1. Weighted Course Grade Formula
Weighted Grade (%)=
∑ (Assignment Grade × Assignment Weight)∑ Total Category Weights
2. Required Final Exam Score Formula
Needed Final Score=
Target Grade − [ Current Grade × (1 − Final Weight) ]Final Exam Weight
Step-by-Step Calculation Breakdown
Example 1: Weighted Term Grade (Homework 20% @ 95%, Midterm 30% @ 82%, Final 50% @ 88%)
Class Grade=
(95 × 20) + (82 × 30) + (88 × 50)20 + 30 + 50
=
1,900 + 2,460 + 4,400100
=87.60% (B+)
Example 2: Target Final Score (Current Grade 85%, Target Grade 90%, Final Exam Weight 30%)
Required Score=
90 − [ 85 × (1 − 0.30) ]0.30
=
90 − 59.500.30
=101.67%

Frequently Asked Questions

How do weighted grades work?
Each assignment or category is assigned a weight (percentage of total grade). Your grade in each category is multiplied by its weight, then all weighted scores are summed. For example, if homework is worth 20% and you score 95%, that contributes 19 points toward your total.
What if my weights don't add up to 100%?
The calculator handles this correctly. If your entered weights sum to less than 100%, your grade is calculated proportionally over the completed weights. If they exceed 100%, the weights are normalized proportionally.
How accurate is the 'What do I need on my final?' calculation?
It is mathematically exact for the formula Final = [Target - Current × (1 - Weight)] / Weight. It assumes the final is the sole remaining graded item.
How does this translate to my cumulative GPA?
Your final course percentage corresponds to a standard 4.0 GPA scale (e.g. 93%+ = 4.0, 90–92% = 3.7). You can use our College GPA Calculator to combine this course grade with your remaining credit hours.
