About the GPA Calculator
Tezmy's GPA Calculator works out your grade point average from your letter grades and each course's credit hours, on the 4.0 scale used by most US colleges and high schools. Add as many courses as you need, and optionally enter your current GPA and credits so far to see how this semester changes your cumulative GPA. It's a quick way to check where you stand, plan the grades you need, or prepare scholarship and graduate school applications.

How GPA is calculated
Each letter grade is worth a number of grade points. Multiply each course's grade points by its credit hours, add these together, then divide by the total credit hours. For example, an A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course give (12 + 12) ÷ 7 = 3.43.
The 4.0 grade scale used here
This is the most common US college scale. Some schools give A+ a 4.3 or don't use minus grades, so check your school's catalogue if your numbers differ slightly.
- A+ and 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. D−: 0.7.
- F: 0.
Semester GPA vs cumulative GPA
Your semester GPA covers only this term's courses. Your cumulative GPA covers everything so far. To see your new cumulative GPA, enter your current GPA and the credits you have already completed, then add this semester's courses: past credits and new credits are combined correctly, so a strong semester lifts your overall GPA in proportion to its credits.
Tip: courses with more credits move your GPA the most, so they're the ones to focus on when you're aiming for a target.
Weighted, pass/fail and international grades
Weighted GPAs (extra points for honours or AP classes) and school-specific scales vary a lot, so this calculator uses the standard unweighted 4.0 scale. Pass/fail and withdrawn courses usually don't count towards GPA at all, so leave them out. If your country uses percentages or a 10-point scale, use the Percentage Calculator or Average Calculator instead, or check how your university converts grades. To turn the result into a percent, use CGPA & GPA to Percentage, and for a single class use the Percentage Calculator.

Frequently asked questions
How is GPA calculated?
Each grade is turned into points (A = 4.0, B = 3.0 and so on), multiplied by the course's credits, added up, then divided by the total credits.
How do I calculate my cumulative GPA?
Enter your current GPA and how many credits it covers. The calculator combines them with this semester's grades, weighting each by credits.
Is an A+ worth more than 4.0?
At most schools an A+ counts as 4.0, the same as an A. Some schools use 4.3; check your school's policy.
What about pass/fail or withdrawn courses?
Leave them out. Pass/fail and withdrawn courses usually don't count towards your GPA.
Does it handle weighted (honors/AP) GPA?
Not yet. This calculator uses the unweighted 4.0 scale.
What is a good GPA?
On a 4.0 scale, 3.0 (a B average) is generally considered good, 3.5 and above is very good, and many scholarships and competitive programmes look for 3.5 or higher. Requirements vary by school.
How many credits is a typical course?
Most US college courses are 3 or 4 credit hours; labs may be 1. Your transcript or course catalogue shows the exact number.
Can I raise my GPA in one semester?
Yes, but the effect gets smaller as your total credits grow. Enter your current GPA and credits with the grades you hope to get to see exactly what's possible.
