Assignment Grade Impact Calculator

Find out how a specific assignment score will affect your overall course grade.

Current Overall Grade (%)

Weight of Grades So Far (% of total course)

Assignment Score (%)

Assignment Weight (% of total course)

Calculate Impact Enter your grades and weights above to see the impact.

function assCalc() { var resultDiv = document.getElementById('ass-result');

var currentGrade = parseFloat(document.getElementById('ass-current-grade').value); var currentWeight = parseFloat(document.getElementById('ass-current-weight').value); var assignmentGrade = parseFloat(document.getElementById('ass-assignment-grade').value); var assignmentWeight = parseFloat(document.getElementById('ass-assignment-weight').value);

// --- Validation --- if (isNaN(currentGrade) || isNaN(currentWeight) || isNaN(assignmentGrade) || isNaN(assignmentWeight)) { resultDiv.innerHTML = 'Please fill in all four fields.'; return; } if (currentGrade 100) { resultDiv.innerHTML = 'Current overall grade must be between 0 and 100.'; return; } if (assignmentGrade 100) { resultDiv.innerHTML = 'Assignment score must be between 0 and 100.'; return; } if (currentWeight 100) { resultDiv.innerHTML = 'Current weight must be between 0 and 100.'; return; } if (assignmentWeight 100) { resultDiv.innerHTML = 'Assignment weight must be between 0 and 100.'; return; } if (currentWeight + assignmentWeight > 100) { resultDiv.innerHTML = 'The sum of current weight and assignment weight cannot exceed 100%.'; return; }

// --- Core Formula --- // New weighted grade after adding the assignment: // newGrade = (currentGrade * currentWeight/100 + assignmentGrade * assignmentWeight/100) // / ((currentWeight + assignmentWeight) / 100) var totalWeightDecimal = (currentWeight + assignmentWeight) / 100; var weightedPointsEarned = (currentGrade * (currentWeight / 100)) + (assignmentGrade * (assignmentWeight / 100)); var newGrade = weightedPointsEarned / totalWeightDecimal;

// Grade change var gradeChange = newGrade - currentGrade;

// Remaining weight var remainingWeight = 100 - currentWeight - assignmentWeight;

// Letter grade helper function letterGrade(g) { if (g >= 90) return 'A'; if (g >= 80) return 'B'; if (g >= 70) return 'C'; if (g >= 60) return 'D'; return 'F'; }

var changeSign = gradeChange >= 0 ? '+' : ''; var changeColor = gradeChange >= 0 ? '#27ae60' : '#c0392b'; var oldLetter = letterGrade(currentGrade); var newLetter = letterGrade(newGrade);

resultDiv.innerHTML = 'New Overall Grade: ' + newGrade.toFixed(2) + '% (' + newLetter + ')' + 'Previous Grade: ' + currentGrade.toFixed(2) + '% (' + oldLetter + ')' + 'Grade Change: ' + changeSign + gradeChange.toFixed(2) + '%' + 'Total Weight Counted So Far: ' + (currentWeight + assignmentWeight).toFixed(2) + '%' + 'Remaining Course Weight: ' + remainingWeight.toFixed(2) + '%'; }

#### Formula

New Overall Grade = (Current Grade × Current Weight + Assignment Score × Assignment Weight) ÷ (Current Weight + Assignment Weight)

Where all weights are expressed as percentages of the total course grade (must sum ≤ 100%).

Example: Current grade = 85%, current weight = 70%, assignment score = 92%, assignment weight = 15%: New Grade = (85 × 0.70 + 92 × 0.15) / (0.70 + 0.15) = (59.5 + 13.8) / 0.85 = 73.3 / 0.85 ≈ 86.24%
