GPA calculator

Calculate your GPA on the 4.0 or 5.0 scale from your letter grades and credit hours, leaving empty rows out.

Fill in at least one row. Required fields inside each row are marked with an asterisk (*).

Choose the scale your university uses: 4 or 5 points.
Enter your grades and credits; empty rows are ignored.

Your grade point average (GPA) is a weighted mean, weighted by each course’s credit hours. This calculator works it out on the 4.0 or 5.0 scale from your letter grades and credits, ignoring empty rows automatically.

Formula

GPA = sum of (grade points × credits) ÷ total credits. On the 4.0 scale A = A+ = 4.0; on the 5.0 scale A = A+ = 5.0.

When is this useful?

Use it when computing your term GPA or preparing applications for scholarships or graduate school to know your GPA on your university’s scale.

Worked example

Example using the calculator’s values on the 4-point scale:
A (3 credits), B (4 credits), A- (3 credits), C (2 credits).
Your GPA is about 3.26.
Total credits 12, total points 39.1.

Assumptions

  • The GPA is credit-weighted, not a simple average of courses.
  • On the 4.0 scale A+ equals A (4.0); on the 5.0 scale A+ equals A (5.0).
  • Rows that are empty or missing a grade or credits are ignored.
  • The scale choice must match your university for an accurate result.
  • Results are estimates, not a copy of your official transcript.

Common mistakes

  • Mixing the 4.0 and 5.0 scales or using a scale your university does not apply.
  • Entering a percentage (like 85) instead of a letter grade.
  • Including withdrawn courses in the calculation.
  • Entering zero credits, since a course with no credits does not move the GPA.

Frequently asked questions

Why is A+ worth the same as A on the 4.0 scale?

In most American systems A+ does not exceed the top of the scale, so both map to 4.0. Some universities award 4.33 for A+, so check your own scale.

My university uses a 100-point system, what should I do?

Use the grade average calculator for percentage grades. This GPA calculator relies on letter grades and credit hours.

Does the GPA include pass/fail courses?

No. Pass/fail courses are usually unweighted and excluded, and this calculator skips them because they have no letter grade.

Methodology and review

The calculator sums the points of each letter grade multiplied by its credits, then divides by total credits, ignoring incomplete rows.

Results are estimates; your university’s official records are always the reference.
