About School Grade Calculators

Last updated June 9, 2026

Every term, students re-derive the same algebra at 11 p.m.: what do I need on the final? This site keeps that algebra solved and rearranged for the questions that actually come up — the GPA you have, the grade you need, and how category weights turn scores into a final mark.

Tools for the term

The current set is 6 calculators: GPA Calculator, Final Grade Calculator, Weighted Grade Calculator, Grade Percentage Calculator, Cumulative GPA Calculator, and Study Time Calculator.

Match it to your syllabus

Category weights, credit hours, and grading scales differ by school, so all of them are inputs here rather than baked-in assumptions. The formula behind each result is printed next to it, which makes the output easy to verify against a syllabus — or to show your work with.

Your school has the final say

These are grade estimates, not official academic figures — your school’s published grading policy and your instructor are the authority on your actual grade.

Found a grading bug?

If a result here disagrees with hand-worked math, email [email protected] — that’s treated as a serious bug and fixed.
