How do you calculate weighted average?
To find a weighted average, multiply each number by its weight, then add the results. If the weights don’t add up to one, find the sum of all the variables multiplied by their weight, then divide by the sum of the weights.
What is weighted average with example?
For example, say an investor acquires 100 shares of a company in year one at $10, and 50 shares of the same stock in year two at $40. To get a weighted average of the price paid, the investor multiplies 100 shares by $10 for year one and 50 shares by $40 for year two, and then adds the results to get a total of $3,000.
