Weighted Average Calculator

A weighted average is a mean in which each value has a different weight (importance). Values with a higher weight influence the result more than those with a low weight.

Multiply each grade by its weight, add the products, then divide by the sum of the weights. For example, 9×3 + 8×2 + 10×1 = 53, divided by 6 (the weights) = 8.83.

A simple mean treats all grades equally, while a weighted mean accounts for the importance of each. When all weights are equal, the two means coincide.

For grades with coefficients (for example in exams), for ECTS credits at university, for assessments where some parts count more, and in finance and statistics.

Use each subject grade as the value and the number of credits as the weight. Average = sum of (grade × credits) divided by the total credits of the session.

Weights reflect relative importance: the coefficient of the exam, number of credits, class hours or the percentage of the final grade. Only the ratio between them matters, not the absolute values.

No. The weighted average is always between the smallest and the largest value entered, regardless of the weights.

Enter each grade with the subject’s number of credits as the weight. The result is the session’s weighted average, usually used for scholarships and rankings.
