Convert letter grades to GPA (Grade Point Average) on the 4.0 scale. Supports all letter grade variations including plus (+) and minus (-) grades.
• A grades = 3.7-4.0 GPA
• B grades = 2.7-3.3 GPA
• C grades = 1.7-2.3 GPA
• D grades = 0.7-1.3 GPA
• F grade = 0.0 GPA

| Letter Grade | GPA Points | Percentage | Quality |
|---|---|---|---|
| A+ / A | 4.0 | 93-100% | Excellent |
| A- | 3.7 | 90-92% | Excellent |
| B+ | 3.3 | 87-89% | Good |
| B | 3.0 | 83-86% | Good |
| B- | 2.7 | 80-82% | Good |
| C+ | 2.3 | 77-79% | Satisfactory |
| C | 2.0 | 73-76% | Satisfactory |
| C- | 1.7 | 70-72% | Satisfactory |
| D+ | 1.3 | 67-69% | Poor |
| D | 1.0 | 63-66% | Poor |
| D- | 0.7 | 60-62% | Poor |
| F | 0.0 | 0-59% | Failing |
The standard 4.0 GPA scale assigns specific point values to each letter grade. The scale provides a numeric representation of academic performance that can be easily averaged and compared across different courses and students.
• A+/A = 4.0 points
• A- = 3.7 points
• B+ = 3.3 points
• B = 3.0 points
• B- = 2.7 points
• C+ = 2.3 points
• C = 2.0 points
• C- = 1.7 points
• D+ = 1.3 points
• D = 1.0 point
• D- = 0.7 points
• F = 0.0 points
To calculate your overall GPA from multiple letter grades:
Math (3 credits): A = 4.0 × 3 = 12.0 points
English (3 credits): B+ = 3.3 × 3 = 9.9 points
History (3 credits): A- = 3.7 × 3 = 11.1 points
Total: 33.0 points ÷ 9 credits = 3.67 GPA
While this calculator uses the most common 4.0 scale, some schools may use different point values for letter grades. Always verify your school's specific grading scale for the most accurate GPA calculation.
On the standard unweighted 4.0 scale, both A+ and A are worth 4.0 GPA points. However, some schools use weighted scales or 4.3 scales where A+ may be worth more (4.3 or higher). Check your school's specific policy.
A 3.5 GPA falls between A- (3.7) and B+ (3.3), so it's typically considered a high B+ or low A-. It represents excellent academic performance and is competitive for most colleges.
No, while most schools follow similar patterns, the exact point values can vary. Some schools don't use plus/minus grades, some use different cutoffs for letter grades, and others use weighted scales for honors or AP courses.
On the standard 4.0 scale, a B+ converts to 3.3 GPA points. This represents good, above-average academic performance and typically corresponds to 87-89% percentage grades.
Unweighted GPA uses the standard 4.0 scale for all courses. Weighted GPA gives extra points (often 0.5 or 1.0) for advanced courses like honors, AP, or IB classes, allowing GPAs to exceed 4.0.
No, an A- is worth 3.7 on the standard scale. To achieve a 4.0 GPA, you need all A's or A+'s in all your courses. Even one A- will lower your overall GPA below 4.0.
Generally, a 2.0 GPA (C average) is considered passing in most high schools and colleges. However, some programs or scholarships may require higher GPAs to maintain good standing.
The impact depends on how many courses you've taken. In your first semester, each grade has a large impact. Later in your academic career, individual grades have less effect on your cumulative GPA due to averaging over more courses.
Letter grades have been used in American education since the late 1800s. The system provides a qualitative assessment of student performance, with A representing excellent work and F representing failing work. The addition of plus (+) and minus (-) modifiers in the mid-20th century added more granularity to the grading system.
When converted to the 4.0 GPA scale, letter grades become quantifiable numbers that can be averaged and compared. This standardization allows colleges to evaluate students from different high schools fairly and helps students track their academic progress over time.
