GPA Calculator
Calculate your semester and cumulative GPA. Add courses with grades and credit hours, or plan what grades you need to reach your target GPA.
How GPA is Calculated
GPA (Grade Point Average) measures academic performance on a standardized scale. Most US colleges use a 4.0 scale where each letter grade has a numeric value. Your GPA is the weighted average of these values, weighted by the number of credit hours for each course.
The GPA Formula
"Quality Points" for each course = Grade Value × Credits
English (A, 3 credits): 4.0 × 3 = 12.0 quality points
Math (B+, 4 credits): 3.3 × 4 = 13.2 quality points
History (A-, 3 credits): 3.7 × 3 = 11.1 quality points
Science (B, 3 credits): 3.0 × 3 = 9.0 quality points
Total: 45.3 ÷ 13 credits = 3.48 GPA
Grade Point Values (4.0 Scale)
| Letter | GPA Value | Percentage (typical) |
|---|---|---|
| A | 4.0 | 93–100% |
| A- | 3.7 | 90–92% |
| B+ | 3.3 | 87–89% |
| B | 3.0 | 83–86% |
| B- | 2.7 | 80–82% |
| C+ | 2.3 | 77–79% |
| C | 2.0 | 73–76% |
| C- | 1.7 | 70–72% |
| D+ | 1.3 | 67–69% |
| D | 1.0 | 60–66% |
| F | 0.0 | Below 60% |
Semester vs. Cumulative GPA
Your semester GPA covers only the current term's courses. Your cumulative GPA is the weighted average across all semesters. To compute cumulative GPA, add the new semester's quality points and credits to your existing totals and recalculate. This calculator handles both — enter your previous cumulative GPA and credits in the optional section to see the combined result.
Using the GPA Planner
The Planner tab helps you figure out what grades you need to reach a target GPA. Enter your current cumulative GPA, credits completed, your target, and how many credits you plan to take. The tool calculates the minimum GPA you need to average in your upcoming courses. If the required GPA exceeds 4.0, the target isn't achievable in that number of credits — you'll need more semesters.
Frequently Asked Questions
Multiply each course's grade points by its credit hours to get quality points. Sum all quality points and divide by total credit hours. Example: A (4.0) in 3 credits = 12 points. B (3.0) in 4 credits = 12 points. Total = 24 ÷ 7 = 3.43 GPA.
The standard US scale: 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. Some schools don't use +/- grades.
Semester GPA covers one term. Cumulative GPA includes all terms. Enter your previous cumulative GPA and credits in the optional section to calculate the new combined GPA.
Use the GPA Planner tab. Enter your current GPA, credits, target GPA, and planned credits. It tells you what average grade you need in upcoming courses. The more credits you have, the harder it is to move your cumulative GPA.
Most US colleges use the 4.0 scale, but some don't use +/- grades. Some high schools use a 5.0 weighted scale for AP/honors. International systems vary widely. This calculator uses the standard US 4.0 scale.
Typically no. Pass/fail and audit courses usually don't count toward GPA, though they may count toward credit hours at some schools. Only letter-graded courses are included in this calculator.
