The formula of personal finance is known to many people: Savings = Income – Expenses Further reading: What is savedroid and how can you use it?.

This equation is comprised of three core elements: Income, Expenses, and Savings. The formula is really simple in order to save you need to have an income which exceeds your expenses.

So logically, the more money you make, the more you’ll save. However, not everyone can make more. On the other hand, everyone (I repeat, EVERYONE) can save.

But sometimes you are willing to save and you earn more than your ordinary level of expenses, but you can’t. How is it possible? Let’s look at an example: Your usually spend 500$ per month, you earn 700$. So as per formula You should save 700-500=200$. but you can’t save. Mathematically it means there is some extra element on the right of the formula which is not very evident at first glance.

Hidden element in personal finance formula

Savings = Income – Expenses – X.  

And the extra element X is the result of zero savings. Wiping away the 200$ and leaves you with no savings. It’s a result of your bad spending behavior. In fact 59% of Americans state their number one fear is running out of money and have no savings in their pocket for some emergency situation. But even in this case of fear they don’t control X well enough. An average American lacks self-control when it comes to showcasing saving habits and the way of controlling the finances.
