What Is GPA?
Grade point average (GPA) is a single number that summarizes your academic performance. It is the average of your course grades, with each grade converted to points and weighted by the course's credit hours, so a 4-credit class counts more than a 2-credit one. Schools, scholarship committees and employers use GPA to compare students, and graduate programs and honors societies often set minimum cut-offs. Enter your courses, credits and grades into this GPA calculator to see your term or cumulative GPA.
How GPA Is Calculated
GPA = Σ(grade points × credits) ÷ Σ(credits). Each letter grade has a point value, you multiply it by the credits for that course, add up the results, and divide by the total credits attempted. For example, a B (3.0) in a 2-credit physics course and an A (4.0) in a 3-credit English course give 6 + 12 = 18 quality points over 5 credits, for a GPA of 3.6.
Worked Example
Four courses — an A (3 credits), a B+ (3 credits), an A- (4 credits), and a B (3 credits) — average out to a 3.52 GPA across 13 total credit hours.
The Common US Grade 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, D− = 0.7
- F = 0.0
Some schools award an A+ worth 4.3, others cap at 4.0, and some use E instead of F. Pass/fail, incomplete and withdrawn courses normally do not count toward GPA at all. Always check your school's own rules, because the scale is not universal.
Weighted vs. Unweighted GPA
An unweighted GPA treats every class equally on a 4.0 scale. A weighted GPA gives extra points to harder courses — often +1.0 for AP or IB and +0.5 for honors — so it can go above 4.0. Colleges generally recalculate GPA on their own terms, so it is worth knowing both numbers.
Ways to Raise Your GPA
- Focus your effort on high-credit courses, where each grade moves the average the most.
- Retake a course if your school replaces the old grade, and ask how repeats are counted.
- Use the early weeks of a term to ask for help; recovering late is much harder.
- Remember that the more credits you already have, the slower your cumulative GPA moves — so every term matters early on.

Worked example
Four courses — A (3 credits), B+ (3 credits), A- (4 credits), and B (3 credits) — earn 12.0 + 9.9 + 14.8 + 9.0 = 45.7 grade points across 13 credit hours, for a weighted GPA of 45.7 ÷ 13 ≈ 3.52.
Frequently asked questions
How is weighted GPA calculated?
Each course's letter grade converts to grade points (A = 4.0, B+ = 3.3, etc.), multiplied by its credit hours. Sum all the grade points, divide by total credit hours.
Does this use a plus/minus grading scale?
Yes — grades like A-, B+, and C- use the standard 4.0-scale point values (A- = 3.7, B+ = 3.3, C- = 1.7) rather than rounding to the nearest whole letter.
What if my school uses a different scale?
This calculator uses the most common US 4.0 scale. If your institution weighs grades differently (e.g., a 4.3 for A+), the totals will differ slightly from your official transcript.
Does this account for honors or AP course weighting?
No — it uses standard, unweighted grade points for every course. Schools that add extra points for honors/AP classes calculate weighted GPA differently.
