How to Use the GPA Calculator
- 1. List your courses. Each row is one course: pick the letter grade from A+ down to F and type the credit hours (half credits such as 1.5 are fine). Add rows for more courses; the course name is optional and only helps you keep track.
- 2. Read the semester GPA. The three cards show your semester GPA, total credits and total grade points, and they update as you type.
- 3. Add your history (optional). Type your current GPA and the credits it covers under Cumulative GPA. The calculator treats them as one more block of grade points and shows the combined GPA and credit total.
- 4. Check the scale. The reference table at the bottom lists the grade points the calculator uses. If your school's scale differs, see below before you trust the number.
How GPA Is Calculated
GPA is a credit-weighted average. Each course contributes its credit hours multiplied by the grade points of the letter grade, and the total is divided by the total credits:
GPA = Σ(credits × grade points) ÷ Σ credits
A (4.0) in a 3-credit course: 3 × 4.0 = 12.0
B+ (3.3) in a 4-credit course: 4 × 3.3 = 13.2
A- (3.7) in a 3-credit course: 3 × 3.7 = 11.1
B (3.0) in a 3-credit course: 3 × 3.0 = 9.0
Total grade points = 45.3; total credits = 13; semester GPA = 45.3 ÷ 13 = 3.48
Now suppose you arrive with a 3.40 GPA over 60 credits. That is 3.40 × 60 = 204.0 grade points. Add this semester and the cumulative GPA is (204.0 + 45.3) ÷ (60 + 13) = 249.3 ÷ 73 = 3.42. Credits do the weighting: a 4-credit B+ moves the result more than a 1-credit A.
The Scale This Calculator Uses — and Where Schools Differ
| Letter | Grade points | Letter | Grade points |
|---|---|---|---|
| A+ | 4.0 | C | 2.0 |
| A | 4.0 | C- | 1.7 |
| A- | 3.7 | D+ | 1.3 |
| B+ | 3.3 | D | 1.0 |
| B | 3.0 | D- | 0.7 |
| B- | 2.7 | F | 0.0 |
| C+ | 2.3 |
There is no single official GPA scale. Many schools give an A+ the same 4.0 as an A, some give it 4.3, and some do not use plus and minus grades at all. This calculator counts an A+ as 4.0 and a D- as 0.7. If your school gives an A+ 4.3, the semester GPA here will come out slightly low; check your registrar's grading policy.
Two more things change the answer. Schools decide which courses count: pass/fail, withdrawn and repeated courses are often excluded or replaced, so leave them out of the list unless your school gives them grade points. And a school that reports a weighted GPA adds a bonus for honors or AP work — use the High School GPA Calculator for that.

Frequently Asked Questions
- How do I calculate my GPA?
- Convert each letter grade to grade points, multiply by the course's credit hours, add those products, and divide by the total credit hours. A 3-credit A and a 3-credit B give (3 × 4.0 + 3 × 3.0) ÷ 6 = 3.5. The calculator does this as you fill in the rows.
- What is an A- worth on the 4.0 scale?
- 3.7 grade points on the scale this calculator uses. Plus and minus grades move the base value by 0.3 in either direction, so a B+ is 3.3 and a B- is 2.7. Some schools use slightly different values, so confirm against your own grading policy.
- How do I calculate GPA with different credit hours?
- Enter the credits for every course. A GPA is weighted by credit hours, so a 4-credit course counts a third more than a 3-credit one and four times as much as a 1-credit lab. Do not average the letter grades without weighting them.
- How do I calculate my cumulative GPA?
- Type your current GPA and the credits it covers into the Cumulative GPA box. The calculator multiplies them to recover your earlier grade points, adds this semester's grade points and credits, and divides. If you only have a GPA for each term, use the Cumulative GPA Calculator instead.
- Do pass/fail classes affect GPA?
- Usually not. Most schools leave pass/fail courses out of GPA but count the credits toward graduation, so leave them out of the list. A failing grade in a graded course does count: it adds credits with zero grade points.
- Is a 3.5 GPA good?
- On the 4.0 scale, 3.5 is roughly halfway between B+ and A- and is a strong result at most schools. Honors cutoffs such as the dean's list vary by school and college, so check the number your institution publishes.
