About this calculator
The Semester Grade Calculator estimates a semester or full-year average from module marks and credits. It is useful for university students tracking performance across modules during the year.
semester grade calculator method
A semester average is usually credit-weighted: each module mark is multiplied by credits, then divided by total credits.
- semester average = sum(module mark x credits) / sum(credits)
- credits completed = sum(module credits)
How to use the semester grade calculator

Worked examples
Equal-credit modules
Input: 64%, 71%, 58%, each 20 credits
Calculation: (64 x 20 + 71 x 20 + 58 x 20) / 60
Result: 64.33%
Mixed credits
Input: 70% at 40 credits, 60% at 20 credits
Calculation: (70 x 40 + 60 x 20) / 60
Result: 66.67%
Credits matter
A 40-credit module affects the average twice as much as a 20-credit module.
Classification guide
The classification shown is a simple guide. Final degree classification may use year weighting and university regulations.
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.
