When different pieces of work count for different amounts, working out your overall mark gets tricky. Our Grade Calculator handles the weighting for you.
How to use the calculator (Grade Calculator)
Choose what to work out:
- My weighted average: list each piece of work as its name, mark and weight, like Essay 72 30.
- What I need in the final exam: enter your current grade, the final's weight and the grade you want.
How it works
Weighted average = Σ (mark × weight) ÷ Σ weights
Mark needed in the final = (target − current × (1 − final weight)) ÷ final weight
Worked examples
- With the calculator's default settings, coursework of 72% (30%), a mid-term of 65% (20%) and a project of 80% (10%) give a weighted average of 71%, with 40% of the course still to go.
- If you're on 68% and the final is worth 40%, you need 73% in the final to finish on 70%.
UK degree classifications

Frequently asked questions
What if my weights don't add up to 100%?
The calculator works out your average for the work you've done so far.
What if I need more than 100%?
Your target isn't reachable with the final alone. Ask your tutor about other options.
