GPA Calculator: How to Calculate Your Grade Point Average
Your Grade Point Average (GPA) is one of the most important numbers in your academic career. It affects college admissions, scholarship eligibility, graduate school applications, and even some job offers. Here is exactly how to calculate it and what the numbers mean.
The GPA Scale
The standard U.S. GPA scale converts letter grades to numerical values:
- 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
Some schools use a simpler scale without plus/minus distinctions, where A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0.
How to Calculate GPA Step by Step
GPA is a weighted average, with each course weighted by its credit hours:
- Step 1: Convert each course grade to its point value.
- Step 2: Multiply each point value by the course's credit hours to get quality points.
- Step 3: Add up all quality points.
- Step 4: Divide by the total number of credit hours.
Example:
- English (3 credits, A = 4.0): 3 × 4.0 = 12.0 quality points
- Math (4 credits, B+ = 3.3): 4 × 3.3 = 13.2 quality points
- History (3 credits, A− = 3.7): 3 × 3.7 = 11.1 quality points
- Science (4 credits, B = 3.0): 4 × 3.0 = 12.0 quality points
Total quality points: 12.0 + 13.2 + 11.1 + 12.0 = 48.3
Total credit hours: 3 + 4 + 3 + 4 = 14
GPA: 48.3 / 14 = 3.45
Weighted vs. Unweighted GPA
Unweighted GPA uses the standard 4.0 scale for all classes. An A in regular English and an A in AP English both count as 4.0.
Weighted GPA gives extra points for honors, AP, and IB courses — typically on a 5.0 scale:
- AP/IB courses: Add 1.0 (A = 5.0, B = 4.0, etc.)
- Honors courses: Add 0.5 (A = 4.5, B = 3.5, etc.)
Colleges typically consider both your weighted and unweighted GPA, along with the rigor of your course selections.
What GPA Do You Need?
- Competitive universities: 3.7+ unweighted (Ivy League and top-tier schools)
- Selective universities: 3.3 to 3.7 unweighted
- State universities: 2.5 to 3.3 unweighted (varies by school)
- Graduate school: 3.0+ is generally the minimum; competitive programs want 3.5+
- Scholarships: Many merit scholarships require a minimum of 3.0 to 3.5
