Uses of Interest Calculator:

A interest calculator is used to calculate interest on some principal. Calculating interest in simple calculator is not easy but if we have just to enter Principal,rate and time(per year)then it would be so easy.Therefore, we are going to make a simple interest calculator to understand the simplest concept of Kodular made apps. Here, we are going to use Simple Interest and rate for per annum.

How to make Simple Interest calculator:

3. Now again add a label and set text as Principal and add a text box from UI option in the sidebar. Textbox can be dragged from sidebar, it is located in the last 2nd option in UI options.
4. Repeat this and add two more textbox and labels for Getting input from user for rate and time for getting amount after adding interest.
5.After completing the above steps now add a button which on click will show the result.
6.Now add a horizontal arrangement and set it's default horizontal and vertical align to center and add two label as shown in above image.(Note:Horizontal arrangement will be in Layouts option.)

Now rename the components so that we could easily differentiate between components.
After you have renamed the components we are going to work on the block section.So, just click on the blocks button available on right corner and you will on the blocks editor section.

Blocks Editing:
