Calculate your final grade and GPA from assignments, exams and coursework.
Enter your scores and weights. Weight can be percentage (they should total 100%).
A grade calculator helps students calculate their current course grade, final exam grade needed, and weighted average of all assignments. Our free online grade calculator is used by students from school to university to track academic performance and plan for their desired final grade.
This includes calculating a class exam grade as a percentage directly from points earned out of points possible, which is the most common single calculation students look for.For a weighted grade system: multiply each component's score by its weight percentage, add them all together, and divide by 100. Example: Assignments (30%) = 85%, Midterm (30%) = 78%, Final Exam (40%) = 92%. Weighted Grade = (85×30 + 78×30 + 92×40)/100 = (2550 + 2340 + 3680)/100 = 85.7%
Use our final grade calculator: Required Final Exam Score = (Target Grade − Current Grade × Current Weight%) / Final Exam Weight%. If you need a B (80%) overall, have 75% with 60% of grades in, and the final is worth 40%: Required Final = (80 − 75×0.6)/0.40 = (80 − 45)/0.40 = 87.5%.
A+ = 4.0, A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, F = 0.0. Different institutions may use slightly different scales, but this is the most common 4.0 GPA scale used internationally.
Many universities around the world, particularly in South Asia, use CGPA (Cumulative Grade Point Average) on a 10-point scale rather than the 4.0 scale common in the US. A commonly used conversion formula is Percentage = CGPA × 9.5, following widely used regional guidelines, though the exact multiplier can vary. For example, a CGPA of 8.5 converts to roughly 80.75% under this formula. Every university and grading board can have its own specific conversion formula, so always verify the exact method with your own institution before relying on a converted percentage for official purposes.
Many courses weight different assignment categories differently — exams might count for 50% of a final grade, homework for 20%, and participation for 30% — rather than simply averaging every individual grade equally. This means a single low quiz score has a very different impact on a final grade depending on how heavily quizzes are weighted relative to other categories, which is a common point of confusion for students trying to estimate their grade based on individual scores without accounting for the weighting scheme.
Calculating a weighted grade correctly requires multiplying each category's average by its weight percentage and summing the results, rather than simply averaging all individual assignment scores together regardless of category — a manual calculation error that's surprisingly easy to make and that can meaningfully misrepresent an actual current grade.
A common and genuinely useful grade calculation works backward: given a current grade, remaining assignment weight, and a target final grade, calculate exactly what score is needed on remaining assignments (often a final exam) to reach that target. This reverse calculation turns an abstract goal ("I want a B in this class") into a concrete, actionable number ("I need at least an 82% on the final exam"), which is far more useful for planning study time and effort appropriately.
Some courses allow a certain number of lowest scores within a category to be automatically dropped before calculating the category average, which meaningfully changes the impact of a single poor performance on the overall grade. Understanding whether a course uses this kind of policy, and how many scores it drops, is important context before assuming every single assignment score carries equal, permanent weight in the final calculation.
Each letter grade has a point value (A=4, B=3, C=2, D=1, F=0). Multiply each by credit hours, sum them up, then divide by total credit hours.
Typically, a grade of D (50-59%) is the minimum passing grade at most institutions, but many programs require a C or better for core courses.
Add up weighted scores for each assignment, quiz, and exam based on their percentage contribution to the final grade.
A weighted grade assigns different importance to different assessments. For example, exams might count 40%, assignments 40%, and quizzes 20% of the final grade.
