How the Grade Calculator works
This weighted grade calculator multiplies each assessment score by its percentage weight, then adds the contributions. For example, an 80% exam worth 40% contributes 32 percentage points to the course grade.
Formula
Weighted course grade = Σ(score × weight) ÷ Σ(weights). If you enter points, the score is first calculated as points earned ÷ points possible × 100.
Example
A student earns 85% on homework worth 30%, 78% on a midterm worth 25%, and 92% on a project worth 45%: (85×0.30) + (78×0.25) + (92×0.45) = 86.4%.
Letter grade reference
| Letter | Typical percentage | GPA reference |
|---|---|---|
| A | 90–100% | 4.0 |
| B | 80–89% | 3.0 |
| C | 70–79% | 2.0 |
| D | 60–69% | 1.0 |
| F | Below 60% | 0.0 |
Schools use different cutoffs, plus/minus boundaries, and weighting policies. Treat the letter shown as a common reference and compare it with your syllabus.
Frequently asked questions
What if my weights do not add to 100%?
The calculator normalizes the entered weights so you can calculate a current grade while some course components are still missing. The result also shows the total weight entered.
Can I use points instead of percentages?
Yes. Enter points earned and points possible for each assessment; the calculator converts each row to a percentage before applying its weight.
Does this calculate the final exam score I need?
This tool calculates your current weighted grade. Use the Final Grade Calculator to find the score needed on a remaining exam for a target course grade.
