Excel allows us to get create a basic timesheet formula with breaks using the **MOD** function. This step by step tutorial will assist all levels of Excel users in creating a basic timesheet formula with breaks.

**Syntax of the MOD Formula**

**=MOD(number, divisor)**

The parameters of the MOD function are:

**number**– a number which we want to divide**divisor**– a divisor, in our example 1.

## Setting up Our Data for the MOD Formula

Let’s look at the structure of the data. Our table consists of 5 columns. The first two are “Work Start” (column B) and “Work End” (column C). The next two columns are “Break Start” (column D) and “Break End” (column E). In the column F (“Working hours”) we want to get working hours, excluding breaks.

* Figure 2. The data structure for the MOD example*

**Calculating the Basic Timesheet Formula with Breaks Using the MOD Function**

In the cell F3, we want to get working hours as a difference between work start and work and (B3 and C3) minus break length (a difference between break start and break end – D3 and E3).

The formula looks like:

**=MOD(C3-B3, 1) - MOD(E3-D3, 1)**

The first MOD function has **number** C3-B3 and **divisor** 1, while the second has **number** E3-D3 and **divisor** 1. When these two numbers are subtracted, we get the working hours.

To apply the MOD function we need to follow these steps:

- Select cell F3 and click on it
- Insert the formula:
`=MOD(C3-B3, 1) - MOD(E3-D3, 1)`

- Press Enter
- Drag the formula down to the other cells in the column by clicking and dragging the little “+” icon at the bottom-right of the cell.

The first MOD function returns 0.3541666 and the second one 0.0208333. When these two values are subtracted the result is 0.333333, which is equal to 8 hours in the cell F3.
