GPA Calculator (4.0 Scale)

Work out your GPA on the 4.0 scale from letter grades and credit hours. Choose your school’s scale and, if your school uses one, add a weighted bonus for honors or AP classes.

Guide

How GPA is calculated

Each letter grade has a point value. Multiply the points by the credit hours for each course, add them up, and divide by the total credit hours.

GPA = sum(points × credit hours) ÷ sum(credit hours)

Example: A in a 3-credit course (12.0), B+ in a 4-credit course (13.2), C in a 3-credit course (6.0) and A- in a 2-credit course (7.4) make 38.6 quality points over 12 credits, a GPA of 3.22.

The 4.0 scale used here

A+ and 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. This is a widely used university scale (for example, Indiana University’s official scale). Some schools give A+ 4.3, and some do not use plus and minus grades; switch the scale to match yours.

Weighted GPA

Many high schools add extra points for honors, AP or IB classes, but the amount varies by school (often +0.5 or +1.0). Add a bonus only if your school uses one; the calculator then shows both your unweighted and weighted GPA. A bonus is never added to an F.

Common questions

Do pass/fail classes count?

Usually not. Pass, satisfactory and withdrawn grades normally have no point value and are left out of GPA. Leave them out of the calculator too.

What GPA is a B+ average?

On this scale a B+ is 3.3, so straight B+ grades give a 3.3 GPA.

My school’s GPA is different. Why?

Schools differ on A+ values, plus/minus grades, weighting and repeated courses. Use the scale options to match your school, and treat the official transcript as final.
