To get the Weighted Average, you divide by the Total of the weights. If we had just averaged the Test scores, the value would be 75.5, a significant difference. For more information about the SUMPRODUCT and SUM functions, see the course summary. Now, you have a good idea about how to average numbers in Excel.

To calculate the weighted average of a data with a Pivot Table, we can add a column to our source data as an intermediate calculation. This is because Excel doesn't provide a function in the Pivot Table that automatically calculates the weighted average.

Weighted Average: For a weighted average exercise price, the per share amount is "weighted" by the number of shares in the associated option. To calculate this average, add $1,000 ($10 x 100 shares) to $8,000 ($20 x 400 shares), then divide by the total number of shares outstanding, or 500 shares.

Calculate Averages Multiply the average for each category by the weight, in decimal, of each category to calculate the final points out of 100. For example, if your test average is 88.2 percent and is weighted 45 percent, the points for your overall grade out of 100 would be 39.69 (which is 88.2 x 0.45).

Calculate average rate of change in Excel. To calculate the average rate of change (the average bicycle speed) in Excel, you can easily do as follows: 1. Select the blank cell besides the cell with last distance, in our case select Cell C7, enter the formula =(B7-B2)/((A7-A2)*24) into it and then press the Enter key.

We then divide the outcome of SUMPRODUCT by the SUM of the weights. And this returns the Weighted Average of 80. SUMPRODUCT is essentially the Sum of Test 1 times its weight, plus the Mid-term times its weight, and so on. To get the Weighted Average, you divide by the Total of the weights.

The formula for finding the weighted average is the sum of all the variables multiplied by its weight, then divided by the sum of the weights. Example: Sum of variables(weight)/sum of all weights = weighted average. 335/16 = 20.9 minutes is the weighted average of the time you spent working out for the month.

Weighted Average Cost Method: In this method, the average cost per unit is calculated by dividing the total value of inventory by the total number of units available for sale. Ending Inventory is then calculated by the average cost per unit by the number of units available at the end of the period.
