“Time is money,” my father used to tell me when I was a boy. He didn’t like how I dawdled with my chores. I didn’t understand what he meant back then. To me, time and money were two very different things. As a kid, I had lots of time but very little money.
Now, as a forty-something man who has written about personal finance for the past decade, I get it. Dad was right: Time is money — and money is time.
This notion is the central lesson of Your Money or Your Life, the personal-finance classic by Joe Dominguez and Vicki Robin. “Money is something we choose to trade our life energy for,” they write. “You are the one who determines what money is worth to you. It is your life energy. You ‘pay’ for money with your time. You choose how to spend it.”
The authors say that because you spend time in order to earn money, you’re also spending time whenever you make a purchase. This has some powerful implications.
- When you treat time as money (and money as time), you can better evaluate how to allocate your dollars and your hours.
- When you know how much your time is worth, you can decide when it makes sense to “outsource” specific jobs.
- When you spend less, you can work less. In a very real way, frugality buys time. But on a deeper level, frugality buys freedom — financial freedom, freedom from worry, freedom to spend your time however you choose.
Because of the time factor, Dominguez and Robin argue that you don’t earn as much as you think you do. You may be paid $33 an hour, but your real hourly wage is less than that. Possibly much less.
How to Compute Your True Hourly Wage
Let’s say we have a friend named Joe and that he’s a plumber. Joe currently makes the national average for his profession, about $53,000 each year. His nominal wage is approximately $25 per hour.
Based on these figures, if Joe the Plumber decides to buy a $500 iPad, he’d need to exchange twenty hours of his time for it. (Twenty hours worked x $25 per hour = $500 total wages.)
Ah, but it’s not that simple. Joe’s real hourly wage isn’t $25 — it’s something lower.
Think about your job. Think of all the things you do and the money you spend that you wouldn’t if you didn’t work. How long does it take to drive to the office? How much does gas cost? Are you required to own a suit or a uniform? Do you have to take vacations to cope with the stress of your career?
Your Money or Your Life lists eight such possible job expenses, including a few which might be applicable to Joe:
- Commuting — Joe’s office is 20 miles from home. Every day, he spends an hour total commuting to and from work in his 2010 Toyota Camry, which costs about 58 cents per mile to operate. His weekly commute costs him five hours and $116 (58 cents times 200 miles).
- Clothing — It doesn’t take Joe extra time to get dressed in the morning, but it does cost him a little extra money. Several times each year, he has to buy new work clothes because the old ones wear out. Maybe he spends $500 annually on work clothes.
- Food — Joe might take a sack lunch if he were on his own, but he works with a partner who prefers fast food. Joe likes McDonald’s and Burger King too, so he’s happy to go along for the ride. Each day, Joe spends about $5 and one hour for lunch.
Each week, Joe’s job costs him about ten extra hours for his travel time and lunch breaks. That’s about 500 hours each year. He’s also shelling out $140 every week on miscellaneous job-related expenses. That’s approximately $7000 per year.
Now that he knows how much time and money Joe spends on the job, he can compute his true hourly wage. The equation is simple.
- First, Joe subtracts his work-related expenses from his annual salary to find his actual earnings. Using the figures above, Joe is actually earning $46,000 per year ($53,000 base minus $7000 for commuting, clothing, and food).
- Next, he computes the total time he spends on his job (including business trips and Christmas parties, etc.). Joe leaves the house at 6:30 in the morning, and doesn’t return until 4:30 in the afternoon, which means he’s devoting 50 hours per week to work, or about 2500 hours per year.
- Finally, Joe divides his actual earnings by the total number of hours he spends each year on work-related tasks.
It takes Joe 2500 hours per year to earn $46,000. His true hourly wage is $18.40. Not bad, but still much lower than the $25 per hour he thinks he’s earning.
A new $500 iPad doesn’t cost Joe twenty hours of work; it costs him 27 hours of work. To earn money for anything he wants to purchase, Joe has to spend 35% more time on the job than he thinks he does. If you were to include taxes in the calculations, things would cost even more!
Note: Joe’s $25 hourly wage is a pre-tax number but his spending is in after-tax money. He probably makes close to $20 per hour after taxes, which means his actual hourly wage is something like $14.16. That’s about half what he thinks it is. That new iPad will cost him 35 hours of work — almost an entire week. I hope it’s worth it!
