the unweighted 4.0 scale.

What GPA do I need for cum laude?

Varies by school. Typical thresholds: cum laude 3.5+, magna cum laude 3.7+, summa cum laude 3.9+.

How do I calculate cumulative GPA?

Enter your existing GPA and total credits in the cumulative section, then add new courses. The calculator combines both.

What is A- or B+ on a 4.0 scale?

A+=4.0, 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, F=0.0.
