Grade Calculator
Combine your scores by weight to see your current overall grade.
How to use the Grade Calculator
- Enter each item’s score as a percentage.
- Enter how much each is worth (its weight).
- Read your weighted grade — blank rows are ignored.
Grade = Σ(score × weight) ÷ Σ(weight)
About the Grade Calculator
This calculator blends up to six scores into one overall grade by weighting each by how much it is worth. It multiplies every score by its weight, adds those up, and divides by the total weight — so a 90% on an exam worth half the grade counts for far more than a 90% on homework worth a tenth. Enter each item as a percentage with its weight, and leave the rows you don’t need blank.
Alongside the percentage it shows a letter using the usual cut-offs — A from 90, B from 80, C from 70, D from 60 and F below — though those thresholds themselves vary between schools and countries. The useful twist is that your weights don’t have to add up to 100%. If they don’t, the tool still divides by whatever weight you entered and tells you the total, so the number stays meaningful.
That makes it a real “where do I stand right now” tool rather than only an end-of-term one: enter just the items that have been graded and read the weighted average of those alone. When you want to know what the final exam still needs to score, switch to the final grade calculator; to turn a raw mark like 47/60 into a percentage first, the percentage calculator does it in one step.
Frequently asked questions
Do my weights have to add up to 100%?
No. If they don’t, the calculator still divides by the total weight you entered and shows you what that total is, so the grade is the weighted average of the items you actually gave it.
Can I use it before all my assignments are graded?
Yes — that is one of its main uses. Enter only the items you have marks for and it shows your standing on those so far. The letter and percentage reflect what has been graded, not the whole course.
How is the letter grade decided?
By fixed cut-offs: A from 90%, B from 80%, C from 70%, D from 60% and F below 60. These are common thresholds, but schools and countries set their own, so check yours.
What is the difference between this and a GPA?
This finds one class’s overall percentage from its weighted assignments. A GPA combines final letter grades across several courses on a 4.0 scale. Use this per class, then a GPA calculator across classes.
How many items can I enter?
Up to six scored components, each with its own weight. Leave any rows you don’t need blank and they are skipped.
