Education Calculators

Grading systems differ by country, by institution and sometimes by department, so these calculators let you set the scale rather than assuming one. Enter your own weightings, your own grade points and your own pass mark, and the arithmetic follows them.

Grades and averages

The GPA calculator handles credit-weighted grade points, and the CGPA to percentage converter applies the conversion factor your institution uses rather than a guessed one. The weighted average calculator is the general case behind both, useful whenever assessments count for different proportions of a module.

What do I need in the final?

The final grade calculator answers the question students actually ask: given the marks so far and the weight of the final, what score does the final need for a target overall grade? It also says plainly when the target is no longer reachable, which is more useful than a number above 100.

The test grade calculator converts a raw score out of a total into a percentage and a letter grade on a scale you set, and the attendance percentage calculator works out how many more classes you can miss before dropping below a requirement.

Reading and study

The reading time calculator estimates how long a word count takes to read or to present aloud, which is the version that matters for a seminar or a video script.
