About the Imperial CGPA Calculator
Top STEM university in London using standard UK honours degree classification bands.
Imperial College London is a STEM-focused Russell Group university where undergraduate degrees are classified as First, 2:1, 2:2, or Third based on weighted percentage averages — not on a 4.0 CGPA scale. Engineering, medicine, and natural sciences programmes at Imperial use rigorous exam and coursework mixes. This calculator helps Imperial students see how module marks aggregate toward UK honours boundaries. Wrong scale? Tell us — or browse more United Kingdom calculators.
What Imperial students should know
Imperial year-by-year marks often feed into final class with increasing weight on later years — especially MEng programmes. Failed modules can trigger resits that cap marks at pass level, affecting averages differently than a simple F = 0.0 GPA rule. Students targeting finance or consulting graduate schemes should know many UK employers cite 2:1 minimum — track your weighted average, not a converted GPA.
How to use this calculator
- List each module with its credit value and percentage mark from Imperial's Student e-Service.
- Apply weightings from your programme handbook — later years may count double toward classification.
- Compare your cumulative weighted average to UK bands: First 70%+, 2:1 60–69%, 2:2 50–59%.
- For international applications, download official Imperial transcripts with degree classification.
Imperial grading system
Imperial follows UK honours standards: First Class (70%+), Upper Second (2:1, 60–69%), Lower Second (2:2, 50–59%), Third (40–49%), Fail (below 40%). STEM programmes may apply compensation rules across failed modules — check your department examination conventions.
The math behind semester GPA and cumulative CGPA is the same across most universities — see our CGPA formula guide for a worked example. For broader planning tips, read the complete CGPA guide on the homepage or browse student articles on the blog.
Percentage conversion
Imperial transcripts show module percentages and final degree class. There is no Imperial-certified "CGPA × 25" formula — UK classification replaces that concept entirely.
