Results are mathematical estimates based solely on the values entered. They are not financial, investment, tax or legal advice, nor an offer or recommendation of any financial product.

How Weighted average works

What it calculates

Multiplies each value by its weight and divides the weighted sum by total weight.

Formula and methodology

Use it for portfolios, average costs and combined metrics.

Media = Σ(valor×peso) / Σpesos

Practical example

Reproducible example: use this page’s initial values (Value 1: 100 · Weight 1: 60% · Value 2: 120 · Weight 2: 40%) and press Calculate. Then change one variable at a time to see how it affects the result.

Factors that change the result

Weights must correctly represent the relative importance of each value.

Context: This tool belongs to the Financial Math category and is designed to solve a specific mathematical intent using user-entered values.
