When to Use Debt vs. Cash to Grow (Without Giving Up Your Company or Choking on Payments)

Somewhere around the seven-figure mark, the growth decisions get bigger and the way you pay for them starts to matter as much as the decisions themselves. A new hire, a second location, a bigger inventory buy, an acquisition. Each one is a bet on the future, and each one has to be funded with something. Cash from the bank account. Debt from a lender. Equity from an investor. Or some combination of the three.

Most owners default to one of two extremes. They either pay for everything out of pocket and starve the business of the cash it needs to survive a bad month, or they take whatever money is offered first and end up with payments that eat every dollar of margin they worked to build. Neither one is a strategy. Both are reactions.

The real cost of using your own cash

Using cash feels safe because there is no payment and no interest. It is also the most expensive money you have, because it is the only money that protects you when things go wrong. Every dollar you spend from the bank account to fund growth is a dollar that is not there to cover payroll when a big client pays late, or to survive the quarter a tariff hike wipes out your margin.

I see this constantly at CEO Finance Academy. A founder funds a big expansion with cash, the expansion takes six months longer than planned to pay off, and now they are running the whole business on a razor-thin buffer. The growth worked. The financing broke them. The lesson is not to stop growing. It is to stop using your last line of defense to pay for it.

When debt actually makes sense

Debt is the right tool when the thing you are buying pays for itself. Equipment that increases capacity. Inventory you know you can turn. A marketing channel with a proven return on ad spend. In every one of these cases, the asset generates cash that can service the loan, which means the growth is funding itself instead of draining your reserves.

The two numbers that decide whether debt works are the cost of the money and the timeline of the return. If you are borrowing at 12% to fund something that pays back in 90 days, the math works. If you are borrowing at 12% to fund something that pays back in two years, you are paying interest on interest while you wait, and a single slow quarter turns a smart bet into a squeeze.

This is why I tell owners to match the financing to the life of the asset. Short-term needs get short-term money. Long-term investments get longer-term debt. Using a one-year line of credit to buy something that takes three years to pay off is how healthy businesses end up refinancing in a panic.

Revenue-based financing: the middle ground most owners miss

Revenue-based financing, or RBF, is the option a lot of seven and eight-figure owners have never seriously considered. Instead of fixed monthly payments, the lender takes a percentage of your revenue until the advance plus a fixed fee is paid off. When revenue is up, you pay more and finish faster. When revenue is down, you pay less and the pressure eases.

It is not cheap. The effective cost is usually higher than a traditional loan. But it has one feature that makes it worth understanding: the payment flexes with your cash flow. For a seasonal business, a company with lumpy client payments, or a founder funding inventory or ads where the return is real but the timing is unpredictable, that flexibility can be worth the premium.

The mistake to avoid is treating RBF like free money because there is no fixed payment. The cost is real and it compounds if revenue stalls. Use it for growth you can measure, not for plugging a hole in the P&L.

Equity: the most expensive money there is

Equity feels cheap because there is no payment and no interest. It is the most expensive money you will ever raise, because you are paying for it forever. A 20% stake sold to fund a one-time expansion is 20% of every dollar of profit and every dollar of exit value for the rest of the company's life.

There are moments when equity is the right answer. You are building something with no near-term cash flow that needs years of runway. You need a partner who brings more than money, like distribution or expertise. You are intentionally trading ownership for speed and you have done the math on what that ownership is worth. Outside of those cases, equity is usually the last resort, not the first.

The founders I respect most are the ones who treat ownership like the asset it is. They use debt and cash to grow, they protect their equity, and they only sell pieces of the company when the return on that sale is obvious and permanent.

How to actually decide

When a growth decision lands on my desk, I walk it through the same four questions every time:

1. 1.Does this investment pay for itself, and on what timeline? If the answer is no, it is a cash purchase or it is not a purchase yet.
2. 2.What is my cash buffer after I fund this, in weeks of runway? If it drops below 8 weeks, I am using the wrong money.
3. 3.Can the asset's cash flow service the debt without me crossing my fingers? Run the downside case, not the upside case.
4. 4.Am I giving up ownership because I need to, or because I did not model the other options first?

Most of the time, the answer that comes out of those four questions is some combination of cash and debt, with equity off the table. That is the sweet spot for a seven or eight-figure business. You grow faster than cash alone would allow, you keep your ownership, and you keep a buffer that lets you sleep at night.

The bigger shift

Underneath all of this is a change in how you think about money in the business. Early on, cash is something you chase. At seven and eight figures, capital becomes a tool you choose between, and the owners who scale are the ones who get deliberate about which tool they reach for and why.

This is the same conversation I have with founders on Building The Business. The companies that grow without breaking are not the ones with the most money. They are the ones who learned to fund growth with the right kind of money at the right time.

If you are staring down a growth decision and not sure which kind of capital fits, that is exactly what we help with at CEO Finance Academy. We can model the options against your real numbers, build the cash flow forecast that tells you what your buffer looks like after you pull the trigger, and help you walk into the decision with your eyes open.
