  - The **‘basis’** argument is not equal to 0, 1, 2, 3, or 4.
- [**#VALUE! Error**](https://geekexcel.com/how-to-fix-value-error-in-excel-office-365-with-example/) – Occurs if either:

Let’s look at s0ome practical examples of **COUPDAYBS function** and explore how to use it in Microsoft Excel.

### Example 1:

- We have entered the input values of settlement, maturity, frequency, and basis into the cell range B5: E7.
- Here, in this example, we have selected the input cells B5, C5, D5, and E5 to calculate the number of days.

- Now, you can see the result in the G5 cell.
- You can repeat the same for other input values.
- In another way, you can just drag the cell G5 to G7 so it automatically returns the respective output.

### Example 2:
