What is a Grade Calculator?
A grade calculator is a digital tool that helps students and educators determine academic scores by converting raw marks into percentages or letter grades. It automates the calculation process, eliminating manual errors and saving time. Users input their obtained marks and total possible marks, and the calculator instantly computes the percentage score and corresponding letter grade based on standard grading scales. This tool is particularly useful for tracking academic progress, determining final grades, and setting target scores for future assessments. It's widely used in educational institutions and by individual learners to maintain academic transparency and performance evaluation.

- 80-89%: B
- 70-79%: C
- 60-69%: D
- Below 60%: F
