How to use this calculator

  1. Enter each class with its letter grade and credit hours. Use 1 credit per class if your school does not use credits.
  2. Set the level to Honors or AP/IB if your school weights those classes.
  3. To get a cumulative GPA, enter your previous GPA and the total credits it was based on.
  4. Check your school's own scale — some give A+ a 4.3 or use different weights.

The formula

GPA = Σ (grade points × credits) ÷ Σ credits A/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 Weighted: Honors +0.5, AP/IB +1.0 (not added to an F)

This is the scale most U.S. high schools and colleges use, and the one the College Board describes for converting grades to a 4.0 scale. Policies vary, so your transcript's GPA is the official one.

Worked example

Four classes: A (3 credits), B+ (4), A− (3), C (2)

  1. Grade points: 4.0 × 3 = 12.0; 3.3 × 4 = 13.2; 3.7 × 3 = 11.1; 2.0 × 2 = 4.0.
  2. Total points = 12.0 + 13.2 + 11.1 + 4.0 = 40.3. Total credits = 12.
  3. GPA = 40.3 ÷ 12 = 3.36.
  4. Cumulative example: 15 credits of A (60 points) on top of 45 credits at 3.0 (135 points) = 195 ÷ 60 = 3.25.

The four classes above are the default rows in the calculator.

Frequently asked questions

What is the difference between weighted and unweighted GPA?

Unweighted GPA uses the same 4.0 scale for every class. Weighted GPA adds extra points for harder classes such as Honors or AP, so it can go above 4.0.

How do I calculate cumulative GPA?

Multiply your previous GPA by your previous credits to get points, add this term's points, and divide by the total credits.

Does an A+ count as 4.3?

At some schools. Many cap the scale at 4.0, which this calculator uses. Check your school's policy.

Do pass/fail classes count?

Usually not. Leave them out unless your school gives them grade points.

What GPA do I need to keep U.S. federal student aid?

Schools set Satisfactory Academic Progress rules; many require at least a C average (2.0) or academic standing consistent with graduation requirements. Check with your school's financial aid office.
