The usual way Good Debt vs. Bad Debt gets answered is with two lists. Good debt: SBA loans, equipment finance, commercial mortgages. Bad debt: Merchant cash advances, credit cards, anything with a daily payment. Sort your options into the right column, and you’re done.
It’s a tidy framework, and it’s not much use, because the same product can be either one depending on what you do with it. A ten-year SBA loan taken out to cover eighteen months of trading losses is bad debt. A short, expensive advance that lets a contractor accept a job worth four times the cost of the money is arguably good debt, even at an eye-watering rate. Most guidance on business loans for small businesses skips this entirely and sorts by instrument, which is the one variable that tells you least.
What actually separates the two is four questions. None of them are complicated, and all of them are easier to answer before you sign than after.
What Is The Money Going To Produce?
This is the whole thing, really. Debt that buys capacity, revenue, or a permanent reduction in costs is a different animal from debt that plugs a hole.
The useful test is whether you can name the output. A machine that lets you take on work you’re currently turning away—that has an output you can point at. A second van, a hire who’ll be billable within a quarter, inventory for a season you’ve already got orders for. You can put a number against each of those and check whether it beats the cost of the money.
If you can’t name what the money will produce, it’s covering something. That isn’t automatically fatal—a genuinely temporary gap, a late payment from a good customer, a one-off legal bill, these are perfectly reasonable things to borrow against. But be clear-eyed about which situation you’re in, because debt that funds an ongoing loss doesn’t fix anything. It buys time, and if time wasn’t the problem, you’ve just made the eventual problem larger and added a payment to it.
The version of this that catches people out is borrowing to cover payroll. Once is a cash flow event. Twice in six months is information about the business model, and no amount of financing addresses it.
What Does It Actually Cost?
Not the rate. The total.
Bank and SBA products quote interest, which you can compare across offers reasonably easily once you’ve added in origination fees and packaging costs. Where it gets murky is the world of factor rates, and this is where small businesses get hurt most often.
A factor rate isn’t an interest rate. Take $50,000 at a factor of 1.35: you repay $67,500, full stop, and if that’s collected over six months of daily debits, the annualised cost lands somewhere north of a hundred percent. Over twelve months it’s roughly half that. Same $17,500 of cost, wildly different price, and the number quoted to you—1.35—doesn’t move either way.
Two consequences follow that most owners don’t expect. Faster repayment makes a factor-rate product more expensive in annualised terms, not less, which is the reverse of how a normal loan works. And prepaying usually saves you nothing at all, because the cost was fixed the moment you signed rather than accruing over time. Some providers offer a discount for early settlement; plenty don’t, and you have to ask.
Whether anyone is obliged to spell this out for you depends entirely on your state. California and New York now require providers to disclose an estimated APR before you sign. A handful of others—Virginia, Utah, Connecticut, Florida, Georgia, Kansas, Missouri, and Texas among them—require disclosures of some kind, though not all of them mandate an APR figure. That still leaves most of the country with no requirement whatsoever, where a factor rate can be quoted with nothing to compare it against.
So do it yourself. Ask two questions: what’s the total dollar amount I repay, and over how long? Everything else is derivable from those two numbers, and any provider reluctant to give you both in writing has told you something important.
Does The Repayment Shape Match The Cash Shape?

A loan can be reasonably priced and still be wrong for you, purely because of when it wants to be paid.
Daily or weekly ACH debits are the clearest example. They work acceptably for a business with genuinely daily receipts—a restaurant, a retailer, anything card-heavy. They are punishing a business that invoices on thirty or sixty day terms, because the money goes out on a fixed schedule that has no relationship to when it comes in. The cost of the advance ends up being the smaller problem; the timing mismatch is what does the damage.
The same logic applies to term length. A machine with seven good years in it, financed over three, creates a squeeze you didn’t need to create. Seasonal working capital funded with five-year amortising debt means you’re still paying for last summer three summers later.
Match the repayment to how the cash actually arrives. It sounds obvious written down, and it’s routinely ignored because the approval was fast and the paperwork was easy.
Can You Get Out?
The last test is reversibility, and it’s the one that gets skipped almost universally because it’s buried in the documents rather than in the headline terms.
Prepayment penalties matter more than people think. If your business improves and you want to refinance into something cheaper, a stiff early-repayment charge can lock you into a rate you’ve outgrown.
Blanket liens matter more still. A UCC-1 filing across all business assets—not just the asset being financed—can make you effectively unfundable elsewhere, because the next lender looks at your filings and sees nothing left to secure against. That’s a characteristic of bad debt entirely independent of price: a loan that forecloses your future options has cost you something that doesn’t appear on the term sheet.
Read the enforcement provisions too. Personal guarantees are normal and you should expect them. Confession-of-judgment clauses are a different matter—they allow a funder to obtain judgment without you appearing to contest it. New York restricted their use against out-of-state businesses back in 2019, but they remain enforceable in plenty of jurisdictions, and forum selection clauses pointing to distant courts are common in this corner of the market.
And then there’s stacking, which is the single clearest marker that debt has gone from good to bad: Taking a new advance to service the ones you already have. Nothing about the underlying business has improved, the payments have gone up, and the timeline has shortened. Once a business is doing this, the financing has stopped being a tool and become the problem. If you’re considering a facility whose actual purpose is to make this month’s payments on another facility, stop and go and talk to a bank about restructuring the whole lot instead.
Reconsidering The Usual Suspects
With those four tests in hand, the familiar categories look a bit different.
Equipment finance is usually good debt, because it’s self-liquidating—the asset generates the cash that pays for it—as long as the term roughly matches the asset’s life.
Commercial mortgages and SBA 504 loans are usually good debt, with the caveat that they tie up capital and borrowing capacity for a long time.
A line of credit is good debt when it breathes: drawn when receivables and inventory build, repaid when they convert. It becomes bad debt the moment it stops touching zero, because at that point you’ve funded something permanent with something temporary and nobody has noticed yet.
SBA 7(a) is cheap and long, which makes marginal deals serviceable, but it’s slow, document-heavy, and generally comes with a personal guarantee and a lien on most of what you own.
Credit cards are fine as float and expensive as term debt. Carrying a balance for a month between an invoice and a payment is unremarkable. Carrying one for two years is a decision you’ve made by accident.
Revenue-based finance and merchant cash advances are expensive, and occasionally that’s a rational trade—genuinely short-term, genuinely certain payback, an opportunity that disappears if you wait three weeks for a bank. Mostly it isn’t, and the speed is doing the selling rather than the price.
Good Debt Goes Bad On Its Own Sometimes
One more thing worth holding onto: The debt doesn’t change, but the thing it funded can.
A well-priced, well-structured loan against a piece of equipment becomes a problem if the contract that justified the equipment doesn’t materialise. The obligation is fixed and the outcome was always variable. That’s not a mistake in the borrowing, it’s the nature of borrowing, and it’s the argument for running a downside case before you sign rather than only the plan.
While we’re at it: Interest is generally deductible, and that’s a genuine benefit worth factoring in. It is not, however, a reason to borrow. Getting a quarter of the cost back at tax time doesn’t convert expensive debt into cheap debt, and “it’s a write-off” has justified a lot of bad decisions.
Three Questions Before You Sign
Strip it all back and it comes to this. What will this money produce, in dollars? What will it cost me in total, in dollars, and over what period? And what happens if the plan is twenty percent worse than I expect?
If you can answer all three and the numbers still work, it’s probably good debt regardless of what product it’s called. If you can’t answer any of them, the product name won’t save you.
