**Introduction to the MOD Function**

**Function Objective:**

**Returns the remainder after a number is divided by a divisor.**

**Syntax:**

**=MOD(number, divisor)**

**Arguments Explanation:**

Argument | Required/Optional | Explanation |
---|---|---|

number |
Required |
Dividend or the number that has to be divided. |

divisor |
Required |
Integer number, by which you want to divide the dividend. |

**Return Parameter:**

**The remainder of a division.**

**9 Suitable Examples of Using MOD Function in Excel**

**1. Using MOD Function to Find the Remainder**

In the first section of the uses of the MOD function in Excel, weâ€™ll find out the remainder from a division. In the picture below, there are 3 columns with dividends, divisors and remainders. Weâ€™ll find out the remainders in **Column C**.

**đź“Ś**** Steps:**

âž¤ In **Cell D5**, type:

`=MOD(B5,C5)`

âž¤ Press **Enter**, autofill the rest of the cells in **Column D** and youâ€™ll get all the remainders at once.

There are some facts to notice with the** MOD** function while determining the remainders. The remainder will always follow the +/- sign of divisor and it doesnâ€™t matter if a dividend is positive or negative.

Another important fact is if you divide a number with a decimal then the function will return a wrong output which is illustrated in Row 9 as the value 32 is divisible with 1.6 and the remainder should have been 0 but here the function has returned the value 1.6. So this function is useful only with the integer divisors and you cannot expect the function to return an accurate +/- sign either.

**2. Determining Odd or Even Number with MOD Function**

By combining** IF** and **MOD** functions together, we can determine odd or even numbers so easily.Â There are some numbers in **Column B**, and in **Column C**, weâ€™ll show the messages which numbers are odd and which ones are even.

**đź“Ś**** Steps:**

âž¤ In **Cell C5**, we have to type:

`=IF(MOD(B5,2)=0,"Even","Odd")`

âž¤ Press **Enter**, autofill the entire column with **Fill Handle** and youâ€™re done.

**3. Performing Calculation on Only Odd Rows with MOD Function**

The picture below represents the marks of a studentâ€™s exams in two terms which have been defined by** Test 1** and** Test 2.** Test 1 results are lying in odd rows and Text 2 results in even rows. Letâ€™s assume, we want to know the marks of **Test 1** for all subjects.

**đź“Ś**** Steps:**

âž¤ In the output **Cell D16**, the related formula will be:

`=SUM((MOD(ROW(C5:C14),2)=1)*(D5:D14))`

âž¤ Press **Enter** and the function will return the total marks for all subjects in Test 1.

**đź”Ž How Does This Formula Work?**

âž¤ **ROW** function extracts all the row numbers of the range of cells **C5:C14** and will return an array of:

**{5;6;7;8;9;10;11;12;13;14}**

âž¤ **MOD** function finds out only odd-numbered rows from these values and will return:

**{TRUE;FALSE;TRUE;FALSE;TRUE;FALSE;TRUE;FALSE;TRUE;FALSE}**

âž¤ Finally, the **SUM **function sums all the values by following the logical value- **TRUE** only and ignores another logical value- **FALSE**.

**4. Performing Calculation on Only Even Rows with MOD Function**

Now to find the total marks of **Test 2**, we have to calculate the data for even rows only. The procedure is the same as the previous method but here as weâ€™re extracting the even rows only, so in the **MOD** function, the remainder will be 0 here to find out the even-numbered rows.

**đź“Ś**** Steps:**

âž¤ In **Cell D16**, the related formula will be:

`=SUM((MOD(ROW(C5:C14),2)=0)*(D5:D14))`

âž¤ After pressing **Enter**, youâ€™ll get the calculated sum for all subjects in **Test 2.**

**5. Carrying out Calculation on Every n**^{th}** Row with MOD Function**

^{th}

If we have to perform calculations for every n^{th} row in a column, then we have to combine **SUMPRODUCT, MOD, SEQUENCE and ROWS** functions together. In the picture below, **Column B **contains a number of integer values. We want to make a sum of every 3rd row from that column.

**đź“Ś**** Steps:**

âž¤ In the output **Cell E13**, the related formula will be:

`=SUMPRODUCT((MOD(SEQUENCE(ROWS(B5:B23)),3)=0)*(B5:B23))`

âž¤ Press** Enter** and the resultant value will be shown right away.

**đź”Ž How Does This Formula Work?**

âž¤ Here, the **ROWS** function returns the total number of rows- 19 from the range of cells **B5:B23.**

âž¤ **SEQUENCE** function returns the serial of 19 numbers starting from 1 and the array will look like this:

**{1;2;3;4;5;6;7;8;9;10;11;12;13;14;15;16;17;18;19}**

âž¤ **MOD** function then divides all these 19 numbers with 3 and will return the logical value- **TRUE** for all divisions where no remainder was found. So, the return values from this step will be:

**{FALSE;FALSE;TRUE;FALSE;FALSE;TRUE;FALSE;FALSE;TRUE;FALSE;FALSE;TRUE;FALSE;FALSE;TRUE;FALSE;FALSE;TRUE;FALSE}**

âž¤ Finally, the **SUMPRODUCT** function extracts data from the specified rows where the logical value** TRUE **is assigned and then returns the sum of those values.

