How 80 Percent Converts to GPA

Grades also affect your GPA.

Here is how 80 percent usually converts:

• B = 3.0 GPA
• B- = 2.7 GPA

Some schools give extra GPA points for honors or AP classes.
Other schools do not.

Because of this, the same 80 percent score can affect GPA differently.
Always check your school’s official GPA scale.

How to Calculate 80 Percent on a Test

To calculate a percentage, divide the points you earned by the total number of points and multiply by 100.

Formula:

Percentage = (Points Earned ÷ Total Points) × 100

Example

If you score 32 points out of 40:

32 ÷ 40 = 0.80

0.80 × 100 = 80%

So, 32 out of 40 is an 80% grade.

You can use our Grade Calculator to calculate your percentage and letter grade automatically.

Before determining your letter grade, you should make sure your percentage is accurate. An easy grade calculator can instantly calculate percentages from earned and total points.

80% Grade Examples

Here are some common ways to get an 80% score:

Score	Percentage
80 out of 100	80%
40 out of 50	80%
32 out of 40	80%
24 out of 30	80%
16 out of 20	80%
8 out of 10	80%

The number of points can change, but the percentage stays the same when you earn 80% of the available points.

What 80 Percent Means for Your GPA or Transcript

Most transcripts show letter grades, not percentages.

If 80 percent equals a B or B- at your school, that is what appears.
That letter grade then affects your GPA.

One B grade will not hurt your academic record.
Your overall GPA depends on all your classes together.

For parents, this means one 80 percent score is rarely a problem by itself.

Percentage to Letter Grade Conversion

Here is one common U.S. grading scale:

Percentage	Letter Grade	Typical GPA
90–100%	A	4.0
87–89%	B+	3.3
83–86%	B	3.0
80–82%	B-	2.7
77–79%	C+	2.3
73–76%	C	2.0
70–72%	C-	1.7
60–69%	D	1.0

This is an example of a common scale. Your school may use different percentages, ranges, and samples.
