Grade and GPA Calculators
Free tools for students to plan final exam scores, calculate weighted grades, and estimate semester or cumulative GPA.
Which calculator should I use?
The right tool depends on what question you are trying to answer. If you want to know what score you need on your final exam to reach a target course grade, start with the Final Grade Calculator. If you already know all your scores and want to see where your class grade currently stands, use the Grade Calculator or the Weighted Grade Calculator when your syllabus assigns different percentage weights to homework, quizzes, and exams.
For GPA, use the GPA Calculator to estimate a single semester from letter grades and credits. If you want to see how one semester changes your overall record, the Cumulative GPA Calculator lets you enter your current GPA and credit total alongside your projected semester grades. High school students should use the High School GPA Calculator, which handles both weighted (5.0 scale) and unweighted (4.0 scale) GPA, and supports the honors and AP course point boosts that most high school grading systems apply.
Grade calculators vs. GPA calculators
Grade calculators work within a single course. They take your scores — on individual assignments, quizzes, or exams — and return a percentage or letter grade for that class. GPA calculators work across courses. They take the final grade from each class, convert it to a grade point value on the 4.0 scale, weight it by credit hours, and produce a single number that summarizes academic performance for a semester or an entire academic career.
Most students need both at some point during the semester. You might use a grade calculator mid-semester to check where you stand in each class, then use a GPA calculator at the end of term to estimate how your grades will affect your overall GPA before official results are posted.
How accurate are these calculators?
These tools use the standard formulas and grade scales used by most US colleges and high schools. Results are estimates. Your official grade or GPA is determined by your school's registrar and may differ if your school uses a non-standard grade scale, applies grade replacement policies, rounds differently, or excludes certain course types from GPA calculations. When in doubt, verify your grade scale in the course syllabus or your school's academic catalog. Read our guides for detailed explanations of how each calculation works.
