About This Calculator
The Test Grade Calculator is a free online tool for students, teachers, and parents to quickly compute test scores as percentages and letter grades. Simply enter the number of correct answers and the total number of questions on any exam, quiz, or assignment to get an instant result.
The calculator uses the standard formula: Percentage = (Correct Answers / Total Questions) × 100. The percentage is then mapped to a letter grade using the standard US grading scale: A (90-100%), B (80-89%), C (70-79%), D (60-69%), and F (below 60%), with plus and minus distinctions for finer granularity.
Regional Notes
United States: The default scale reflects the standard US academic grading system widely used in K-12 and higher education. Most US institutions consider 60% as the minimum passing grade (D-).
United Kingdom: UK universities typically use classification degrees (First Class 70%+, Upper Second 60-69%, Lower Second 50-59%, Third 40-49%). GCSEs and A-Levels use a 9-1 scale. The percentage score can be mapped to your local system.
India: Indian schools and universities often use percentage-based grading without letter grades, where 33-40% is the typical pass mark depending on the board (CBSE: 33%, ICSE: 35%, university: 40%). The percentage result is directly applicable.
Frequently Asked Questions
How does the Test Grade Calculator work?
The Test Grade Calculator computes your percentage score by dividing the number of correct answers by the total number of questions and multiplying by 100. It then maps the percentage to a standard letter grade scale from A+ to F. Results include a bar chart and pie chart showing the correct versus wrong answer breakdown.
What grading scale does the Test Grade Calculator use?
The calculator uses the standard US grading scale: A+ (97-100%), A (93-96%), A- (90-92%), B+ (87-89%), B (83-86%), B- (80-82%), C+ (77-79%), C (73-76%), C- (70-72%), D+ (67-69%), D (63-66%), D- (60-62%), and F (below 60%). A passing grade requires 60% or higher.
How do I calculate my test grade?
To calculate your test grade, divide the number of points you earned by the total points available, then multiply by 100 to get a percentage score. For example, if you scored 18 out of 20, your percentage is (18/20) × 100 = 90%, which corresponds to an A- grade.
Is 27 out of 40 a passing grade?
27 out of 40 equals 67.5%, which is a D+ grade. Since the passing threshold is 60% (D-), 27 out of 40 is a passing grade. However, grading scales may vary by school, teacher, or country, so always verify with your institution.
What grade is 7 wrong out of 40?
If you got 7 wrong out of 40, you scored 33 correct. This gives a percentage of (33/40) × 100 = 82.5%, which corresponds to a B- grade on the standard scale.
Is 75 out of 80 an A?
Yes, 75 out of 80 equals 93.75%, which is an A grade on the standard scale (93-96% range). This is an excellent score.
Can I change the grading scale?
The current version uses the standard US grading scale. If your school uses a different scale such as a 10-point system or a pass mark of 50% instead of 60%, you can manually compare your percentage against your institution's scale using the percentage result shown.
