How to Calculate Your UK Degree Classification
A UK degree classification is usually based on a weighted average rather than a simple average of all your marks. Each module contributes according to its credit value, and many universities also apply a year weighting so that later study counts more heavily. A typical calculation starts by multiplying each module mark by its credits, adding those totals together, and dividing by the total number of credits included in the calculation.
For example, a 40-credit dissertation marked at 68% contributes more to your average than a 20-credit taught module marked at 68%. This is why high-credit modules can change your predicted classification quickly. The calculator on this page lets you enter each module separately so you can see how credits and year weighting affect your estimate.
UK Degree Classification Boundaries
The most common UK undergraduate honours boundaries are 70% and above for a First, 60-69% for a 2:1, 50-59% for a 2:2 and 40-49% for a Third. These boundaries are a useful guide, but they are not the whole story. Some universities use borderline rules, compensation rules, best-credit methods or programme-specific algorithms.
The rough US GPA guide on this page is included only as a broad orientation tool. There is no single official conversion between UK percentages and US GPA. If you are applying for postgraduate study, employment or immigration purposes, use the conversion method requested by the receiving university, employer or evaluation service.
How Year Weighting Works
Many UK universities place more weight on the final year than on Year 2 because final-year work is usually more advanced. Common examples include Year 2 at 40% and final year at 60%, Year 2 at 30% and final year at 70%, or an even 50:50 split. Some courses use final-year-only classification, and some four-year courses include additional rules for placement years, study abroad or integrated master’s years.
This calculator includes common presets because they are useful for planning, but they should not be treated as official rules. Always check your course handbook, assessment regulations or student records system before making decisions based on an estimate.
Example: Year 2 40% and Final Year 60%
Imagine your Year 2 credit-weighted average is 62% and your final-year average is 68%. With a 40:60 weighting, the calculation would be 62 x 0.4 plus 68 x 0.6. That gives 24.8 plus 40.8, which equals 65.6%. Under standard boundaries, that would usually sit in 2:1 territory.
If your final-year average increased to 72%, the same weighting would produce 62 x 0.4 plus 72 x 0.6, giving 68.0%. You would still be below the standard First boundary, but close enough that your university’s borderline policy might become relevant. This is exactly why it is useful to model different outcomes before your final assessments.
What Mark Do I Need for a First?
The mark you need for a First depends on your completed credits, your current average, the credits you have left and your university’s classification rules. If you have many credits remaining, your final classification can still move substantially. If only a small number of credits remain, the required mark may become very high or mathematically impossible.
Use the target simulator to estimate the average you need in your remaining modules. If the required mark is above 100%, the target is not mathematically reachable from the numbers entered. If the required mark is high but possible, focus first on high-credit modules, read marking criteria carefully and ask for feedback early.
