GPA Calculator: Calculate Your Grade Point Average Fast
Calculate semester GPA, cumulative GPA, and what grades you need to hit your target GPA. Works with 4.0, 4.3, and custom grading scales.
Semester grades just posted and you want to know where you stand — or you need to figure out what you have to score on finals to keep your scholarship. Either way, the CalcHub GPA Calculator handles the math without making you look up the formula.
The 4.0 Scale: Standard Grade Conversions
Most US colleges use a 4.0 scale. Here are the standard conversions, though some schools vary slightly:
| Letter Grade | Grade Points | Percentage (typical) |
|---|---|---|
| A+ | 4.0 (some schools: 4.3) | 97–100% |
| A | 4.0 | 93–96% |
| 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% |
How GPA Is Calculated
GPA isn't a simple average of grade points — it's a weighted average based on credit hours. A 4-credit course counts twice as heavily as a 2-credit course.
Formula:GPA = Sum(Grade Points × Credit Hours) / Sum(Credit Hours)| Course | Credits | Grade | Points |
|---|---|---|---|
| Calculus II | 4 | B+ (3.3) | 13.2 |
| History 101 | 3 | A (4.0) | 12.0 |
| English Comp | 3 | B (3.0) | 9.0 |
| Chemistry | 4 | C+ (2.3) | 9.2 |
| Totals | 14 | 43.4 |
Semester GPA vs. Cumulative GPA
Your semester GPA is just for that term. Your cumulative GPA (the one on your transcript, the one grad schools see) combines all semesters by pooling total quality points and total credit hours.
If last semester was rough, one good semester won't fix a low cumulative GPA as quickly as you'd hope. The calculator has a "cumulative" mode where you enter your current total quality points and credit hours, add your new semester's courses, and see the updated cumulative GPA.
What Do I Need to Hit My Target GPA?
This is the feature students use most. Say you need a 3.5 cumulative GPA to keep your scholarship, but you're currently sitting at 3.38 with 45 credit hours completed. You're taking 15 credits this semester. What GPA do you need this term?
The calculator solves this:
- Current quality points: 3.38 × 45 = 152.1
- After this semester: (152.1 + new quality points) / 60 = 3.5
- New quality points needed: 3.5 × 60 − 152.1 = 57.9
- Required semester GPA: 57.9 / 15 = 3.86
So you'd need roughly an A/A− average this semester. Doable, but you'd need to know that going in — not after finals.
Plus/Minus Grading: Does Your School Use 4.3?
Some schools award a 4.3 for A+ grades. Most don't — they cap at 4.0 regardless of A+. Check your school's policy. If your school uses the 4.3 scale, the calculator has a toggle for this.
Does a W grade hurt my GPA?
Withdrawals (W) generally don't affect GPA — they just appear on your transcript. A WF (withdraw failing) at some schools does count as an F in GPA calculations. Always check your school's specific policy before withdrawing late in a semester.
I'm in a graduate program — does the calculation change?
The math is the same, but grad programs often have higher minimum GPA requirements (3.0 to remain in good standing, 3.5+ for funding eligibility). Some grad programs don't award grades below a B, meaning a C effectively functions as a failing grade. Enter your actual grade points as awarded by your institution.
How do I calculate my GPA if I transferred schools?
Most colleges recalculate GPA using only courses taken at that institution — transfer credits may count toward your degree requirements but don't factor into your campus GPA. Some schools calculate a combined GPA. Check with your registrar.
