Frequently Asked Questions
Everything you need to know about GPA, how it's calculated, and how our free online GPA calculator works.
GPA stands for Grade Point Average. It is a standardized numerical score that represents a student's academic performance. Each letter grade (A, B, C, etc.) corresponds to a number of grade points. Your GPA is computed by multiplying each course's grade points by its credit hours, summing those products, and dividing by total credit hours. Most US colleges use a 4.0 scale where A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0.
Our calculator uses the standard weighted-average GPA formula (Σ Grade Points × Credits ÷ Σ Credits) and is mathematically accurate for the data you enter. However, individual institutions may have unique policies—such as excluding certain courses, grade replacement policies, or different grading scales. For your official GPA, always refer to your university's registrar.
We support three grading scales: the 4.0 scale (used in the US and Canada), the 5.0 scale, and the 10.0 scale (commonly used in India). You can switch between scales using the dropdown at the top of the calculator. Each scale has its own set of letter grades and corresponding point values, which you can review on our Methodology page.
GPA calculators can differ because they use different grade-to-point mappings (some omit +/- modifiers), different rounding methods, or weighted vs. unweighted formulas. Some include bonus points for AP/honors courses, while others don't. Our calculator uses a standard mapping with +/- modifiers and rounds to two decimal places. See our methodology for full details.
Yes. To calculate your cumulative GPA, enter all courses from every semester you've completed. The calculator will compute the weighted average across all of them. For a semester GPA, enter only the courses from that specific term. You can also use our Semester GPA Calculator guide for more details.
No. All calculations are performed entirely in your web browser using JavaScript. No course names, grades, credit hours, or personal information is ever sent to any server. When you close the page, your data is gone. Read our Privacy Policy for more details.
Yes. This GPA calculator is completely free—no registration, no login, no premium tiers, no hidden charges. You can use it as many times as you want.
Absolutely. The calculator is built with a mobile-first responsive design. It works on smartphones, tablets, laptops, and desktops. The interface adjusts automatically to fit your screen.
No. This is an independent educational tool. The results are estimates based on standard GPA formulas. This tool is not affiliated with any university or educational institution. For your official GPA, check your institution's student portal or request an official transcript from your registrar.
Unweighted GPA uses a standard 4.0 scale for all courses. Weighted GPA awards extra points for advanced courses (AP, IB, honors)—typically on a 5.0 scale. For example, an A in an AP class might count as 5.0 instead of 4.0. Learn more in our Weighted vs. Unweighted GPA guide.
To calculate GPA by hand: (1) Convert each letter grade to grade points, (2) multiply each by the course's credit hours, (3) add up all the products, (4) divide by total credit hours. For a detailed walkthrough with examples, see our How to Calculate GPA Manually guide.
On a 4.0 scale, a GPA of 3.5 or above is generally considered very good (Dean's List level). A 3.0 is solid. Below 2.0 may be considered academic probation territory at some institutions. However, "good" depends on context—your goals, your school's curve, and the competitiveness of your program. Read more in our What is a Good GPA? article.
Yes, there are approximate conversion methods. For example, many institutions consider 90–100% as an A (4.0), 80–89% as a B (3.0), and so on. However, exact conversions vary by institution. See our Convert Percentage to GPA guide for detailed conversion tables and methods.
GPA is one of the most important factors in college admissions. Most selective universities expect a minimum GPA of 3.0 or higher. Your GPA also affects scholarship eligibility, honors programs, and graduate school applications. Learn more in our GPA and College Admission guide.
