Plan: reach a target GPA

Optional: enter the GPA and credits you've already earned to fold them in.

You need a 3.5 GPA across these 13 credits to reach a 3.5 cumulative GPA.

Add each course with its letter grade and credit hours; this GPA calculator multiplies each grade's points by its credits, sums them, and divides by total credits. It shows both the unweighted 4.0-scale GPA and a weighted GPA that adds +0.5 for honors and +1.0 for AP or IB courses you mark.

The formula

GPA = Σ(grade points × credits) ÷ Σ(credits)

An A is 4.0, A- 3.7, B+ 3.3, and so on. Multiply each by the course's credit hours, add them up, and divide by the total credits to get the grade-point average.

How to use it

  1. 1

    Add your courses

    For each class, pick the letter grade and enter its credit hours. A typical course is 3 or 4 credits; use 1 each if you weight them equally.

  2. 2

    Mark honors and AP classes

    Flag any honors or AP/IB course to include the weighted boost (+0.5 or +1.0). The unweighted GPA ignores these flags.

  3. 3

    Read both GPAs

    You get the unweighted GPA (what most colleges recalculate to) and the weighted GPA your transcript reports, plus total credits.

Frequently asked questions

What is the difference between weighted and unweighted GPA?
Unweighted caps every course at 4.0. Weighted adds a bonus for harder classes — typically +0.5 for honors and +1.0 for AP or IB — so a weighted GPA can exceed 4.0.
How many grade points is each letter worth?
On the standard scale an A or A+ is 4.0, A- is 3.7, B+ is 3.3, B is 3.0, and each step down drops about 0.3–0.4 until F at 0.0.
Does a failing grade still count?
Yes. An F contributes 0 grade points but its credits still count in the denominator, which is why one F pulls a GPA down sharply.
