GPA Calculator: Grade Point Average on a 4.0 Scale

How to use the gpa calculator

1. Select a letter grade for each course you completed, or leave it as (skip) to ignore that row.
2. Enter the credit hours for each course (typically 3 or 4 for a standard college class).
3. The GPA, total quality points and total attempted credits update automatically as you type.
4. Leave unused rows blank. Only courses with a selected grade are included in the calculation.

How the 4.0 GPA scale works

The standard 4.0 scale assigns a numeric value to each letter grade. An A equals 4.0, a B equals 3.0, a C equals 2.0, a D equals 1.0 and an F equals 0.0. Plus and minus modifiers shift the value by one third of a point: a B+ is 3.33, a B- is 2.67, and so on. Most colleges cap A+ at 4.0 rather than awarding 4.33.

Your grade point average is the sum of all quality points divided by the sum of all attempted credit hours. Quality points for a single course equal the grade value multiplied by the credits. For example, a B+ (3.33) in a 4-credit course earns 13.33 quality points. If you also earned an A (4.0) in a 3-credit course, that adds 12.0 points. Total quality points: 25.33. Total credits: 7. GPA: 25.33 / 7 = 3.62.

Grade-to-points reference table

This table shows the exact point values this gpa calculator uses for every letter grade on the 4.0 scale.

Some institutions use slightly different rounding conventions. Always check your school catalog if precision matters for academic standing.

Semester GPA versus cumulative GPA

A semester GPA reflects only the courses taken in one term. A cumulative GPA includes every graded course across all semesters. To compute your cumulative GPA manually, add the quality points from every term together and divide by the total credits from every term. Do not simply average your semester GPAs unless every semester had exactly the same number of credits, because that ignores the weighting effect of heavier course loads.

This college gpa calculator handles both cases. For a single semester, enter just those courses. For a cumulative figure, enter all courses from all terms into the available rows.

Common mistakes when calculating GPA

The most frequent error is treating all courses equally regardless of credit hours. A 1-credit lab and a 4-credit lecture do not pull your GPA the same amount. The 4-credit course has four times the weight. Another mistake is including pass/fail or audit courses. Those carry no grade points and should be excluded from both the numerator and the denominator.

Students sometimes assume an A+ raises their GPA above 4.0. On the standard 4.0 scale used here, A+ is capped at 4.0. Finally, rounding too early introduces errors. Keep full precision through the division step and round only the final result to two decimal places.

What GPA do colleges and employers look for?

Graduate programs commonly require a minimum 3.0 cumulative GPA, while competitive programs may expect 3.5 or higher. Many employers who request transcripts use a 3.0 threshold as a screening filter, though work experience often outweighs grades after the first job. Honors designations like cum laude typically start around 3.5, with summa cum laude reserved for 3.9 or above.

If you need to figure out what score you need on a final exam to reach a target GPA, a final grade calculator can help you work backward from your goal.
