GPA Calculator

Calculate your semester and cumulative GPA on a credit-weighted 4.0 scale

Grade points and eligible courses vary by school. Check the scale below against your institution’s policy. Your inputs stay in your browser.

A+ and A are 4.0. P, W, and I are excluded; F credits count in the denominator. Results are rounded to 3 decimal places. Course-repeat replacement and weighted high-school GPA are not included.

The 4.0 grading scale used here

A+: 4.0 · A: 4.0 · A-: 3.7 · B+: 3.3 · B: 3.0 · B-: 2.7 · C+: 2.3 · C: 2.0 · C-: 1.7 · D+: 1.3 · D: 1.0 · D-: 0.7 · F: 0.0 · P: Excluded · W: Excluded · I: Excluded

What this tool does

Estimate a semester GPA from letter grades and course credits using a common 4.0 scale. The calculator weights each course by its credit value, so a four-credit class counts more than a one-credit class. You can also combine this term with a previous cumulative GPA and GPA-credit total. Course information is processed locally without an account.

Common use cases

  • Check a semester GPA from final letter grades
  • Try expected grades to see their effect on your average
  • Combine a new semester with a previous cumulative GPA

How to use it

  1. Enter each course’s credits and letter grade; names are optional.
  2. To include prior results, enable cumulative GPA and enter your previous GPA and GPA credits.
  3. Select Calculate GPA and review the average, quality points, and counted credits.

Input and output example

Input: 3 credits of A, 3 of B−, 4 of C+, and 3 of F
Output: 29.3 quality points divided by 13 GPA credits gives approximately 2.254.

Important notes

  • A+ and A use 4.0 points. P, W, and I are excluded. F contributes zero points but its credits still count.
  • The displayed GPA is rounded to three decimal places. Your institution may truncate or round differently.
  • Enter up to 30 courses with credits greater than 0 and up to 100 per course, using up to two decimal places.
  • Institution-specific repeat replacement, excluded courses, and Honors/AP high-school weighting are not applied. A rounded previous GPA makes the cumulative result an estimate.

Frequently asked questions

Is GPA a simple average of grade points?
Only if every course has the same credits. One credit of A and three credits of B give (4×1 + 3×3) / 4 = 3.25.
Can I calculate a weighted high-school GPA?
This tool uses a college-style 4.0 scale with credit weighting. It does not add Honors, AP, or IB bonus points or convert from percentage or 4.3 scales.
