A weighted grade is a course grade in which each assignment counts for a set percentage of the total, rather than every assignment counting equally.
A syllabus that reads 20% homework, 30% midterm, and 50% final exam describes a weighted grade. The final exam moves your course grade 2.5 times more than homework, because it carries 2.5 times the weight.
Weights answer one question: how much of the course does this piece of work represent? A 100% score on a 5% quiz adds 5 points to your course grade. The same score on a 40% exam adds 40 points. Both are perfect scores; only one changes your grade meaningfully.
Three terms describe the same number: weighted grade, weighted course grade, and weighted average grade. Each equals the sum of every grade multiplied by its weight, divided by the total weight applied.
To calculate a weighted grade, multiply each grade by its weight, add the results, then divide by the total weight. Three steps produce the course grade.
When the weights of every graded item add up to 100, the denominator is 100 and the sum of weighted grade values alone gives the course grade.
A course splits the grade across 4 components: homework at 20%, quizzes at 15%, a midterm at 30%, and a final exam at 35%.
| Component | Grade | Weight | Grade × weight | Points earned |
|---|---|---|---|---|
| Homework | 92% | 20% | 1,840 | 18.40 |
| Quizzes | 88% | 15% | 1,320 | 13.20 |
| Midterm exam | 78% | 30% | 2,340 | 23.40 |
| Final exam | 85% | 35% | 2,975 | 29.75 |
| Course grade | — | 100% | 8,475 | 84.75 |
The weighted grade is 84.75%, a B. The plain average of 92, 88, 78, and 85 is 85.75%, a full point higher, because it ignores that the two weakest scores carry 65% of the course.
Enter one row per graded item, type the grade and its weight, and the weighted grade appears immediately with the letter grade beside it.
Type each score in the grade column. Two input modes cover both kinds of gradebook:
Type the weight from your syllabus in the weight column, as a percentage of the course. Weights of 20, 15, 30, and 35 describe a course where those four components make up the whole grade.
Enter only the work that has been graded. The calculator reports how much course weight you have covered and how much is still open, so a partial semester still produces an accurate current grade.
No button is needed — every keystroke recalculates. The result panel reports 5 figures:
Copy grade puts the percentage and letter on your clipboard. Copy step-by-step breakdown copies every multiplication and total as plain text for an email to your instructor.
A weighted grade counts each assignment by its share of the course; an unweighted grade counts every assignment equally. The two match only when all weights are the same.
| Method | How each score counts | Result on 92, 88, 78, 85 |
|---|---|---|
| Weighted grade | By syllabus weight: 20%, 15%, 30%, 35% | 84.75% |
| Unweighted grade | Every score counts once | 85.75% |
The 1-point gap comes from the midterm and final. Those two carry 65% of the course and hold the two lower scores, so weighting pulls the grade down. Reverse the scores and weighting would push it up instead.
One warning about vocabulary: weighted GPA means something different. There, weighting rewards course difficulty, adding points for AP, IB, and Honors classes. Inside a single course, weighting only reflects how much each assignment counts.
Weights below 100% still give a correct grade, because the calculator divides by the weight you actually entered. Weights above 100% mean an error in the syllabus reading.
Mid-semester, weights rarely total 100. Homework at 20% and a midterm at 30% cover half the course. Scores of 92 and 78 give (1,840 + 2,340) ÷ 50, a current grade of 83.60% across the 50% that has been graded.
Three situations need a second look:
Weights do not have to be percentages either. Points-based syllabi work the same way: enter 150 and 350 as weights for a 150-point project and a 350-point final, and the division by the total weight of 500 rescales everything.
Your current grade covers only the work already graded. Your final grade covers the whole course, so it moves as the remaining weight is scored.
Enter only the graded items and divide by the weight those items carry. With homework at 20% scoring 92 and a midterm at 30% scoring 78, the current grade is 83.60% over the 50% graded so far.
Read the two figures together. A current grade of 83.60% at 50% graded is provisional; the same grade at 95% graded is nearly settled.
Enter your target course grade in the panel below the rows. The calculator subtracts the points already banked and divides by the weight still open.
Holding 83.60% across 50% of the course, with 50% still open, an 88% target needs 92.40% on everything remaining. A 90% target needs 96.40%. A 95% target needs 106.40%, which is above 100% and therefore out of reach — the calculator says so rather than printing an impossible number.
| Target course grade | Needed on remaining work | Reachable |
|---|---|---|
| 85% | 86.40% | Yes |
| 88% | 92.40% | Yes |
| 90% | 96.40% | Yes, with a near-perfect finish |
| 95% | 106.40% | No |
A weighted grade produces one course grade. GPA takes that grade, converts it to grade points, and weights it by credits across every course.
The two calculations run in sequence. Weighting inside a course turns assignments into a course percentage. Weighting across courses turns those percentages into a grade point average, using credits as the weights.
| Step | Weights used | Output |
|---|---|---|
| Weighted grade | Assignment weights from the syllabus | 84.75% in one course |
| Letter grade | The school's grading scale | B |
| Grade points | The 4.0 scale | 3.0 |
| GPA | Credit hours per course | Average across all courses |
A course grade of 84.75% converts to a B on most scales, worth 3.0 grade points. Four courses worth 4, 3, 5, and 2 credits then produce the GPA through the same weighted method, with credits in place of assignment weights. Use the weighted GPA calculator to combine every course into one semester GPA.
Weighted GPA is a separate idea again: it adds 1.0 for AP and IB courses and 0.5 for Honors courses before averaging, which is why a high school weighted GPA can exceed 4.0. Use the weighted average calculator with credits as weights for that step.
Six mistakes account for nearly every mismatch between a hand calculation and the grade your instructor records.
The calculator surfaces the first four automatically. It flags weights that total more than 100%, refuses to invent a grade when the weight is zero, marks entries that are not numbers, and reports the weight graded so a missing category is visible.

A weighted grade is a course grade in which each assignment counts for a set share of the total. A syllabus of 20% homework, 30% midterm, and 50% final exam produces a weighted grade, where the final exam moves the result 2.5 times more than homework.
Multiply each grade by its weight, add those weighted values, then divide by the total weight. Scores of 92, 88, 78, and 85 at weights of 20%, 15%, 30%, and 35% give 8,475 ÷ 100, a weighted grade of 84.75%.
No, weights do not have to add up to 100%. The calculator divides by the weight actually entered, so a half-finished semester still returns a correct current grade. A total above 100% signals a double-counted component and is flagged.
No, enter numbers rather than letters. Convert each letter to the midpoint of its band first: A = 95, A− = 91, B+ = 88, B = 85, B− = 81, C = 75. The calculator returns the letter grade for you once the percentage is computed.
A weighted grade counts each assignment by its share of the course, while an unweighted grade counts every assignment equally. The same four scores of 92, 88, 78, and 85 give 84.75% weighted and 85.75% unweighted.
Yes, enter your target course grade in the panel under the rows. The calculator reports the score you need across the remaining weight, and states plainly when a target needs more than 100% and is out of reach.
Four causes explain nearly every gap: the LMS drops a lowest score, it excludes ungraded work while you entered zeros, it weights by points inside a category rather than by assignment, or extra credit sits outside the weighted total. Match those rules and the numbers agree.
Calculate Weighted Average Online
The weighted average calculator multiplies each value by its weight, adds the weighted sum, divides by the total of weights, and prints the weighted average beside the standard arithmetic mean. Course grades, GPA, portfolio returns, and probability distributions all run through the same 4 steps.
