Time value of money is usually calculated with compound interest. Using the same formula as above to compute the same $2,000 at 10% for one year - but this time compounding interest quarterly,. The real money is made by investors who sit patiently through short-term volatility to realize long-term compounding gains. That said, there may be no better time to start investing than today. The longer someone invests, the more likely Wall Street is to simultaneously mitigate risk and increase returns. Real values are more important than nominal values for economic measures, such as gross domestic product (GDP) and personal incomes, because they help ascertain the extent to which increases over.

The nominal value of a commodity bundle tends to change over time. In contrast, by definition, the real value of the commodity bundle in aggregate remains the same over time. The real values of individual goods or commodities may rise or fall against each other, in relative terms, but a representative commodity bundle as a whole retains its. In this regard, both parties should agree that the money has value. Store of Value – Money has to hold its value for a definitive period of time, which is what makes it possible for it to be a medium of exchange. This means that you must be able to store it and use it at a later time, in other words, it holds its value over time.

A dollar today isn’t the same as a dollar tomorrow, that’s the time value of money. Risk and return are expecting a dollar risked to earn more than a dollar.

The time value of money and risk and return are two core concepts in personal finance. Luckily, each boils down to a pretty simple statement.

Editor's Note

What Is the Time Value of Money?

The time value of money means your dollar today is worth more than your dollar tomorrow because of inflation. Inflation increases prices over time and decreases your dollar’s spending power.

Risk and return say that if you are to risk a dollar, you expect gains of more than just your dollar back. For each unit of risk you take on, you expect a slightly higher return.

Even though these money concepts are easy to simplify, I want to dig a bit deeper into each of them.

Time Value of Money

Today’s dollar is worth more than tomorrow’s because of inflation (on the side that’s unfortunate for you) and compound interest (the side you can make work for you).

Inflation increases prices over time, which means that each dollar you own today will buy more in the present time than it will in the future. This is why investing is so important.

Inflation is reported on an annualized basis. That means that to invest a dollar today, you’d have not only to expect to exceed inflation but also have some wiggle room to account for the uncertainty of the future cash flow.

Over time the stock market beats out inflation. So if you put the same amount of money in a savings account and investment account, the money invested would be worth far more than the money sitting in the savings account.

Opportunity Cost

For every choice made, there are choices sacrificed. The decision to go to college is a simple example of opportunity cost.

Choosing to attend means you are giving up four years worth of salary you would have earned at a job and four years of work experience (future payment.)

Of course, you hope that by choosing to go to school, you will make more money over your lifetime than if you don’t attend. So it’s a gamble, but a calculated one that hopefully has a more significant pay off eventually than if you had chosen not to go to college.

The time value of money varies and involves an opportunity cost.

That means that if you’re putting $1000 in a savings account to save for a house, you may be giving up an opportunity to grow that money in an investment account.

For example: Calculating the time value of your money will tell you that instead of investing, you should be paying down your 24% APR credit card debt that’s costing you hundreds a month.

Compound Interest

What’s the point of investing money if it won’t grow faster than inflation? You’d be better off spending it now when it has a higher value. That’s where the compound annual interest rate comes to the rescue.

A standard bond returns a flat percent of the face value each year, which is simple interest. In that case, if you got a 5% annual interest rate on a $1000 face value bond, you’d get $50. That’s not bad, but it’s not where the magic lies.

When you’re looking at investments like stocks, you expect the annual percentage rate to be 5% a year, or 7% if you count dividends. If you have a $100 stock that increases 5% by the end of the year, you have $105 in that compounding period.

By the end of year two, it’s grown another 5% and is worth $110.25 ($105*1.05). While that’s only an extra 25 cents, in this case over long periods and with substantial dollar amounts, that can end up being a lot of money.

It’s possible to compound interest monthly or even daily – this is called continuous compounding. This means that your balance grows by a small amount every instant.

Time Value of Money Calculator

Assuming you have a financial calculator or access to the internet, it’s pretty easy to see how much your current cash flow would be worth tomorrow, though you do have to make some assumptions.

If you’re not a money nerd like me and don’t have a financial calculator sitting next to you, there are plenty available online. Here’s one from fncalculator.com. If you’ve never used one before, here’s a step by step break down of what the terms mean:

PV: This means present value. Enter how much money you have today. If you have a $20 in your wallet, enter 20.

Rate: This is the rate of growth. If you’re calculating how much inflation will be, you can use a number like 3%. If you’re trying to see what your money will grow if you’re getting a 7% real (after inflation) rate of return, use 7%. You put in the whole number (7) instead of the actual decimal number (0.07).

PMT: This means payment. It’s the amount that you’re adding to the PV per period. Think of it as a monthly contribution to an IRA (assuming you’re doing monthly compounding).

Periods: The number of times you’re compounding your money. It’s essential to keep in mind how extended a period is – are you compounding weekly, monthly, or annually?

FVA: This is your future value. If you’re trying to calculate what your money will be worth in the future once you’ve made payments and had to compound, you’ll see your answer here.

If you’re trying to reverse engineer what a future sum of money is worth today with deflation, you start with this number. And if you want to put your math hat on, the following formula is to calculate this:

Using the Time Value of Money Formula

Are you bored yet? I promise you it’s essential. With those variables, you can answer questions like these:

How much money would I need to save starting today if I wanted to have $1,000,000 in 20 years, assuming a 6% growth after inflation?

Enter 6% for rate, nothing in payment, future value $1,000,000, net present value $0, and 20 periods. Please, try it yourself! You could do this for anticipated future costs like weddings, school costs, buying a house, or anything else you want to save for.

If I start with nothing today and put away $100 a month, what will I have in 10 years if I get a 4% growth after inflation?

Here we use net present value 0, payment 1200, rate 4, ten periods, and solve for future money. Again, I recommend you try it yourself, but I get $14,407. This kind of question is great for seeing where you’ll be if you start today.

I go through these kinds of hypotheticals occasionally because it’s always fun to watch how my money would work for me.
