About this calculator
The Weighted Grade Calculator combines assessments that count for different proportions of the final grade. It is useful for coursework, exams, modules, essays, practicals, and portfolios where each item has a different weighting.
weighted grade calculator method
A weighted average multiplies each grade by its weight, adds the contributions, and divides by the total weight entered.
- weighted average = sum(grade x weight) / sum(weights)
- component contribution = grade percentage x weight
How to use the weighted grade calculator
- Enter each assessment name.
- Enter the grade or percentage for each assessment.
- Enter the weight for each assessment.
- Add more assessments if needed.
- Review each contribution.
- Check the final weighted average.
Worked examples
Coursework and exam
Input: Essay 65% at 40%, exam 72% at 60%
Calculation: 65 x 0.40 + 72 x 0.60
Result: 69.2%
Three assessments
Input: 65% at 20%, 72% at 30%, 58% at 50%
Calculation: 13 + 21.6 + 29
Result: 63.6%
Why weighted grades differ
A lower mark in a high-weight exam can pull the average down more than a low mark in a small coursework task.
Weight total
Weights often add to 100%, but the calculator can still normalise them if they add to another total.
UK grading disclaimer
This calculator is for general planning and education only. UK grades are not GPA. Actual GCSE, A-Level, degree, and UCAS outcomes depend on exam boards, universities, course rules, moderation, weighting, grade boundaries, and official published requirements.
- GCSE and A-Level boundaries are set after each exam series.
- Universities can use weighting, best-credit, compensation, or borderline rules.
- UCAS points do not guarantee entry; course requirements vary.
Frequently asked questions
Is this a UK calculator?
Yes. These calculators use UK-style GCSE, A-Level, degree classification, and UCAS concepts rather than US GPA.
Are the grade boundaries official?
No. They are approximate planning guides. Always check your exam board, school, university, or UCAS course page.
Can this predict my final official grade?
It can estimate from the data entered, but official results depend on marking, moderation, boundaries, and institutional rules.
Why do weights matter?
A high mark in a heavily weighted exam affects the overall grade more than the same mark in a lightly weighted assessment.
Does this use GPA?
No. GPA is not used for these UK-focused grade calculators.
