Your Freedom Number is probably wrong. Here's how to fix it.

Two updates from the vending search covered in Issue 5.

The larger listing is gone. The seven-location, $98.5K portfolio I had an NDA pending on was taken off the market before the broker released the CIM. No explanation beyond "seller changed their mind." It happens. You do the preliminary work, the seller decides they're not ready, and the deal disappears before you ever see the financials. First real lesson worth passing along: sellers are not always committed to selling, even when they have an active listing. The willingness to pull the deal at any point before LOI is real — reason not to invest too much analysis before you have the CIM in hand.

The smaller listing is moving forward. I had the four-machine package listed as a single location in Issue 5. The broker clarified this week: it's actually two locations with four machines split across them, and he wants to schedule time for me to visit both.

Two locations is a different operational picture than one. Revenue is already diversified across sites, which reduces the risk that one location relationship going sideways takes the whole business with it. A site visit also means two stops, two sets of location contacts to evaluate, two data points on foot traffic and machine performance.

I scheduled the visit. Until I'm standing in front of the machines and talking to someone who knows the locations, the financial analysis only tells me so much. More on this in Issue 7 once I've been out there.

Issue 3 introduced the Freedom Number and walked through the formula at a high level. A fair number of you have run the calculator since then, and I've been thinking about the ways that calculation tends to go sideways.

Three specific mistakes keep coming up. Two of them make the gap look bigger than it is. One makes you think you're closer than you are. All three are fixable with a few minutes of honest math.

Before the mistakes: the formula, stated cleanly.

Step 1: Monthly essential expenses. Pull your last three months of bank statements. Add up everything that doesn't go away if the W2 stops: housing, utilities, food, insurance (health, home, auto), transportation, and minimum debt service. This is the floor. What you actually need, not what you currently spend.

Step 2: Subtract existing outside income. If you have income coming in from anywhere outside your W2, subtract it from your essential expenses. A rental generating $800/month, a consistent dividend, anything. The remainder is your gap. If you have nothing outside your W2, the gap equals your essential expenses.

Step 3: Multiply the gap by 1.5. That's your Freedom Number.

Write the number down before continuing. The rest of this issue is more useful when you have a specific target in front of you.

The most common error, and the one that produces the most damage: running the essential expenses step using optimistic numbers.

Most engineers, when asked what their monthly expenses are, give a figure that reflects what they think they should be spending, not what they actually spend. They remember the mortgage and the car payment. They forget the insurance renewal that hits once a year and averages to $180/month. They forget the quarterly tax estimate. They forget the dental visit that isn't covered. The irregular-but-real expenses that don't show up in any single month but show up reliably across twelve.

The fix is a trailing three-month average from actual transactions, not memory. Most banks and credit card portals will export this. Add everything that isn't obviously discretionary: dining out is discretionary, groceries aren't. Travel is discretionary, your AAA membership probably isn't. When in doubt, leave it in. The cost of undercounting is a Freedom Number that's too low, which means a DR plan that fails the first time it actually needs to run.

This one deserves its own section because the magnitude of the error is large enough to materially change the calculation, and because engineers with employer-sponsored coverage have almost no intuition for the real cost.

If you've had employer-sponsored health insurance for most of your career, your mental model for healthcare cost is whatever shows up as the employee contribution on your paystub: typically $150 to $400 per month for an individual, or $400 to $800 for a family. That contribution is the employee share only. Employers commonly cover 70 to 80 percent of the total premium. When the W2 stops, the full cost lands on you.

An ACA marketplace plan for a healthy 50-year-old individual runs $600 to $900 per month for a mid-tier plan in most markets. For a family of four, that range climbs to $1,800 to $2,600. These are not worst-case figures. They're what current marketplace plans actually cost before any income-based subsidies apply.

If you ran your Freedom Number without a healthcare line item because it's currently invisible inside your paycheck, add it back in and re-run. For an individual, that's roughly $700 to $800 per month added to your baseline. For a family, more.

This one cuts the other direction. Engineers who anchor to their monthly take-home when thinking about the Freedom Number consistently make the gap feel larger than it actually is.

Here's how it happens. Your paycheck hits the account at $9,500 per month. When someone asks how much outside income you'd need to make the W2 optional, $9,500 is the number that comes to mind, because that's what your life currently runs on.

But take-home pay includes everything you spend, not just what you need. The restaurants, the subscriptions, the weekend trips, the reflexive Amazon purchases. Those are real expenses and you're accustomed to them, but they're discretionary. The Freedom Number is built on what isn't.

Pull up those bank statements and separate the essential from the optional. Housing, utilities, food, insurance, transportation, minimum debt service — that's the floor. For most senior engineers in their 40s and 50s with established households, that essential layer runs $5,000 to $7,500 per month, not the full take-home figure.

Once you have an honest Freedom Number, the useful question shifts: what closes this gap, and on what timeline? Both tracks have realistic answers.

The Buy Track. A business acquisition generating $70,000 to $90,000 per year in seller's discretionary earnings nets roughly $45,000 to $60,000 after debt service on a typical SBA-financed deal. That's $3,750 to $5,000 per month in additional cashflow. For a senior engineer with essential expenses in the $7,000 to $8,500 range, that's a Freedom Number somewhere between $10,500 and $12,750, and one acquisition at this size covers roughly a third to half of it. A second deal, a Build Track asset, or both close the remainder. Timeline from starting a search to closing: nine to eighteen months. Cashflow starts the month after close.

The Build Track. A newsletter or digital product business takes longer but requires less upfront capital. A well-run newsletter realistically generates $2,000 to $5,000 per month at the twelve-month mark. At twenty-four months that range can extend to $5,000 to $15,000. The capital requirement is a fraction of what a business acquisition demands, and the asset compounds differently.

The Dual Track. If your Freedom Number is higher or capital is limited, running one track while building toward the other is the architecture most people end up on. A modest acquisition covering half the gap while a Build Track asset compounds toward the other half is a real plan with documented precedent.

The point: once you have a correct Freedom Number, you're not trying to replace a salary. You're trying to hit a specific monthly cashflow target against your actual expenses. That's a more tractable problem, with real solutions and documented timelines. The Income Stack Spotlight below shows what one path through the Buy Track looks like with concrete numbers attached.

Every few issues I feature a real cashflow asset with real numbers. Asset type, capital in, annual cashflow, weekly time.

The cleaning business build in Issue 5 covered the scratch-start model. This spotlight covers the acquisition side: what it looks like to buy a cleaning or home services business that already runs.

That net — roughly $4,000/month on a clean deal — is a meaningful contribution toward most Freedom Numbers in this readership. Businesses in this range trade on BizBuySell regularly.

What makes the category interesting for engineers: the failure modes are operational, not technical. Cleaning businesses break down in three predictable ways — owner dependency (no documented systems), customer concentration (top five clients at 40%+ of revenue), and crew turnover. All three are due diligence questions you can answer before closing. None of them are hidden the way technical debt is hidden in a software acquisition.

What to verify: percentage of revenue from recurring versus one-time clients, how many hours per week the current owner works inside the business versus overseeing it, and how long the core staff have been with the operation. Two-plus years of crew tenure is an asset you're acquiring. Six months is a risk you're inheriting.

Next issue: what the acquisition search actually looks like from the inside. I'll walk through what I've learned reviewing listings, having real broker conversations, and passing on deals that didn't clear the screen. Where the buy box is tightening, and what the pattern recognition looks like after a few dozen listings.

More next week.
