Frugal Fridays- Keeping Track of Expenses

While you know how much normally about you have coming in for income, do you know how much you spend? This includes using store cards and credit cards. In our house we have started using a Google Sheets so either of us can access it at any time.

We have different categories by expenses for example

Food
Fast Food
Gas
Credit Card Payments
Animal Supplies
Fun
Household Supplies
Utilities/Rent
Medical
Gifts

You can add or remove any categories you don't need to use. January is our 2nd full month of doing this and we are finally getting the hang of it.

Do you have a way to  keep track of expenses? I'd love to hear about them.
