# GeoGebra Template for Calculating Your Monthly Paycheck

You can use `Spreadsheet` in `GeoGebra` to calculate your income. In Item 2, there’s a template you can follow. At the end of the entry, there’s an example so you can see how you can use the template in practice.

Usually, it’s better to use `Excel` , since it has more built-in tools like charts and formatting options than there are in `GeoGebra`.

`GeoGebra` Instruction 1

### CalculatingIncomein`Spreadsheet`

1.
Open `Spreadsheet` under  `View` in  `Menu`.
2.
Copy the template in the image below. The cells without formulas in them need to be filled with information you get from your exercise. Note that `GeoGebra` doesn’t display the equal sign before each formula, nor the multiplication symbol (*) between the cell names, but you must type them nonetheless.

Example 1

You have a fixed salary of \$$\text{}3900\text{}$ per month. Your normal workweek is 40 hours, and you receive an additional $\text{}40\text{}\phantom{\rule{0.17em}{0ex}}\text{%}$ to your hourly rate when working overtime during weekdays, and $\text{}100\text{}\phantom{\rule{0.17em}{0ex}}\text{%}$ when working overtime on Sundays. One month you work 15 hours overtime during the week and 6 hours overtime on Sundays. $\text{}35\text{}\phantom{\rule{0.17em}{0ex}}\text{%}$ of your salary goes to taxes. What is your net income?

Follow Item 2 and insert the numbers from the exercise. Your spreadsheet should look like the one in the image below.
