Weighted Course Grade Calculator

Formula

Weighted grade = (First grade × First weight+Second grade × Second weight) ÷ (First weight+Second weight)

Worked example

With First grade: 80 %, First weight: 40 %, Second grade: 90 %, Second weight: 60 %, weighted grade is 86 %.

Calculation method

The rule is Weighted grade = (First grade × First weight+Second grade × Second weight) ÷ (First weight+Second weight).

For this weighted course grade example, changing first grade from 80 % to 81 % while keeping the other inputs fixed changes weighted grade from 86 % to 86.4 %.

Reading weighted grade

The answer shows the combined grade or the exam score needed for a selected target. In the worked values on this page, first grade 80 %, first weight 40 %, second grade 90 %, second weight 60 % produce weighted grade 86 %.

Practical use

Use it to test a final-grade scenario or understand the impact of an assessment. The specific task here is to find weighted grade from first grade, first weight, second grade, second weight.

Limits and common mistakes

Check that weights reflect the syllabus and that all scores use the same percentage scale. Extra credit and dropped assignments are not modeled. Verify first grade in % before interpreting weighted grade; a value measured on another basis would answer a different question.

Read the example and units

The worked values on this page use first grade 80 %, first weight 40 %, second grade 90 %, and second weight 60 %. With those exact entries, the calculator reports weighted grade 86 %. The output describes weighted grade under the displayed equation. It does not automatically include a separate cost, rate, or quantity absent from the listed fields. The score and weight fields describe one grading scheme. Check whether grades are percentages or grade points, and whether a weight is a share of the whole course or only one component. The calculator cannot infer an institution’s transcript or rounding policy from the numbers entered.

Compare one changed input

For a second scenario, change only first grade 80 % to first grade 88 % and leave the other example entries alone. The result for weighted grade changes from 86 % to 89.2 %. Comparing one changed input at a time shows exactly which assumption drove the difference in this calculation. A changed score or weight illustrates this grading equation only. Check whether the alternate score is achievable and whether the weights still match the course rules before treating it as a study target.

How to interpret this kind of result

A weighted course grade combines component scores according to their stated weights. The weights determine each component’s influence on the result; a higher-weight assessment changes the average more than a lower-weight one. The formula divides by the total entered weight, so the two weights act as relative shares even if they do not add to exactly 100. For this weighted course grade calculation, first grade in %, first weight in %, second grade in %, and second weight in % determine weighted grade; the displayed weighted grade 86 % belongs to that exact combination rather than to a different rate, term, or measurement basis.

Scope and practical checks

Partial credit, extra credit, dropped assessments, or a curve can make an official grade differ from the two-component model. Check the course policy before inferring a final mark. Retain enough decimal precision during intermediate steps, then apply the institution’s rounding rule at the end. Check the first grade in %, first weight in %, second grade in %, and second weight in % entries against the quantities in your own situation before using weighted grade; this page cannot infer a field or condition that you did not enter.

Common questions

What does this weighted course grade result include?

The weighted grade comes from first grade in %, first weight in %, second grade in %, and second weight in % using the displayed rule Weighted grade = (First grade × First weight+Second grade × Second weight) ÷ (First weight+Second weight). It does not automatically include a condition absent from the listed inputs. Compare the entered scores and weights with the actual course rules.
