A-Level GPA Calculator
Enter your A-Level subjects, grades, and optional weights/credits to calculate a weighted GPA on a 4.0 scale. This tool also shows estimated UCAS tariff points.
How this GPA calculator for A Levels works
A Levels are usually reported as letter grades, but many universities, scholarship systems, and international applications ask for a GPA-like number. This page uses a practical conversion model so you can estimate your GPA quickly and consistently.
The calculator supports weighted entries, which is useful if one subject carries more value in your reporting system. If your subjects should count equally, simply leave every weight as 1.
A-Level to GPA conversion scale used
This tool converts grades using a common 4.0 approximation:
- A* = 4.0
- A = 3.7
- B = 3.0
- C = 2.0
- D = 1.0
- E = 0.7
- U = 0.0
It also estimates UCAS tariff points for full A Levels: A* = 56, A = 48, B = 40, C = 32, D = 24, E = 16, U = 0.
Step-by-step manual GPA formula
1) Convert each grade to grade points
Example: A* (4.0), B (3.0), A (3.7).
2) Multiply by each subject weight
If all weights are 1, this is the same as a simple average.
3) Add all weighted points
Sum all subject results together.
4) Divide by total weights
GPA = Total Weighted Grade Points / Total Weight
Example calculation
Suppose your grades are:
- Mathematics: A* (weight 1)
- Physics: A (weight 1)
- Chemistry: B (weight 1)
GPA = (4.0 + 3.7 + 3.0) / 3 = 3.57
Estimated UCAS points = 56 + 48 + 40 = 144
Tips for using A-Level GPA in applications
- Always check if the university has its own official conversion method.
- If required, provide both your original A-Level grades and converted GPA.
- Keep your conversion scale transparent in your personal statement or additional notes.
- For competitive programs, include predicted grades and achieved grades clearly.
Frequently asked questions
Is this an official GPA conversion?
No. It is an estimate based on a common 4.0 mapping. Institutions can use different policies.
Should I use weighted or unweighted GPA?
Use unweighted when every subject is treated equally. Use weighted only if your school or target institution applies subject weighting.
Can this calculator handle AS and A2 separately?
Yes, by entering each as separate lines and assigning appropriate weights if needed. If unsure, keep weights equal and report your grading structure in notes.
