Final Grade Calculator

Calculate what grade you need on the final exam to get your desired course grade.

Formula
Required = (Target - Current x (1 - Weight)) / Weight
What is This Tool?

This calculator determines the minimum score you need on your final exam to achieve a target course grade. It accounts for your current grade in the course and the weight (percentage) that the final exam contributes to the overall grade.

Formula
Required Score = (Target Grade - Current Grade x (1 - Final Weight)) / Final Weight All values in percentages. Weight entered as % (e.g., 30 for 30%).
Worked Examples

1. Need an A in the course

Given: Current: 85%, Target: 90%, Final weight: 30%

Required = (90 - 85 x 0.70) / 0.30

Required = (90 - 59.5) / 0.30

Required = 30.5 / 0.30 = 101.7%

Result: 101.7% (nearly impossible without extra credit)

2. Maintaining a B

Given: Current: 82%, Target: 80%, Final weight: 25%

Required = (80 - 82 x 0.75) / 0.25

Required = (80 - 61.5) / 0.25 = 74%

Result: 74% needed on the final
