Weighted Mean Calculator

About This Tool

The weighted mean calculator is a simple yet powerful tool designed to help users accurately compute the average of a set of numbers when different values carry different levels of importance, or weights.

By entering lists of values and their corresponding weights, the calculator performs the necessary multiplication, sums the results, and divides by the total weight to produce the weighted average. This is especially useful in academic grading, financial analysis, survey data, and scientific research.

The tool features a responsive multi-field form allowing users to dynamically add or remove data points. Validation ensures inputs are numeric, non-empty, and that weights are positive numbers. Results are displayed instantly with clear formatting, supporting decimal precision. Additional features include option to copy results, export data, and view calculation history.

Whether you're a student calculating graded assessments, a researcher analyzing weighted data, or a professional preparing reports, this tool simplifies complex calculations, saves time, and enhances accuracy.
