How the weighted average is calculated
Each mark is multiplied by its weighting, the results are added up, and the total is divided by the sum of the weightings. An assessment worth 40% counts for more than one worth 30%.
Your weightings don't have to add up to 100%. If you've only had some assessments back, enter those and the calculator shows your average so far, along with how much of the total weighting it covers.
The classification uses the usual UK boundaries: 70% or more is a First, 60% to 69% an Upper second (2:1), 50% to 59% a Lower second (2:2), 40% to 49% a Third, and under 40% is below a pass.
Worked examples
With marks of 65% (weighted 30%), 58% (weighted 30%) and 72% (weighted 40%): 65 × 30 + 58 × 30 + 72 × 40 = 6,570, and 6,570 ÷ 100 = a weighted average of 65.7%. That's equivalent to an Upper second (2:1).
If only the first two have been marked, choose 2 assessments: 65 × 30 + 58 × 30 = 3,690, and 3,690 ÷ 60 = 61.5% so far, with 60% of the total weighting entered.
Your final degree classification
The classification here is a guide to what an average mark is equivalent to. Universities work out final degrees in their own way: they often weight later years more heavily, may discount some modules and have rules for marks just below a boundary.
Check your university's or course handbook's regulations for how your degree is calculated.

How much the third assessment counts. Shown when you choose 3 or more assessments.
Assessment 4: mark
Your mark for the fourth assessment. Shown when you choose 4 or more assessments.
Assessment 4: weighting

CALCULATOR QUESTIONS
Grade calculator questions
How do I calculate a weighted average?
Multiply each mark by its weighting, add the results together and divide by the total of the weightings.
What if my weightings don't add up to 100%?
That's fine. The calculator divides by the total weighting you entered, so you get your average so far. At least one weighting must be above 0.
What mark do I need for a First?
An average of 70% or more is usually equivalent to a First, and 60% or more to a 2:1. Your university's own rules decide your final classification.
Can I use this for A levels or GCSEs?
You can use it to average any weighted percentage marks, but the degree classification only applies to undergraduate degrees.
