Student ProjectHi! I'm a student developer building Calculat in my spare time. I was tired of searching for basic math tools and having to click through 10 spammy popups, loan ads, and cookie trackers.

The Grade Calculator allows high school and college students to calculate their weighted cumulative course grade and determine the exact score required on an upcoming final exam or project to achieve their desired target letter grade.
\text{Weighted Avg} = \frac{\sum (\text{Grade}_i \times \text{Weight}_i)}{\sum \text{Weight}_i}, \quad \text{Final Needed} = \frac{\text{Target} - (\text{Current} \times (1 - w_{\text{final}}))}{w_{\text{final}}}Where Grade_i is score in category i, Weight_i is percentage weight, and w_final is the decimal weight of the final exam.
Scenario: Current course average of 85% with a 30% final exam to achieve a 90% A
Current weighted coursework (70% of course): 85% × 0.70 = 59.5 points.
Points needed from final: 90.0 - 59.5 = 30.5 points.
Required final exam score: 30.5 / 0.30 = 101.67%.
In a weighted grading system, different assignments contribute different proportions to your final grade. For example, a 100-point midterm worth 30% has far more impact than ten 10-point quizzes worth 10% combined.
The calculator divides the total weighted points by the sum of entered weights, accurately calculating your current grade average based strictly on completed coursework.
Enter your desired target (e.g., 90% for A- or 93% for A) and your final exam weight. The calculator solves for the exact test score necessary.
The standard US college 4.0 scale is used: A (93-100%, 4.0), A- (90-92%, 3.7), B+ (87-89%, 3.3), B (83-86%, 3.0), B- (80-82%, 2.7), C+ (77-79%, 2.3), C (73-76%, 2.0), C- (70-72%, 1.7), D (60-69%, 1.0), and F (<60%, 0.0).
