Frequently Asked Questions

Everything you need to know about grade calculations.

Multiply each category grade by its weight percentage, add all the weighted scores together, then divide by the total weight. For example: Homework 95% × 20% + Exams 80% × 50% + Projects 90% × 30% = (19 + 40 + 27) / 100 = 86%.
Dean's List requirements vary by school, but most universities require a semester GPA of 3.5 or higher (out of 4.0). Some institutions set it at 3.7 or require all A's and B's.
In most US schools, a D (60–62%) is the minimum passing grade for individual courses, though many programs require a C or better (70%+). Graduate programs often require a B (80%+) to pass.

Convert each letter grade to grade points (A=4.0, B=3.0, etc.), multiply each by the course's credit hours, sum all the products, then divide by total credit hours. Our GPA calculator does all of this automatically.
Start from your kindergarten start year. Add the grade number to find the school year you were in that grade. For example, if you started kindergarten in Fall 2005: Grade 1 = 2006–07, Grade 6 = 2011–12, Grade 12 = 2017–18. You can reverse-engineer it from your high school graduation year: subtract 12 from grad year to get your Kindergarten year, then add whatever grade you want.
"E" on a calculator means scientific notation — it represents ×10 to a power. So 3.5E6 = 3,500,000 and 2.1E-3 = 0.0021. Calculators switch to this format automatically when numbers are too large or too small to display normally. On scientific calculators, lowercase "e" also refers to Euler's number (≈2.718), the base of natural logarithms.

How to Use the Grade Calculator

Our free grade calculator supports three modes: Simple Grade for quick percentage-to-letter conversions, Weighted Grade for courses with multiple assignment categories, and GPA Calculator for semester or cumulative GPA tracking.

Simple Grade Calculator

Enter the total points possible and the points you earned. The calculator immediately shows your percentage, letter grade, and GPA equivalent using the standard US grading scale.

Weighted Grade Calculator

Add each graded category (Homework, Quizzes, Midterm, Final, etc.), enter your score and the category weight. The tool computes your final weighted average automatically. Weights do not need to sum to exactly 100% — the calculator normalizes them.

GPA Calculator

Add each course you are taking or have taken, select its letter grade, and enter the number of credit hours. The calculator computes your cumulative GPA on the standard 4.0 scale used by most US colleges and universities.
