GPA Calculator, Free and Online
A GPA calculator converts your letter grades and credit hours into a single grade point average instantly. This one supports the 4.0, 5.0 and 10.0 scales plus percentage marks, updates your GPA live as you add courses, and includes degree classification, a what-if projector and semester history tracking, entirely inside your browser with nothing uploaded anywhere.
GPA, short for Grade Point Average, is the number colleges, scholarship committees and employers actually look at first. Working it out by hand means converting every letter grade to points, multiplying by each course's credit hours, adding those up, and dividing by total credits, a process that gets tedious and error prone once you have more than a few courses across several semesters. This free GPA calculator tool does that math instantly and correctly every time. Pick your grading scale first, since a 3.5 means something different on a 4.0 scale than it does on a 5.0 or 10.0 scale, then add each course with its grade and credit hours. Your GPA, total credits and quality points update live, no calculate button needed. Pro Mode adds degree classification against real academic honor bands, a what-if calculator for planning future semesters, and a semester-by-semester history tracker with a running cumulative GPA.
Every course contributes grade points times its credit hours to the total, then that total is divided by all credit hours combined. A high grade in a low credit course moves your GPA less than the same grade in a high credit course.

2GPA Terms, Quick Reference
The detail that trips up the most students is treating GPA and CGPA as interchangeable. Your GPA for a single hard semester can dip while your CGPA barely moves, because CGPA is an average of everything you have ever taken, not just the current term. This is exactly why a strong first year matters, a few rough semesters later on have less room to pull your CGPA down once there is a large body of earlier credits behind them.
3Where the Letter Grade and GPA System Actually Came From
The A to F scale almost every GPA calculator is built around has a specific, well documented birthplace, and it is not where most people guess. According to Mount Holyoke College's own library and archives, the college introduced the first real letter grading system in 1897, and it originally ran A through E, with E standing for failure, there was no F at all. That version lasted barely a year. Administrators replaced E with F in 1898, largely because parents kept reading E on a report card and assuming it meant Excellent rather than a failing grade. The revised, more symmetrical scale spread from there, and by the 1940s the letter grade system paired with the now familiar 4.0 point scale had become the standard across American colleges and high schools, eventually giving rise to the GPA calculations this tool automates.
