Grade & GPA Calculator Toolkit
Weighted grade, GPA, grading-curve, and class-rank calculators for students, teachers, and academic advisors.
Grade & GPA Calculator Toolkit
Eight calculators covering the full arc of academic math — from a single weighted assignment grade to a multi-year cumulative GPA. No external data, no APIs: every formula runs locally against well-established grading conventions.
What it does
- Weighted grade — combine homework, quizzes, exams, and any other graded category into an overall percent and letter grade
- Final exam needed — solve for the score required on a final to hit a target overall grade (and flag when it's mathematically out of reach)
- GPA calculator — credit-weighted GPA from a term's courses, with an optional honors/AP bonus scale
- Grade converter — move between percent, letter grade, and GPA points on the standard US 10-point scale
- Cumulative GPA — merge a prior GPA with a new term's results
- Required term GPA — solve for the GPA needed this term to hit a target cumulative GPA
- Percentile rank — find where a score lands in a class, either from the full list of scores or from a mean/standard deviation
- Grade curve — apply a curve using four common methods: flat addition, square-root, linear-stretch-to-top-score, or shift-to-target-mean
Why it's useful
"Grade calculator" is one of the single highest-demand calculator searches that exists — bigger than mortgage or loan calculators. Students recompute these numbers constantly, and teachers use the curve and percentile tools every time they grade an exam.
Every response carries a disclaimer: grading scales, GPA point values, and curve methods vary by school and instructor — always verify against your syllabus or institution's official policy.
