GPA Calculator
Calculate your Grade Point Average on the standard 4.0 scale.
How to Calculate Your GPA
Your Grade Point Average (GPA) is a number that summarizes your academic performance across all courses. Most US schools use a 4.0 scale, where each letter grade is assigned a point value and weighted by the number of credit hours for each course.
GPA Formula
GPA = Total Grade Points ÷ Total Credit Hours
Where Grade Points for each course = Grade Point Value × Credit Hours. Sum the grade points across all courses, then divide by the total credits.
Standard 4.0 GPA Scale
- A = 4.0 — Excellent
- A− = 3.7 — Excellent
- B+ = 3.3 — Good
- B = 3.0 — Good
- B− = 2.7 — Above Average
- C+ = 2.3 — Average
- C = 2.0 — Average
- C− = 1.7 — Below Average
- D+ = 1.3 — Passing
- D = 1.0 — Barely Passing
- F = 0.0 — Failing
Example Calculation
Say you took three courses: Math (A, 3 credits), English (B, 4 credits), and History (C, 3 credits). Your grade points are: 4.0×3 = 12, 3.0×4 = 12, 2.0×3 = 6. Total grade points = 30, total credits = 10. GPA = 30 ÷ 10 = 3.00.
How Credit Hours Affect Your GPA
Credit hours act as a weight for each course. A 4-credit course has twice the impact on your GPA as a 2-credit course with the same grade. This means a strong grade in a high-credit course can significantly boost your GPA, while a poor grade in the same course can drag it down just as fast. For example, an A in a 4-credit lab course contributes 16 grade points, while an A in a 2-credit seminar contributes only 8. When planning your semester, be aware that your performance in higher-credit courses matters more. If you are trying to raise your GPA, focus your effort on the courses worth the most credits rather than spreading attention evenly across all classes.
Term GPA vs. Cumulative GPA
Term GPA reflects your performance in a single semester, while cumulative GPA includes every course you have taken across all semesters. Both use the same formula, but cumulative GPA gives a broader picture of your academic record. To calculate your cumulative GPA with this tool, enter all courses from all terms in the calculator. Keep in mind that cumulative GPA changes slowly once you have many credits — a strong semester can lift a low cumulative GPA, but the effect is smaller the further along you are. If you are early in your academic career, each semester has a larger impact, so strong performance now pays off more than trying to recover later.
How to Raise Your GPA
Raising your GPA requires earning grades above your current average, weighted by credit hours. The higher your current GPA and the more credits you have completed, the harder it is to move the number. A student with a 2.5 GPA and 30 credits can reach a 3.0 by averaging a 3.5 over the next 30 credits — a challenging but achievable goal. However, a student with a 2.5 GPA and 90 credits would need to average closer to a 4.0 over the next 30 credits just to reach a 2.9. This is why early grades matter so much. If you are trying to recover, prioritize high-credit courses, consider retaking courses where your school allows grade replacement, and seek academic support early rather than waiting until finals.
Different GPA Scales Explained
This calculator uses the standard unweighted 4.0 scale, where an A equals 4.0 regardless of course difficulty. Some schools use a weighted scale that gives extra points for honors, AP, or IB courses — for example, an A in an AP class might be worth 5.0. Weighted GPAs can exceed 4.0, which is why some students report a GPA of 4.3 or higher. If your school uses a weighted scale, you can still use this calculator by entering the weighted point values as letter grades, but the results will not reflect your school's official calculation. For graduate school applications and most official purposes, the unweighted 4.0 scale is the standard reference, which is what this tool provides.
What Is a Good GPA?
Context matters when evaluating your GPA. A 3.0 (B average) is generally considered the baseline for "good" academic standing and is a common minimum for graduate program admissions. A 3.5 or above is viewed as very good, while a 3.7+ is excellent and competitive for selective programs. However, what counts as good depends on your goals: some employers care little about GPA, while competitive graduate programs may expect a 3.5 or higher. If you are aiming for a specific program, check its published minimum requirements and average admitted GPA. Use this calculator to track your progress each semester and project what grades you need to reach your target.
Frequently Asked Questions
On a 4.0 scale, a GPA of 3.0 or higher (B average) is generally considered good. A 3.5 or above is very good, and a 3.7+ is excellent. Many graduate programs require a minimum 3.0 GPA for admission.
Credit hours weight each course by its importance. A 4-credit course has twice the impact on your GPA as a 2-credit course. Grade points are calculated by multiplying the grade value by the credits, then the total is divided by total credits.
Yes. This calculator uses the standard US scale including A−, B+, B−, C+, C−, D+, and D. Each has its own point value as defined by the 4.0 grading scale.
Term GPA covers only the courses taken in a single semester. Cumulative GPA includes all courses taken across all semesters. To calculate cumulative GPA, enter all courses from all terms in the calculator.
