Which grade calculator do I need?
- “What’s my GPA?” Use the GPA calculator.
- “What’s my grade in this class right now?” Use the class grade tool.
- “What do I need on my final?” Use the final exam tool.
Your GPA, in plain terms
First, every letter grade turns into points on a 4.0 scale. For example, an A is 4.0 and a B is 3.0. Next, each class counts in proportion to its credits. Finally, you divide the total points by the total credits. The GPA tool also handles Honors and AP classes, which count extra in a weighted GPA.
Your class grade, in plain terms
Most teachers group work into categories, such as homework, quizzes and tests. Each category has a weight. So your class grade is the average of your scores, with each one multiplied by its weight. Other teachers simply add up points instead. In that case, your grade is points earned divided by points possible.
Your final exam, in plain terms
The final usually counts for a fixed share of the course, such as 20% or 25%. As a result, you can work out the exact score you need before the exam. For instance, with 84% now and a final worth 25%, you need 68% to finish with an 80%.
Grade calculators for families moving states
Grading scales and GPA rules differ from school to school and state to state. For that reason, these tools use the standard US 4.0 scale and show it on every page. That way, you can compare grades from an old school and a new one on the same basis. Still, ask the new school for its own scale and transcript policy. For more background, College Board explains how GPA works.
Private grade calculators, by design
Everything runs in your browser. In other words, nothing you type is sent or saved, and the tools never ask for a school portal login.
