Grade calculator for college students
Enter each category from your syllabus with its weight and the grade you earned. You get your current weighted grade, plus the exact score you need on everything left to finish at the grade you want. Free, no account, and the math runs in your browser.
Current grade
86.42%
Based on the 60% of your grade that has been graded so far.
95.38%
on the remaining 40% of your grade.
How weighted grades actually work
Your final grade is not the average of your assignment scores. It is the average of your category scores, weighted by how much each category counts. That is why a 95% on a 5% quiz barely moves anything and a 70% on a 30% midterm moves everything.
The math for one category is its grade times its weight. Score 92% on homework worth 20% and you have banked 18.4 of the 20 points available. Do that for every graded category, add the results, and divide by the total weight graded so far. That is your current grade — the number this calculator shows on the left.
The more useful number is on the right. To find what you need on the final, subtract the points you have already banked from your target, then divide by the weight still ungraded. The example loaded above has 51.85 points banked across 60% graded — an 86.42% — so finishing at 90 takes a 95.38% on the final, while finishing at 80 takes a 70.38%. Run your own numbers before you decide how hard to study. The answer is frequently the opposite of what you assumed: sometimes a target is already gone, and sometimes the exam you were panicking about only needs a 70.
Why this disagrees with Canvas
Canvas calculates from what your professor has entered, not from what your syllabus says. Ungraded work is usually skipped entirely, so a single graded quiz in week two can show you at 100% in a course you have barely started. Placeholder zeros cause the opposite panic. Neither number is your real standing.
The weights printed in your syllabus are the contract. That is what this calculator uses, and it is why the result here is worth more than the number on your dashboard. If you want the reasoning in full, read how Canvas calculates your grade.

How do you calculate a weighted college grade?
Multiply each category grade by its weight, add those results together, then divide by the total weight that has been graded so far. If you scored 92% on homework worth 20% of your grade, that category contributes 18.4 points. Adding every graded category and dividing by the weight completed gives your current grade.
What do I need on the final to get an A?
Subtract the points you have already earned from your target grade, then divide by the weight of the work still ungraded. This calculator does it automatically — enter your target in the "what do I need" box and leave the final exam grade blank.
Why is my current grade different from Canvas?
Canvas usually averages only the assignments your professor has entered, and many professors enter grades late or leave placeholder zeros in. This calculator uses the weights printed in your syllabus, which is what your final grade is actually based on.
What if my category weights do not add up to 100%?
The calculator flags it and keeps working, dividing by whatever weight you entered. Weights that miss 100% almost always mean a category from the syllabus is missing — participation and attendance are the two most commonly forgotten.
Does a higher grade on a small assignment matter?
Much less than students assume. A 2% discussion post moves your final grade by at most 0.02 points per percentage point earned, while a 30% midterm moves it 15 times as hard. Sorting your work by grade weight is the fastest way to decide what deserves your time.
Is this grade calculator free?
Yes, completely free with no account required. Nothing you type is sent anywhere — the math runs in your browser.
