US GPA Calculator 2026
US GPA Calculator — Convert International Grades to the Standard American 4.0 Scale
Use this free US GPA calculator by RevisionTown to calculate your high school or college GPA on the standard American 4.0 scale. Whether you are an international student converting foreign grades for US college admissions, or an American student computing your unweighted grade point average, this tool provides the exact formula and grade mappings used by US admissions offices.
The Gold Standard of US Admissions: Every high school and international curriculum uses different grading systems (100-point scale, A-E, 1-10, A-Level, IB, etc.). The unweighted 4.0 scale is the universal baseline used by US universities (Ivy League, state schools, private colleges) to compare all applicants fairly. This calculator strips away regional differences to show you exactly how US admissions officers view your academic record.

How to Use the US GPA Calculator
This US GPA calculator translates both domestic letter grades and international percentage systems into the universal American 4.0 grade point average. It accurately reflects how US college admissions officers and registrars calculate academic records.
- Select your input format — Choose whether you want to enter standard US letter grades (A, B, C) or percentages (e.g., 85%).
- Enter your courses — Click "+ Add Course" for each class on your transcript. Enter the subject name, the grade you received, the credit hours (1.0 for a standard year-long high school class, or 3.0/4.0 for a college course), and select the course type if applicable (AP, IB, Honors).
- Choose unweighted or weighted — We recommend "unweighted" as it is the universal standard used for comparison. Only select "weighted" if you want to see how US high schools calculate the 5.0 scale for advanced coursework.
- Review the conversion — Click "Calculate US 4.0 GPA" to see your exact American GPA, letter equivalent, and total quality points. The breakdown shows exactly how each course was mapped to the US scale.
The Standard American 4.0 GPA Formula
The United States uses a credit-weighted average system. Every grade is converted to a "grade point" value between 0.0 and 4.0. Those points are multiplied by the course's credit hours to generate "quality points."
Core GPA Formula
Quality Points Formula
Unweighted vs. Weighted GPA
The standard US GPA is unweighted, meaning the maximum possible score is a 4.0. An A in Physical Education and an A in Advanced Calculus both earn 4.0 grade points. This is the baseline number every US university uses to evaluate applicants from around the world.
A weighted GPA is specifically an American high school concept. Schools add "bonus points" to advanced classes to reward rigor:
On a weighted scale, an A in an AP class earns 5.0 points instead of 4.0. However, colleges strip these bonus points away during the admissions process to put every student (domestic and international) on a level playing field.
US Letter Grade to 4.0 Scale Conversion Chart
The standard American grading conversion maps percentage scores (out of 100) to letter grades and corresponding grade points on the 4.0 scale. This is the most common conversion scale used by the College Board and US institutions.
| Letter Grade | Percentage Range | Grade Points (4.0 Scale) | International Equivalent (General) |
|---|---|---|---|
| A+ / A | 93–100% | 4.00 | Excellent / First Class Honours (UK) / 10-9 (EU) |
| A- | 90–92% | 3.70 | Very Good |
| B+ | 87–89% | 3.30 | Good / Upper Second Class (UK) / 8 (EU) |
| B | 83–86% | 3.00 | Good |
| B- | 80–82% | 2.70 | Above Average |
| C+ | 77–79% | 2.30 | Average Plus / Lower Second Class (UK) / 7 (EU) |
| C | 73–76% | 2.00 | Average |
| C- | 70–72% | 1.70 | Below Average |
| D+ | 67–69% | 1.30 | Poor / Third Class (UK) / 6 (EU) |
| D | 63–66% | 1.00 | Barely Passing |
| F | Below 63% | 0.00 | Failing |
Note on Percentages: In the US system, anything below a 60% or 63% (depending on the specific school) is considered an F (0.0 points). In many international systems (like the UK), a 60% is a very strong score. International students must use an official credential evaluator to translate their specific curriculum grades to the US percentage equivalent before using the 4.0 conversion above.
Understanding the American Grading Context
How US Universities Review International Transcripts
If you are applying to a US university from another country, you do not actually convert your own GPA on your application. You report your grades exactly as they appear on your local transcript. The US admissions office then uses internal rubrics (or a third-party service like WES or ECE) to convert your grades to the US 4.0 scale so they can compare you to domestic applicants.
