What the Grade Calculator does
Grade Calculator: calculates Grade % from Assessments: one per line: name, score%, weight%. Example: the sample loaded on the page gives grade % 82.7.
The Grade Calculator takes Assessments: one per line: name, score%, weight% and returns Grade %. Each change is reflected immediately, which suits quick what-if comparisons.
Institutions use different scales, and converting between them by hand invites mistakes. The Grade Calculator exists to take that particular chore off your hands.
No sign-up, no data collection, no processing queue, just code running locally.
Further down the page: what each field expects, how the result is derived, and one example worked from the defaults.
What do the Grade Calculator fields mean?
The Grade Calculator uses 1 input. Starting values are already in place, which saves the usual blank-form hesitation about what a field wants.
| Field | What to enter | Default |
|---|---|---|
| Assessments: one per line: name, score%, weight% | paste or type any amount of text | Homework, 88, 20 Midterm, 76, 30 Final, 82, 40 Participation, 95, 10 |
How does the Grade Calculator work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same calculation.
The guard clauses run before the formula does, which is why mistakes surface next to the field.
Worked example
These are the values the Grade Calculator loads by default, and the result it produces from them. The figures are the tool’s live defaults and its live output, so you can reproduce them exactly.
| Assessments: one per line: name, score%, weight% | Homework, 88, 20 Midterm, 76, 30 Final, 82, 40 Participat… |

| Grade % | 82.7 |

How to use it
- Paste your content into Assessments: one per line: name, score%, weight%.
- The output refreshes live, so you can stop as soon as the number looks right.
- The results panel then shows Grade %.
- The link encodes your inputs, so saving it is enough to reproduce the result later.
What this tool does not do
- Grading scales differ between institutions; check your own scale before relying on a converted figure.
- Weightings vary by course, so confirm the rules your school actually applies.
- The result reflects the moment you ran it; anything that changes over time is not tracked.
Frequently asked questions
Assessments: one per line: name, score%, weight%. That is the whole form. Defaults are loaded for all of them, which means a single edit is enough to get a meaningful answer.
With the values loaded when the page opens, grade % comes out as 82.7. That number tracks the inputs, so a small edit shows its sensitivity immediately.
No. There is no upload step, no database, and nothing to delete afterwards.
Free, and there is no upsell. The whole tool is the free version.
Reliable for the case described. Where more than one convention exists, the method section says which one is used.
