The Grade Calculator is a simple yet powerful online tool designed to help students calculate their overall course grades, GPA, and the score they need on their final exam to reach their academic goals. Whether you’re in high school, college, or university, this calculator allows you to determine your weighted average and stay on top of your academic performance without the hassle of manual calculations.

How Does the Grade Calculator Work?
Our Grade Calculator uses a weighted average formula to determine your overall grade. Simply add each assignment, test, or project along with its percentage weight, and the calculator automatically computes your current average.
If you’re preparing for finals, use the Final Exam Calculator section to find out what score you need on your last exam to reach your target grade. Enter your current grade, desired grade, and how much your final exam is worth — and get instant results.
The calculator also supports both letter grades (A, B, C, D, F) and numeric percentages, automatically converting between them using standard GPA equivalents.

A Brief History of Grading Systems:
The concept of grading has evolved for centuries. In the 18th century, universities like Yale and Harvard used ranking terms such as “Optimi” or numerical scales like 1–200. Later, in 1887, Mount Holyoke College introduced the modern letter grading system (A, B, C, D, E) — which eventually became today’s standard after “E” was replaced with “F” to represent failure.
Although grading systems vary across institutions and countries, the A–F letter grading scale remains the most recognized worldwide. It provides an efficient and standardized way to assess academic performance and compare results across different courses or schools.
