Why You’re Firing Your Best Employees: The ‘Invisible Employee’ Guide to Compound Interest

I spent most of my twenties firing my best employees because I thought they were just pieces of paper meant for buying mediocre burritos.

Looking back at my bank statements from a decade ago feels like reading a list of wrongful termination lawsuits. Every $20 I spent on a plastic gadget I didn't need was a worker I sent packing. Every $100 I let sit in a zero-interest checking account because I was "scared of the market" was a worker I left sitting in the breakroom. They just stared at the wall and did absolutely nothing.

If you’re a freelancer or a gig worker, you probably do this too. We tell ourselves that our income is too "lumpy" to invest. We wait for the $10,000 month that never seems to come. Meanwhile, we ignore the $10 and $50 workers we have right now.

The truth? We’re just being bad CEOs.

The Confession: I Spent My Twenties Firing My Best People

When you’re a freelancer, your mindset is usually stuck in the "exchange time for money" loop. You finish a project and get a check. You pay your rent. If there’s leftover cash, you treat yourself. It feels like a win.

But here is the psychological shift you need to make today. Stop seeing money as a tool for consumption. Start seeing every single dollar as an Invisible Employee.

These employees are incredible. They don’t need health insurance or vacations. They never sleep. They work around the clock every single day of the year. Their only job is to go out into the world and find more employees to join your team.

When you spend $100 on something stupid, you aren't just losing $100. You are firing a worker who could have worked for you for the next 50 years. At a decent return, that $100 worker was scheduled to bring in thousands of dollars in offspring over their career. By spending it, you basically walked into the office and told your most loyal staff member to clear out their desk.

Think about that 1:00 AM post-gig takeout. It cost $30 today. But if that $30 was invested at age 25, it could have turned into $600 or $1,000 by the time you retire. You didn't just buy a burrito. You spent $1,000 of your future self's money.

The HR Manual: What is Compound Interest, Really?

If your money is the workforce, compound interest is the mechanism that allows them to reproduce.

Most people understand simple interest. You have $100, you earn 10%, and you have $110. Simple. But compound interest is the offspring effect.

Year one: Your $100 worker earns $10. Year two: You now have $110 working for you. That $110 earns $11. Year three: You have $121 working.

The money earns a paycheck. Then that paycheck starts working too. It’s a dynasty. Your original staff builds a family that eventually builds a city. This is why Albert Einstein reportedly called it the eighth wonder of the world. He said, "He who understands it, earns it. He who doesn't, pays it."

If you don’t have these invisible employees working for you, you are probably one of the people paying the interest to someone else’s army. Every credit card balance you carry is you paying for someone else's retirement.

The Hiring Formula: Calculating Your Army’s Growth

To manage a workforce, you need to know the numbers. The math behind your army’s growth looks scary at first. However, it’s actually pretty straightforward.

Let’s break this down into CEO terms:

• A (The Total Force): This is the final amount of money you’ll have.
• P (Initial Staff): This is your principal. This is the starting number of employees you put to work today.
• r (Efficiency): The annual interest rate. How good are your employees at finding more money?
• n (Review Cycles): This is the compounding frequency. How often do your employees report back with their earnings?
• t (Tenure): Time in years. This is the most important variable in the entire equation.

Most people focus on the rate. They want the "hot stock" or the 50% return. But time is the heavy lifter. A mediocre rate over a long time beats a high rate over a short time.

Also, the frequency of compounding matters more than you think. Daily compounding puts your money back to work immediately. Annual compounding makes your money wait until the end of the year to start the next generation.

Look at the difference on a $10,000 staff at 10% interest over 10 years:

By just changing how often the money is reinvested, you gained over $1,200. You didn't have to do a single extra hour of work. If you want to see how your own payroll numbers look over the next few decades, run them through the compound interest calculator. It's the dashboard for your future.

The Promotion Schedule: Using the Rule of 72

As a busy freelancer, you don't always have time for a scientific calculator while waiting for a client to pay an invoice. You need a mental shortcut.

Enter the Rule of 72.

This is a quick way to estimate how long it takes for your workforce to double in size. You just take the number 72 and divide it by your interest rate.

If you’re earning 6% on your money, it will take 12 years to double (72 ÷ 6 = 12). If you can bump that efficiency up to 12%, your money doubles in just 6 years.

A 2% difference in your return isn't just a little bit of money. It is the difference between your army doubling every 9 years versus every 7 years. Over a 30-year career, that is the difference between having a small local business and owning a global conglomerate.

The Office Thief: Factoring in Inflation

Every business has a thief. In the world of investing, that thief is inflation.

Inflation is the invisible tax on your employees' output. If your army grows by 8% this year, but the price of burritos and rent goes up by 3%, your real growth is only 5%.

This is where a lot of people get tripped up. They see a calculator tell them they will have $1 million in 40 years and they think they are set. But $1 million in 2065 will not buy what $1 million buys today. You have to look at the Real Return.

Imagine you invest $10,000 at a 10% return for 20 years. Your account statement will show roughly $67,000. You feel like a genius. But if inflation averaged 3%, that $67,000 only has the purchasing power of about $37,000 in today's money.

The thief took nearly half your gains while you weren't looking. This is why you can't just save cash in a shoebox. Cash in a shoebox is an employee that is slowly being robbed every single day.

The Freelancer’s Strategy: Hiring When You’re Broke

"I don't make enough to invest."

I hear this from my fellow freelancers all the time. When you have a $4,000 month followed by a $1,000 month, the idea of locking away money feels terrifying. You want to stay liquid.

A few months ago, I was chatting with Kaelo Mthembu, a freelance motion designer. At 29, his income is as lumpy as a mountain range. He used to spend everything during his good months because he was so relieved to have cash. Then he’d starve during the bad months. He felt his income was too sporadic for real investing.

We sat down and looked at the numbers. Kaelo’s goal was to hit a $500 monthly investment target. However, he couldn't commit to that every single month.

We changed the strategy. I told him to hire the change from every invoice. If he got a $1,250 check, he sent $50 to his investment account immediately. If he had a $5,000 month, he hired 1,000 workers ($1,000).

By using the compound interest calculator, Kaelo realized that even in his bad months, hiring just 100 new workers ($100) was crucial.

Kaelo is 29. If he averages $500 a month at an 8% return for the next 30 years, he ends up with over $745,000. If he waits until he’s 40 and stable to start investing that same $500 a month? He only ends up with about $275,000.

Those 11 years of waiting cost him nearly half a million dollars.

Why Five Dollars Today Beats Five Hundred Dollars Later

The math is brutal. If you are 20 years old and you hire just 50 workers ($50) a month, you are in a much better position than a 40-year-old trying to hire 200 workers a month.

Time is the multiplier. When you are young, your employees have time to have kids. Those kids have time to have grandkids. By the time you need the money, you have generations of workers.

If you’re a freelancer, stop waiting for the perfect month. Use an app or just manually transfer the leftover dollars from every gig.

Don't think of it as a sacrifice or saving. Think of it as building your empire. Every time you skip a purchase you don't need, you are keeping a high-performing employee on staff.

Your Manager’s Dashboard

Ready to see how many employees you can actually hire?

The best way to get over the lumpy income fear is to see the potential outcome. Use the compound interest calculator to play with the numbers. Toggle the inflation adjustment so you can see the real value in today's dollars.

Check the difference between monthly and daily compounding. See what happens if you increase your efficiency by just 1 or 2 percent.

You are the CEO of your life. Your bank account is your payroll department. Stop firing your best people for the sake of a burrito you won't remember tomorrow. Put them to work and let them build the empire you deserve while you sleep.