While most people trade time on the job in order to gain money, this concept can also be applied in reverse. It’s also possible to trade money to buy time.
For instance, I pay an accountant to do my taxes. Not only is he better at this than I am, but it takes him two hours, whereas it might take me twenty. In this case, I’m happy to trade my money to free up more time to write.
Here’s another example: When Get Rich Slowly was growing like gangbusters, my hourly wage was astronomical. At the peak, my time was truly worth hundreds of dollars per hour. Back then, I had more money than time, so it made sense to outsource whatever I could. I hired a housekeeper. I paid somebody to do yardwork. I had an assistant who answered my email. Meanwhile, I channeled my life energy into making more money.
Today, however, my hourly wage is effectively zero. Yes, my investments throw off some income and I make a few hundred dollars per month from my book and the Get Rich Slowly course, but in reality I don’t have an income. (Because I’m financially independent, I don’t need an income.) Today, I have more time than money. As a result, it makes sense to do things myself whenever possible. I don’t have a housekeeper. I do whatever car maintenance I can. I answer my own email. And so on.
How Frugality Buys Freedom
All of this is interesting, but we still haven’t talked about the most powerful product of realizing that time is money and money is time: When you spend less, you can work less and live more. In a very real way, frugality buys time — and freedom.
You can see this idea at work on two levels.
First, because of taxes and compounding one dollar saved is worth more than one dollar spent.
As I mentioned earlier, you buy things using after-tax dollars. If you bought a new $23,000 Mini Cooper, for example, you’d use money left over after paying the government. But in order to get that $23,000, the average American would have to earn $30,000. The other $7000 — in the form of 5-1/2 weeks of work — goes to taxes.
But it gets worse. Every time you spend one dollar you could have invested, you don’t just lose that dollar but any future return you might have earned on it. Assuming typical stock-market growth, one dollar would have a value of $1.93 ten years from now — and $7.20 in thirty years.
When you combine the effects of taxes and compounding, the results are remarkable. On average, each dollar an American spends represents $2.57 of value in ten years or $9.57 in thirty years. (If you live outside the U.S., the consequences of spending that dollar are probably even greater.)
The bottom line? The opportunity cost of spending one dollar today is ten dollars you might have had in retirement. By carefully guarding your dimes, you turn them into future dollars.
There’s a second way in which frugality buys freedom time.
As you know, I believe profit margin (or saving rate) — the percentage of your income that goes to saving and investing — is the most important number in personal finance. Profit doesn’t just remove the wall of worry from your life, but it also buys time — both now and in the future.
When you spend less today, you need to earn less today to fund your lifestyle. It takes less time to earn enough to support $20,000 in annual spending than it does to support $40,000 in annual spending. Obvious, right? But many people fail to see that their lavish lifestyles are the reason they have to work so much.
Spending less also means you need to save less for the future. It takes just $200,000 to fund ten years of a $20,000 lifestyle, whereas it takes $400,000 to fund ten years of a $40,000 lifestyle.
When you learn to live on less, when you keep your profit margin high, you gain the freedom to work less. By maintaining an ambitious saving rate of 50 or even 70 percent in your twenties and thirties, you can retire when you’re 40 years old instead of 65. This gives you forty years of freedom to do what you want with life rather than fifteen.
This table demonstrates the power of profit margin:
Look at those numbers. Let them sink in. Think about the implications.
- With a profit margin of 20%, it takes four years of work to fund one year of operations.
- With a 50% margin, you save enough every year to fund another entire year of operations.
- And at 75%, each year of work funds three additional years of operation.
When you choose to spend less (or to not spend at all), you’re not just boosting your bottom line. You’re also gaining the time and freedom that would have been required to earn that money. Thrift isn’t deprivation. It’s wealth.
The Bottom Line
Frugality is not sacrifice. When you save, that money’s still spent. It’s just not spent on a Mercedes or a big house. It’s spent buying your future freedom. The opportunity cost of starting late, a foolish purchase, or a bad investment isn’t lost income or lost compounding. It’s lost time – lost experience and lost life.
Ultimately, work-life balance is about managing the way you use both time and money.
In some cases your time is more valuable than money, but often its your money that’s worth more. If a new iPad is worth twenty or forty hours of your life, buy it. Otherwise, do yourself a favor: Delay the purchase. Hold on to that money so you can retire sooner instead.
