- Click the ‘Calculate’ button.
- View the results below the calculator.
Formula & Methodology
The calculator multiplies the number of columns by the number of rows to give you the total number of cells. It also calculates the total number of non-empty cells based on the average fill rate of Excel worksheets.
Real-World Examples
Example 1: Small Dataset
Let’s say you have a dataset with 5 columns and 3 rows. The calculator will show you have 15 total cells and, assuming an average fill rate of 60%, about 9 non-empty cells.
Example 2: Large Dataset
For a larger dataset with 100 columns and 50 rows, the calculator will show you have 5000 total cells and, with the same fill rate, about 3000 non-empty cells.
Example 3: Irregular Dataset
If you have a dataset with 7 columns and 4 rows, the calculator will show you have 28 total cells and, with the average fill rate, about 17 non-empty cells.

Interactive FAQ
What if my data is not evenly distributed?
The calculator uses average fill rates, so it may not be perfectly accurate for unevenly distributed data. For better results, use Excel’s COUNTA function on your actual data.
Can I use this calculator for other purposes?
Yes, you can use it to estimate the size of any grid-like data, not just Excel worksheets.
