Grade Calculator

If all assessments have equal weight (or you leave weights blank), the calculator computes a simple arithmetic mean. This is equivalent to all weights being equal — for example, 25% each for four equally weighted assessments.

A final exam worth 40% of your grade has a major impact. Scoring 60% on a 40-weight final pulls your average down significantly even if earlier grades were high. Conversely, a strong final exam performance can rescue a lower cumulative grade. Use the calculator to model 'what if' scenarios.

Standard letter grade cutoffs: A: 90–100%, B: 80–89%, C: 70–79%, D: 60–69%, F: below 60%. Some institutions use + and - grades (A+ = 97–100, A = 93–96, A- = 90–92). Cutoffs vary by institution — always check your course syllabus.
