Use this free GCSE 9–1 grade calculator to combine your paper and component marks into an overall percentage and approximate grade from 9 to 1. You can also estimate what you need in your remaining exams to reach a target grade.
Approximate GCSE 9–1 bands. Real exam boundaries can vary by subject and year.
Add each assignment, quiz or exam with its percentage weight. Marks and weights are automatically clamped between 0 and 100.
| Assessment | Weight (%) | Score (%) | |
|---|---|---|---|
Choose a target overall percentage and the assessment you want to solve for. The calculator will estimate the minimum score needed on that assessment.
The GCSE grading system in England now mostly uses a numerical scale from 9 (highest) down to 1 (lowest), with U meaning ungraded. Grades roughly map onto the old A*–G system, but not exactly:
Exam boards like AQA, Edexcel and OCR set exact grade boundaries for each subject and each exam sitting, so the marks needed for a 7 or a 5 can vary slightly year to year. This calculator uses approximated percentage bands to give you a quick idea of where your overall mark sits on the 9–1 scale.
You can rename each row, add extra components or remove ones you don't need so that the calculator matches your exact subject structure.
If you've already taken some exams, you'll probably want to know:
"What do I need in Paper 2 to get at least a 5 (or a 7)?"
The "What do I need on the final?" panel is made for that. To use it:
This can help you decide how much to prioritise each paper when revising.
It's important to remember that real GCSE grade boundaries are set by exam boards after the exams have been marked. They can change slightly each year depending on how difficult the paper was and how students perform overall.
This calculator uses simple percentage bands to give an approximate idea of your grade. It's a great way to understand how your marks combine – but for final results, always check the official boundaries and your results from your school or exam board.
After GCSEs, you might go on to A-Levels, IB, or another route. These calculators can help at the next stage:
