Calculate your grade point average for high school or college — semester, cumulative, weighted, or unweighted. Free tools trusted by students worldwide.
Your GPA is one of the most important numbers in your academic life,affecting college admissions, scholarships, and honor society eligibility. Our GPA calculators make it easy to track exactly where you stand — and plan where you want to go. Free, instant, and private.
Calculating GPA by hand is error-prone because it's credit-weighted, not a simple average — a common mistake is averaging your grades directly, which gives the wrong answer when courses have different credit hours. A GPA calculator handles the math correctly and instantly, so you always know your real standing.
Beyond just computing a number, our calculator helps you plan: see how a target semester would change your cumulative GPA, understand the difference between weighted and unweighted scores, and know what academic honors your GPA qualifies for.
| Letter | 4.0 Scale | Percentage |
|---|---|---|
| A | 4.0 | 93-100% |
| A- | 3.7 | 90-92% |
| B+ | 3.3 | 87-89% |
| B | 3.0 | 83-86% |
| C | 2.0 | 73-76% |
| D | 1.0 | 63-66% |
| F | 0.0 | Below 60% |

Yes. The calculator works for both. High school students can use the weighted scale for AP/Honors courses, while college students can use credit hours and the cumulative mode to combine semesters.
The calculator uses the standard US 4.0 scale, which most schools follow. However, grading policies and weighting vary by institution. Always verify with your school's official scale for transcripts and applications.
Because a four-credit course moves your average twice as far as a two-credit course with the same grade. Averaging letter grades without weighting them by credit hours is the most common GPA miscalculation, and it can be off by several tenths of a point across a full semester.

Open GPA Calculator →A GPA converts letter grades into numbers, weights each by the credit value of the course, and averages the result. The weighting is the part students most often overlook: a four-credit course affects your average twice as much as a two-credit course with the same grade.
Scales vary between institutions and countries. The four-point scale is standard in the United States, but weighted scales that award additional points for advanced courses can exceed it, and many countries use entirely different systems. Always calculate against the scale your institution actually uses.
| Letter Grade | Typical Points (4.0 scale) | Common Percentage |
|---|---|---|
| A | 4.0 | 93 to 100 |
| A- | 3.7 | 90 to 92 |
| B+ | 3.3 | 87 to 89 |
| B | 3.0 | 83 to 86 |
| C+ | 2.3 | 77 to 79 |
| C | 2.0 | 73 to 76 |
| D | 1.0 | 63 to 66 |
| F | 0.0 | Below 60 |
An unweighted GPA caps at 4.0 regardless of course difficulty. A weighted GPA awards additional points for honours or advanced courses and can exceed 4.0. Institutions differ in which they use and how they recalculate transfer grades, so check before comparing figures.
