Percentage to GPA Calculator
Type an overall percentage to see the equivalent US 4.0-scale GPA and letter grade.
Percentage to GPA, the US way
In the US, a percentage first becomes a letter grade, and the letter becomes grade points on the 4.0 scale. So 93–100% = A = 4.0, 90–92% = A- = 3.7, 87–89% = B+ = 3.3, and so on down to F = 0.0.
Because the mapping uses bands, two slightly different percentages can land on the same GPA. For a full transcript GPA across courses, use the GPA calculator.
There is no single official formula
Worth saying plainly: no universal rule converts a percentage to a 4.0 GPA. Every school and country draws its grade boundaries differently, so check the scale of the institution you're applying to. This tool uses the common US letter-grade bands, which is the right default for a US high school or college percentage.
If your percentage is from another country
The same number means different things in different systems. A 75% in the United States is a C, but in India a 75% is often excellent, closer to a 3.5 or 4.0 than to a C, and many Indian universities grade on a 10-point CGPA rather than a percentage at all. A raw percentage from outside the US can't be dropped into the US bands directly. For anything official, like a study-abroad or grad-school application, schools usually want a credential evaluation from a service such as WES rather than a self-calculated number.
Frequently asked questions
- How do you convert a percentage to GPA?
- We map the percentage to a US letter grade (90–92 = A-, 93+ = A, and so on), then to its 4.0-scale grade points. It's the most common US convention.
- Is there one official percentage-to-GPA formula?
- No — schools differ. Some use a flat linear formula, others use letter-grade bands like we do here. Check your school's scale for an official figure; this gives the standard US estimate.
- What about a 10-point CGPA?
- A common quick estimate is (CGPA ÷ 10) × 4. For exact conversion, use your university's published table.
- Can I use this for an international percentage?
- Treat it as a rough US-scale estimate only. Grade boundaries differ by country (a 75% in India is far stronger than a 75% in the US), so for official applications use a credential evaluator like WES instead.
