How the weighted grade calculator works
Multiply each graded score by its weight, add those products, and divide by the sum of the weights you included. A 90% score at 60% weight and an 80% score at 40% weight give 86%.
Average grades without weights
With equal weights, add the percentages and divide by the number of scores. If assignments have different maximum points, select Total points to divide total earned by total possible.
Blank grades and zeros
Blank scores are excluded from your current average. Enter 0 for a graded zero. If completed weights add up to less than 100%, the result represents the graded portion.
