What is the Current Grade Calculator?
This tool tells you the grade you have earned so far in a course, based only on the assignments, quizzes, and tests that have already been graded. Instead of assuming missing categories are zero, it renormalizes your score over the weight that has actually been completed — giving you a fair snapshot of where you stand right now.
How to use it
For each grading category you have completed (for example, Homework, Quizzes, Midterm), enter the percentage score you earned and the weight that category carries in the syllabus. Leave a row blank if that work has not been graded yet. The calculator divides the total of your weighted points by the total weight you entered, so the result is your average across graded work only.
The formula explained
The current grade is computed as (Σ score × weight) ÷ (Σ weight completed). Multiplying each score by its weight gives the "points" that category contributes; dividing by the sum of the weights you actually entered scales the result back to a 0–100% grade. Because the denominator only counts completed weight, you do not get penalized for work that has not happened yet.
$$\text{Grade} = \frac{\sum (s_i \cdot w_i)}{\sum w_i}\\[1.5em]\text{where}\quad \left\{ \begin{aligned} \sum (s_i \cdot w_i) &= \text{S}_1\,\text{W}_1 + \text{S}_2\,\text{W}_2 + \cdots + \text{S}_5\,\text{W}_5 \\ \sum w_i &= \text{W}_1 + \text{W}_2 + \cdots + \text{W}_5 \end{aligned} \right.$$
Worked example
Suppose you have three graded categories: Homework 92% (weight 20), Quizzes 85% (weight 15), and a Midterm 78% (weight 25). The weighted sum is \(92\times20 + 85\times15 + 78\times25 = 1840 + 1275 + 1950 = 5065\). The total weight completed is \(20 + 15 + 25 = 60\). Your current grade is
$$5065 \div 60 \approx \textbf{84.42\%}$$
FAQ
Why doesn't this use the full 100% of weights? Because not all work is graded yet. It averages only what counts so far, which is your true standing today.
Do the weights need to add up to 100? No. They can be any positive numbers — the calculator normalizes by whatever total you enter.
Can I use point values instead of percentages? Yes, as long as you are consistent: use points earned vs. points possible as the score, and the category's point total as the weight.
