When is savings equal to investment

And we see here this identity that national savings, which is often denoted with a capital S, is equal to investment. And if that isn't intuitive for you at first, just think about it at a kind of human scale. If I am saving things and I am putting it into a bank, that bank will then lend that money that can be used for investment. And we can break this down even more if we wanna think about taxes. So let's just say T is equal to taxes. So let's just think about the private economy first.

So if we think about the national income minus consumption spending, and then folks have got to pay their taxes. So minus taxes. And then where do those taxes go? Well, they go to the government, so they stay in the economy. So notice, I'm not changing this equation, I'm just subtracting taxes and then adding taxes. And then I subtract from that government spending. These two equations are equivalent and this is going to be equal to our investment in our closed economy.

Now, if you look at this left-hand side right over here, you could view this as private savings. This is the national income, minus how much is being consumed, minus how much is being paid to the government. Download all slides. Sign in Don't already have an Oxford Academic account?

A general rule of thumb is saving should be short-term while investing should be long-term. Also, keep in mind for both saving and investing that when risk goes down, liquidity goes up and vice versa.

We save for purchases and emergencies. Saving money typically means it is available when we need it and it has a low risk of losing value.

Understanding different investment vehicles, what they are for, and how to use them is imperative to being successful. We use specific vehicles that allow for growth. If our children have plus years before they go to college, we can invest monthly in a vehicle like an education savings account ESA or a plan.

To start, the biggest and most influential difference between saving and investing is a risk. You save when you put money into a savings account like a money market account or Certificate of Deposit CD. It has little risk of loss of funds but also has minimal gains. When you save, you are usually able to pull that money out when you need it or after a period of time.

When you invest, you have the potential for better long-term gains or rewards, but also the potential for loss. You risk more in investing for a larger return, but your potential loss can be large as well. It is important to review your goals to figure out which option is best for each one, saving or investing. Choosing incorrectly could cost you a lot of money in fees or loss of potential income earned through investing.
