GPA Calculator

This gpa calculator 4.0 scale turns letter grades and credit hours into a grade point average. Students use it to check a term GPA, plan the grades they need, and see how each course affects the total. Add your courses, pick a grade for each, and it shows the GPA to two decimal places.

How the calculation works

This tool uses the US 4.0 scale stated clearly below. It does not use plus or minus variants.

  • A = 4.0
  • B = 3.0
  • C = 2.0
  • D = 1.0
  • F = 0.0

The steps are:

  1. Multiply each grade’s points by its credit hours to get grade points.
  2. Add up all the grade points.
  3. Add up all the credit hours.
  4. Divide total grade points by total credit hours. The answer is shown to two decimal places.

Worked example

Two courses: an A for 3 credits and a B for 3 credits.

  1. A (4.0) x 3 credits = 12.0 grade points.
  2. B (3.0) x 3 credits = 9.0 grade points.
  3. Total grade points = 12.0 + 9.0 = 21.0.
  4. Total credits = 3 + 3 = 6.
  5. GPA = 21.0 / 6 = 3.50.

How to use

  1. For each course, pick the letter grade from the list.
  2. Type the credit hours for that course. Use “Add another course” for extra rows.
  3. Click “Calculate GPA” to see your GPA and the full working.

Limits

Grading scales vary by school. This is an estimate from the stated 4.0 scale, not an official transcript. It uses whole letter grades only (A, B, C, D, F) with no plus or minus variants, and it does not weight honours or advanced courses differently. Check your school’s rules for the official figure.

Frequently asked questions

What grades does this gpa calculator 4.0 scale use?
It uses the standard US 4.0 scale: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. There are no plus or minus grades in this tool.

Is this my official GPA?
No. Grading scales vary by school, so this is an estimate from the stated scale. Your school’s transcript holds the official figure.

What if I leave a course blank?
Fully empty rows are skipped. If you pick a grade without credit hours, or type credit hours without picking a grade, the tool shows a clear error instead of guessing.

Can I add more than two courses?
Yes. Click “Add another course” to add as many rows as you need, then calculate once for the whole set.
