Whether you're tracking semester grades, cumulative performance, or planning ahead for admissions, this calculator handles the exact math your school uses. Enter your courses, credits, and grades — see your GPA in seconds.
How GPA Works in the United States
The US uses a 4.0 GPA scale. Letter grades convert to grade points like this: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, F = 0.0.
Some institutions extend the scale to 4.3 to recognize A+ grades, but 4.0 remains the standard. International applicants are almost always asked to provide a US-equivalent 4.0 GPA on their application forms.
High schools usually publish both a weighted and an unweighted GPA, but US colleges typically report only the unweighted version on the official transcript.
US GPA Formula
American schools use one consistent weighted-average expression. Many transcripts even print the numerator and denominator separately so students can audit the math:
Numerator: Σ (Letter Grade Value × Credit Hours)
Denominator: Σ (Credit Hours)
US GPA = Numerator ÷ Denominator
- Convert each letter grade to its 4.0-scale point value.
- Multiply by the credit hours for the course.
- Sum the quality points and divide by total credits.
How to Use the USA GPA Calculator
Three inputs per course is all it takes:
-
01
Add a row per course
Course name optional; credit hours and grade are required.
-
02
Enter US-style credit hours
1-credit labs and PE, 3-4 credit lectures, 4-5 credit science classes with labs.
-
03
Pick the letter grade
Plus and minus grades are supported.
-
04

The result is on the standard US 4.0 scale.
Worked Example: A US Sophomore Semester
Four classes, mixed grades:
| Course | Credits | Grade | Points |
|---|---|---|---|
| Biology 201 | 4 | A | 16.0 |
| US History | 3 | B+ | 9.9 |
| Statistics | 3 | B | 9.0 |
| Communication | 3 | A- | 11.1 |
Quality points: 46.0 ÷ 13 credits = 3.54 US GPA
Why US Schools Standardize on 4.0
The 4.0 scale is the common language of US academia. It makes it possible to compare students from very different schools, majors, and grading cultures. Almost every internal academic decision — admissions, dean's list, honors graduation — starts from a 4.0 GPA.
For international students applying to US programs, converting your home-country grades to a 4.0-scale GPA is usually mandatory. Most universities use services like WES or simply ask you to provide a 4.0 figure on the application.
Frequently Asked Questions
Quick answers about the USA GPA Calculator — how it works, what it counts, and how to read your result.
Each letter grade maps to a grade-point value: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, F = 0.0. Each grade is multiplied by the credit hours of that course, then the products are summed and divided by total credit hours. The result is your weighted-average GPA on the 4.0 scale.
Almost all undergraduate institutions cap at 4.0 on the unweighted scale, but some — Stanford, MIT, and a number of others — use a 4.3 scale that recognises A+ as 4.3. High schools also commonly use weighted 5.0 or 6.0 scales for AP and IB courses. Always check whether the GPA you are reporting is on the 4.0 or 4.3 scale and whether it is weighted.
It depends on the level of school and the program. For undergraduate admissions, 3.5+ is competitive at most public universities, 3.7+ at selective private colleges, and 3.9+ at the most selective. For graduate school, 3.5 is typically the minimum for serious applicants and 3.7+ for top programs. Below 3.0 you start to see scholarship eligibility and academic probation issues.
Most US universities accept evaluations from services like WES, ECE, or SpanTran. These evaluators apply standard conversion tables — for example, a UK 2:1 typically becomes a 3.3-3.7 US GPA, an Indian 8.0 CGPA on a 10-point scale becomes roughly 3.6 US GPA. The official conversion is whatever the evaluator returns; the US 4.0 figure you self-calculate is for reference only.
No — pass/fail grades are typically excluded from the GPA calculation. They count toward credit hours and graduation requirements but do not affect the grade-point average. The same usually applies to audit, withdraw (W), and incomplete (I) grades. Always confirm with your registrar — a handful of schools treat pass at a fixed point value, but exclusion is the norm.
