How is a weighted grade calculated?

A weighted grade multiplies each assignment score by its weight (importance), adds them all up, then divides by the total weight. For example: if a test worth 60% scores 80% and homework worth 40% scores 90%, the grade is (80×60 + 90×40) / 100 = 84%.

How to Calculate Your Grade

This calculator offers three ways to calculate your grade depending on what you need:

Weighted Grade — Each assignment or category has a different weight (importance). A final exam worth 40% matters more than homework worth 10%. This is the most common grading system at universities and colleges.
Final Exam Needed — Enter your current grade, the grade you want, and how much the final is worth. The calculator tells you exactly what score you need on your final exam.
Simple Average — All scores count equally. Enter any number of scores and get the average instantly.

How Weighted Grades Work

A weighted grade system assigns different levels of importance to different types of work. For example, a typical university course might be graded as: Homework 20%, Midterm Exam 30%, Final Exam 40%, Participation 10%.

To calculate the weighted grade: multiply each score by its weight percentage, add all the results together, then divide by the total weight (which should equal 100%).

Frequently Asked Questions

What if my weights don't add up to 100%? +

The calculator will warn you if your weights don't total 100%. It will still calculate based on the weights you entered but the result may not reflect your actual grade. Always make sure your weights total exactly 100% for an accurate result.

What score do I need to get an A? +

In the standard US grading scale, an A requires a score of 90% or above. Use the "Final Exam Needed" tab — enter your current grade, set desired grade to 90, enter your final exam weight, and the calculator will tell you exactly what you need to score.

Can I use this for university courses? +
