What is an 18 out of 30 Grade? Calculate Percentage & Letter Grade
Quick Answer: A score of 18 out of 30 equals a 60% percentage grade. In most US grading systems, this is a D-, representing the lowest possible passing grade.
Getting an 18 out of 30 on a test or assignment means you’ve just met the threshold for passing. It’s important to understand this grade’s significance. Let’s look at the calculation and what a D- means for your academic standing.
Calculating Your 18/30 Score
To convert the raw score “18 out of 30” into a percentage, you divide the score you earned by the total possible points, and then multiply that number by 100.
What Letter Grade is a 60%?
A 60% percentage sits at the very bottom of the passing grades, corresponding to a D-.
Letter Grade | Percentage Range | Is 18/30 (60%) in this range? |

D- | 60-62% | Yes |
F | Below 60% | No |
Is an 18 out of 30 a Good Grade?
While an 18/30 is a passing grade, it cannot be considered a “good” grade. It shows that you missed 12 out of 30 points, or 40% of the material. This score should be a wake-up call to identify areas of weakness. A consistent pattern of D grades will negatively affect your GPA and may not be sufficient for meeting prerequisites for more advanced courses.
