What does this template do?
Learn weighted averages by calculating each observation’s value times its weight and dividing the total by total weight.
Weighted contribution equals value times weight. The summary uses SUMPRODUCT of values and weights divided by SUM of weights, guarded for a zero total weight.
Use nonnegative weights for ordinary weighted means. This example does not average percentages with unrelated denominators or replace a missing observation with zero.
The working tab keeps editable inputs separate from formulas, with room for 60 records. The Notes tab explains the method and how to extend the range. All example records are fictional and can be replaced. Download a workbook format to retain formulas, or CSV when you need calculated values only.
What’s inside
- Weighted contribution equals value times weight. The summary uses SUMPRODUCT of values and weights divided by SUM of weights, guarded for a zero total weight.
- 60 prepared record rows with blank-row guards
- Blue input cells, typed dates and numbers, and frozen column headers
- Notes with the method, assumptions, and range-extension instructions
Which tabs does the workbook have?

What formulas does this template use?
This template holds 63 formulas in 101 cells across 2 tabs, so 62% of its cells calculate. They use 7 distinct functions; the longest formula is 160 characters.
| Function | Uses | What it does |
|---|---|---|
IF | 123 | one result when a test is true, another when false |
COUNT | 60 | counts numeric cells |
COUNTIF | 4 | counts cells meeting one condition |
SUM | 2 | adds numbers |
COUNTA | 1 | counts non-empty cells |
OR | 1 | true when any test is true |
SUMPRODUCT | 1 | multiplies matching entries, then adds them |
Counted from the workbook itself. Only functions that Excel, LibreOffice Calc, Google Sheets and Apple Numbers evaluate the same way are used, so the formulas survive every download format.
How do you use it?
- Replace the fictional records in blue cells with your own data. Keep the dark formula cells.
- Use the units stated in the column headers and keep each record on one row.
- Read the calculated columns and inspect the results before using them. Clear unused input rows; keep their formulas.
- The prepared range holds 60 records in rows 11–70. Extend formulas and summary ranges together if you add more rows.
What is it good for?
- Learn weighted averages by calculating each observation’s value times its weight and dividing the total by total weight
- Replacing the labeled fictional records with your own figures
- Checking a calculation before adapting it to a larger workbook
Questions about this sheet
How is the result calculated?
Weighted contribution equals value times weight. The summary uses SUMPRODUCT of values and weights divided by SUM of weights, guarded for a zero total weight.
What assumptions should I check?
Use nonnegative weights for ordinary weighted means. This example does not average percentages with unrelated denominators or replace a missing observation with zero.
Can I add more than 60 records?
Yes. Copy the formula columns into new rows and extend every summary range to include them. Keep inputs and formulas in their original columns.
Are the example records real?
No. All example data is fictional and intended to demonstrate the formulas. Replace it before using the workbook for your own work.
