Weighted Average Calculator

Calculate weighted averages for grades, investments, surveys, and more. Perfect for situations where some values contribute more than others.

Calculation Results

Enter values and weights, then click Calculate to see the weighted average

Our Weighted Average Calculator allows you to determine the weighted average of multiple values based on their weights with ease. If you are computing your grades, a financial portfolio's returns, a survey's results, or analyzing your performance, this makes the task of determining which values contributed more to the average, much easier.

A weighted average allows for more emphasis on certain values based on their weight. It is more ideal for use when not all values or data points are given the same weight - for example, calculating test scores with credits, stock portfolio returns, or customer satisfaction ratings.

What is a Weighted Average?

A weighted average is a mathematical way to govern the importance of each value. Each number in your data set is multiplied by its weight and aggregated with respect to the total of all weights. This is useful for compute weighted average results which account for real-world situations where some elements are more valuable than others.

For example, if you are working out grades for an assignment or exam that has been given an unequal weight, the Weighted Average Calculator will give you an accurate reflection of your real performance.

Formula for Weighted Average

The formula for weighted average is:

Weighted Average = Σ(Valuei × Weighti) / ΣWeighti

Where:

Valueᵢ = individual data point
Weightᵢ = corresponding weight

This formula for weighted mean simply multiplies each value by its weight, and then averages them, rather than giving you a more imprecise measurement from the simple arithmetic mean.

FAQs

A Weighted Average Calculator is used to calculate averages when different data points matter at unequal rates and can be useful in scoring, or evaluating different data points in weight situations.

To compute weighted average, we multiply every value by its weight, sum the products, and divide that by the sum of all weights.

The formula for weighted mean is: Weighted Mean = 𝛴(Value x Weight) / 𝛴Weight

A weighted average should be utilized when the components in the set are differentially important - such as when some subjects, investments, or survey response options carry more weight than others.

Yes! The Weighted Average Calculator may be used for GPA calculations, financial analysis, or any situation which utilizes a weighted measurement.

Weighted averages are useful in providing a more representative value of performance or data, by incorporating varying levels of importance for components and subsequently should be employed in making important decisions and analysis.
