GPA Calculator — FAQ
Answers to the most frequently asked questions about GPA calculation, grading scales, and using our online GPA calculators.
1. How is weighted GPA calculated?
A weighted GPA gives extra points for advanced courses such as Honors, AP (Advanced Placement), or IB (International Baccalaureate). On a standard 4.0 scale, an A in a Regular course is worth 4.0, while an A in an Honors course may be worth 4.5, and an A in an AP/IB course may be worth 5.0. The weighted GPA is calculated the same way as an unweighted GPA — total grade points divided by total credits — but each grade point includes the course-level bonus before averaging.
2. What is a 3.5 GPA in percentage?
A 3.5 GPA on a 4.0 scale roughly corresponds to approximately 87–89% as an illustrative estimate. However, GPA-to-percentage conversion is not standardized and varies by school and institution. Some schools may treat 3.5 as equivalent to 85%, while others may consider it 90%. Always check with your specific institution for their official conversion policy.
3. How do I calculate my GPA on a 4.0 scale?
To calculate your GPA: (1) Convert each letter grade to its grade point value (A=4.0, A-=3.7, B+=3.3, B=3.0, etc.). (2) Multiply each grade point by the number of credit hours for that course. (3) Sum all the results from step 2. (4) Divide that sum by the total number of credit hours. The result is your GPA.
4. What is the difference between weighted and unweighted GPA?
An unweighted GPA uses a standard 4.0 scale where all courses are treated equally regardless of difficulty. A weighted GPA adds extra points for advanced coursework — typically +0.5 for Honors courses and +1.0 for AP/IB courses. This means a student taking challenging courses can have a GPA above 4.0 on a weighted scale.
5. What is a good GPA?
What constitutes a 'good' GPA depends on context. Generally, a 3.5–4.0 is considered excellent and competitive for top colleges and graduate programs. A 3.0–3.4 is good and above average. A 2.5–2.9 is average. These are general guidelines — different institutions, programs, and employers may have different expectations.
6. How many credit hours are typical per course?
Most college courses are worth 3 or 4 credit hours each. Lab courses may be 1–2 credits. High school courses are typically 1 credit per year-long course or 0.5 credits per semester course. You should enter the actual credit hours as listed in your transcript or course catalog for the most accurate GPA calculation.
7. Can I calculate my GPA for multiple semesters?
Yes. Use our College GPA Calculator to enter courses across multiple terms or semesters. The calculator shows both your per-term GPA and your cumulative overall GPA across all entered terms, weighted by credit hours.
