A GPA calculator converts your letter grades and credit hours into a grade point average on the standard 4.0 scale used by most US colleges and high schools. Enter one course per line with its grade and credits, and the calculator returns your term GPA, total credits, and total grade points earned.
If you already have a cumulative GPA from previous semesters, add it along with your completed credits to see your updated cumulative GPA after this term. This makes it easy to answer the classic question: "What grades do I need this semester to reach my target GPA?" Try different grade scenarios and watch the result change.
How GPA Is Calculated
GPA is a credit-weighted average of grade points:
GPA = Total Grade Points ÷ Total Credits
Each letter grade maps to a point value on the 4.0 scale: A+/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, F = 0.0.
Multiply each course’s point value by its credit hours to get grade points, sum them across all courses, then divide by total credits. A 4-credit course therefore influences your GPA one-third more than a 3-credit course with the same grade — which is why protecting grades in high-credit courses matters most.
Weighted vs. Unweighted GPA
This calculator uses the unweighted 4.0 scale, where an A is 4.0 regardless of course difficulty. Many high schools also report a weighted GPA that rewards harder classes:
- Standard course: A = 4.0 (unweighted)
- Honors course: often A = 4.5 (0.5 bonus)
- AP / IB / dual enrollment: often A = 5.0 (1.0 bonus)
Colleges typically recalculate applicants’ GPAs using their own method, so the unweighted figure is the most portable number to know. Useful benchmarks: 3.5+ is generally considered strong for competitive college admissions, 3.0 is a common cutoff for scholarships and internships, and 2.0 is the usual minimum to stay in good academic standing.
Example: A Four-Course Semester
Suppose a student takes Biology (A-, 3 credits), Calculus I (B+, 4 credits), English Composition (A, 3 credits), and Psychology 101 (B, 3 credits).
Grade points: Biology 3.7 × 3 = 11.1; Calculus 3.3 × 4 = 13.2; English 4.0 × 3 = 12.0; Psychology 3.0 × 3 = 9.0. Total = 45.3 grade points over 13 credits.
GPA = 45.3 ÷ 13 = 3.48.
If the student came in with a 3.20 cumulative GPA over 45 credits (144 grade points), the new cumulative GPA is (144 + 45.3) ÷ (45 + 13) = 189.3 ÷ 58 = 3.26 — a solid one-term improvement.
Frequently Asked Questions
What is a good GPA?
A GPA of 3.0 (B average) is generally considered good, 3.5+ is strong, and 3.7+ is excellent. For competitive graduate programs and top employers, 3.5 or higher stands out. Context matters: a 3.4 in a demanding engineering program can be more impressive than a 3.8 in an easier course load.
How do I calculate my GPA by hand?
Convert each letter grade to points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0, with +/- adding or subtracting 0.3), multiply each by the course’s credit hours, add up all the grade points, then divide by total credits. For example, an A in a 3-credit class earns 12.0 grade points.
What is the difference between term GPA and cumulative GPA?
Term (or semester) GPA covers only the courses from one term, while cumulative GPA averages every credit you have ever taken. Cumulative GPA moves slowly: the more credits you accumulate, the less any single semester can shift it, which is why early semesters have outsized impact.
Do pass/fail classes affect GPA?
At most schools, no. A "Pass" earns credit toward graduation but carries no grade points, so it is excluded from the GPA calculation. A "Fail," however, often counts as an F (0.0) and does lower your GPA. Check your school’s specific policy before electing pass/fail.
Can I raise a 2.5 GPA to a 3.0?
Yes, but the math depends on credits completed. With 30 credits at 2.5, you would need 30 more credits at a 3.5 average to reach exactly 3.0. With 90 credits already done, you would need 30 credits of straight 4.0 work to get to about 2.9 — so start improving as early as possible.
