A fast way to calculate your GPA (a credit-weighted grade average) from the grades and credits of your courses. Pick a grading scale — US 4.0 (A–F), US 4.0 with +/− (A− = 3.7, B+ = 3.3, and so on), a 4.3 scale where A+ = 4.3, Japan's common 4-point university scale (秀 = 4, 優 = 3, 良 = 2, 可 = 1, 不可 = 0), or a 5-point report-card scale — then enter a grade and the number of credits for each course. The GPA is computed on the spot as the sum of (grade points × credits) divided by total credits. Course names are optional and never affect the result; use them as labels if you like. Add as many rows as you need with "Add course" and remove any row with the × button. Alongside the GPA, the result panel shows your total credits, total quality points (grade points × credits) and the number of courses counted — handy when a scholarship, transfer, graduate or exchange application asks for those figures. Everything recalculates instantly as you change a grade or credit value, and switching scales keeps your existing grades wherever the same letter exists. Because grades can be personal data, this tool performs every calculation entirely inside your browser, with nothing uploaded, stored or sent to a server. Note that GPA methods vary by school and department — the cap on A+, how failing, repeated, transfer or pass/fail courses are treated, rounding, and which courses are excluded all differ — so this is a guideline; confirm your official GPA against your transcript or institution's rules.
How to use
- Choose a grading scale in the toolbar (US 4.0 / 4.3, +/− grades, Japan's 4-point, or a 5-point scale).
- For each course, pick a grade and enter the credits. The course name is optional. Use "Add course" for more rows.
- Your GPA, total credits and quality points appear instantly on the right. Grades are computed in your browser and never sent anywhere.
FAQ
Are the grades and credits I enter uploaded anywhere?
No. All calculation runs in your browser with JavaScript. Grades, credits and course names are never uploaded, stored, or sent to a server — so it's safe even though grades can be personal data.
How is the GPA calculated?
It's a credit-weighted average: GPA = sum of (each course's grade points × its credits) ÷ total credits. For example, an A (4.0) worth 4 credits and a B (3.0) worth 2 credits give (4×4 + 3×2) ÷ (4+2) = 22 ÷ 6 ≈ 3.67. Rows with no grade selected, or with zero or blank credits, are left out of the total automatically.
Which grading scales are supported?
US 4.0 (A–F), US 4.0 with plus/minus grades (A− = 3.7, B+ = 3.3, etc.), a 4.3 scale where A+ = 4.3, Japan's common 4-point university scale (秀 = 4, 優 = 3, 良 = 2, 可 = 1, 不可 = 0), and a 5-point report-card scale (5–1). Switching scales swaps the grade options and keeps your selection wherever the same grade exists.
Can I compute an unweighted average instead?
Yes. The calculator weights by credits, so to get a plain (unweighted) average where every course counts equally, just set every course's credits to the same value — for example 1. The result is then the simple mean of your grade points.
How should I handle failing, repeated or pass/fail courses?
The tool simply averages the rows you enter. Schools differ on whether an F counts in the denominator, whether a repeated course replaces the old grade, and whether transfer or pass/fail courses are excluded from the GPA. To exclude a course, leave it out (or leave its grade unselected). Check your institution's rules for the official treatment.
Can I use this result directly in an application?
Use it as a guideline. GPA methods vary by school and by the program you're applying to — including the A+ cap and rounding — so always confirm your official GPA against your transcript or your institution's stated method before submitting it.
