Grade Calculator, Free and Online
A grade calculator converts your subject scores and their weights into a single overall average, letter grade and GPA instantly. This one supports weighted categories, six national grading systems, and updates live as you add or edit subjects, entirely inside your browser with nothing uploaded anywhere.
Most real courses are not graded on a simple average, a midterm worth 30 percent and a final project worth 70 percent do not count equally, no matter how good your score was on either one. This free grade calculator tool handles that properly. Add each subject or assignment with its score and its weight, and the overall average recalculates the moment you change a number. Pick from US, UK, Pakistani, Bangladeshi, Australian or Indian grading systems, or switch to plain percentage mode, and the tool converts your weighted average into the matching letter grade or classification automatically. Pro Mode adds a target grade calculator that works backward from a goal, a what-if simulator for testing scenarios before an exam, filters and search across your subject list, a semester GPA planner, and a downloadable PDF report.
Each score is multiplied by its own weight before being added to the total, then the total is divided by the sum of all weights. A 40 percent final exam moves your grade far more than a 5 percent quiz, even with an identical score on both.

2Weighted Grades, Quick Examples
The mistake that trips up the most students is forgetting to update weights when a category changes. If a syllabus lists five quizzes worth 10 percent each and one final exam worth 50 percent, that is only 100 percent when all five quizzes are entered, drop one quiz from your calculator without adjusting the rest and the weighted average will be wrong even though every individual score is correct. Always check that your entered weights add up to 100 before trusting the result.
3Where Grade Classification Systems Actually Came From
The UK's First, Upper Second, Lower Second and Third classification, one of six systems this calculator supports, did not appear as a finished framework. According to the University of Cambridge Mathematics Faculty's own history page, for 157 years, from 1753 to 1909, Cambridge published its Mathematical Tripos results in strict order of merit, dividing students into Wranglers for first class, Senior Optimes for second class, and Junior Optimes for third class. The single highest scoring student each year was crowned Senior Wrangler and treated as something close to a national celebrity, with Cambridge years sometimes remembered by who held that title rather than by the calendar year itself. The public ranked list was eventually dropped in 1909, partly at the urging of mathematician G.H. Hardy, but the underlying class structure, first, second and third, survived and evolved into the classification system UK universities still use today.
