Calculate your final grade, GPA, and letter grade with our free weighted grade calculator. Add multiple assignments, tests, and weighted grades for accurate academic results.
Follow these three steps to calculate your weighted final grade and GPA in seconds.
List each assignment or exam name, score received, total points, and its weight percentage from your syllabus.
Select "Add More Grade" to include quizzes, labs, midterms, or final exams. There is no limit to how many you can add.
Click "Calculate Grade" to instantly view your overall percentage, letter grade, and GPA on the 4.0 scale.
Tip: Your weight percentages should add up to 100% for the most accurate result. If your syllabus uses point totals instead of percentages, divide each category's points by the total possible course points to find its weight. For example, if a midterm is worth 150 out of 500 total course points, its weight is 30%.
Here is what each number on your results card means and how to interpret your academic standing.
Your weighted average expressed as a percentage out of 100. This is the number most professors use on transcripts and progress reports. A percentage of 88.7%, for instance, tells you exactly where you stand before letter grades are applied.
The letter grade is assigned based on the standard U.S. grading scale, including plus and minus grades (A+, A, A-, B+, etc.). Each letter maps to a GPA point value. Your letter grade is what typically appears on your official transcript.
Your grade point average value for this course, expressed on the standard 4.0 scale. A 4.0 = A or A+, 3.7 = A-, 3.3 = B+, 3.0 = B, and so on. Multiply this by your credit hours to factor it into your cumulative GPA.
| Letter Grade | Percentage Range | GPA Value (4.0 Scale) |
|---|---|---|
| A+ | 97–100% | 4.0 |
| A | 93–96% | 4.0 |
| A− | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B− | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C− | 70–72% | 1.7 |
| D+ | 67–69% | 1.3 |
| D | 63–66% | 1.0 |
| D− | 60–62% | 0.7 |
| F | Below 60% | 0.0 |
Note: Some schools do not award A+ or use slightly different cutoffs. Always check your institution's official academic policy.
Learn how to calculate your weighted grade manually—useful for verifying results or doing a quick estimate during class.
An unweighted grade is a simple average: add all your scores and divide by the number of assignments. Every quiz, exam, and project counts equally. A weighted grade gives more value to specific categories. For example, a final exam may count for 40% of your overall grade while homework is only 20%. Most college courses and many high school classes use weighted grading, so understanding the formula is essential for tracking your academic performance.
Suppose your course syllabus breaks down like this:
Even though the midterm was a 78% (C+), strong performance on the heavily weighted final project pushed the overall grade to a B+. This is exactly why understanding assignment weights before test day gives you a strategic advantage.
Real scenarios where students use this calculator—and what to take away from each result.
Syllabus breakdown: Quizzes 15%, Lab Reports 20%, Midterm 25%, Final Exam 40%. A student scores 72% on quizzes, 88% on labs, 81% on the midterm, and 79% on the final.
Takeaway: The low quiz score (15% weight) had minimal impact. Improving lab performance would have the next-highest leverage before final grades close.
Participation 10%, Essays 35%, Vocabulary Tests 15%, Midterm 20%, Final Paper 20%. Student earns 95% participation, 89% on essays, 82% on vocab, 91% midterm, 87% final paper.
Takeaway: Essays carry the most weight (35%). Targeting a 93%+ on essays would likely push this student to an A− for the semester.
Homework 20%, Projects 30%, Midterm 20%, Final Exam 30%. Student scores 100% homework, 95% projects, 74% midterm, and needs to know what final exam score is required to earn a B (80%).
Takeaway: Strong earlier work means this student needs only 53% on the final to secure a B—relieving significant pressure heading into exam week.
Clinical Skills 25%, NCLEX Practice Tests 25%, Theory Exams 50%. Many nursing programs require a minimum 75% (C) in every category to pass. A student scores 80% clinical, 71% practice tests, and 78% theory.
Takeaway: The 71% practice test score is below the 75% pass threshold in many nursing programs. Always check your program's minimum category requirements, not just the overall weighted average.
One of the most common questions before finals week—here is how to calculate it yourself.
Your current grade is 83% based on work that counts for 65% of your final grade. Your final exam is worth the remaining 35%. You want to finish the course with at least a 90% (A−).
In this case, a 90% overall is mathematically out of reach—even a perfect score on the final would only bring you to about 88.55%. Knowing this early lets you adjust your target grade or discuss extra credit with your professor before it is too late.
Grading scales vary slightly by state and institution. A few things to keep in mind:
If your high school uses a weighted GPA system for honors or AP courses, your grade point value is bumped up—typically by 0.5 for honors and 1.0 for AP:
| Letter | Standard | Honors | AP / IB |
|---|---|---|---|
| A | 4.0 | 4.5 | 5.0 |
| B | 3.0 | 3.5 | 4.0 |
| C | 2.0 | 2.5 | 3.0 |
| D | 1.0 | 1.5 | 2.0 |

Common questions about grade calculations and how our calculator works
The calculator multiplies each assignment's percentage score by its weight, sums those products, then divides by the total weight. The result is your weighted final grade percentage, which is then converted to a letter grade and a GPA value on the 4.0 scale automatically.
Convert each score to a percentage (score ÷ total × 100), multiply each percentage by its weight, add all those values together, then divide by the sum of all weights. For example: (85% × 30) + (92% × 40) + (88% × 30) = 8,820 ÷ 100 = 88.2%.
Use this formula: Required Final Score = (Target Grade% − Current Grade% × Current Weight%) ÷ Final Exam Weight%. If your current average is 85% (worth 70% of your grade) and you need a 93% overall, you need: (93 − 85 × 0.70) ÷ 0.30 = (93 − 59.5) ÷ 0.30 = 111.7%—which is not achievable, so targeting a 90% (A−) may be more realistic.
An unweighted GPA uses a standard 4.0 scale regardless of course difficulty—an A in gym class equals an A in AP Calculus. A weighted GPA adds bonus points (typically up to 5.0) for honors, AP, or IB courses, rewarding students who take more rigorous classes. Most college admissions offices review both.
Yes. The calculator works for any academic level—middle school, high school, community college, and university. Simply enter your scores, total points, and the weight each assignment carries in your syllabus. There is no limit to the number of grade components you can add.
The calculator uses the standard U.S. grading scale: A+ = 97–100%, A = 93–96%, A− = 90–92%, B+ = 87–89%, B = 83–86%, B− = 80–82%, C+ = 77–79%, C = 73–76%, C− = 70–72%, D+ = 67–69%, D = 63–66%, D− = 60–62%, F = below 60%. Some schools use a simpler scale without +/− grades—check your institution's policy.
In most U.S. high schools and colleges, a D (60–69%) is technically a passing grade, but many colleges require a C or higher for a course to count toward your major, satisfy general education requirements, or maintain good academic standing. Graduate programs often require a B or better. Always verify your school's minimum passing requirements.
Yes. The calculator outputs full plus/minus letter grades (A+, A, A−, B+, B, B−, C+, C, C−, D+, D, D−, F) and maps each to the correct GPA value on a 4.0 scale—for example, A− = 3.7, B+ = 3.3, and B− = 2.7.
