Why Weighted Grading Matters
Most school assessments are not a simple average — they are weighted to reflect the relative importance of each component. A final exam might count for 40% of the grade while weekly homework counts for 10%. Without a weighted calculation, raw averages misrepresent student achievement and can lead to inaccurate grade reporting.
The Free Assignment Grading Calculator handles weighted grading automatically. Enter each component — homework, midterm, project, final exam — with its score, maximum marks, and percentage weight. The tool instantly calculates the overall weighted percentage, converts it to a letter grade using your chosen scale, shows the GPA equivalent, and flags whether the student has passed.
Three grading scales included
- US A–F with +/− — the standard 13-tier scale from A+ (97–100) to F, with GPA equivalents from 0.0 to 4.0.
- UK Honours Degree — First Class, Upper Second (2:1), Lower Second (2:2), Third, and Fail, with standard percentage thresholds.
- Simple A–F / Pass–Fail — streamlined scales for schools that don't use +/− modifiers or only need a binary outcome.
UniCloud360 Grade Book calculates weighted grades for every student in your class simultaneously, applies your custom scale, generates individual grade reports, and pushes results to your student information system — no spreadsheets required.

What Educators Are Saying
Trusted by lecturers and students across Sri Lankan universities
"I used to manually calculate weighted grades in Excel every term. This tool does it instantly and gives me a PDF I can file straight away. The breakdown bars make it easy to explain to students why they got a particular grade."
"The UK Honours scale option is perfect for our A-Level equivalent courses. Finally a free tool that isn't locked to the US grading system. The GPA column is an added bonus for our international students."
"I use this to cross-check my grade book calculations before submitting. The visual breakdown helps me spot immediately if a student's poor exam performance is being masked by strong coursework — or vice versa."
"We shared this with all our teachers at the start of the semester as a quick reference tool. The pass/fail threshold indicator is particularly useful for our school's minimum grade policy."
