GPA Calculator
Select a letter grade and enter credit hours for each course to calculate your GPA on the 4.0 scale. Works for a single semester or cumulative across all terms — just add all your courses. Each course is weighted by credit hours, so a 4-credit course affects your GPA four times as much as a 1-credit course. For converting a specific test score to a percentage and letter grade, use the grade calculator. For combining grades with different weights, the weighted average calculator handles custom weights.
When to use this calculator
Use this at the end of each semester to calculate your semester GPA, or enter all your completed courses to find your cumulative GPA. Also useful before a semester ends to project what GPA you'll need to reach a target.

How to Calculate
- Select the letter grade you received for each course from the dropdown.
- Enter the number of credit hours (units) for that course.
- Add more courses with the '+ Add course' button.
- Your GPA updates instantly as you enter grades.
Formula
Each letter grade has a point value (A = 4.0, B+ = 3.3, B = 3.0, etc.). Multiply each course's grade points by its credit hours, add all those up, then divide by the total credit hours. This is a weighted average — courses with more credits count proportionally more.
Examples
A (3cr), B+ (3cr), B (4cr), A- (3cr)
3.43 GPA
B (3cr), C+ (3cr), A (3cr)
3.10 GPA
A (4cr), A- (4cr), B+ (3cr)
3.71 GPA
Use Cases
- Checking your semester GPA as grades come in
- Calculating cumulative GPA across all completed courses
- Projecting the GPA needed this semester to hit a target
- Evaluating how a retaken course will affect your overall average
- Comparing GPA scenarios for graduate school applications
FAQ
What is a good GPA?
On the 4.0 scale: 3.7–4.0 is typically Dean's List range, 3.0–3.6 is good standing, 2.0–2.9 is satisfactory (meets most graduation requirements), and below 2.0 is academic probation at most universities. Graduate school applications generally expect 3.0+ for admission, and competitive programs want 3.5+.
How is GPA calculated?
Each letter grade maps to a grade point value (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0 — with +/− adjustments of 0.3). Multiply each course's grade points by its credit hours to get quality points. Sum all quality points, then divide by total credit hours. This is a weighted average where heavier courses (more credits) count more.
What is a 3.5 GPA as a letter grade?
A 3.5 GPA falls between a B+ (3.3) and an A- (3.7) — roughly equivalent to a high B+ average. It represents strong academic performance and qualifies for most Dean's List programs, which typically require 3.5 or higher.
Does a 3-credit course count more than a 1-credit course?
Yes — that's the point of the weighted average. A grade in a 3-credit course has three times the impact on your GPA as the same grade in a 1-credit course. This is why a low grade in a high-credit course like a major requirement hurts more than a low grade in a single-credit elective.
What GPA do I need to raise my average to 3.0?
It depends on how many credits you've already completed. The more prior credits you have, the harder it is to move the needle. If you have 60 credits at a 2.5 GPA and need a 3.0, you need to earn a 4.0 average in the next 60 credits — half your remaining degree — just to reach 3.0. Use this calculator to experiment with grade and credit combinations.
Is GPA calculated the same everywhere?
Most US universities use the 4.0 scale. However, some schools use a 4.3 scale where A+ = 4.3 rather than 4.0. UK universities use a different classification system entirely (First, 2:1, 2:2, Third) based on percentage marks rather than a GPA scale. If you need to convert a score to a percentage, the grade calculator handles that separately.
