Calculate a credit-weighted UK module average, an indicative honours classification and an illustrative 4.0 GPA estimate.
Enter module marks and credits
Add at least one module with a valid mark and credit value.
What is the United Kingdom GPA Calculator?
The United Kingdom GPA Calculator combines module marks according to their credit values. A 40-credit module therefore contributes twice as much to the weighted average as a 20-credit module. It then shows a broad UK honours band and an illustrative GPA on a 4.0 scale.
Most UK universities primarily report percentages, module grades and degree classifications rather than one national GPA. There is no single official UK-to-4.0 conversion used by every university, employer or international credential evaluator. The GPA result on this page is therefore a planning estimate, not an official transcript conversion.
How to use the calculator
- Enter an optional module name.
- Enter the percentage mark from 0 to 100.
- Enter the module’s credit value.
- Add more module rows where needed.
- Select Calculate GPA.
Only completed rows are counted. If a row contains a mark without credits, or credits without a mark, the calculator asks you to complete it.
Credit-weighted average formula
For example, a 70% mark in a 20-credit module and a 60% mark in a 40-credit module produce a weighted average of 63.33%, not 65%. The 40-credit module has twice the influence.
Indicative UK degree classifications
| Weighted average | Indicative band |
|---|---|
| 70% and above | First-class honours |
| 60% to 69.99% | Upper second-class honours (2:1) |
| 50% to 59.99% | Lower second-class honours (2:2) |
| 40% to 49.99% | Third-class honours |
| Below 40% | Below the typical honours pass threshold |
These are broad planning bands. Universities may use borderline rules, compensation, resits, capped marks, excluded modules, year weightings, dissertation requirements and programme-specific regulations. Your examination board determines the official result.
How the illustrative 4.0 GPA is estimated
Each module percentage is assigned an indicative grade point and then weighted by credits. The mapping used is: 70%+ = 4.0; 65–69.99% = 3.7; 60–64.99% = 3.3; 55–59.99% = 3.0; 50–54.99% = 2.7; 45–49.99% = 2.3; 40–44.99% = 2.0; 35–39.99% = 1.0; below 35% = 0.
This mapping is an explanatory convention created for this calculator. Do not submit it as an official conversion unless the receiving institution explicitly accepts that method.
University rules can be more detailed
UCL’s published 2026/27 academic manual, for example, says final weighted marks are calculated from credit-weighted counting marks and explains separate year weightings and borderline classification rules. Other universities may use different algorithms. Always check the regulations and handbook for your exact programme and year of entry.
What the result does not prove
- Your final official degree classification
- An institution-approved US GPA equivalence
- Whether failed or reassessed modules are capped or excluded
- How different years of study are weighted
- Eligibility for progression, graduation or admission

Frequently asked questions
Do UK universities use GPA?
Some programmes report or request GPA, but UK undergraduate results are commonly expressed as percentages and degree classifications. There is no single universal UK GPA scale.
Why are module credits needed?
Credits determine how much each module contributes to the weighted average.
Is the 4.0 GPA result official?
No. It is an illustrative estimate based on the mapping published on this page.
Does the calculator apply year weightings?
No. Entered modules are weighted only by credits. Apply your university’s year rules separately.
Can this predict my final degree classification?
It provides a broad indicative band, but official classifications depend on your university and programme regulations.
Important: Use your official transcript, programme handbook and university regulations for formal decisions.
