Percentage to GPA Formula
The conversion is a simple proportion. Divide your percentage by 100, then multiply by the top of your GPA scale.
GPA = (Percentage ÷ 100) × GPA scale
For example, 87.5% on a 4.0 scale gives (87.5 ÷ 100) × 4.0 = 3.50. The same percentage on a 10.0 scale would give (87.5 ÷ 100) × 10.0 = 8.75, which shows why the scale matters so much. Never convert without knowing the scale, because the same percentage means a different GPA on each scale.
How to Use the Percentage to GPA Converter
Type your percentage into the first box. Then open the scale list and choose the scale your school uses: 4.0, 5.0, or 10.0. The tool will not convert until you choose a scale, so you cannot get a result from a guessed scale by mistake.
Tap Convert Percentage to GPA to see the result. The percentage must be between 0 and 100, and the GPA will never be above the top of the scale you chose.
Percentage to GPA Examples
Example 1 — 87.5% on a 4.0 scale gives (87.5 ÷ 100) × 4.0 = 3.50.
Example 2 — 100% on a 4.0 scale gives (100 ÷ 100) × 4.0 = 4.00. That is the top of the scale.
Example 3 — 85% on a 10.0 scale gives (85 ÷ 100) × 10.0 = 8.50. On a 10-point scale, each 10 percentage points are worth 1 GPA point.
Percentage to GPA Tips
Check your transcript or course guide for the scale. In the United States and Canada, a 4.0 scale is common, but some schools use a 5.0 scale for weighted courses, and a 10.0 scale is common in India and other countries.
Note that some boards use their own conversion. For example, one Indian board has used percentage ÷ 9.5 for its 10-point results. That is a board rule, not a general formula, so if your board gives you a factor, use that factor instead of this general converter, and ask your school if you are unsure.

Percentage to GPA FAQ
What does percentage to GPA mean? It means turning a percentage score, such as 87.5%, into a grade point average, such as 3.50 on a 4.0 scale, so it can be compared with GPA results.
Why must I choose a scale? Because the same percentage gives a different GPA on each scale. Choosing the scale stops a wrong guess from giving a wrong result.
What if my percentage is above 100? The tool asks you to check the number, because a percentage score cannot be above 100 in this converter.
Is the result official? No. It is a general conversion. Your school or board may use its own official conversion, and that one counts for applications.
Can I convert back from GPA to percentage? Yes. Use the GPA to Percentage converter on this site.
What if my school uses a weighted 5.0 scale? Choose the 5.0 scale in the list, not the 4.0 scale. The same percentage gives a higher GPA on a 5.0 scale, so converting on the wrong scale will understate a weighted result.
