How it works
For each course you enter a letter grade and the number of credit hours. Each grade maps to a grade-point value on the standard 4.0 scale (A = 4.0, A- = 3.7, B+ = 3.3, and so on down to F = 0.0), with an optional 4.3 scale that gives A+ extra weight. Your GPA is the sum of grade points times credits for every course, divided by the total credits — a credit-weighted average. Heavier courses count more. All math runs locally in your browser.
GPA = Σ(gradePoint × credits) / Σ(credits)
Common use cases
- Computing your semester GPA before grades are officially posted.
- Projecting how an expected grade in one course shifts your average.
- Checking whether you will clear a GPA threshold for a scholarship.
Frequently asked questions
Does it use weighted or unweighted GPA?
It computes a credit-weighted GPA: each course contributes in proportion to its credit hours, which is how most colleges calculate it. A 4-credit course affects your GPA twice as much as a 2-credit one.
Can I use a 4.3 scale with A+?
Yes. Toggle the 4.3 scale to give A+ a 4.3 grade point; the default 4.0 scale caps A and A+ at 4.0, which many schools use.
Are my grades saved anywhere?
No. Everything is calculated in your browser and nothing is sent or stored. Refreshing the page clears your entries.
