GPA
Calculator

Add each course you have taken or are currently taking. For every course, select the number of credit hours and the letter grade you earned. The calculator converts each letter grade to its numeric equivalent on the standard 4.0 scale used by most US colleges and universities.

For each course, the tool multiplies the credit hours by the grade points to produce quality points. For example, a 3-credit course with a B+ (3.3) generates 9.9 quality points. An A in a 4-credit course produces 16.0 quality points.

Your cumulative GPA is calculated by dividing the total quality points by the total number of credit hours. The formula is: GPA = Total Quality Points ÷ Total Credits. This weighted average ensures that courses with more credit hours have a greater impact on your GPA than lighter courses.

The calculator also displays your Latin honors classification based on common US university thresholds: Summa Cum Laude for 3.9 and above, Magna Cum Laude for 3.7 and above, and Cum Laude for 3.5 and above. You can use the percentage calculator to work out what percentage of a perfect 4.0 your GPA represents.

Understanding how GPA is calculated is easier with concrete examples. Here are three typical scenarios showing the step-by-step math behind the number.

Different academic and professional milestones require different GPA thresholds. Here is a quick reference for common targets that college students aim for.

The grade point average is the standard measure of academic achievement at US colleges and universities. Most institutions use an unweighted 4.0 scale where A = 4.0 and F = 0.0. Some high schools use a weighted scale that goes up to 5.0 for honors and AP courses, but this calculator focuses on the standard 4.0 scale used in higher education.

Your GPA matters for graduate school admissions, scholarships, Dean's List eligibility and Latin honors at graduation. Many scholarships require a minimum 3.0 GPA, while competitive graduate programs often look for 3.5 or higher. Employers in fields like finance, consulting and engineering also consider GPA during early-career hiring, though its importance diminishes with work experience.

Credit hours reflect the weight of each course in your schedule. A typical lecture course is 3 credits, while lab courses or intensive seminars may be 4 or 5 credits. One-credit courses exist for physical education, music ensembles or short workshops. Because GPA is credit-weighted, performing well in higher-credit courses has more impact on your overall average. Use our mean calculator if you want to find simple unweighted averages of your grades.

If you fail a course or earn a low grade, check whether your institution offers grade replacement. Many schools allow you to retake a course and replace the original grade in your GPA calculation, though the original attempt may still appear on your transcript. This is one of the most effective ways to recover from a poor semester.

Transfer students should note that most universities only count courses taken at their institution toward the cumulative GPA. Credits from your previous school transfer, but the grades typically do not factor into your new GPA. This can be an advantage if your earlier grades were lower.

Your semester GPA only includes courses from a single term. Your cumulative GPA includes every graded course across all semesters. Both are calculated the same way — total quality points divided by total credits — but the cumulative version spans your entire academic career.

A single bad semester does not ruin your cumulative GPA if you have enough strong semesters to balance it out. Conversely, a great semester will have less impact on your cumulative GPA as you accumulate more credits. After 60 credits, each individual course accounts for only a small fraction of the total.

To plan ahead, try entering your expected grades for next semester into the calculator alongside your current courses. This lets you see how your GPA will change before you commit to a course load — useful if you are trying to hit a specific threshold for a scholarship or honors eligibility.

GPA expectations vary significantly across disciplines. STEM fields like engineering, chemistry and physics tend to have lower average GPAs — typically between 2.8 and 3.2 — because grading curves are steeper and coursework is more demanding. Humanities and social science majors often average between 3.2 and 3.5, while education and communications programs frequently average 3.4 or higher.

This matters because graduate admissions committees and employers generally understand these differences. A 3.3 in mechanical engineering carries different weight than a 3.3 in English. Many medical schools and law schools publish the average GPA of admitted students by undergraduate major, which can be useful context when evaluating your own standing.

If you are choosing between majors and worried about GPA impact, focus on the subject you genuinely enjoy. Students tend to earn higher grades in courses that interest them. Use this GPA calculator to model different scenarios — enter your current grades alongside projected grades in courses from each major to see where you might land. You can also use our percentage calculator to convert your GPA to a percentage for scholarship applications that require it.

Graduate admissions offices look beyond the single cumulative GPA number. Most programs calculate a major GPA using only courses in your field of study, which may differ significantly from your overall GPA. If your major GPA is stronger than your cumulative GPA, highlight it in your application materials.

Many programs also pay attention to your trend over time. An upward trend — showing improvement from freshman to senior year — can offset a weaker start. Admissions committees understand that students mature academically, and a strong final two years demonstrates the ability you will bring to graduate work.

For professional programs, specific course grades matter more than the overall number. Medical schools scrutinize science prerequisites individually. Law schools weigh the LSAT alongside GPA but give extra consideration to your performance in writing-intensive courses. MBA programs look at quantitative coursework like statistics and economics.

International applicants face additional complexity because grading scales differ by country. A first-class degree from a UK university roughly corresponds to a 3.7+ GPA, while some European systems use scales of 10 or 20. Most US graduate programs publish conversion guidelines, and services like WES provide official GPA equivalency evaluations.
