University Grade Calculator

This university grade calculator works out your current weighted average from the marks you've already got. It works whether your course grades are by simple percentage weighting or by credits and whether you're tracking one module or your whole degree.

If you already know your current average and want to know what you need on something you haven't sat for yet, that's a different calculation; head to our final and overall grade calculator instead, which works backwards from a target.

Add your marks above and the weighted average updates as you go. If you'd rather work it out by hand first, the explanation below walks through exactly how the math works, with a real example.

How a university grade calculator works

A university grade calculator doesn't just average your marks; it weights them. Every module, assignment, or year of your degree usually counts for a different share of your final result, so a straight average would be misleading. The formula behind every calculation on this page is:

That's it — multiply each mark by its weighting (or credits), add the results together, then divide by the total weighting. The calculator above does this for you automatically, but it helps to understand it, because no two UK universities weight a degree in quite the same way.

Worked example: calculating your current weighted average

Say you've completed four modules so far this year:

• Module A: 72%, worth 20 credits
• Module B: 65%, worth 20 credits
• Module C: 58%, worth 10 credits
• Module D: 80%, worth 10 credits

Multiply each mark by its credits, add them up, then divide by the total credits:

That 68.67% is your current weighted average across everything completed so far — not a prediction or a target, just where you actually stand right now based on real marks. As soon as a new module mark comes in, add it as a fifth row and the average recalculates automatically.

Calculating by credits instead of percentage weighting

Most UK degrees aren't weighted by a simple percentage split, they're built from credit-bearing modules, typically 120 credits per year and 360 across a standard three-year degree. If your university works this way, you don't need to convert anything by hand: enter the credit value next to each module instead of a percentage weighting, exactly as in the worked example above.

A module worth 20 credits counts for twice as much in your overall average as one worth 10 credits, regardless of how many modules you're taking that year. If you want a deeper breakdown of how 120, 180, or 360-credit structures affect your final number, the credit-weighted grade calculator is built specifically for that.

Got a mark as a raw score rather than a percentage?

You don't need to convert anything before entering it. If a piece of work was marked out of 80 and you got 46, enter "46 out of 80" directly, and the calculator handles the conversion for you as part of the weighted average.

This matters because percentages alone can be easy to misread when assignments are actually graded on all sorts of different totals — better to enter exactly what you were given.

Calculating a single module, unit, or assignment grade

Everything above works at the level of whole modules or whole years, but the same calculator handles a single module's internal breakdown just as well, if that's what you're working out first. A module is rarely just one mark: it's usually built from a mix of coursework, a final exam, a presentation, or a lab report, each carrying its own weight.

Add a row for each component the same way you'd add a row for each module, and the result is that module's own final mark, which you can then enter as a single row elsewhere if you're combining it into a year or course average.

One thing worth knowing before you do this: many UK universities cap a resit or deferred component at the bare pass mark, commonly 40%, regardless of how well you actually did on the resit. If a coursework component was originally failed and resat, entering your real resit score instead of the capped mark can overstate that module's result by several percentage points.

A resit (after an outright fail) is the case most likely to be capped; a deferral — sitting something late for the first time, usually due to illness or another accepted reason — is often treated as a genuine first attempt and may not be capped at all.

Some components are pass/fail only and don't belong in the percentage calculation at all, such as a lab safety sign-off or a placement attendance requirement, for example. Those work the same way as the hurdle warning described above: tracked separately, not folded into the weighted average.

From percentage to classification: First, 2:1, 2:2, or Third

Once you know your overall percentage, UK degrees convert it into a classification band: roughly 70%+ for a First, 60–69% for an Upper Second (2:1), 50–59% for a Lower Second (2:2), and 40–49% for a Third.

These bands are widely used but not perfectly standardised — exact boundaries, and how borderline cases are rounded, vary by university. For the full breakdown, including why a 70% in the UK system is treated very differently to a 70% elsewhere, see the degree classification calculator and our guide to how UK universities calculate your final grade.

If you already know your current average and want to know exactly what you'd need across the rest of your final year to reach a particular classification, that's a target calculation rather than a current-average one — the final and overall grade calculator is built for that, including a full worked example using real second-year and third-year weightings.

Studying at a specific university, or through the Open University?

The weighted average formula above is universal, but the fine print — which years count, how compensation works, what the classification boundaries actually are — differs from institution to institution. If you're at a university we've built a dedicated page for, such as the University of Portsmouth grade calculator, it's worth using that version instead, since it reflects your specific institution's rules rather than the general UK formula.

Open University students follow a noticeably different structure — modules are organised by level and credit rather than by academic year in the conventional sense — so if that's you, the Open University grade calculator is built around that structure specifically, rather than asking you to force it into a standard three-year model.

Applying abroad? Converting your UK grade to a US GPA

If you're using your UK degree for a US graduate school application, a percentage or classification on its own won't mean much to an admissions committee used to a 4.0 scale. Our UK grade to GPA conversion calculator handles that translation, and explains why a straight conversion isn't always the right move — some application portals specifically ask you not to self-convert your grade at all.

Built for how students actually use a calculator

This tool is deliberately built around a few things students kept asking for when we looked at how people actually talk about grade calculators online: nothing requires an account, your entries are saved automatically in your own browser so you can come back to them as new marks come in across the semester rather than starting over each time.

There's also a simple hurdle warning built in: if a module on your course has a minimum pass-mark requirement independent of the weighted average — common across UK universities — we'll flag it as something to double-check, rather than pretending every course works on weighted averages alone. We can't model every institution's specific compensation rules, so always confirm the exact policy in your course handbook; this calculator is a planning tool, not an official result.
