How to use this tool

  1. Add your courses

    For each class, pick the letter grade, enter the credits or hours, and mark it Honors or AP/IB if it is.

  2. Add your history (optional)

    Enter your current GPA and credits to get a cumulative GPA, and a target to see what you need next term.

  3. Read your GPA

    See your unweighted GPA, your weighted GPA and, if you set a target, the GPA you need on your next credits.

Example

Four high school classes, two of them advanced.

Input

  • A, 3 credits, regular
  • B+, 4 credits, regular
  • A-, 3 credits, honors
  • B, 3 credits, AP

Result

  • Unweighted GPA: 3.48
  • Weighted GPA: 3.83
  • 13 credits

The 4.0 grade scale

  • A+ or 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
  • Some schools count A+ as 4.33; check your school's scale.

How GPA is calculated

Multiply each grade's points by the course's credits to get quality points, add them up, and divide by the total credits. An A in a 4-credit class (16 points), a B+ in a 3-credit class (9.9) and a C in a 3-credit class (6) give 31.9 ÷ 10 = 3.19.

Credits matter: a grade in a 4-credit class moves your GPA more than the same grade in a 1-credit class.

Weighted vs unweighted GPA

An unweighted GPA treats every class the same, so the maximum is 4.0. A weighted GPA adds points for harder classes. A common scale adds 0.5 for honors and 1.0 for AP, IB and dual-enrollment classes, so an A in AP Calculus counts as 5.0.

High schools differ in how they weight classes, and many colleges recalculate GPAs their own way. College GPAs are almost always unweighted.

Raising your GPA

The more credits you've completed, the slower your GPA moves. With a 3.0 over 60 credits, getting to 3.2 takes a 3.6 average over your next 30 credits. Use the target field to see what's realistic before the term starts.

Common errors

  • Averaging grades without credits

    A plain average gives every class the same weight. Enter each course's credits so the result matches your transcript.

  • Adding honors points to a college GPA

    Colleges rarely weight classes. Leave every course on Regular for a college GPA.

  • Averaging two GPAs

    A 3.8 over 15 credits and a 3.0 over 60 isn't 3.4. Use the cumulative fields so each GPA counts by its credits.

Frequently asked questions

How do I calculate my GPA?

Turn each letter grade into points (A = 4.0, B = 3.0 and so on), multiply by the course credits, add them up and divide by the total credits.

What's the difference between weighted and unweighted GPA?

Unweighted GPA counts every class out of 4.0. Weighted GPA adds extra points for honors (usually +0.5) and AP or IB classes (usually +1.0), so it can go above 4.0.

Is a 3.5 GPA good?

Yes. A 3.5 is a B+/A- average and above the typical US college average. Highly selective colleges often see applicants at 3.8 and above.

How do I calculate my cumulative GPA?

Enter your current GPA and the credits it covers, then add this term's courses. The calculator combines them, weighting each by credits.

Can I raise my GPA from 2.5 to 3.0?

It depends on your credits. With 30 credits at 2.5, a 3.5 over the next 15 credits gets you to 2.83, and over 30 credits to 3.0. Use the target field to try your own numbers.
