About this calculator
Combine grades with different weights into one weighted average.
Formula
Weighted average = sum(grade × weight) ÷ sum(weights).
Example
Four equally weighted grades of 80, 90, 90 and 90 average to 87.5%.
Accuracy
Use the grading scale and rules supplied by your school, college or university. NUMTX provides a mathematical estimate and does not replace an institution's official grade calculation.
