Today we will build a mortgage payment calculator using excel. But we will not build a boring excel sheet, we will build a mortgage calculator that is easy to play with.
A mortgage payment is a monthly installment that you pay towards a loan. Any mortgage loan will typically have,
- loan amount
- duration of the loan (also called as tenure of mortgage) in years
- interest rate (APR) per year
Given these 3 parameters, we can easily determine the monthly installment amount (this will be the same amount for all months during loan tenure)
We are going to use Excel’s form controls (more on this below) to build a mortgage payment calculator like this:
Why you should not be boring and use the form controls
A form control is a button or check box or scrollbar or some other click-able thing you see in Windows. Do you know that you can add the very same controls to Excel spreadsheet to make the it interactive?
For example,
- instead of asking a user to enter “yes” or “no” in a cell, you can ask them to click a check box.
- instead of taking “age” in a cell, you can use a scroll bar and set the values from 0 to 100.
This way of gathering inputs is more fun, engaging and interactive.
Now that you find form controls hot and attractive, lets proceed and make a house loan payment calculator.
How is mortgage payment calculated?
As I said above, any mortgage (or housing loan) will have 3 parts – loan amount (p), loan tenure (n) and annual interest rate (r).
Given the values of P, N and R, we can find the monthly payments using Excel’s PMT formula like this:
=PMT(R/12,N*12,P)
[Related: PMT formula syntax & examples]
[Related: Amortization Schedule in Excel]
We are dividing interest rate (R) by 12 since R is annual interest rate and we make monthly payments.
We are multiplying loan duration (N) with 12 since we are going to make monthly payments.
Making the mortgage calculator in Excel
We will use scroll-bar controls to take numeric inputs required (P,N and R) for the payment calculation. And we feed these values to PMT formula to find the monthly installment amount.
Step 1: Add a Scroll-bar Control
We will use this scroll bar to take “loan amount” input. To keep it simple, we will ask users to enter input in ‘000s. So, if the loan is $120,000, the input should be 120.
First add a scroll-bar form control to your excel sheet. To do this go to Developer Ribbon > Insert > Scroll-bar Form Control in Excel (related: enable developer toolbar in Excel)
Add a Scroll-bar Control
Once selected, just add the control to spreadsheet by clicking anywhere.
Step 2: Set Properties for this Scroll-bar
To set the properties for the scrollbar control, right click on it and go to “format control” option. Now go to “Control” tab.
Here set minimum and maximum values for the scroll bar. To keep our model simple, just set minimum as 35 and maximum has 500.
Also, select a cell to link the scrollbar. When you do this, excel links the scroll bar to the selected cell. So whenever scroll bar is updated the cell gets updated too (and vice-a-versa). See this illustration:
Step 3: Add Remaining Scroll bars
Repeat the same steps for 2 other scroll bars. One for interest rate and one for loan tenure.
Make sure you set the minimum and maximum values in a reasonable range.
Step 4: Plug the values in to PMT formula
Now that the scroll bars are ready, just write the PMT formula. Assuming you have linked scroll bars like this:
- Loan amount in cell A1
- Interest rate in cell A2
- Loan tenure (years) in cell A3
The formula will be,
=PMT((A2/12)%,A3*12,A1)
Remember, PMT returns value in negative numbers (as it is the amount we need to pay, not get). But you can make it positive (for display purposes) by multiplying it with -1 like this = -PMT((A2/12)%,A3*12,A1)
Step 5: Play with your Model
Now your mortgage payment calculator is ready. You can play with it by testing various combinations and finding monthly payments. You can easily see what happens when you increase loan tenure or decrease interest rate.

Here is the excel mortgage payment calculator file. Download and play with it.
Bonus – Making an Amortization Schedule
You can easily extend this model to add an amortization schedule to see how much of each monthly payment is towards principal and how much is for interest.
- You can calculate principal portion for any month using PPMT formula like this
=PPMT(R/12,M,N*12,P). Here “M” is the month for which you want principal amount. - You can calculate interest portion for any month using IPMT formula like this
=IPMT(R/12,M,N*12,P).

Do you love form controls?
Do you use form controls in your spreadsheets? I find them pretty intuitive and use them wherever I can. I have made many complex spreadsheet models easy to understand and work with by just adding form controls. The beauty is that, they require no programming or anything. You just add them and link them to a cell.
What about you? Do you love form controls? Where do you use them most?

