Grade Calculator
Find out where you stand in a course and what you need on the work that is left. List each graded item with your score and its weight in the final grade; scores can be percentages or points such as 45/50. The calculator gives your current weighted grade, the points already earned towards the final grade and the average you need on the remaining weight to reach a target.

Example
Homework 92% (20%), midterm 78% (30%) and a quiz of 45/50 (10%) give a current grade of 5,080 ÷ 60 ≈ 84.67%. To finish with 85%, you need (8,500 − 5,080) ÷ 40 = 85.5% on the remaining 40%.
Frequently Asked Questions
How is a weighted grade calculated?
Multiply each score by its weight, add them up and divide by the total weight completed so far. That is your current grade on the work graded so far.
How do I work out what I need on the final?
Needed = (Target × 100 − Σ score × weight) ÷ remaining weight. If the final is worth 40%, the calculator uses that remaining 40%.
What if the weights add up to less than 100%?
The missing weight is treated as work still to come, which is what the “needed” figure is calculated for.
Can the answer be over 100%?
Yes, if the target cannot be reached with normal scores. The calculator says so plainly.
