Use your school catalog or syllabus if it uses weighted, honors, AP, pass/fail, or plus/minus rules differently.

Formula steps

  1. Convert each letter grade to grade points on the selected 4.0 scale.
  2. Multiply grade points by course credits to get quality points.
  3. Divide total quality points by total credits.

Frequently asked questions

Plain-language answers about when to use the tool, what it does with your inputs, what to double-check, and how privacy works.

When should I use the GPA Calculator?

Use it when your task matches one of these common needs: Estimate term GPA from several courses. Compare how credit hours change the GPA impact of each grade. It works best when you already know each course credit value and letter grade you want included, plus your school scale if it differs from the common unweighted 4.0 scale.

What is the GPA Calculator doing with my inputs?

In plain language: Each course grade is converted to grade points, multiplied by credits for quality points, then total quality points are divided by total credits. The examples on the page are there so you can compare your inputs with a course schedule example before copying the answer.

What do the main GPA Calculator inputs mean?

Course credits: the credit hours or units for each class. Higher-credit classes change the GPA more. Course grade: the letter grade for that class, such as A, B+, C-, or F. Zero-credit rows: a row with 0 credits is ignored, which lets you calculate fewer than four classes. 4.0 scale: the calculator uses a common unweighted scale where A+ and A are 4.0, A- is 3.7, and F is 0.

How should I read the GPA Calculator answer?

Read the headline answer, then check the supporting lines and examples to understand how the calculator got there. If one input changes, rerun the tool and compare the new answer instead of guessing.

What should I double-check before trusting the answer?

This is a planning estimate on a common unweighted 4.0 scale. Schools can use different grading scales, weighted courses, pass/fail rules, repeats, and plus/minus policies, so use your school scale or transcript for official GPA. Also check whether your school weights honors, AP, IB, repeated, pass/fail, incomplete, or transfer courses before using the estimate as a planning number.

How does a credit-weighted GPA work?

A credit-weighted GPA gives more influence to higher-credit classes. The calculator multiplies each class grade point value by its credits, adds those quality points, then divides by total credits.

What grade points does this GPA Calculator use?

It uses a common unweighted 4.0 plus/minus scale: A+ and A count as 4.0, A- as 3.7, B+ as 3.3, B as 3.0, down through D- as 0.7 and F as 0. Your school may use a different table.

Why does a 4-credit class affect GPA more than a 1-credit class?

Credits act like weight. A 4-credit A adds four times as many quality points as a 1-credit A, so changing the grade in a high-credit class moves the total GPA more.

Can I use this for official transcript GPA?

Use it for planning and checking the math, not as an official record. Official GPA can depend on school-specific grade points, weighted classes, repeated courses, pass/fail classes, transfer credits, and transcript rules.

Does the site save what I enter?

No. The calculator runs in your browser tab. Your recent answers stay only on the page while you use it, and they are not sent to a server.
