GPA Calculator Formula
The GPA Calculator formula calculates calculate grade point average from course grades and credit hours on the US 4.0, UK honours, or Australian 7-point scale.
This formula is used because it connects the main inputs directly to the result people need.
It keeps the work clear, so you can change one value and see how the answer moves.
GPA calculators weight each course by its credit hours, so a high grade in a four-credit module moves the average further than the same grade in a one-credit module. This tool supports the US 4.0 scale, UK honours classification bands, and the Australian 7-point scale, because the same transcript produces very different numbers depending on which system is applied.
