The GPA calculator converts your letter grades into a grade point average. Enter your grades and credit hours for each course to get your semester GPA or cumulative GPA. It handles both weighted and unweighted scales.
How GPA Is Calculated
GPA is the average of your grade points, weighted by course credit hours. Multiply each course grade point by its credit hours, add the totals, then divide by the total credit hours taken. Courses with more credits have a greater impact on your GPA.
GPA = Sum of (Grade Points x Credit Hours) / Total Credit Hours
Example: A (4.0) in a 3-credit course + B (3.0) in a 4-credit course = (12 + 12) / 7 = 3.43 GPA.
Letter Grade to GPA Conversion Table
| Letter Grade | Percentage | GPA Points (4.0 scale) |
|---|---|---|
| A+ | 97-100% | 4.0 |
| A | 93-96% | 4.0 |
| A- | 90-92% | 3.7 |
| B+ | 87-89% | 3.3 |
| B | 83-86% | 3.0 |
| B- | 80-82% | 2.7 |
| C+ | 77-79% | 2.3 |
| C | 73-76% | 2.0 |
| C- | 70-72% | 1.7 |
| D+ | 67-69% | 1.3 |
| D | 63-66% | 1.0 |
| D- | 60-62% | 0.7 |
| F | Below 60% | 0.0 |
Semester GPA vs. Cumulative GPA
Semester GPA covers only the current term. Cumulative GPA covers all terms combined. To calculate cumulative GPA, add the quality points from all semesters and divide by all credit hours attempted. One bad semester hurts your cumulative GPA less when you have completed many credits.
High School vs. College GPA
| Factor | High School | College |
|---|---|---|
| Scale | 4.0 (unweighted) or 5.0 (weighted) | 4.0 (standard) |
| Weighted courses | AP/IB add +0.5 to +1.0 per course | Rarely weighted |
| Credit hours | Usually equal per subject | Varies by course (1-4 credits) |
| Pass/fail option | Rarely available | Common for electives |
| Transcript format | Class rank often included | GPA only |
Worked Example: Semester GPA Calculation
Student has four courses: Biology (A, 4 credits), English (B+, 3 credits), Math (A-, 3 credits), History (B, 3 credits). Quality points: (4.0x4) + (3.3x3) + (3.7x3) + (3.0x3) = 16 + 9.9 + 11.1 + 9 = 46. Total credits: 4+3+3+3 = 13. Semester GPA: 46 / 13 = 3.54.
Frequently Asked Questions
What is a good GPA?⌄
In high school, a 3.5 GPA (B+/A- average) is competitive for selective colleges. A 3.0 (B average) meets most admissions requirements. In college, a 3.0 GPA is generally considered satisfactory. Many graduate programs require a 3.0 minimum, and competitive programs want 3.5 or higher.
How do I raise my GPA?⌄
Focus on courses with the most credit hours, since they have the biggest impact. Retake failed courses if your school allows grade replacement. Avoid withdrawing late (W grades can hurt). Take easier electives alongside hard courses to balance your term.
Does AP or IB class weigh my GPA?⌄
In high school, AP and IB classes often add a 0.5 to 1.0 bonus on a weighted GPA scale, turning a B (3.0) into a 3.5 or 4.0. This is only on the weighted scale. Most colleges recalculate your GPA on an unweighted 4.0 scale when reviewing applications.
What GPA do you need to get into college?⌄
It depends on the school. Ivy League and top universities typically want 3.9+ unweighted GPA. State universities commonly accept 2.5-3.5. Community colleges often have open admissions with no GPA requirement.
How many credit hours do I need to raise my GPA by 0.1?⌄
It depends on your current GPA and total credits earned. The more credits you have, the harder it is to move your cumulative GPA. A student with 30 credits and a 2.5 GPA needs about 15 credit hours of straight A grades to push the GPA to 3.0.
