EW 62: When and how calculation of cash basis adjustment required
or “Calculating cash basis adjustments when changing financial reporting methods”

You could also call this:

“How to calculate adjustments when changing money tracking methods”

You can use a special math formula to figure out how much money you need to adjust when you switch between different ways of keeping track of your money. This is called a cash basis adjustment.

The formula looks like this: adjusted income minus adjusted expenditure minus previous income plus previous expenditure.

Adjusted income means different things depending on your situation. If you’re starting to use the cash basis method, it’s the money you would have earned if you had been using this method from the beginning. If you’re stopping the cash basis method, it’s the money you would have earned if you had been using a different method from the start.

Adjusted expenditure is similar. If you’re starting the cash basis method, it’s the money you would have spent if you had been using this method from the beginning. If you’re stopping the cash basis method, it’s the money you would have spent if you had been using a different method from the start.

Previous income is simply the money you’ve already earned from this financial arrangement in past years.

Previous expenditure is the money you’ve already spent on this financial arrangement in past years.

By using this formula, you can figure out how much you need to adjust your finances when you change your accounting method.
