GradeAnchor is a small set of free grade calculators for students and teachers in the United States. Each one answers one question clearly and shows the math behind the answer.

Who runs GradeAnchor
GradeAnchor is run by Mujeeb Ullah from Mardan, Pakistan. It is an independent website. It is not part of any school, college or testing organization.
How the calculators are built and checked
- They use the grading rules most US schools follow: the standard letter scale (A from 90%, B from 80% and so on), the plus/minus scale, and the 4.0 GPA scale.
- Every result shows the formula with your own numbers, so you can check it yourself or compare it with your syllabus.
- Before a calculator goes live, it is checked against worked examples calculated by hand and a set of automated tests, including unusual inputs like blank rows, letter grades and half points.
- Each calculator is tested on phones and computers, in light and dark mode, and with accessibility checks for keyboard and screen reader use.
What GradeAnchor does not do
- No sign-up or account.
- No storing your grades. The calculations run in your browser and nothing you type is sent to our server.
- No selling or sharing of personal information. Read the Privacy Policy for details.
