Grade Calculator — Final Grade Needed
Calculate the grade you need on your final exam to achieve your target course grade. Enter current grade, final weight, and desired grade to plan your studying.
About This Calculator
Wondering what score you need on the final exam to get an A in the class? Finals often count for 20-30% of your total grade, meaning a strong or weak performance can shift your letter grade by a full point. But figuring out the exact target score requires weighted average math that confuses most students — especially when different assignment categories carry different weights. Our grade calculator lets you enter your current scores, their weights, and your target final grade to compute the exact minimum score needed on remaining assignments or the final exam.
The Formula Behind This Calculator
Final = (Cat1 * W1) + (Cat2 * W2) + ... Weights must sum to 100% Needed score = (Target - Current) / Exam weight.
Understanding the math helps you verify results and make better decisions for your project.

FAQ
What if I need more than 100% on the final?
It means the target grade is mathematically impossible. Focus on studying to maximize your actual final grade instead.
How are weighted grades calculated?
Each category (homework, tests, final) contributes its weight percentage. Current grade × (1 - final weight) + final grade × final weight = overall grade.
Should I drop a class if I can't get my target grade?
Consider the impact on your GPA, financial aid, and graduation timeline. Sometimes a B is better than a W on your transcript.
