What is a GPA Calculator?
The GPA Calculator helps you calculate your grade point average on a 4.0 scale by entering course grades and credit hours. Just enter your numbers and the tool does the rest — no manual math, no guesswork.
How to calculate GPA manually (the formula)
The specific formula depends on what you are calculating. The calculator applies the correct equation automatically, but understanding the formula helps you verify the results and adapt them to your own needs.
Example calculation
Enter your values into the calculator and it will produce an instant result. For a step-by-step walkthrough, try different inputs and observe how each one affects the outcome.
Common mistakes
- Forgetting to enter credit hours — GPA is credit-weighted. A 3-credit A affects GPA more than a 1-credit A.
- Using the wrong grade mapping — Some schools use plus/minus differently. Check your school’s specific scale.
- Mixing semester and cumulative GPA — Semester GPA uses only current courses. Cumulative includes all previous coursework.
Frequently asked questions
How does a GPA calculator work?
It converts each letter grade to its numeric value (A=4.0, B=3.0, etc.), multiplies by credit hours, and divides the total points by total credits.
How do I check my GPA?
Enter each course’s grade and credit hours. The calculator sums the grade points and divides by total credits to give your GPA.
How is GPA calculated on a 4.0 scale?
Each grade maps to a number (A=4.0, A-=3.7, B+=3.3, etc.). Multiply each by its credit hours, sum, and divide by total hours.
What letter grades correspond to each GPA point?
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.
Can I calculate my GPA for one semester?
Yes. Enter only the courses from that semester to get your semester GPA. Include all courses for your cumulative GPA.
What is the difference between weighted and unweighted GPA?
Unweighted uses the 4.0 scale for all courses. Weighted adds extra points (up to 5.0) for honors or AP classes.
