Grade Needed to Pass Calculator
Find out what grade you need on your remaining assessments or final exam to achieve your desired passing grade in a course.
Current Grade (%)
Weight of Completed Work (%)
Percentage of the total course grade already graded (e.g. 70 means 70% of the course is done).
Desired Final Grade (%)
Calculate ...
function graCalc() { var resultDiv = document.getElementById('gra-result');
var currentGrade = parseFloat(document.getElementById('gra-current-grade').value); var currentWeight = parseFloat(document.getElementById('gra-current-weight').value); var desiredGrade = parseFloat(document.getElementById('gra-desired-grade').value);
// --- Input validation --- if (isNaN(currentGrade) || isNaN(currentWeight) || isNaN(desiredGrade)) { resultDiv.innerHTML = 'Please fill in all three fields.'; return; } if (currentGrade 100) { resultDiv.innerHTML = 'Current Grade must be between 0 and 100.'; return; } if (currentWeight = 100) { resultDiv.innerHTML = 'Weight of Completed Work must be between 1 and 99 (exclusive). If 100% of the course is graded, no remaining work exists.'; return; } if (desiredGrade 100) { resultDiv.innerHTML = 'Desired Final Grade must be between 0 and 100.'; return; }
// --- Core formula --- // Let: // W1 = weight of completed work (as a decimal) // W2 = weight of remaining work = 1 - W1 // G1 = current grade (as a decimal) // D = desired final grade (as a decimal) // // Final Grade = W1 * G1 + W2 * G2 => solve for G2: // G2 = (D - W1 * G1) / W2
var W1 = currentWeight / 100; var W2 = 1 - W1; var G1 = currentGrade / 100; var D = desiredGrade / 100;
var G2 = (D - W1 * G1) / W2; var G2pct = G2 * 100;
var html = '### Result '; html += ''; html += 'Grade Needed on Remaining Work';
if (G2pct You have already passed! ✓'; html += 'Even scoring 0% on the remaining ' + W2.toFixed(4)*100 + '% of the course, your final grade would be ' + (W1 * currentGrade).toFixed(2) + '%, which exceeds your desired grade.'; } else if (G2pct > 100) { html += '' + G2pct.toFixed(2) + '% — Not achievable'; html += 'You would need more than 100% on the remaining work. Consider adjusting your desired grade.'; } else { var color = G2pct ' + G2pct.toFixed(2) + '%'; }
html += 'Remaining Course Weight' + (W2 * 100).toFixed(2) + '%'; html += 'Points Already Earned (weighted)' + (W1 * currentGrade).toFixed(2) + '%'; html += 'Points Still Needed (weighted)' + Math.max(0, desiredGrade - W1 * currentGrade).toFixed(2) + '%'; html += '';
resultDiv.innerHTML = html; }
#### Formula
The final course grade is a weighted average of completed and remaining work:
Final Grade = (W1 × G1) + (W2 × G2)
Solving for the required grade on remaining work (G2):
G2 = (Desired Grade − W1 × Current Grade) ÷ W2
- W1 = Weight of completed work (as a decimal, e.g. 0.70 for 70%)
- W2 = Weight of remaining work = 1 − W1
- G1 = Current grade on completed work (as a decimal)
- G2 = Required grade on remaining work (as a decimal)
