A Level GPA Calculator

Start with your grades

Estimate your A-Level GPA

Start with one row for each subject. A subject name is optional, but adding one makes the breakdown, copied summary, and export easier to understand. Choose the qualification label and grade for every row. The AS Level or A Level label records context; it does not secretly halve or boost a course.

Equal weighting is the simplest choice when every subject should count the same. If your school or evaluator uses different course values, turn on credit weighting and enter the applicable number for each row. The calculator multiplies each point value by its credit value, adds those products, and divides by total credits.

Try the example to load Mathematics A*, Biology B, and Chemistry C. It produces a 3.00 estimate on the default 4.0 map. Reset returns to a clean starting state.

See the assumptions

Understand the 4.0 and 5.0 scenarios

The default assumption maps A* and A to 4 points, B to 3, C to 2, D to 1, and E or U to 0. With equal weighting, those points are added and divided by the number of valid subjects. Results are rounded to two decimal places only after the full calculation.

A* and A intentionally share the 4.0 ceiling in this starting map. That does not mean every university treats them identically. The separate 5.0 scenario uses A*=5, A=5, B=4, C=3, D=2, E=1, and U=0. It is an illustrative advanced-course comparison, not a claim that A-Levels automatically receive AP, honors, or weighted credit.

Avoid false precision

Compare mapping assumptions

There is no universal formula for converting A-Level grades to a US GPA. Universities, schools, admissions offices, and credential evaluators may use different mappings or may review the original grades without converting them.

The custom mapping sandbox lets you edit the points for each grade and reset them in one step. Compare the default, advanced-course, and custom scenarios without hiding their assumptions. The sensitivity range highlights the lowest and highest result and identifies which entered grades cause the difference.

This range is often more useful than a falsely precise single number. If changing A* from 4.0 to 4.33 shifts the result, the calculator shows both the size and source of that shift. Use only a mapping you can trace to the institution or process you are preparing for.

For a clear audit, keep the chosen policy beside the result.

What-if planning

Test a planned-grade scenario

Planning mode copies your current subjects into a separate what-if view. Move grades up or down and compare the planned estimate with the current estimate. Changing Chemistry from C to B in the sample raises the default estimate from 3.00 to 3.33, a difference of 0.33.

The planned result is not a forecast, guarantee, or admissions judgment. It answers one bounded question: how would this selected grade change affect the same formula? The current result remains the primary output while the planned value is clearly labeled as a scenario.

Portable and auditable

Save a transparent application summary

Copy summary creates text for your notes. Copy share link creates a bounded URL that restores valid subjects, settings, mappings, and the planned scenario. Invalid or oversized shared data is ignored safely.

Export CSV includes subjects, qualifications, grades, credits, every custom mapping value, the formula, rounded results, creation time, and an unofficial-estimate notice. Print result uses the same on-screen summary without unnecessary navigation or controls.

Each summary keeps the selected assumptions beside the result, making a later review easier to reproduce.

All arithmetic runs locally. GradeCal does not require a login and does not send entered subjects to a calculation server. A share link contains the state needed to restore your setup, so review it before sending it.

Use the right workflow

When this calculator is useful

Use the estimate to explore a high school, college, or university application that asks for a US-style GPA. Cambridge learners can also compare possible mappings with an adviser while keeping the arithmetic reproducible. Board-neutral labels are used because the receiving institution sets conversion policy.

Before submitting a GPA, check the application instructions. If a form says not to convert international results, enter the original grades instead. If it names an evaluator or publishes a table, reproduce that table in the custom mapping. For general US coursework, use the GPA calculator or high school GPA calculator. To combine terms, use the cumulative GPA calculator. You can also return to the GradeCal grade calculator.
