Calculate your weighted grade and exactly what you need on what's left — saved per course, so you can keep several subjects going at once. Saves in your browser. Free.

Key takeaways:
This calculates your weighted subject grade from individual assessment components, the same maths behind our standalone Grade Calculator — but built to keep a separate, saved gradebook for every course you're taking, rather than one working session you re-enter each visit.
Add a course, list its assessments with weight and mark, and switch to another course whenever you need to — each one keeps its own saved list, so mid-semester you can check where every subject actually stands.
Multiply each mark by its weight, add every component, and you have your subject total out of 100 — provided the weights themselves add to 100%. What's left ("what do I need on the rest") reverses that: subtract what's already earned from your target, divide by the weight still available, and that's the average required on everything remaining. If that number is above 100%, the target isn't reachable with what's left, and the calculator says so rather than showing an impossible figure.
For due dates and status alongside the same weight and mark data, use the Assignment Grade Weight Planner. Once results are finalised for the semester, the Semester Grade Calculator tracks your GPA history across terms.
How is this different from the site's Grade Calculator?
Our Grade Calculator is a single-subject, single-session what-if tool. This version saves a separate gradebook per course in your browser, so you can switch between several subjects and come back to each later without re-entering everything.
How do you calculate a weighted grade?
Multiply each assessment's mark by its weight, add the results, then divide by 100. An 80% mark on a 30%-weighted assignment contributes 24 marks toward your subject total.
What does the target grade calculation show?
The average you need across everything not yet marked to reach your chosen target — and whether that's still mathematically possible with the weight remaining.
Where is my course data stored?
Entirely in this browser's local storage, on this device, organised by course name. Nothing is uploaded. Export a CSV or PDF backup per course if you want a copy.
What if my weights don't add up to 100%?
The calculator warns you rather than silently rescaling. Check your subject outline — assessments are sometimes split across sections, and participation or attendance components are easy to miss.
Can I track multiple subjects?
Yes — add a course, build its assessment list, then add another course and switch between them with the dropdown. Each course's assessments and results are kept separate and saved.
