About Gradeculator
Gradeculator is a free collection of grade and GPA tools built for students at every level — high school, college, and graduate school. Every calculator runs entirely in your browser, so your data is never sent to a server and you get results instantly, without loading screens or sign-up walls.
Calculate Your GPA the Right Way
A GPA (Grade Point Average) is the most common way schools measure academic performance. Our GPA Calculator lets you enter each course, its credit hours, and the letter grade you earned. It multiplies grade points by credit hours, sums the result, and divides by total credit hours — the standard weighted-average formula used by virtually every institution in the United States. If your school uses honor or AP weighting, use the Weighted GPA Calculator instead.
Plan for Finals Before They Arrive
The Final Grade Calculator answers the question every student asks in the last week of term: "What do I need on my final to pass — or to keep my A?" Enter your current grade, the weight of the final exam, and your target grade. The calculator solves for the required exam score algebraically. Knowing this number early gives you a realistic study target instead of vague anxiety.
Score Any Test Instantly
Teachers and tutors can use the Test Grade Calculator to convert a raw score into a percentage and a letter grade in one step. Students can use it to check their score as soon as they get a paper back. Enter the number of correct answers and the total number of questions, and the tool handles the rest — including mapping the percentage to the conventional letter-grade scale.
Track Your GPA Across Semesters
Individual semester GPAs don't tell the whole story. Use the Cumulative GPA Calculator to combine results across all your semesters and see where you stand overall. If you're trying to recover from a rough semester, you can also work backwards: the What Grade Do I Need? tool shows you what GPA you'd need each semester to reach a cumulative target by the end of the year.
