Convert a Different Value
This page answers one conversion. For any other value, the interactive GPA scale converter takes a percentage, a GPA or a CGPA and returns the other two.
Converting a single number is not the same as calculating a GPA. If you want yours worked out from real courses and credit hours, use the GPA calculator.
How Percentage-to-GPA Conversion Actually Works
Percentage-to-GPA is a lookup, not an arithmetic formula. You find the letter-grade band your percentage falls in, and that band's grade point is your GPA contribution for that course. There is no division, no scaling, and no universal equation — anyone offering you one has picked a convention and not told you.
The bands below are the most common US convention: 93–100% is an A worth 4.00, 90–92% an A- worth 3.67, and so on down. A meaningful number of schools shift these by a point or two, and some use a plus/minus-free scale where every A is a flat 4.00 regardless of whether it was 93% or 99%.
Two things follow from the banding. First, precision is lost in one direction only: 93% and 100% both become 4.00, and no later calculation can tell them apart. Second, converting a whole transcript percentage-by-percentage and averaging the result is not the same as your official GPA, which weights each course by its credit hours. For that, use the GPA calculator.

Frequently Asked Questions
What is the formula to convert percentage to GPA?
There is not one. Percentages map to GPA through letter-grade bands rather than a formula: match the percentage to its band (93-100% is a 4.0, 90-92% is 3.67, and so on) and take that band's grade points. Any single-equation 'formula' you find is just one school's convention written out.
Is percentage divided by 25 a valid way to get GPA?
No, though it circulates widely. Dividing by 25 would make 75% a 3.0 and 50% a 2.0, when in reality 75% is a C (2.0) and 50% is a failing 0.0 on the standard US scale. The shortcut badly overstates grades in the lower and middle ranges.
Does my school use these exact bands?
Possibly not. The bands here are the most common US convention, but cutoffs vary by institution and sometimes by department. Your registrar publishes the official scale — for anything that matters, such as a scholarship threshold or a graduate application, use that one.