The "Course Rigor" Factor
Because the US system uses an unweighted 4.0 scale for baseline comparison, a student taking easy courses could have a higher GPA than a student taking difficult courses. US universities solve this by evaluating course rigor separately.
- Domestic rigor: Assessed by the number of AP, IB, Dual Enrollment, or Honors courses taken.
- International rigor: Assessed by the curriculum. Taking A-Levels, the full IB Diploma, or a rigorous national exam track (like the French Baccalaureate or Indian CBSE Class 12) demonstrates high rigor, making a 3.8 GPA in those systems highly competitive compared to a standard 4.0 elsewhere.
The A+ Discrepancy
Unlike some international systems where a 100% carries more weight than a 95%, the standard US 4.0 scale caps A+ and A both at exactly 4.00 points. Some institutions use a rarer "4.3 scale" where an A+ is worth 4.3, but for national standard comparison (like the Common App), the 4.0 cap applies.
Worked Example: Converting Percentages to the 4.0 Scale
Consider an international high school student whose transcript shows percentage grades, converted to the US 4.0 scale using the standard College Board mapping.
| Subject | Local Grade | US Credit Hours | US Grade Pts (from chart) | Quality Points |
|---|---|---|---|---|
| Mathematics | 88% (B+) | 1.0 | 3.30 | 3.30 |
| Physics | 94% (A) | 1.0 | 4.00 | 4.00 |
| History | 81% (B-) | 1.0 | 2.70 | 2.70 |
| Literature | 75% (C) | 1.0 | 2.00 | 2.00 |
| Art | 91% (A-) | 0.5 | 3.70 | 1.85 |
The student's converted US GPA is 3.07 on the 4.0 scale, roughly equivalent to a solid B average.
Frequently Asked Questions
What is a US GPA?
A US GPA (Grade Point Average) is an academic score used by American high schools and universities. It converts letter or percentage grades into a numerical scale, typically out of 4.0. An A is worth 4.0 points, a B is 3.0, a C is 2.0, a D is 1.0, and an F is 0.0.
Why do US colleges use a 4.0 scale?
The 4.0 scale provides a universal benchmark for college admissions officers to compare students from thousands of different high schools (both domestic and international) that use vastly different grading systems. It standardizes academic performance into one clean metric.
How do international students calculate their US GPA?
International students must first convert their local grades (A-Level, IB, national percentage exams, 1-10 scales, etc.) into the US equivalent percentage or letter grade using official conversion charts (like those from WES). Then, they use the standard 4.0 formula to find the average.
What is an unweighted vs. weighted US GPA?
An unweighted GPA maxes out at 4.0 and treats every class equally. A weighted GPA adds bonus points for advanced American classes (e.g., +1.0 for AP, producing GPAs up to 5.0). Colleges typically recalculate all applicants to the unweighted 4.0 scale for fairness.
Is a 3.5 US GPA good?
Yes, a 3.5 US GPA (roughly an A-/B+ average or 89-91%) is considered strong. It is competitive for most state universities and many private colleges. Highly selective institutions (like the Ivy League) typically look for unweighted GPAs of 3.8 to 4.0.
Does a 100% equal a 5.0 GPA?
No. On the standard US unweighted scale, the maximum grade points awarded is 4.0, regardless of whether you scored a 93% or a 100%.
How do credit hours work in the US formula?
Credit hours weight the GPA. An A (4.0) in a 4-credit course counts four times as much toward the GPA as an A in a 1-credit course. High school courses are typically 0.5 or 1.0 credits. College courses are typically 3.0 or 4.0 credits.
If I am applying from the UK, how do my A-Levels convert?
UK A-Levels are considered highly rigorous. Generally, an A or A* converts to a US A (4.0), a B to a US B (3.0), etc. Crucially, US admissions officers recognize that achieving an A in an A-Level is harder than a standard US high school class, so they factor that rigor into your evaluation alongside the 4.0 GPA.
What happens if my country considers 70% an 'A'?
You must use an official credential evaluation service (like WES or ECE). Because US grading considers 70% a C-, an unadjusted conversion would severely misrepresent your ability. Evaluating services understand your country's grading curve and will map a 70% 'A' to a US 93%+ 'A' (4.0).
Do US universities look at anything besides GPA?
Absolutely. US admissions are "holistic." They look at your 4.0 GPA, the rigorousness of your curriculum, standardized test scores (SAT/ACT if required), extracurricular activities, leadership, essays, and letters of recommendation.
