We most often think of money in terms of its monetary value. And this obviously makes sense in a lot of ways. Unfortunately, however, monetary value does not capture the whole picture and can lead to bad decisions and worse outcomes. That is why, especially as physician, we need to consider the time value of money.

## What is the time value of money?

They say money can buy anything but time. And this is true at the very end of your life.

But during your life, that’s not really true at all. Money absolutely buys you time. That’s exactly what financial freedom is. It is you buying back all of your remaining time to spend exactly as you please.

It seems obvious reading it like this. But understanding this is so absolutely powerful. This realization completely changed my mindset and outlook in life. That’s a big statement but it’s true. I never really considered that I’d be able to live life completely on my terms until I was old and retired.

Financial freedom completely disproves that myth.

In this sense, the time value money may be even more important that its actual monetary value. And we need to be using the time value of money to assess the decisions we make much more regularly than we actually do.

So how can we do this?

## How to calculate the time value of money

In my mind, there are two ways to go about doing this…

### 1. The hourly wage method

This way is pretty simple and fits into our usual perspectives of money as holding monetary value.

To gauge the time value of money in this way, simply figure out what your hourly wage is as a physician. To do this:

- Figure out your average monthly post-tax income over the past year
- Divide that number by the average number of hours that you worked each month over the past year
- I wouldn’t use side gig income here and would stick to just your physician income

There you go. That is your hourly wage. It’s not important that this is totally spot on. You just want a good average number.

Now you have the monetary value of 1 hour of your time in a very concrete and immediate form.

*I want to make a quick and important distinction. When you make this calculation,* *you may be happy with your hourly wage. Or feel that you are very underpaid. If you feel underpaid, use strategies like these to increase your compensation.*

### 2. The “time delayed” method

This method is a bit different and more outside of our usual concepts of money. But stick with me…

Let’s say you use my FIRE calculator and figure out that you want a $4.5 million nest egg to retire.

You plan to retire in 25 years. So, using the same calculator, you figure out that you need to save $100,000 annually. This assumes you have no savings to start with and make an annual 5% return.

Doing this, you will end up with $4.7 million at the time of your proposed retirement, meeting your goals.

Essentially, this means that $100,000 is equal to 1 year of savings. The time value of that $100,000 is roughly 365 days. That is, 365 days that you need to work and save to balance your FIRE equation.

Inversely, 365 days of your time is worth roughly $100,000 using this method.

*Now, I know that this calculation is not perfect. And it’s not meant to be. There are tons of other variables. But the point is to give you a new frame of reference about how your money and time interact. More precisely, you want to know when some amount of money is worth your time, or not.*

## Using the time value of money in your life

Ok, so now we have two ways that we can use to calculate the time value of money. But what do we do with these calculation in our lives as physicians? And how can they help us make better decisions – both financially and otherwise?

I think the best way to illustrate this is through examples.

### Scenario #1

You are an internal medicine doctor making $250,000 post-tax annually for 40 hours/week of work. An hour of your time is thus worth roughly $120 ($250,000/40 hours per week * 52 weeks).

A moonlighting opportunity comes up and offers $200/hour. Now, this may be an opportunity worth considering. Now, you add in all the other variables. Working one extra moonlighting shift may therefore be worthwhile as long as it doesn’t diminish from other areas of your life like family, friends, and personal well-being.

Another moonlighting opportunity offering $100/hour would be a non-starter.

Same goes for any side gig opportunity that offers you less money per hour than this!

### Scenario #2

You are a pediatrician making $175,000 post-tax annually, working an average of 40 hours each week. You seek to have a $2 million nest egg when you retire in 25 years. And you determine this because you estimate $7,000 in monthly expenses in retirement (calculated using this method). In this case, $7,000 buys roughly a month of your time.

You are trying to figure out if real estate investing is worthwhile for you.

After research and education, you estimate that you can make an annual 14% cash-on-cash return from investing in duplexes in your local market. You would need a roughly $50,000 initial investment (down payment and closing costs) for each property. Thus, your annual cash flow from each property is $7,000. *This ignores the other 4 important ways that cash flowing rental properties make you money.*

In this scenario, every property that you buy according to your criteria buys you 1 month of your time over the span of one year.

You therefore plan to buy one such property every year for 12 years. After 12 years, you will have bought one year of your time via annual cash flow from rent. And the best news is that this cash flow continues year after year. So you actually just bought your financial freedom!

### Scenario #3

Let’s say that you are the doctor in the above example used in calculation method #2. Your goal is to save $100,000 annually to reach your goal nest egg in time.

Now, let’s say that you face a choice. You can:

- Buy a Tesla for $50,000 or
- Save and invest that money

Essentially, that $50,000 is equal to 1/2 year of savings ($50,000/$100,000 annual savings goal).

The time value of that Tesla/$50,000 is roughly 183 days. That is, 183 days more that you need to work and save to rebalance your FIRE equation.

Is it worth it to you? For some, the answer is yes. For others, the answer is no. But you need to ask the right question to make the right decision. And most of the time we don’t!

## The importance of the time value of money

I hope these scenarios illustrate just how powerful the time value of money is and how it can help guide you through some impactful decisions!

The goal is life is to live in a manner aligned with our goals and our values. To do this however, we need accurate representations and measurements for our goals and values.

Unfortunately, the monetary value of money only tells part of the story. And the less important part at that. Remember, money is just a tool for the good that it can create. And financial freedom can create a whole lot of good for you, your loved ones, and the world!

*What do you think? Do you ever consider the time value of money? What does it mean to you? *Let me know in the comments below!

I would caution against giving a well studied and recognized financial concept like āTime Value of Moneyā a completely different definition because you then handicap yourself in going back to the conceptās actual meaning and the way you use it to discount future cash flows. The post gives examples of the substitution of personal work time for a given dollar sum but thatās a moving target for physicians because we move from a period in residency and medical school where our time equates to very little money in the moment but is ābuyingā degrees and qualifications which have a very high value in future earnings.

These are excellent points and considerations. Iām not saying my way of thinking about it is perfect or even right. But this perspective helped me to get out of the time for money loop that I was stuck in for so long. Holding it can help others the same way!

What is your definition or perspective?

Thank you for the reply. I don’t think of money spent in terms of the time it takes to earn it but maybe sometimes think of it in terms of opportunity cost (e.g. a simpler version of your scenario 3: would I enjoy the Tesla more or enjoy investing the extra $50K in another syndication?) but that plays on my own enjoyment of investing and probably wouldn’t help others. The financial concept of “Time Value of Money” on the other hand is something I think about a lot because it’s at the core of evaluating investments through discounted cash flow analysis, to quantifying opportunity cost and to defining time preference. I am not saying it isn’t worthwhile to think about the time it took to make money when deciding on a purchase just that the label “time value of money” already has a recognized meaning.
