GPA Calculator
Enter each course letter grade and its credit hours — ExamTally returns your grade point average on the 4.0 scale, weighted by credits.
GPA is the credit-weighted average of your grade points (A=4, B=3, C=2, D=1, F=0). An A in a 3-credit course and a B in a 4-credit course give (4·3 + 3·4) ÷ 7 = 24 ÷ 7 = 3.43. Enter your own courses below.
Key takeaways
- GPA = Σ(grade points × credits) ÷ Σcredits.
- Grade points: A=4, B=3, C=2, D=1, F=0.
- Credits weight each course — a 4-credit grade outweighs a 1-credit one.
- A/3cr + B/4cr → 24 ÷ 7 = 3.43.
- Honors/AP bonuses? Use the weighted GPA calculator instead.
How GPA is calculated
GPA converts every letter grade into grade points, then takes a credit-weighted average. Each course's points are multiplied by its credit hours to get "quality points." Add all the quality points and divide by the total number of credits — courses worth more credits count proportionally more.
Because the denominator is the total credits, the result always lands between 0.0 and 4.0 on this scale. The calculator waits until the total credits exceed zero, so there is no dividing by zero, and blank rows are simply skipped.
Worked example: two courses
Say you earned an A in a 3-credit class and a B in a 4-credit class. The A is worth 4 points × 3 credits = 12 quality points; the B is 3 points × 4 credits = 12 quality points. Together that's 24 quality points across 3 + 4 = 7 credits. Divide: 24 ÷ 7 = 3.43. Even though both courses contributed 12 quality points, the heavier B course keeps the GPA below 3.5.
Letter grade → GPA points
| Letter | Percentage | GPA points (4.0) |
|---|---|---|
| A | 90–100% | 4.0 |
| B | 80–89% | 3.0 |
| C | 70–79% | 2.0 |
| D | 60–69% | 1.0 |
| F | Below 60% | 0.0 |
This is the standard unweighted 4.0 scale. Schools that use plus/minus grades assign intermediate points (A− = 3.7, B+ = 3.3) — always confirm yours.
For the extra weight given to Honors and AP courses, use the weighted GPA calculator. To roll several semesters into one cumulative figure, use the high school GPA calculator.
Frequently asked questions
How is GPA calculated?
Convert each letter grade to grade points (A=4, B=3, C=2, D=1, F=0), multiply by the course credit hours, add up those quality points, then divide by the total credits. An A in 3 credits and a B in 4 credits is (4×3 + 3×4) ÷ 7 = 24 ÷ 7 = 3.43.
What is the 4.0 GPA scale?
On the standard unweighted 4.0 scale, A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0. Some schools add pluses and minuses (A− = 3.7, B+ = 3.3, and so on); this calculator uses whole-letter points, which is the most common base scale.
Why do credit hours matter?
Credits weight each course. A grade in a 4-credit class counts more toward your GPA than the same grade in a 1-credit class. That is why GPA divides total quality points by total credits rather than simply averaging the letters.
What about Honors and AP classes?
A plain GPA treats every course on the same 4.0 scale. To add the extra points many schools give for Honors (+0.5) or AP (+1.0) courses, use the weighted GPA calculator, which can push a GPA above 4.0.
Can I leave some courses blank?
Yes. Rows with no credits are ignored, so you can fill in only the courses you have. As long as the total credits are above zero the calculator returns a GPA; otherwise it waits for input.
How many decimal places is GPA shown to?
GPA is shown to two decimal places — the convention on most transcripts (for example 3.43). Your school may truncate instead of round, so treat the figure as an estimate and confirm against your official record.
GPA is mathematical: the sum of each course's grade points times its credits, divided by total credits. Grade points use the standard unweighted 4.0 scale (A=4, B=3, C=2, D=1, F=0); schools set their own plus/minus point values and rounding rules.
