Grade Calculator
Calculate your grades with precision. Convert points to percentages, see your letter grade, or find out how many points you need to reach your target grade.
How do you calculate a grade percentage?
Grade percentage is calculated by dividing points earned by total points possible, then multiplying by 100. Formula: Grade % = (Points Earned / Total Points) × 100. For example, if you earned 85 out of 100 points, your grade is (85 / 100) × 100 = 85%. This applies to individual assignments, tests, or overall course grades.
What is the standard grading scale?
The most common grading scale is: 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%), F (below 60%). However, grading scales can vary by institution - some schools use a 10-point scale (90-100 = A, 80-89 = B, etc.) or different cutoffs.
How many points do I need to get an A?
To find points needed for a target grade: Points Needed = (Target % × Total Points) - Current Points. For example, if you have 320 out of 500 total points and want 90% (450 points total), you need 450 - 320 = 130 more points. If fewer than 130 points remain, achieving 90% is impossible. This helps you plan study priorities for remaining assignments.
What is the difference between weighted and unweighted grades?
Unweighted grades use a standard 4.0 scale where A=4.0, B=3.0, C=2.0, D=1.0, F=0. This calculator shows unweighted percentages. Weighted grades give extra points for honors/AP classes (A=4.5 or 5.0). Weighted GPAs can exceed 4.0. Colleges often recalculate GPAs using their own systems. For weighted grade calculations, use our Weighted Grade Calculator.