Its possible to display up to 4 text values.
Have a look at the screen shot of an example that I had posted way back at the EHA and figure out how its done !

With Excel 2010 you can use Conditional Formatting to apply custom number formats which can display text. (In older versions you can only modify text color and cell background color, but not number formats.) Using CF allows for an even larger number of different display values.

Hey,
Thanks, this helps. But how do you do it for multiple values where there is a huge amount of non repeating text?
@Soumya
The only way to do more than 4 values is to make the Pivot Table manually with formulas, of course then it isn't a Pivot table
You can of course do it with VBA
You may want to have a look at this description of how to do it here: http://www.clearlyandsimply.com/clearly_and_simply/2011/06/emulate-excel-pivot-tables-with-texts-in-the-value-area-using-vba.html

[...] Pivot Tables take tables of data and allow the user to summarise and consolidate the data at the same time. This is a great and very fast method of analysis but is restricted to handling mathematical functions on the value field resulting in numerical summaries. – read more [...]

There is a very good way actually for handling text inside values area.
First you create a special column on the very left side and call it ID, and put unique ID (numbers only), and then create a pivot table with:
Row Labels and Column labels as you like, and in the Values labels use the unique ID number.
Move the unique ID number (copy paste) somewhere to the right and use vlookup to load the data you need using the ID as reference.
It is a bit longer way but for me it works perfectly to combine values as you like in any moment.
hope helps.

Thank you! I finally understand pivot tables thanks to your clear, concise explanations and examples.
Good Day. This is exactly what i have been looking for. However when i try it on my pivot table or even when i try to recreate this exercise using the sample worksheet, i get this error:
"Microsoft Excel cannot use the number format you typed. Try using one of the built-in number formats."
Same thing here, Excel quite did not like the format in my PowerPivot. Any clues as to what may be going on? Thanks.
I have the same thing happening on my end. I'm running a normal pivot table on a .xlsm file.
@Danzi
What format did you use?
can you post the file ?
pls. help in table there is name, pan. amount. i have to make pivot table for example
NAME PAN AMOUNT
MR.X AAAAC1254T 500.00
MR.Y AAABR1258C
MR.A CFVDE2458T
MR.Z AAVCR12548C
MR.X AAAAC1254T
MR.Z AADCD245T
pls. help in table there is name, pan. amount. i have to make pivot table for example
NAME PAN AMOUNT
MR.X AAAAC1254T 500.00
MR.Y AAABR1258C 1000
MR.A CFVDE2458T 2000
MR.Z AAVCR12548C 5451
MR.X AAAAC1254T 45564
MR.Z AADCD245T 4500
how to get pivot tabe so i get PAN no. against Name.
I found an easy way to get text values in pivot table.
I create an other worksheet in wich each cell has a formula that copy the pivot table. The trick is that the formula does a lookup for the numbers in the pivot table.
The formula looks like that:
=IF(ISNUMBER(table!A1);VLOOKUP(table!A1;Code!$A$1:$B$65;2);IF(ISBLANK(table!A1);" ";table!A1))
Code is a worksheet where there is a liste of text /numbers correspondance.
As a bonus The new sheet is easier to format
Additional trick:
In my case, i encoded differents codeid with a power(2, codeId-1) so that summing then is equivalent to concatenate them.
1-A
2-B
4-C
8-D
yields :
5 - AC
14 - BCD
Hi
I want to ask if pivot can display dates in pivot field. As in a column i have customers and in row different items i want to know there last purchase date. anyone help in this??
Hello Guys, Need your help
I am doing some analysis of the cycle time of the product i.e how much time a product takes from manufacturing to the central warehouse.
I have batch numbers for the product and against them i have to pull out the diff. dates
Like the base date is from where the manufacturing start. So i have the batch number,against it's manuf. date. Now i have to pull out the date when it was quality released.
I have the quality released data but the data have duplicates, like i will have two dates or may be three for the same batch. So my main objective is to pull out the date which is latest among them.
BATCH NO. DATE of Mfg. DATE of Quality release
A1 12/4/2014 (HERE I HAVE TO PULL value)
Next Sheet
BATCH NO. DATE of Quality Release
A1 14/5/2014
a2 23/5/2016
A1 12/5/2014
A1 13/6/2014
From this sheet i have to pull up the latest date format of date here is dd/mm/yyy
TIA