**6. Carrying Out Calculation on Every n**^{th}** Column with MOD Function**

^{th}

In the case of performing calculations on every n^{th }column, we cannot use **SEQUENCE **and **ROWS** functions here. Rather we have to use **COLUMN** functions inside the **MOD** function now. For example, in Row 5 in the picture below, there are some integer values and weâ€™re going to determine the sum of every 3rd column in that row.

**đź“Ś**** Steps:**

âž¤ In our output** Cell E8**, the formula will be:

`=SUMPRODUCT((MOD(COLUMN(B5:T5)-COLUMN(B5)+1,3)=0)*(B5:T5))`

âž¤ After pressing **Enter**, youâ€™ll get the resultant value as 172.

**7. Counting Cells Containing Odd or Even Numbers with SUMPRODUCT and MOD Functions**

By combining **SUMPRODUCT and MOD** functions, we can count the cells containing odd and even numbers. In the picture below, **Column B** lies with several integer values and in Cells D10 and D13, weâ€™ll determine the total counts of odd and even numbers respectively.

**đź“Ś**** Steps:**

âž¤ In **Cell D10**, you have to type:

`=SUMPRODUCT((MOD(B5:B20,2)=1)*1)`

âž¤ Press** Enter **and youâ€™ll get the total count of odd numbers in **Column B**.

âž¤ Now copy the formula, replace 1 with 0 for the **MOD** function to find out the even numbers, and input the modified formula in **Cell D13**.

âž¤ Press **Enter** and youâ€™ll get the total count for even numbers as well right away.

**8. Using MOD Function to Highlight Cells**

We can use the **MOD **function to highlight specific rows or columns in Excel spreadsheets. For example, in the following picture, we want to highlight the marks of all subjects for **Test 1** only. As the marks of Test 1 are lying in odd-numbered rows so we have to use the MOD function while formatting to specify those rows.

**đź“Ś**** Step 1:**

âž¤ Select the range of cells **C5:D14** first.

âž¤ Under the **Home** tab, select the **More Rules** command from the Conditional Formatting and **Highlight Cell Rules** drop-downs in the **Styles **group of commands.

**đź“Ś**** Step 2:**

âž¤ In the **New Formatting Rule** dialogue box, select the **â€śUse a formula to determine which cells to formatâ€ť** from **Rule Type** options.

âž¤ Go to the **Rule Description** box and type the following formula there:

`=MOD(ROW(C5:C14),2)=1`

âž¤ Press** Format **option. Another dialogue box will appear.

**đź“Ś**** Step 3:**

âž¤ From the **Fill **tab, choose any color you want to highlight the cells

âž¤ Press **OK** and youâ€™ll be brought to the previous dialogue box again.

**đź“Ś**** Step 4:**

âž¤ Now youâ€™ll be shown a preview of the highlighted cell in the **New Formatting Rule** dialogue box. Press** OK** and youâ€™re done.

Like the picture below, youâ€™ll find your highlighted rows with the selected color.

**9. Data Validation with MOD Function in Excel**

Data validation in Excel is very important when you have to input accurate data or values in the proper format. If you give a wrong input then the cell will not accept that value and will show an error message. In the picture below, we have to input the heights in centimeters in **Column C** and the input data will accept integer values only. If you input a decimal value, an error message will be shown. So weâ€™ll now learn how we can assign these criteria for **Column C**.

**đź“Ś**** Step 1:**

âž¤ Select **Cell C5** first.

âž¤ Under the **Data** ribbon, choose the **Data Validation** command from the **Data Tools **drop-down. A dialogue box named **Data Validation** will appear.

**đź“Ś**** Step 2:**

âž¤ Under the **Settings** tab, select **Custom **in the** Allow** box for **Validation criteria**.

âž¤ In the formula box, type:

`=MOD(C5,1)=0`

âž¤ Press **OK**.

**đź“Ś**** Step 3:**

âž¤ Use **Fill Handle** from **Cell C5** to copy the cell format into the next **cell C6**.

âž¤ Enter a height in integer value in **C5** and youâ€™ll be shown no error message as youâ€™ve just put an integer value.

**đź“Ś**** Step 4:**

âž¤ Now try to input a height in decimal value in **Cell C6** and youâ€™ll be shown an error message.

So, this is how you can assign a fixed format of a data entry in a certain range of cells.

**Alternative to the MOD Function to Find the Remainder**

We have an alternative to the **MOD** function which is basically a customized algebraic formula to find the remainder from a division. In the picture below, weâ€™ll find the remainders in **Column D** based on the dividends and divisors from the other two columns.

**đź“Ś**** Steps:**

âž¤ In the output **Cell D5**, the related formula will be:

`=B5-(INT(B5/C5)*C5)`

âž¤ After pressing **Enter** and auto-filling the entire column with the **Fill Handle**, youâ€™ll find all the remainders at once.

**đź’ˇ**** Things to Keep in Mind**

đź”ş **MOD** function always returns a similar **+/- **sign as the divisor.

đź”ş The divisor must be an integer value in the MOD function otherwise, you wonâ€™t get the accurate value of the remainder.

đź”ş If the divisor in the MOD function is 0, the function will return a** #DIV/0** error.

**Concluding Words**
