A-Level Grade Calculator (A* to E)

Use this free A-Level grade calculator to combine your paper and component marks into one overall percentage and approximate A-Level grade from A* to E. You can also estimate what you need in your remaining exams to reach your target grade.

1. Select grading system

Approximate A-Level grade boundaries. Real exam boards may vary slightly.

Grade bands

How A-Level grades are usually set

Every exam board (AQA, Edexcel, OCR, etc.) sets its own detailed grade boundaries for each subject and each year. However, most students think of A-Level grades in broad bands:

  • A* – top performance, usually very high marks (often 90%+ in the A2 modules or combined score)
  • A – strong performance, around 80–89%
  • B – good performance, roughly 70–79%
  • C – solid pass, often 60–69%
  • D – pass, around 50–59%
  • E – minimum pass, around 40–49%

This calculator uses an approximate set of boundaries so you can quickly see what grade band your overall percentage falls into. Always check your exam board's official boundaries for exact results.

How to use this A-Level grade calculator

  1. Make sure the grading system is set to UK – A-Level (A*–E, U).
  2. Under "Assessments & weights", use each row for a:
    • Paper (e.g. Paper 1, Paper 2)
    • Component (e.g. coursework, practical)
    • Module or unit (if your course is modular)
  3. Set the Weight (%) for each paper or component based on how much it counts towards the final grade. For example:
    • Paper 1 – 40%
    • Paper 2 – 40%
    • Coursework – 20%
  4. After you get results, type your Score (%) for each paper or component into the table.
  5. The Grade summary card will show:
    • Your total weight
    • Your current average (based on completed components)
    • Your final percentage (when all marks are entered)
    • The approximate A-Level grade band (A*, A, B, C, D or E)

You can edit the names of each row, add more components or delete unused ones, so the calculator matches your exact exam structure.

Estimating what you need in your remaining papers

Closer to exam season, the big question becomes:

"What do I need on Paper 2 to get an A overall?"

The "What do I need on the final?" panel does this for you:

  1. Enter all the marks you already have (for completed papers or coursework).
  2. Choose a target overall percentage that matches the grade you are aiming for. For example:
    • 85% for a strong A
    • 90%+ if you're aiming for an A*
    • 70% for a B
  3. Pick the paper you want to solve for (e.g. Paper 2) in the dropdown.
  4. The calculator will display the minimum score you need on that paper to hit your target overall percentage.

This is a great way to plan your study time – you'll know which papers are most critical and what is realistically achievable.

Remember: real A-Level boundaries can change

Exam boards set official grade boundaries after each exam series, and they can change slightly each year and between subjects. This calculator is designed as a simple, percentage-based guide so you understand how your different papers and components combine.

For final, official grades, always refer to your exam board's published boundaries and your results statement.
